Approximately 15.87% of the bowlers in the Capital Three bowling tournament performed better than Dr. Baker.

Standard deviation (σ) = √(variance) = √(121) = 11

Now, we can calculate the z-score for Dr. Baker's average of 169 using the formula:

z = (X - μ) / σ

z = (169 - 158) / 11

z = 11 / 11

z = 1

Dr. Baker's z-score is 1, meaning his performance is one standard deviation above the mean.

The area to the left (or the cumulative probability) is approximately 0.8413

1 - 0.8413 = 0.1587

Therefore , the solution of the given problem of probability comes out to be  z-score from a typical normal distribution.

Any considerations technique's fundamental objective is to determine the likelihood that a claim is true or that a particular incident will take place. Any number range from one to one, when 0 traditionally signifies a percentage and 1 typically implies the degree of certainty, can be used to represent chance. A probability illustration shows the likelihood that a particular event will occur.

Here,

The formula for the standard error of the mean (SEM), which is as follows:

=> SEM = the standard deviation / √(sample size).

We can enter these numbers into the SEM calculation to determine the SEM given that the standard deviation of the tariff rates is $1200 and the sample size is 400:

=> SEM=$1200/√(400)

=> $1200/20 =$60

It is possible to calculate the z-score for a $80 departure from the mean with a $60 SEM as follows:

=>  z = (80 - 0) / $60 = 1.3333

Now that we have the probability corresponding to the z-score of 1.3333,

we can look up the cumulative distribution function (CDF) of the standard normal distribution using a z-table or a statistical calculator.

If we borrowed amount of $400 for 5 weeks, then the APR at which the money is borrowed is 260.71%.

First, we calculate the total interest paid for borrowing $400 for five weeks.

The interest rate is $25 per $100 borrowed, so for $400 borrowed, the interest paid is : $25 × 4 = $100,

So, the total amount that needs to be paid-back is $400 (the original borrowed amount) plus $100 (the interest paid) = $500,

Next, we can use the APR formula to calculate, which is

⇒ APR = (Interest Paid/Amount Borrowed)/(Number of days) × 365 × 100,

In this case, the total interest paid is $100 and the total amount borrowed is $400, and

The number of days amount is borrowed is = 5×7 = 35 days,

Substituting the values,

We get,

⇒ APR = (100/400)/35 ×365 × 100 ≈ 260.71%

Therefore, the APR at which the money is being borrowed is 260.71%.

Step-by-step explanation:

first of all, remember, the sum of all angles in a triangle is always 180°.

now, we see that both bottom angles are 45°.

that means

180 = 45 + 45 + top-angle

90° = top-angle

aha ! we are dealing with a right-angled triangle, that is also isoceles (both legs are equally long, because the angles with the baseline are equal).

via Pythagoras

c² = a² + b²

where "c" is the Hypotenuse (the side opposite of the 90° angle), "a" and "b" are the legs.

in our case both legs are 7×sqrt(2) units long.

so,

baseline² = (7×sqrt(2))² + (7×sqrt(2))² = 49×2 + 49×2 =

= 98 + 98 = 196

baseline = sqrt(196) = 14 units

x is now the height of this triangle, and because of the isoceles form, it splits the baseline exactly in half.

so, one side of the baseline from x is 14/2 = 7 units.

and now Pythagoras for that sub-triangle :

(7×sqrt(2))² = 7² + x²

98 = 49 + x²

49 = x²

x = sqrt(49) = 7 units

the area of the triangle is

baseline × height / 2

in our case

14 × 7 / 2 = 7×7 = 49 units²

Answer:

55.8° (nearest tenth)

Step-by-step explanation:

The angle of depression is the angle between the horizontal line of sight at the top of the treehouse and line of sight to the sandbox (the flight path of the paper airplane). (See attached diagram).

To find the angle of depression, we can use the cosine trigonometric ratio. The cosine of an angle is equal to the ratio of the length of the side adjacent the angle to the length of the hypotenuse.

