The normal distribution has a bell-shaped curve, with the highest point at the mean and a gradual decrease in frequency on either side.
What is Normal Distribution ?
A normal distribution is a continuous probability distribution that is often used in statistics to model a wide variety of phenomena, such as measurements of height, weight, or IQ.
The normal distribution is symmetric. This means that the distribution is mirror-image symmetric around its mean, so that the same proportion of values lie on either side of the mean.
The normal distribution is characterized by two parameters: its mean (μ) and standard deviation (σ). The mean is the center of the distribution, while the standard deviation measures the spread of the distribution.
The total area under the normal distribution curve is equal to 1. This means that the probability of any event occurring is between 0 and 1.
The empirical rule, also known as the 68-95-99.7 rule, applies to normal distributions. This rule states that approximately 68% of the data will fall within one standard deviation of the mean, approximately 95% of the data will fall within two standard deviations of the mean, and approximately 99.7% of the data will fall within three standard deviations of the mean.
Therefore, The normal distribution has a bell-shaped curve, with the highest point at the mean and a gradual decrease in frequency on either side.

In a science experiment the temperature of a liquid is first read at 11.15am. If the temperature is read every 12 hours, at what time will the eight temperature reading be taken?
If the temperature is read every 12 hours, then the eighth temperature reading will be taken at 11.15 pm three days after the first reading.
What is temperature?Temperature is a measure of the degree of hotness or coldness of a substance or object, typically measured using a thermometer in degrees Celsius or Fahrenheit.
If the temperature is read every 12 hours, then the time interval between two consecutive temperature readings is 12 hours.
To find the time of the eighth temperature reading, we need to add 12 hours for each of the previous seven temperature readings:
First reading: 11.15 am
Second reading: 11.15 am + 12 hours = 11.15 pm
Third reading: 11.15 pm + 12 hours = 11.15 am (next day)
Fourth reading: 11.15 am (next day) + 12 hours = 11.15 pm (next day)
Fifth reading: 11.15 pm (next day) + 12 hours = 11.15 am (two days after the first reading)
Sixth reading: 11.15 am (two days after the first reading) + 12 hours = 11.15 pm (two days after the first reading)
Seventh reading: 11.15 pm (two days after the first reading) + 12 hours = 11.15 am (three days after the first reading)
Eighth reading: 11.15 am (three days after the first reading) + 12 hours =
11.15 pm (three days after the first reading)

The graph of f ( x ) = − 1 /2 ( 1 /2 ) ^x − 3 + 5 is shifted downwards 5 units, and then shifted left 3 units, stretched vertically by a factor of 4 , and then reflected about the x -axis. a . What is the equation of the new function, g ( x ) ? g ( x ) = b . What is the y -intercept? ( , ) c . What is the domain? d . What is the range?
Answer: a. To shift the graph of f(x) downward 5 units, we subtract 5 from the function: f(x) - 5. To shift it left 3 units, we replace x with x + 3: f(x + 3) - 5. To stretch it vertically by a factor of 4, we multiply the entire function by 4: 4[f(x + 3) - 5]. Finally, to reflect it about the x-axis, we take the negative of the function: -4[f(x + 3) - 5]. Therefore, the equation of the new function g(x) is:
g(x) = -4[1/2^(x+3) - 5]
b. To find the y-intercept, we set x = 0 in the equation of g(x):
g(0) = -4[1/2^(0+3) - 5] = -4[1/8 - 5] = -4[-39/8] = 195/2
Therefore, the y-intercept is (0, 195/2).
c. The domain of g(x) is all real numbers, since there are no restrictions on x.
d. To find the range of g(x), we first observe that the function is decreasing and asymptotic to y = -5 as x approaches infinity. This means that the range of g(x) is all real numbers less than or equal to -5.

