The table that represents the function y =1/3 x + 4 is the second table. This can be seen by comparing the input and output values of the given tables.
What is function?A function defines the relationship between two variables, wherein one variable depends on the other. In other words, a function is a rule or mapping from one set of values, known as the domain, to another set of values, known as the range.
The table that represents the function y =1/3 x + 4 is the second table. This can be seen by comparing the input and output values of the given tables.
The second table's input values are (6, 9, 12) and the output values are (6, 9, 12). This is equal to the equation y = 1/3 x + 4, where 1/3 x + 4 = x.
The other tables do not represent the function y = 1/3 x + 4. For example, the first table has input values of (0, -3, -6) and output values of (4, 3, 2), which do not match the equation y = 1/3 x + 4.
The third table has input values of (0, 3, 6) and output values of (4, 6, 8), which also do not match the equation y = 1/3 x + 4.
Finally, the fourth table has input values of (3, 6, 9) and output values of (5, 7, 9). This does not match the equation y = 1/3 x + 4 either.
Therefore, the table that represents the function y =1/3 x + 4 is the second table.

find the simple interest. round to the nearest cent
principal = $600
rate = 2%
time in years = 2
Answer:
To find the simple interest on a principal of $600 at a rate of 2% for a time period of 2 years, we can use the formula:
Simple Interest = (Principal * Rate * Time)
where Rate is the annual interest rate as a decimal, and Time is the time period in years.
In this case, we have:
Principal = $600
Rate = 0.02 (2% expressed as a decimal)
Time = 2 years
So, the formula becomes:
Simple Interest = ($600 * 0.02 * 2)
= $24
Therefore, the simple interest on a principal of $600 at a rate of 2% for 2 years is $24.

tycho plans his running training. each week he wants to go for a run on the same weekdays. he never wants to go for a run on two consecutive days. but he wants to go for a run two days a week. how many different weekly plans meet those conditions?
There are 4 different weekly plans that meet the condition
If Tycho wants to go for a run on the same weekdays every week, there are 7 choices for the first day of the week, 6 choices for the second day of the week, and 5 choices for the third day of the week (since he can't run on two consecutive days).
However, we have to be careful not to overcount the number of plans that meet the conditions. For example, if Tycho chooses Monday and Tuesday as his running days, that's the same as choosing Tuesday and Monday.
To avoid overcounting, let's first count the total number of possible plans, regardless of whether they meet the conditions or not. We can choose any two days of the week for Tycho to run, which can be done in 7 choose 2 ways (or C(7,2) ways), since order doesn't matter.
C(7,2) = 7!/(2!(7-2)!) = 21
So there are 21 possible plans, regardless of whether they meet the conditions or not.
Now let's count the number of plans that meet the conditions. Since Tycho wants to run on two days a week and not on consecutive days, there are only two possible patterns: (1) run on Monday and Thursday, or (2) run on Tuesday and Friday.
Each pattern can be done in 2 ways: either run on Monday and Thursday, or run on Thursday and Monday. Similarly, either run on Tuesday and Friday, or run on Friday and Tuesday.
So there are 4 plans that meet the conditions: (Monday, Thursday), (Thursday, Monday), (Tuesday, Friday), and (Friday, Tuesday).
Therefore, there are 4 different weekly plans that meet the condition

mrs. takac throws a ball upward from atop a 506 foot tall building and the ball's height, h, in feet after t seconds is given by the equation: the ball lands on a balcony that is 218 feet above the ground. how many seconds was it in the air?
The number of seconds that the ball was in the air is approximately 5.11 seconds
To find the time the ball was in the air, we need to find the time when the ball hits the balcony, which is located 218 feet above the ground.
Let's set h = 218 in the equation h = -16t^2 + 48t + 506 and solve for t
218 = -16t^2 + 48t + 506
Simplifying, we get
16t^2 - 48t - 288 = 0
Dividing both sides by 16, we get
t^2 - 3t - 18 = 0
Using the quadratic formula, we can solve for t:
t = (-b ± sqrt(b^2 - 4ac)) / 2a
where a = 1, b = -3, and c = -18
t = (3 ± sqrt(3^2 - 4(1)(-18))) / 2(1)
t = (3 ± sqrt(105)) / 2
We can ignore the negative solution because time cannot be negative. Therefore, we have
t = (3 + sqrt(105)) / 2
t ≈ 5.11 seconds

