Answer:
Slope m = 1/3
Step-by-step explanation:
Slope of the line can be found by taking two points on the line, (x1, y1) and (x2, y2)
Find the difference in y coordinates, y2 - y1 (called rise)
Find the difference in corresponding x coordinates x2 - x1 (called run)
Rise/Run gives the slope
Two distinguishable points on the line graph are (0, 2) and (3, 3)
rise = 3 - 2 = 1
run = 3 - 0 = 3
Slope = 1/3

Find the area of the parallelogram below:
What is the area?
Answers
Answer:
The area of the parallelogram is 630.4 square units, to the nearest tenth.
Step-by-step explanation:
The formula to find the area of a parallelogram is:
[tex]A=bh[/tex]
where b is the base and h is the height.
For the given parallelogram ABCD, BC and AD are the bases and h is the height. Therefore, we need to calculate the height, h, before we can calculate the area of the parallelogram.
The height of the parallelogram is also the side opposite angle 62° in the right triangle of the given diagram. As we also know the hypotenuse of this triangle, we can use the sine trigonometric ratio to find "h".
[tex]\boxed{\begin{minipage}{9 cm}\underline{Sine trigonometric ratio} \\\\$\sf \sin(\theta)=\dfrac{O}{H}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]
Given:
θ = 62°O = hH = 21Therefore, the expression for h is:
[tex]\implies \sin 62^{\circ}=\dfrac{h}{21}[/tex]
[tex]\implies h=21\sin 62^{\circ}[/tex]
Given the base of the parallelogram is 34 units, substitute b = 34 and the expression for h into the formula for the area:
[tex]\begin{aligned}\implies \textsf{Area}&=34 \cdot 21\sin 62^{\circ}\\&=630.424581...\\&=630.4\; \sf square\;units\;(nearest\;tenth) \end{aligned}[/tex]
Therefore, the area of the parallelogram is 630.4 square units, to the nearest tenth.
Calculate the money you will have in the following accounts after 5 years assuming you earn simple interest,

54. you deposit $1800 in an account with an annual interest rate of 3.8%
Answers
We will have $840 and $2142 respectively. The solution has been obtained by using simple interest.
What is simple interest?
Simple Interest (S.I.) is a way for figuring out how much interest will accrue on a specific principal sum of money at a certain rate of interest.
We know that amount after simple interest is given by
A = P (1 + rt)
We are given that $700 are deposited in an account with an annual interest rate of 4%.
Here,
P = $700
r = 4%
t = 5 years
On substitution, we get
⇒A = 700 (1 + (0.04 * 5))
⇒A = 700 (1 + 0.2)
⇒A = 700 (1.2)
⇒A = $840
Similarly, in the second case,
P = $1800
r = 3.8%
t = 5 years
On substitution, we get
⇒A = 1800 (1 + (0.038 * 5))
⇒A = 1800 (1 + 0.19)
⇒A = 1800 (1.19)
⇒A = $2142
Hence, we will have $840 and $2142 respectively.

The infographic would be less appealing to visual learners than the text.
It is impossible to understand the infographic without the text.
The text is more accurate than the infographic.
The conditional probability that a randomly chosen student studies every day, given that the student passes a math test is O P(M|S). The correct option is A.
P(M|S) is the probability that a randomly chosen student passes a math test given that the student studies every day. But, the question is asking for the probability that a student studies every day given that the student passes a math test.
Considering an P(M|S) situation,
Option D: P(SM) is incorrect because it means the probability that both events S and M occur simultaneously.
Option C: P(S) and P(M) is incorrect because it shows the probabilities of two individual events, not the probability of one event given that the other event has occurred.
Option B: P(M AND S) is incorrect because it means the probability that both events M and S occur simultaneously.
The given problem is based on Conditional Probability Notation to Describe Events. The notation used for conditional probability is P(A|B). Where A and B are two events, the notation represents the probability of event A occurring, given that event B has occurred. Conditional probability can be described as the probability of one event happening given that another event has already happened.