[tex]\boxed{\begin{minipage}{9 cm}\underline{Cosine trigonometric ratio} \\\\$\sf \cos(\theta)=\dfrac{A}{H}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]

In this case, the length of the side adjacent the angle of depression is equal to the distance between the base of the tree and the sandbox, so A = 9 ft. The hypotenuse is the distance the airplane flies through the air, so H = 16 ft.

Substitute these values into the cosine ratio and solve for θ:

[tex]\cos (\theta)=\dfrac{9}{16}[/tex]

[tex]\theta=\cos^{-1}\left(\dfrac{9}{16}\right)[/tex]

[tex]\theta=55.7711336...^{\circ}[/tex]

Therefore, the angle of depression that the paper airplane is flying down at is 55.8° (nearest tenth).

To calculate the locator and percentile, we need to first arrange the scores in ascending order:

6, 8, 11, 12, 14, 17, 20, 34, 36, 38, 47, 48, 49

a) To calculate the locator for the 52nd percentile, we use the following formula:

Lp = (p/100) * (N + 1)

where Lp is the locator for the pth percentile, p is the percentile we are interested in, and N is the total number of scores.

For the 52nd percentile, p = 52 and N = 13. Substituting these values into the formula, we get:

L52 = (52/100) * (13 + 1) = 6.72

Therefore, the locator for the 52nd percentile is 6.72.

b) To determine the 52nd percentile, we need to find the score corresponding to the locator L52. Looking at the ordered list of scores, we see that the score at position 6 is 17 and the score at position 7 is 20. Since the locator L52 falls between positions 6 and 7, we can use linear interpolation to estimate the 52nd percentile:

P52 = (7 - L52) / (7 - 6) * 50 + (L52 - 6) / (7 - 6) * 50

P52 = (7 - 6.72) / (7 - 6) * 50 + (6.72 - 6) / (7 - 6) * 50

P52 = 38 + 0.48 * 50

P52 = 61.4

Therefore, the 52nd percentile is approximately 61.4.

c) To find the percentage of scores that are above the 52nd percentile, we subtract the 52nd percentile from 100:

100 - 52 = 48

Therefore, approximately 48% of the scores in the dataset are above the 52nd percentile.

Answer: 601 meters

Step-by-step explanation:

First, let's find the midpoint between the "Falcon Flyer" and the "Sprinter".

The x-coordinate of the midpoint is (50 + 400)/2 = 225.

The y-coordinate of the midpoint is (300 + 550)/2 = 425.

So the midpoint is (225, 425).

Now we need to find the distance between the midpoint and the "Air Rider". Using the distance formula:

d = sqrt[(800 - 225)^2 + (250 - 425)^2]

d = sqrt[(575)^2 + (-175)^2]

d = sqrt[330625 + 30625]

d = sqrt(361250)

d ≈ 601.041

1. the APR for this loan is 6%.

2.  the unearned interest is $118.83.

3.  the monthly payment necessary to amortize the $80,000 mortgage at 6% annual interest for 25 years is $506.69.

APR = (finance charge / loan amount) / number of years * 100%

In this scenario, the loan amount is $2400 and the finance charge is $288. Since it's a two-year loan, the number of years is 2

APR = (288 / 2400) / 2 * 100%

APR = 0.06 * 100%

APR = 6%

b.

Number of payments = 4 years * 12 months/year = 48

If the loan is paid off in 3 years instead of 4 years, the number of payments made is:

Number of payments made = 3 years * 12 months/year = 36

Substituting these values into the formula, we get:

Unearned interest = (1426 / 48) * (48 - 36)

Unearned interest = $118.83

3.

To find the monthly payment necessary to amortize a mortgage, we need to use the formula:

M = P * (r / (1 - (1 + r)^(-n)))

where M is the monthly payment, P is the principal (loan amount), r is the monthly interest rate, and n is the total number of payments (in months).

