The length of the other leg is 9 units. Therefore, option B is the correct answer.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

Given that, one leg of a right triangle is 8 units long, and its hypotenuse is 12 units long.

Let the length of the other leg be x.

12²=8²+x²

144=64+x²

x²=144-64

x²=80

x=√80

x=8.94

x≈9 units

Therefore, option B is the correct answer.

After solving, the test statistic value of z is -2.65.

In the given question,

Sample Mean x=264.4

Population standard deviation σ=20

sample size (n) = 25

significance level α=0.05

To test  Jean's claim that Jack's driving distance is less than 275 yards

The null and alternative hypothesis are

H(0): μ=275

H(α): μ<275

Test Statistic Z is:

Z = (x-μ)/(σ/√n)

Z = (264.4-275)/(20/√25)

Z = -10.6/(20/5)

Z = -10.6/4

Z = -2.65

Hence, the test statistic value of z is -2.65.

The right question is:

Jack tells Jean that his average drive of a golf ball is 275 yards. Jean is skeptical, she thinks he has overstated is driving distance and asks for substantiation. So Jack takes a random sample of 25 of his drives. The mean of this sample is 264.4 yards. His driving distance is known to be normally distributed with a population standard deviation of 20 yards. Test Jean's claim that Jack's driving distance is less than 275 yards at a 0.05 significance level. Calculate the test statistic to 2 decimal places.

The average of 17 multiple of 7 is 63 average is computed by adding a set of numbers and then dividing by the total number of those numbers.

By dividing the total number of values by the total number of numbers, the average can be computed. A mean is the mathematical average of a set of two or more data items. Common names for average include mean and mathematical mean. The term "mean" simply represents the average of the sample.

The average of a list of data represents the fundamental value of a group of data mathematically. The ratio of the total number of data points to the total number of units in the list is how it is technically defined. In statistics, the term "mean" also denotes the average of a certain set of numerical data.

To calculate average=

7+14+21+28+35+42+49+56+63+70+77+84+91+98+105+112+119/17

The amount owed at the end of the 6 years duration is $10865

The given parameters about the compound interest are

Principal Amount, P = $5300

Interest Rate, R = 8%

Time, t = 6 years

To calculate the amount owed, we make use of the following formula

A = P + CI

Where

Compound interest, CI = P(1 + R)^t - P

So, the equation becomes

A = P + P(1 + R)^t - P

Evaluate the like terms

A = P(1 + R)^t

In this question, the formula is given as

A = P(1 + r/n)^nt

Where

n = 12, i.e compounded monthly

Substitute the known values in the above equation

A = 5300 * (1 + 8%/12)^(6*12)

Express 8% as decimal

A = 5300 * (1 + 0.08/12)^(6*12)

Evaluate the sum

A = 5300 * (1.01)^(6*12)

Evaluate the exponent

A = 5300 * 2.05

Evaluate the product

A = 10865

Hence, the value of the amount after 6 years is $10865

Answer: y =  4x -11

Remeber  the slope is the gradient -> m

Our equation to find the problem:

Substitude:

y-9 = 4(x-5)                       because y1= 9, x1 = 5 and m = 4

The perimeter (adding up all the sides) of a rectangular piece of land is 228 feet. The length of the land is 74 feet and its width is 154 feet.

The perimeter of a closed plane figure is referred to in geometry. You might have studied perimeter calculations in school. An equilateral triangle has a 27-foot perimeter if each of its nine sides is the same length. The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimeter, meters, inches, and feet.

Given,

Perimeter = 228 feet

Length = x

Width = 2x + 6

Perimeter of rectangle = Length + Width

228 = x + 2x + 6

228 = 3x + 6

228 - 6 = 3x

What are linear inequalities?

When two linear expressions are compared using the inequality symbols, that is an expression of a linear inequality.

Given, Time is taken for solving single math question = 12 minutes

          Time is taken for solving single science question = 5 minutes

Let 'x' be the total number of math questions and 'y' be the total number of science questions.

Then,

The total time taken for 'x' math questions = 12x minutes

The total time taken for 'y' science questions = 5y minutes

So, as defined in the question, we get

Total time she wants to spend practicing < 60 minutes

i. e. 12x + 5y < 60 .................... (i)

Now, we check this condition for each answer choice

A) x = 3 and y = 5, substituting values in equation (i)

The solution of the system of equations is

x = -13/20 , y = 9/2 , z = 19/20

Given, a system of equations

x + 5y - 3z = 19

2x - 3y + 4z = -11

4x + y - 2z = 0

On multiplying eq (1) by 2, we get

2x + 10y - 6z = 38

On subtracting eq (1) and (2), we get

13y - 10z = 49 ... (4)

Now, On multiplying eq (2) by 2, we get

4x - 6y + 8z = -22

On subtracting eq (3) and (2), we get

7y - 10z = 22 ... (5)

Now, on subtracting eq (4) and (5), we get

6y = 27

y = 9/2

On substituting the value of y in Eq (5), we get

z = 19/20

Now, On substituting the value of y & z in Eq (1), we get

x + 5(9/2) - 3(19/20) = 19

x + 45/2 - 57/20 = 19

x + 393/20 = 19

x = -13/20
