PLEASE QUICK!

Answers

Answer 1

c) Shane’s overall average number of jumps completed is of 2.458275.

d) As Shane's overall average number is greater than one half, then the eight graders will be awarded the 50 points.

How to obtain the average number of jumps completed?

The jumps that Shane takes are given as follows:

Lowest bar: 100% probability of completed, as 3/3 = 100.Middle bar: 0.8333 = 83.33% probability, as 5/6 = 0.8333.Highest bar: 0.75 = 75% probability, as 3/4 = 0.75.

Then the probabilities for each number are given as follows:

One jump -> only the lowest: 1 x (1 - 0.8333) = 0.1667.Two jumps -> lowest and middle: 1 x 0.8333 x (1 - 0.75) = 0.208325.Three jumps -> all -> 1 x 0.8333 x 0.75 = 0.624975.

Then the distribution of the number of jumps completed is given as follows:

P(X = 1) = 0.1667.P(X = 2) = 0.208325.P(X = 3) = 0.624975.

The expected value of a discrete distribution is calculated as the sum of each outcome multiplied by it's respective probability, hence:

E(X) = 1 x 0.1667 + 2 x 0.208325 + 3 x 0.624975 = 2.458275.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Gross pay = $2759

Deduction:

7.65%

= 7.65/100 x 2759

= $211.06

12%

= 12/100 x 2759

= $331.08

7%

= 7/100 x 2759

= $193.13

The remaining amount.

= 2759 - 211.06 - 331.08 - 193.13

In this case, the coefficient of determination is 0.5297, which means that 53% of the sample variation in Final grades is explained by the sample regression equation.

The data file contains the midterm and final scores of 32 students in a statistics course. To estimate a student's final score as a function of their midterm score, we used a regression analysis. The regression equation was Final = 27.5818 + 0.6774 Midterm. This equation can be used to predict the final score of a student based on their midterm score. The standard error of the estimate was 14.947. This indicates the accuracy of the estimated final score. The coefficient of determination was 0.5297, which means that 53% of the sample variation in final grades is explained by the regression equation. This tells us that the regression equation is a relatively good predictor of a student's final score.

Given:

Midterm Score = x

Final Score = y

Regression Equation: y = 27.5818 + 0.6774x

Standard Error of the Estimate = 14.947

Coefficient of Determination = 0.5297

Calculating Final Score:

y = 27.5818 + 0.6774x

y = 27.5818 + 0.6774(x)

y = 27.5818 + 0.6774(x)

y = 27.5818 + 0.6774(x)

s/180 = n -2

Add 2 both the side of the equation we get,

Answers

Answer:

The exact value of x so that the greatest possible amount of light is emitted is 8.96ft.

What is the perimeter of a semicircle?

The perimeter of a semicircle is half that of a circle, that is [tex]\pi r[/tex], where r is the radius of the circle.

Step-by-step explanation:

Given the width of the rectangle is x, let the height of the rectangle be y.

The radius of the semicircle is x/2.

The perimeter of the window is equal to [tex]2y+x+\pi \frac{x}{2} =32[/tex].

The area of the window is [tex]xy+\frac{1}{2}(\pi )(\frac{x}{2})^2=xy+\frac{\pi x^2}{8}[/tex].

We can insert into the formula for the area to obtain the area in terms of only x by solving the equation for the perimeter of y in terms of x.

[tex]2y=32-(1+\frac{\pi }{2} )x=32-(\frac{2+\pi }{2} )x\\y=16-(\frac{2+\pi }{4} )x[/tex].

Now the area of the window in terms of only x is:

Area=[tex]16x-(\frac{2+\pi }{4} )x^2+\frac{\pi x^2}{8}[/tex].

Since it is given in the question that maximum light should be admiitted, we will differentiate the Area and set it to 0.

[tex]16-2(\frac{2+\pi }{4} )x+\frac{\pi x}{4}=0\\ 16=x(1+\frac{\pi }{4})\\ x=\frac{16}{1+\frac{\pi }{4}} \\x=8.96ft[/tex].

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be ABC

29 / 14.5 = x / 15.5

On simplifying the equation , we get

x/15.5 = 2

Multiply by 15.5 on both sides of the equation , we get

x = 2 x 15.5

x = 31

Therefore , the value of x is 31

Hence , the value of x of side YZ is 31

Which set of ordered pairs represents a function? {(-1, 3), (2, 6), (3, 9), (4, 12), (5, 20)} {(-7, 3), (-7, 6), (-7, 12), (-7, 18)} {(9, -3), (4, -2), (1, -1), (0, 0), (1, -3)}

Answers

From the given pairs of ordered pairs {(-1, 3), (2, 6), (3, 9), (4, 12), (5, 20)} it is a function.

What is a Function?

The core concept of mathematics calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x.

As per the set of ordered pairs given in the question,

1.

{(-1, 3), (2, 6), (3, 9), (4, 12), (5, 20)}

It is a function because every input has a single output.

2.

{(-7, 3), (-7, 6), (-7, 12), (-7, 18)}

It is not a function because 7 corresponds to two different images like 3, 6, 12, and 18.

3.

{(9, -3), (4, -2), (1, -1), (0, 0), (1, -3)}

It is not a function because 1 corresponds to two different images, like -1 and 3.

Suppose that the population of a certain town is made of 45% men and 55% women. Of the men, 40% wear glasses, and of the women 20% wear glasses. Given that a person chosen at random from this town wears glasses, what is the probability that the person is a woman?

Answers

The probability that the person is a woman is 40%.

what is the probability that the person is a woman?P(woman | glasses) = (20% * 55%) / (40% * 45% + 20% * 55%) = 0.55There is a 50% probability that a sperm will fertilize a boy and a 50% chance that a sperm will fertilize a female ovum each time.The probability that a randomly chosen person in this town wears glasses is equal to the sum of the probability of a man wearing glasses and the probability of a woman wearing glasses.

P(Glasses) = P(M ∩ G) + P(W ∩ G)

P(Glasses) = 0.45 × 0.40 + 0.55 × 0.20

P(Glasses) = 0.27

The probability that the randomly chosen person is a woman is equal to the probability of a woman wearing glasses divided by the probability of a person wearing glasses.

P(Woman) = P(W ∩ G) / P(Glasses)

P(Woman) = 0.55 × 0.20 / 0.27

P(Woman) = 0.44

Find the length and width of a rectangle that has the given area and a minimum perimeter.
Area: 5A square cm
Find length and width of a rectangle with minimum perimeter that has an area of 5A square cm
length=
width=

Answers

By taking minimum perimeter the value of length and width will both be [tex]\sqrt{5A}[/tex].

What is perimeter?

Perimeter is basically the sum of all sides of a figure.

How to calculate perimeter of rectangle?

The perimeter of a rectangle is 2l + 2w where l = length and w = width of rectangle.

Since the perimeter needed in this question is minimum, the figure must be a square and not a rectangle. For a square, area = a^2

5A = a^2

a = l = w = [tex]\sqrt{5A}[/tex]

Hence, both the length and width are equal to [tex]\sqrt{5A}[/tex].