15. The equation of a circle is x² + y2 = 64. A point on the circle has coordinates (x. √28). Determine the possible
values of x. You must show work to receive credit.
Answer:
±6
Step-by-step explanation:
To find the possible values of x for a point on the circle with equation x² + y² = 64, we can substitute the given y-coordinate of √28 into the equation and solve for x:
x² + (√28)² = 64
x² + 28 = 64
x² = 64 - 28
x² = 36
Taking the square root of both sides, we get:
x = ±6
Therefore, the possible values of x for a point on the circle with coordinates (x, √28) are x = 6 and x = -6.

a. What is the probability that you choose an N?
b. What is the probability that you choose an A?
c. What is the probability that you choose an E?
Answer:
A maybe
Step-by-step explanation: sorry if wrong
a. There are three N's in PENNSYLVANIA. The probability of choosing an N can be calculated as follows:
Probability of choosing an N = (Number of N's in the word) / (Total number of letters in the word)
Probability of choosing an N = 3 / 12
Probability of choosing an N = 1 / 4
Therefore, the probability of choosing an N is 1/4.
b. There are two A's in PENNSYLVANIA. The probability of choosing an A can be calculated as follows:
Probability of choosing an A = (Number of A's in the word) / (Total number of letters in the word)
Probability of choosing an A = 2 / 12
Probability of choosing an A = 1 / 6
Therefore, the probability of choosing an A is 1/6.
c. There is only one E in PENNSYLVANIA. The probability of choosing an E can be calculated as follows:
Probability of choosing an E = (Number of E's in the word) / (Total number of letters in the word)
Probability of choosing an E = 1 / 12
Therefore, the probability of choosing an E is 1/12.

Given f(x) = 2x2 + 9x − 1 and g(x) = −x − 4, identify g(f(−3)).
Answer:
g(f(-3)) = 6.
Step-by-step explanation:
To obtain the value of f(-3), we must first determine g(f(-3)), which requires changing x in the expression for f(x) to -3:
f(x) = 2x^2 + 9x - 1
f(-3) = 2(-3)^2 + 9(-3) (-3) - 1\s= 2(9) (9) - 27 - 1\s= 18 - 27 - 1\s= -10
Knowing that f(-3) = -10 allows us to replace it in the expression for g(x):
g(x) = -x - 4
g(f(-3)) = g(-10) (-10)
Now, if we replace x in g(x) with -10, we obtain:
g(f(-3)) = g(-10) = -(-10) (-10) - 4 = 10 - 4 = 6
Hence, g(f(-3)) = 6.
Answer:
g(f(-3))=6
Step-by-step explanation:
To calculate g(f(-3)), we must first determine the value of f(-3), and then we must insert that value into g(x) to obtain the result.
By adding x = -3 to the formula for f(x), we may obtain f(-3).
f(-3) = 2(-3)
² + 9(-3) - 1
f(-3) = 2(9) - 27 - 1
f(-3) = 18 - 28
f(-3) = -10
Knowing that f(-3) = -10 allows us to replace it in the formula for g(x):
g(f(-3)) = g(-10) = -(-10) (-10) - 4 = 10 - 4 = 6
Hence, g(f(-3)) = 6.
Without using tables Find the value of 0.45*0.91÷0.0117
the value of 0.45 × 0.91 ÷ 0.0117 is 35.
Why it is and what is PEMDAS?
To find the value of 0.45 * 0.91 ÷ 0.0117, we can use the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
First, we need to perform the multiplication of 0.45 and 0.91:
0.45 ×0.91 = 0.4095
Then, we need to divide the result by 0.0117:
0.4095 ÷ 0.0117 = 35
Therefore, the value of 0.45 * 0.91 ÷ 0.0117 is 35.
PEMDAS is a mnemonic used to remember the order of operations in arithmetic and algebraic expressions. It stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction.
The order of operations is as follows:
Parentheses: Perform operations within parentheses first, working from the innermost set of parentheses to the outermost.
Exponents: Perform any calculations involving exponents, such as raising a number to a power or taking the square root.
Multiplication and Division: Perform multiplication and division in the order that they appear from left to right.