Explanation:
The figure can be split into 3 smaller shapes; a rectangle a square and a triangle.
The rectangle's area is found by multiplying its width by its height:
6 x 8 = 48sq km.
The square's area is found by multiplying its width and height:
2 x 2 = 4sq km.
The triangle's area can be found using the formula (base x height) / 2. The height is given as 7km, the base is given as 8 plus an unknown amount. That unknown amount can be found by noticing that the length of the top 6km of the top rectangle plus the 2km distance of the top of the small square add up to the same distance as the 5km side plus the unknown amount.
From this, we see that 6 + 2 = 5 + unknown distance, so the unknown distance must be 3 (8 = 5 + 3).
Now by adding this 3km to the known 8km of the triangles base, we get a base of 11km.
From here we use the formula (base x height) / 2 to find the triangle's area:
(11 x 7) / 2 = 77/2 = 38.5sq km.
Now by adding up every separate shapes area, we get the final area of the figure.
38.5 + 48 + 4 = 90.5sq km.

Find the first five non-zero terms of Maclaurin series (Taylor series centered at x=0) for the function below as well as radius of convergence.
f(x)=xe^x
Answers
Answer:
To find the Maclaurin series for $f(x) = xe^x$, we can use the formula for the Maclaurin series of $e^x$ and differentiate the product term by term:
$$e^x = \sum_{n=0}^\infty \frac{x^n}{n!}$$
$$xe^x = x \sum_{n=0}^\infty \frac{x^n}{n!} = \sum_{n=0}^\infty \frac{x^{n+1}}{n!}$$
So the first few terms of the Maclaurin series for $f(x)$ are:
$$f(x) = xe^x = x + x^2 + \frac{x^3}{2} + \frac{x^4}{3} + \frac{x^5}{24} + \cdots$$
To find the radius of convergence, we can use the ratio test:
$$\lim_{n\to\infty} \left| \frac{a_{n+1}}{a_n} \right| = \lim_{n\to\infty} \left| \frac{x^{n+2}/(n+1)!}{x^{n+1}/n!} \right| = \lim_{n\to\infty} \frac{|x|}{n+1} = 0$$
Since the limit is less than 1 for all values of $x$, the Maclaurin series converges for all values of $x$, and the radius of convergence is infinite.
What is the probability of a surveyed college student having a hard time falling asleep on 3 or more days in the last week
Answers
Answer:
Without more information about the specific survey and population being surveyed, it is difficult to provide a precise answer to this question. However, I can provide some general information on how probabilities can be calculated in surveys.
Assuming that the survey is a representative sample of college students and that the question about difficulty falling asleep is a binary (yes/no) question, we can calculate the probability of a surveyed college student having a hard time falling asleep on 3 or more days in the last week as follows:
1. Determine the total number of surveyed college students who answered the question about difficulty falling asleep.
2. Determine the number of surveyed college students who reported having a hard time falling asleep on 3 or more days in the last week.
3. Divide the number of surveyed college students who reported having a hard time falling asleep on 3 or more days in the last week by the total number of surveyed college students who answered the question about difficulty falling asleep.
For example, if 1,000 college students were surveyed and 800 of them answered the question about difficulty falling asleep, and 200 of those 800 reported having a hard time falling asleep on 3 or more days in the last week, then the probability of a surveyed college student having a hard time falling asleep on 3 or more days in the last week would be 200/800, or 0.25, or 25%.
If variance of the data a, b, c, ta, e is 2032 , then variance of 3a+2,3b+2, 3c+2,3d+2,3c+2, is :
Answers
The variance of 3a+2,3b+2, 3c+2,3d+2,3c+2, is 3657.6.
What is Variance?
Variance is a statistical measurement of the variation in numbers within a data set. Variance, in more precise terms, indicates how far apart any number in the set is from both the mean (average) and, consequently, from every other number in the set.
First, we can calculate the mean of the original dataset:
Mean = (a + b + c + ta + e) / 5
Then, we can calculate the variance using the formula:
Variance = ((a - Mean)² + (b - Mean)² + (c - Mean)² + (ta - Mean)² + (e - Mean)²) / 5
Given that the variance of the original dataset is 2032, we can substitute this value in the formula and solve for the mean:
2032 = ((a - Mean)² + (b - Mean)² + (c - Mean)² + (ta - Mean)² + (e - Mean)²) / 5
Simplifying this equation, we get:
(a - Mean)² + (b - Mean)² + (c - Mean)² + (ta - Mean)² + (e - Mean)² = 10160
Now, we can apply the transformation to the dataset by adding 2 and multiplying by 3:
New dataset: 3a + 2, 3b + 2, 3c + 2, 3d + 2, 3e + 2
To find the variance of the new dataset, we follow the same steps as before:
Mean = (3a + 2 + 3b + 2 + 3c + 2 + 3d + 2 + 3e + 2) / 5 = 3Mean + 2
Variance = ((3a + 2 - Mean)² + (3b + 2 - Mean)² + (3c + 2 - Mean)² + (3d + 2 - Mean)² + (3e + 2 - Mean)²) / 5
Simplifying this equation, we get:
Variance = ((3a - 3Mean)² + (3b - 3Mean)² + (3c - 3Mean)² + (3d - 3Mean)² + (3e - 3Mean)²) / 5
Variance = 9((a - Mean)² + (b - Mean)² + (c - Mean)² + (d - Mean)² + (e - Mean)²) / 5
Variance = 9(2032) / 5
Variance = 3657.6
Therefore, the variance of the new dataset is 3657.6.