The probability that the person selected will be someone whose response is never and who is a woman is 3/7.
The probability that the person selected will be someone whose response is never and who is a woman can be found by using conditional probability.What is conditional probability?Conditional probability is the likelihood of an event occurring given that another event has already occurred. The probability of event A happening given that event B has already occurred is known as conditional probability.Mathematically, the formula for conditional probability is:P(A|B) = P(A ∩ B) / P(B)Where,P(A|B) represents the probability of event A given that event B has already occurred.P(A ∩ B) represents the probability of both A and B occurring.P(B) represents the probability of event B occurring.The given scenario states that the person selected should have two attributes: the response never and the gender woman. Let A be the event that the person selected has a response never and B be the event that the person selected is a woman. Therefore, we need to find the probability of event A given event B.P(A|B) = P(A ∩ B) / P(B)Therefore, we need to find the probability of both A and B occurring and the probability of event B occurring.P(B) = 70/120P(B) = 7/12There are 50 women in the group.

there is a group of five children, where two of the children are twins. in how many ways can i distribute $8$ identical pieces of candy to the children, if the twins must get an equal amount of candy?
There are 1960 different ways to distribute 8 identical pieces of candy to the five children, where the twins get an equal amount of candy.
First, distribute the candy to the twins.
Split the 8 pieces of candy into two equal parts for the twins using combinations:
C(8, 4)
This means selecting 4 pieces of candy from the 8 identical pieces for one twin, and the remaining 4 pieces will automatically go to the other twin.
C(8, 4) is calculated as:
[tex]^8C_4 = \dfrac{8!}{4!(8-4)!}[/tex]
= 8! / (4! * 4!)
= (8 * 7 * 6 * 5) / (4 * 3 * 2 * 1)
= 70
Now, you have distributed 4 pieces of candy to each of the twins. Y
In this case, you have 6 pieces of candy to distribute among 3 children, and you can use two dividers (bars) to separate the candy for each child.
This can be represented as:
OO|OO|OO
The two bars split the 6 pieces of candy into three sections for the three children.
So, you have C(6 + 2, 2) ways to distribute the remaining candy:
[tex]^{6+2}C_2 = \dfrac{8!}{2!(8-2)!}[/tex]
= 8! / (2!(8 - 2)!)
= 8! / (2! * 6!)
= (8 * 7) / (2 * 1)
= 28
Now, the total number of ways to distribute the candy
Total ways = C(8, 4) * C(8, 2) = 70 * 28 = 1960
So, there are 1960 different ways to distribute.

After Simon fully charges his electric car, he can drive for up to 350 miles before it runs out of battery. Simon's car was fully charged this morning, and he has driven 140 miles since then.
Let x represent how many more miles Simon can drive without running out of battery. Which inequality describes the problem?
the inequality that describes the problem is x ≤ 210, meaning that Simon can drive at most 210 more miles before his electric car runs out of battery.
If Simon has driven 140 miles since fully charging his car, then the amount of charge remaining in the battery can power the car for x miles. We can set up the following inequality to represent this situation:
x ≤ 350 - 140
The amount of charge left in the battery is shown on the right-hand side of the inequality and is equal to the maximum amount of charge the battery can store (350 miles) minus the amount of charge that has already been utilised (140 miles). The left-hand side of the inequality displays the number of miles Simon can travel until his battery runs out, which is either less than or equal to the battery's remaining charge.

8. how many cans of mandarin oranges are needed to serve a part of 200 people if each person is to receive a 3 ounce serving and each can weighs 5 pounds 10 oz ( 9 ounces of that as liquid which you will discard)?
8 Cans of mandarin oranges are needed to serve a part of 200 people if each person is to receive a 3-ounce serving and each can weights 5 pounds 10 oz (9 ounces of that as liquid which you will discard).
Given that each can of mandarin oranges weighs 5 pounds 10 oz (9 ounces of that as liquid which you will discard).We are to find out how many cans of mandarin oranges are needed to serve a part of 200 people if each person is to receive a 3-ounce serving.
Convert 3 ounces into pounds and ounces
3 ounces = 3/16 pound (1 pound = 16 ounces)
Amount of mandarin oranges required by one person = 3/16 pound
Amount of mandarin oranges required by 200 people = 200 * (3/16) pound
Amount of mandarin oranges required by 200 people = 37.5 pound
Convert the amount of mandarin oranges required into cans
Weight of one can of mandarin oranges = 5 pounds 10 oz = (5*16 + 10) ounce = 90 ounce
Weight of mandarin oranges only in one can = 90 ounce - 9 ounce = 81 ounce (9 ounce is liquid which you will discard)
Number of cans required = (total weight required) / (weight of one can)Number of cans required = (37.5 * 16) / 81 Number of cans required = 7.4 cans