In this scenario, the loan amount is $80,000, the annual interest rate is 6%, and the loan term is 25 years. To find the monthly interest rate, we divide the annual interest rate by 12 (since there are 12 months in a year):

Monthly interest rate = 6% / 12 = 0.005

To find the total number of payments, we multiply the number of years by 12:

Number of payments = 25 years * 12 months/year = 300

Substituting these values into the formula, we get:

M = 80000 * (0.005 / (1 - (1 + 0.005)^(-300)))

There are 32 quarters, 225 dimes, and 53 nickels in the vending machine.

Let's denote the number of nickels by N, the number of dimes by D, and the number of quarters by Q.

From the first sentence, we know that:

N + D + Q = 292 (total number of coins)

From the second sentence, we know that:

D = 3(N + Q) (the number of dimes is three times the number of nickels and quarters together)

From the third sentence, we know that:

0.05N + 0.1D + 0.25Q = 29.95 (total value of the coins is $29.95)

Now we can substitute the second equation into the third equation to get:

0.05N + 0.1(3(N + Q)) + 0.25Q = 29.95

0.05N + 0.3N + 0.1Q + 0.25Q = 29.95

0.35N + 0.35Q = 29.95

N + Q = 85

We can now substitute this last equation into the first equation to get:

N + D + Q = 292

N + D + 85 = 292

N + D = 207

We can substitute the second equation into this last equation to get:

N + 3(N + Q) = 207

4N + 3Q = 207

We can now solve the system of equations consisting of the last two equations we derived:

N + Q = 85

4N + 3Q = 207

Multiplying the first equation by 4 and subtracting it from the second equation:

4N + 3Q - 4(N + Q) = 207 - 4*85

-N = -53

N = 53

Substituting this value into the equation N + Q = 85:

53 + Q = 85

Q = 32

Finally, we can use the equation D = 3(N + Q) from earlier to find the value of D:

D = 3(N + Q)

D = 3(53 + 32)

D = 225

How to solve the question?

To determine whether the fitness program has had a significant effect on reducing employee absenteeism, we need to conduct a hypothesis test.

Null hypothesis: The average number of absences before and after the fitness program are the same.

Alternative hypothesis: The average number of absences after the fitness program is less than before the program.

To test this hypothesis, we can use a one-tailed paired t-test with a significance level of 0.05. We will calculate the difference between the number of absences before and after the program for each employee, and then compute the mean and standard deviation of the differences. The t-test statistic will then be calculated as the mean difference divided by the standard deviation of the differences, multiplied by the square root of the sample size.

Using the given data, we calculate the differences and obtain the following results:

Employee Before After Difference (d) d²

1 8 7 -1 1

2 7 3 -4 16

3 8 2 -6 36

4 8 4 -4 16

5 6 5 -1 1

6 7 10 3 9

7 6 4 -2 4

8 8 9 1 1

Mean difference (d-bar) = -1.25

Standard deviation of differences (s) = 3.27

Sample size (n) = 8

The t-test statistic can now be calculated as:

t = (d-bar / (s / √(n))) = (-1.25 / (3.27 / √(8))) = -1.63

The degrees of freedom for the t-test is n-1 = 7, which can be used to obtain the p-value from a t-table or calculator. Using a one-tailed test with a significance level of 0.05 and 7 degrees of freedom, the critical t-value is -1.895.

Since our calculated t-value (-1.63) is greater than the critical t-value (-1.895), we fail to reject the null hypothesis. In other words, we do not have sufficient evidence to conclude that the fitness program has resulted in a significant reduction in employee absenteeism.

The p-value can also be calculated using a t-distribution table or a statistical software package. Using a two-tailed test with 7 degrees of freedom and a significance level of 0.05, we obtain a p-value of 0.073. Since this p-value is greater than the significance level, we again fail to reject the null hypothesis.