What is the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5
Answer:
the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5 is 257/30 = 8 and 39/40.
Step-by-step explanation:
To find the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5, we need to first add the two summands:
4 and 2/3 + 5 and 2/5
To add these mixed numbers, we first need to find a common denominator. The least common multiple of 3 and 5 is 15.
4 and 2/3 can be written as an improper fraction with denominator 3:
4 and 2/3 = 4 x 3/3 + 2/3 = 12/3 + 2/3 = 14/3
5 and 2/5 can be written as an improper fraction with denominator 5:
5 and 2/5 = 5 x 5/5 + 2/5 = 25/5 + 2/5 = 27/5
Now we can add the two fractions with a common denominator of 15:
14/3 + 27/5 = (14 x 5)/(3 x 5) + (27 x 3)/(5 x 3) = 70/15 + 81/15 = 151/15
So, the sum of 4 and 2/3 and 5 and 2/5 is 151/15.
Now we can subtract 1 and 1/2 from this sum:
151/15 - 1 1/2
To subtract mixed numbers, we first need to convert 1 and 1/2 to an improper fraction:
1 and 1/2 = 1 x 2/2 + 1/2 = 2/2 + 1/2 = 3/2
Now we can subtract the fractions with a common denominator of 15:
151/15 - 3/2 = (151 x 2)/(15 x 2) - (3 x 15)/(2 x 15) = 302/30 - 45/30 = 257/30
Therefore, the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5 is 257/30.

What is a Quadratic equation?
A polynomial equation of the second degree, or a quadratic, must contain at least one squared term to be considered a quadratic. Equations using quadratics is another name for it. The quadratic equation has the following general form: ax2 + bx + c = 0, where x is an unknown variable and a, b, and c are numerical coefficients. A quadratic equation is one like x2 + 2x + 1 for instance.
Given equation:
4r² + 3r + 15 = 9
we can simplify it as :
4r² + 3r = 9 - 15
4r² + 3r = - 6
4r² + 3r + 6 = 0
Now, we will use Quadratic formula which is given by :
r = [ -b + √b² - 4ac ] / 2a
Substituting values as a = 4, b = 3 and 6.
we get,
r = [ -3 + √3² - 4(4)(6) ] / 2(4)
= [ -3 + √(-87)]/8
since, its determinant (b² -4ac) is negative, hence the given equation has no roots.

Two vessels are pulling a broken-down ship toward a boathouse with forces of 750lb and 630lb. The angle between the forces is 34.5°. Determine the magnitude of the equilibrant force.
The magnitude of the equilibrant force is 938.893 lb
How to find the equilibrant forceWe can use the concept of vector addition to solve this problem. The equilibrant force is the force that is needed to balance out the two given forces, so that the net force on the broken-down ship is zero.
Let's represent the two given forces as vectors A and B, with magnitudes of 750 lb and 630 lb, respectively. The angle between them is 34.5 degrees.
|C|^2 = |A|^2 + |B|^2 - 2|A||B|cosθ
where
θ is the angle between the two forces.
Substituting the given values, we get:
|C|^2 = (750 lb)^2 + (630 lb)^2 - 2(750 lb)(630 lb)cos(34.5°)
Simplifying this expression, we get:
|C|^2 = 562500 + 396900 - 945000 * cos(34.5°)
|C|^2 = 881520.0752
Taking the square root of both sides, we get:
|C| ≈ 938.893 lb

what is decimal?The decimal number system is frequently used to express both integer and non-integer quantities. Non-integer values have been added to the Hindu-Arabic numeral system. The technique used to represent numbers in the decimal system is known as decimal notation. A decimal number consists of both a whole number and a fractional number. The numerical value of complete and partially whole quantities is expressed using decimal numbers, which are in between integers. The full number and the fractional part of a decimal number are separated by a decimal point. The decimal point is the little dot that appears between whole numbers and fractions. An example of a decimal number is 25.5.
We must separate the whole number and fraction components of 2.655 in order to change it into a mixed number. The integer portion of the decimal, which is 2 in this instance, represents the full number.
We take the total number and divide it by the decimal to determine the fractional portion.
2.655 - 2 = 0.655
The combined number is therefore 2 and 655/1000.
By dividing the numerator and denominator by their largest common factor, we may reduce the fraction to its simplest form and so make it easier to understand. The highest common factor between 655 and 1000 in this instance is 5.
655 ÷ 5 = 131
1000 ÷ 5 = 200
Hence, 2 131/200 is the mixed number in its most basic form.