A random group of adults was asked to complete a survey regarding the number of pets in their households. No two adults sur came from the same household. The number of households, , with no pets is one fourth of the number of households with multip Which of the following equations represents this situation if of the households have a single pet?
The equation representing the situation is 4x = y - 1, where x is the number of households with one pet and y is the total number of households. This can be answered by the concept of Simple equation.
Let's assume that there are x households with a single pet. The number of households with no pets is given as one-fourth of the number of households with multiple pets, which means there are 4 times as many households with multiple pets as there are households with no pets. Let's represent the total number of households as y.
Therefore, we can say that the number of households with no pets is (y - x)/4, and the number of households with multiple pets is 3(y - x)/4 since there are 4 times as many households with multiple pets as there are households with no pets.
Now, we can use the given information that the number of households with no pets is one-fourth of the number of households with multiple pets to write the equation:
(y - x)/4 = x/3
Solving for y, we get:
y = 4x + 3x/4 = 16x/4 + 3x/4 = 19x/4
But we are given that the total number of households y includes the households with one pet, so we can write:
y = x + (y - x)/4 + 3(y - x)/4 = x + y/4
Substituting the value of y from the previous equation, we get:
19x/4 = x + 19x/16
Solving for x, we get:
x = 16/3
Therefore, the equation representing the situation is 4x = y - 1, where x = 16/3 and y = 19x/4, which simplifies to:
4(16/3) = y - 1
y = 21
Therefore, there are 16 households with one pet and 5 households without any pets.

What is pie chart?A pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice is proportional to the quantity it represents. Pie charts are commonly used in business, media, and other fields to represent percentages, ratios, and proportions. They are useful for quickly understanding the relative sizes of different categories or groups in a dataset.
Here,
To create a pie chart from the given data, we first need to calculate the angle of each slice of the pie chart. To do this, we use the following formula:
Angle for a slice = (Frequency of the category ÷ Total frequency) × 360°
Using the given data, we can calculate the angle of each slice as follows:
Angle for apple = (12 ÷ 72) × 360° = 60°
Angle for banana = (18 ÷ 72) × 360° = 90°
Angle for guava = (6 ÷ 72) × 360° = 30°
Angle for grapes = (36 ÷ 72) × 360° = 180°
Now, we can draw a circle and divide it into 12 parts (each representing 30 degrees). Then, we can draw the slices of the pie chart using the angles we calculated above.

Therefore , the solution of the given problem of percentage comes out to be earned 6.1% from the selling of the oranges.
What is percentage, exactly?In statistics, "a%" refers to a figure or a statistic that is expression as a percentage of 100. The letters "pct," "pct," and "pc" are also rare abbreviations. It is typically represented by the symbol "%," though. There are no indicators and a flat ratio to the overall amount. In reality, percentages are numbers because their sum almost always equals 100.
Here,
Let's suppose that the lady purchased x oranges.
She charged 60gp for each orange she sold, for a total of 60x gp.
She earned a profit of 3.05 GHC, making her overall profit
=> 3.05 GHC = 305p.
Her cost price (50gp) plus her profit (305p) would equal her total income (selling price), which would be 355gp.
=> 60x = 355
=> x = 355/60
=> x = 5.9167
She consequently purchased six bananas.
b) Since she paid 50gp for the container of oranges, their cost would be 50gp.
c) The total sale price of the oranges would be 360gp, or 60gp for each orange multiplied by 6.
d) She would have earned a profit of (profit/cost price) x 100%.
She made 305p, or 3.05 GHC, in earnings.
Her cost was 50gp, so
=> 6.1% = (3.05/50) * 100%.
She thus earned 6.1% from the selling of the oranges.

To calculate the time, we need to use the formula,
Time required = (distance/speed)
It is given that the distance between Mount Hood and your location is 20 river miles, and the speed of the lahar is 40 miles per hour. Therefore, the time it will take for the lahar to arrive is calculated as:
Time required = distance/speed
Time required = 20 miles / 40 miles per hour
Time required = 0.5 hours = 30 min
to determine the expected arrival time at your location,
Total time required = 3.00 + 0.30 = 3.30 pm.
Therefore we can conclude that we should expect the lahar to arrive at your location at 3:30 pm.

6. f(x)g(x)+h(x) = 20x3-4x. This answer is arrived at by using the rules of algebra and the values of the given functions.
7. f(x)g(x) = -15x2 - 18x - 15
What are polynomials?Polynomials are algebraic expressions consisting of variables and coefficients that are combined through addition, subtraction, multiplication and division operations. For example, the polynomial 4x² + 3x - 5 can be written as the sum of 4x², 3x and -5.
6. In order to calculate f(x) g(x)+h(x), it is necessary to first multiply f(x) and g(x). Since f(x)=4x and g(x) = 5x2-4, it follows that f(x)g(x)=20x3-4x. Next, it is necessary to add h(x) to this product. Since h(x) = 9x, it follows that f(x)g(x)+h(x) = 20x3-4x+9x = 20x3-4x. Since each coefficient is correctly represented in the answer, it follows that the correct answer is 20x3-4x.
Multiplying f(x) and g(x) gives the product of 20x3-4x, and adding h(x) to this product gives the sum of 20x3-4x. As each coefficient is correctly represented in the answer, the correct answer is 20x3-4x.
7. The product of two polynomials is found by multiplying each term of one polynomial by each term of the other polynomial. This is known as the FOIL method (First, Outer, Inner, Last).
The first term is the product of the first terms of each polynomial, which is 3x x 4x = 12x2.
The second term is the product of the outer terms, which is 3x x -5x = -15x2.
The third term is the product of the inner terms, which is 5 x -5x = -25x.
Finally, the fourth term is the product of the last terms of each polynomial, which is 5 x -3 = -15.
We can now combine the terms to get the product of the two polynomials, which is:
f(x)g(x) = -15x2 - 18x - 15.
Therefore, the correct coefficient for each term is -15x2 for the first term, -18x for the second term, and -15 for the third term.