Maricarmen le pide un préstamo de $24,000 a su amigo, el cuál le dice que cada mes debe pagarle un 20% del préstamo. ¿Qué cantidad del préstamo habrá pagado Maricarmen a los tres meses?
Answers
The amount repaid in the three months of the loan amount $24,000 with a condition of 20% repayment is equal to $11,712.
Percent of amount Maricarmen has to pay = 20% of the loan each month.
This implies Maricarmen pay 0.2 times the loan amount each month.
Amount Maricarmen will pay in the first month is equal to,
0.2 x $24,000 = $4,800
Amount left after the first payment,
$24,000 - $4,800 = $19,200
In the second month, Maricarmen will pay,
0.2 x $19,200 = $3,840
Amount left after the second payment,
$19,200 - $3,840 = $15,360
In the third month, Maricarmen will pay,
0.2 x $15,360 = $3,072
Amount left after the third payment,
$15,360 - $3,072 = $12,288
total amount paid in three months,
$4,800 + $3,840 + $3,072 = $11,712
Therefore, after three months Maricarmen will have repaid a total of $11,712 of the loan.

What is Synthetic division?Synthetic division is shortcut method used to divide polynomial by linear factor of form (x-a), where "a" is a constant. It is simplified method of polynomial long division, and it is especially useful when dividing by linear factor, as it avoids the need to write out all powers of x.
We list the factors of the leading coefficient 2 and the constant term 9:
Factors of 2: ±1, ±2
Factors of 9: ±1, ±3, ±9
Possible rational roots are: ±1, ±2, ±3, ±9
Using synthetic division with x = -1, we get:
-1 | 2 1 -12 9
-2 1 11
2 -1 -1 20
The remainder is not zero, so x = -1 is not a root of the equation.
Using synthetic division with x = -2, we get:
-2 | 2 1 -12 9
-4 6 -88
2 -3 -6 -79
The remainder is not zero, so x = -2 is not a root of the equation.
Using synthetic division with x = -3, we get:
-3 | 2 1 -12 9
-6 15 -9
2 -5 3 0
The remainder is zero, so x = -3 is a root of the equation. This means that (x + 3) is a factor of the equation.
Using polynomial long division, we get:
2x³ + x² - 12x + 9 = (x + 3)(2x² - 5x + 3)
quadratic factor can factored further we get:
2x² - 5x + 3 = (2x - 3)(x - 1)
Therefore, roots of given equation is:
x = -3 (root obtained earlier)
x = 3/2 (from 2x - 3 = 0)
x = 1(from x -1=0)
For the given equation 2x³ + x² - 12x + 9 = 0, the factors of the leading coefficient 2 are ±1, ±2, and the factors of the constant term 9 are ±1, ±3, ±9. Therefore, possible rational roots of equation are:
±1/1, ±3/1, ±1/2, ±3/2, ±9/2, ±1/9, ±3/9, ±9/9
Using synthetic division or other methods, we can check that the real rational roots of the equation are -3, 3/2, and 1.which we found in part (a).