describe how a graph would look for the solution set for the inequality in problem 5. describe what the solution means and how the price of the balloons bought will affect the amount in the budget.
A)
i) the inequality to show the number of ballons that the dance committee can buy is: 0.80b + 65 ≤ 125
ii) solving the inequality above, we arrive at b ≤ 75
B) The graph is attached accordingly.
C) See the description of the solution below.
Let's start by defining our variables. Let b be the number of balloons that the dance committee could buy.
The cost of b balloons is $0.80b. We want to make sure that the cost of the balloons plus the amount already spent on decorations ($65) is less than or equal to the budget of $125. So we can write the following inequality:
0.80b + 65 ≤ 125
Now we can solve for b:
0.80b + 65 ≤ 125
0.80b ≤ 125 - 65
0.80b ≤ 60
b ≤ 75
Therefore, the dance committee can buy up to 75 balloons to stay within their budget.
To graph the solution set, we can plot b on the horizontal axis and shade the region to the left of b = 75, since b must be less than or equal to 75.
The solution set represents all possible values of b that satisfy the inequality. In this case, the solution set is b ≤ 75, which means that the dance committee can buy up to 75 balloons and still stay within their budget.
As the number of balloons increases, the cost of the balloons also increases, and the amount of money left in the budget decreases.
Therefore, the more balloons the dance committee buys, the less money they will have left for other decorations or expenses.

Randy and Corey are discussing a lesson they learned in Math. Randy says that "All trapezoids are parallelograms." Corey disagrees. Who do you think is correct, Randy or Corey? Explain why you think Randy or Corey is correct.
Cory's statement is correct. A Trapezoid cannot be Parallelogram.
What is Trapezium?A trapezium is a polygon with a single pair of parallel sides. Trapezoid parallel bases are another name for these parallel sides. The other two non-parallel sides are known as trapezoidal legs.
A parallelogram is a quadrilateral having two pairs of parallel sides. The length and size of a parallelogram's opposed sides and opposite angles are equal. Its inner angles add up to 360°.
According to the given information:
Randy's claim is that "all trapezoids are parallelograms." Nonetheless, Cory disagrees with the statement "A Trapezoid is not a Parallelogram."
Corey's assertion is correct.
Because a trapezium is a quadrilateral with exactly one set of parallel opposed sides.
A parallelogram is a quadrilateral having opposite pairs of sides that are parallel.
The trapezoid does not satisfy the parallelogram criterion. As a result, a trapezium cannot be a parallelogram.

A deli has two platters of sandwiches. The first platter costs $29 and you get 2 ham sandwiches and 3 turkey sandwiches. The other platter costs $31 and you get 3 ham sandwiches and 2 turkey sandwiches. Let x represent the cost of each ham sandwich and y represent the cost of each turkey sandwich. What is the system of linear equations for the given scenario? What is the cost of each sandwich?
Solution is in da attachment mate!! :D
Step-by-step explanation:
that is a college question ?
x = cost of a ham sandwich
y = cost of a turkey sandwich
2x + 3y = 29
3x + 2y = 31
let's multiply the first equation by 3, abd the second equating by -2, and then we add them :
6x + 9y = 87
-6x - 4y = -62
------------------------
0 5y = 25
y = 25/5 = $5
let's use the original first equation to get x (but we could use also the second equation, it does not matter).
2x + 3×5 = 29
2x + 15 = 29
2x = 14
x = $7
each ham sandwich costs $7.
each turkey sandwich costs $5.