The statement that best describes the chord of a circle is a chord is any segment in which the end points are found on the arc of the circle. (option a).
A chord of a circle is a line segment that connects two points on the circle. The two endpoints of the chord are called the endpoints of the chord, and they lie on the circumference of the circle.
Therefore, option (a) that states that a chord is any segment in which the endpoints are found on the arc of the circle is the correct answer.
It is important to note that a chord does not have to pass through the center of the circle. If a chord passes through the center of the circle, it is called a diameter. A diameter is the longest chord of a circle, and it divides the circle into two equal parts called semicircles.
The correct answer to the question is option (a), which states that a chord is any segment in which the endpoints are found on the arc of the circle.

studies have shown that bats can consume an average of 10 mosquitoes per minute. what is the probability that a bat does not consume any mosquitoes in a 30-second interval?
The probability that a bat does not consume any mosquitoes in a 30-second interval is 0.0067379 or 0.67%.
In this case, the average rate of mosquitoes consumed by a bat is 10 per minute.
To find the rate for a 30-second interval, calculate the rate for 1 minute and then adjust it for the 30-second interval:
Average rate for 1 minute = 10 mosquitoes
Rate for 30 seconds = [tex]\dfrac{10 \,mosquitoes}{1 \,minute} \times \dfrac{1}{2}[/tex]
= 5 mosquitoes
The Poisson distribution probability mass function is given by:
[tex]\[ P(X = k) = \dfrac{e^{-\lambda} \cdot \lambda^k}{k!} \][/tex]
Where:
[tex]\(\lambda\)[/tex] is the average rate of events.
In this case, to find the probability that k = 0.
So, let's plug in the values:
[tex]\(\lambda = 5\)[/tex]
[tex]\(k = 0\)[/tex], back to the formula as
[tex]\[ P(X = 0) = \dfrac{e^{-5} \cdot 5^0}{0!} \][/tex]
Calculating the probability as
[tex]\[ P(X = 0) = e^{-5}[/tex]
[tex]= 0.0067379[/tex]
Therefore, the probability is 0.0067379 or 0.67%.

in how many ways can you choose a committee of size 10 with at least 2 men if there are 30 women in the club and 20 men in the club lsing set difference?
Therefore, the number of ways to choose a committee of size 10 with at least 2 men is: 961379655
We are to find the number of ways to choose a committee of size 10 with at least 2 men if there are 30 women in the club and 20 men in the club using set difference. We can use the following formulas: (1) A set difference B = {elements of A that are not in B} (2) The number of ways to choose k elements from n elements is represented by nCk.
(3) The complement of an event E is the set of all outcomes in the sample space that are not included in the outcome of E.(4) If E is an event, then P(E) represents the probability of E happening.(5) P(E') + P(E) = 1 (where E' is the complement of E).
To choose a committee of size 10 with at least 2 men, we can first find the total number of committees possible (which includes committees with 0, 1 or 2 men) and then subtract the committees that do not have at least 2 men. So, the total number of ways to choose a committee of size 10 is 50C10. Using the formula nCk = n!/k!(n-k)!, we can write it as follows: 50C10 = 50! / 10!40! = 10272278170.
The number of ways to choose a committee of size 10 with no men is 30C10.Using the formula nCk = n!/k!(n-k)!, we can write it as follows:30C10 = 30! / 10!20! = 30045015. The number of ways to choose a committee of size 10 with exactly 1 man is (20C1) * (30C9).Using the formula nCk = n!/k!(n-k)!, we can write it as follows:(20C1) * (30C9) = 20! / 1!19! * 30! / 9!21! = 47152200.
The number of ways to choose a committee of size 10 with exactly 2 men is (20C2) * (30C8). Using the formula nCk = n!/k!(n-k)!, we can write it as follows:(20C2) * (30C8) = 20! / 2!18! * 30! / 8!22! = 47502000. Therefore, the number of ways to choose a committee of size 10 with at least 2 men is:50C10 - 30C10 - (20C1) * (30C9) - (20C2) * (30C8)10272278170 - 30045015 - 47152200 - 47502000 = 961379655 Ways.