6 A farmer has 2 400 sheep. He loses 32 and a half % due to the drought. After that he loses 15% due to sickness. How many sheep does he have now?
Answers
Answer: The farmer has 1377 sheeps.
Step-by-step explanation:
Farmer loses sheeps due to drought = 32½% of 2400
32½% of 2400
= 65 × 2400 × 1
2100
After cutting it will be,
65×12
=780
Number of sheeps that are left with him = 2400 - 780
=1620
After that,
The farmer loses due to sickness = 15% of 1620
15% of 1620
= 15 × 1620
100
After cutting it will be,
3 × 81
= 243
Total amount of sheeps that the farmer loses = 780 + 243
= 1023
Now the number of sheeps he has is 2400-1023
= 1377
Handy Automobiles produces two scooters: Basic and Discord. These scooters are produced by assembling multiple units of two key components C1 and C2. The component usage for the two scooters is given below:
Basic Discord
C1 6 10
C2 10 4
These components are produced within the plant. Marginal production costs for C1 and C2 are $8 and $12 respectively. The selling price of Discord is $500 and that of Basic is $400. The demand for these products are uncertain. Handy has to plan for the following 3 demand scenarios:
Basic Discord Prob
Scenario 1 600 200 30%
Scenario 2 400 400 40%
Scenario 3 300 500 30%
Due to the long lead times associated with production, Handy has to produce the components before they know which of the demand scenarios they need to plan for. However the components can be assembled to produce the two products after demand information is available. Unused components have no value and are discarded.
1. Develop a production plan for Handy
2. Suppose Handy can retool its production system and develop an additional component C3 which can serve as a substitute for both C1 and C2. However, the marginal cost of production of this component is $14. Should they go ahead with the retooling? If so, what is their new production plan?
Answers
Handy should produce 5400 units of C1 and 5600 units of C2 and the production plan should remain the same, with 5400 units of C1 and 5600 units of C2 being produced.
1. To develop a production plan for Handy, we need to calculate the expected demand for each component under each scenario. This is done by multiplying the demand for each scooter by the number of components used in its production, and then multiplying by the probability of each scenario occurring.
Expected demand for C1 = (600 x 6 x 0.3) + (400 x 6 x 0.4) + (300 x 6 x 0.3) + (200 x 10 x 0.3) + (400 x 10 x 0.4) + (500 x 10 x 0.3) = 5400
Expected demand for C2 = (600 x 10 x 0.3) + (400 x 10 x 0.4) + (300 x 10 x 0.3) + (200 x 4 x 0.3) + (400 x 4 x 0.4) + (500 x 4 x 0.3) = 5600
Therefore, Handy should produce 5400 units of C1 and 5600 units of C2.
2. To determine whether Handy should retool its production system to develop C3, we need to compare the expected cost of production with and without the new component.
Without C3:
Expected cost = (5400 x $8) + (5600 x $12) = $43,200 + $67,200 = $110,400
With C3:
Expected cost = (5400 x $14) + (5600 x $14) = $75,600 + $78,400 = $154,000
Since the expected cost of production with C3 is higher than without C3, Handy should not retool its production system to develop the new component. The production plan should remain the same, with 5400 units of C1 and 5600 units of C2 being produced.

Solve by Elimination:
5x+2y=−3
2x+3y=−10
Answers
Answer:
Multiplying the second equation by 2, we get:
4x + 6y = -20
Now we can subtract the first equation from this to eliminate x:
4x + 6y = -20
-(5x + 2y = -3)
-x + 4y = -17
Now we have one equation with only y. Solving for y:
-x + 4y = -17
4y = x - 17
y = (1/4)x - 17/4
Now we can substitute this expression for y into either equation to solve for x. Let's use the first equation:
5x + 2y = -3
5x + 2((1/4)x - 17/4) = -3
5x + (1/2)x - 17 = -3
(11/2)x = 14
x = 28/11
So the solution is (x,y) = (28/11, -17/11).

List three sides to a right triangle. Explain how you can use the Pythagorean theorem to know that your three sides will create a right triangle.
Answers
Answer: Three sides of a right triangle are the lengths of its legs and the length of its hypotenuse.
To know that three given sides will create a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. Symbolically, if a, b, and c are the lengths of the sides of a right triangle, with c being the hypotenuse, then:
c^2 = a^2 + b^2
Therefore, if we are given the lengths of three sides, we can square the lengths of the legs, add them together, and then take the square root to find the length of the hypotenuse. We can then compare the squared length of the hypotenuse to the sum of the squares of the legs. If they are equal, the three sides form a right triangle. If the squared length of the hypotenuse is greater than the sum of the squares of the legs, the three sides form an obtuse triangle. If the squared length of the hypotenuse is less than the sum of the squares of the legs, the three sides form an acute triangle.

A freight train left the main station heading east at average speed of 100kph. An hour later an express train left the same station heading west at an average of 170kph. At what time will they be 600kms apart from each other?
Answers
Apart from each other 3.33 hours
To determine at what time the freight and express trains will be 600 km apart from each other, we must first determine the distance covered by each train. We can then use these distances to determine the total distance between the two trains at any given time.In this problem, we are given the following information:A freight train leaves the main station heading east at an average speed of 100 km/h.An hour later, an express train leaves the same station heading west at an average speed of 170 km/h.We are asked to determine the time at which they will be 600 km apart from each other.We can use the following formula to determine the distance covered by each train:D = RTwhere:D is the distance coveredR is the average speedT is the time takenTo find the distance covered by the freight train, we can use the following formula:D1 = RT1where:D1 is the distance covered by the freight trainR is the average speed of the freight trainT1 is the time taken by the freight trainTo find the distance covered by the express train, we can use the following formula:D2 = RT2where:D2 is the distance covered by the express trainR is the average speed of the express trainT2 is the time taken by the express trainNow, let's determine the distances covered by each train:D1 = 100(T1+1)D2 = 170T2We know that the total distance between the two trains is 600 km, so we can use the following equation to solve for the time at which they will be 600 km apart:D1 + D2 = 600100(T1+1) + 170T2 = 600100T1 + 170T2 + 100 = 600100T1 + 170T2 = 500(100/170)T1 + T2 = 5.9 hoursThe time taken by the freight train is T1 + 1, so we can substitute T1 + 1 for T1 in the equation above to solve for T1:T1 + T2 = 5.9100(T1+1)/170 + T2 = 5.9T1 + 1 + 1.7T2 = 5.9T1 + 1.7T2 = 4.9T1 = (4.9 - 1.7T2)/1.9Now, we can substitute this value of T1 into the equation we used earlier to solve for T2:100T1 + 170T2 = 500100((4.9 - 1.7T2)/1.9) + 170T2 = 500T2 ≈ 2.33Therefore, the time at which the two trains will be 600 km apart from each other is approximately 2.33 hours after the express train leaves the main station. To find the exact time, we need to add this value to the time at which the express train left the main station:Time = 1 + 2.33 = 3.33 hoursTherefore, the two trains will be 600 km apart from each other 3.33 hours after the express train leaves the main station.
