So you add all of the numbers of books owned by each student then divide it by 8, after you get the result you subtract the total by the number of books of each student individually (and if you get a negative it will be positive) then after you finish subtracting all 8 students book total you add up the numbers together and then you divide by 8 again and you get your mean.. hope this helped

A) To find the mean you have to add all of the values together and divide it by the total number of values. So, 8+9+9+7+8+6+9+8=64 ---> there are 8 numbers----> 64/8=8----> the mean is 8.
(B) Take each number and subtract it by the mean. For example 7-8= -1. Then take the absolute value of that number. For example. l7-8l= 1. Do that for every number. Add the differences together. 0+1+1+1+0+2+1+0=6. Divide the sum by the number of values added. 6/8= .75  This is the mean absolute value deviation.

In 36 years, Ishaan will be 3 times as old as he is right now. How old is he right now?
Lady_Fox [76]

Answer: He is 18 years old right now.

Step-by-step explanation:

Let the present age of Ishaan be x

After 36 years,

his age will be x+36

According to question,

it is mentioned that Ishaan will be 3 times as old as he is right now ,

So, we will frame it in equation:

x+36=3x\\\\36=3x-x\\\\36=2x\\\\x=\frac{36}{2}\\\\x=18\ years

Hence, he is 18 years old right now.

A 360 degree rotating sprinkler that sprays water at a radius of 11 feet is used to water a lawn. What is the Area of the lawn t
denpristay [2]

Answer:

Area=121\pi ft^2 in terms of \pi.

Step-by-step explanation:

A 360 degree rotating sprinkler will water a full circular region of the lawn.

The area of this circular region is calculated using the formula:

Area=\pi r^2

where r=11 feet is the radius of the circular region covered.

We substitute the value of the radius into the formula to get:

Area=\pi \times 11^2

Area=121\pi ft^2 in terms of \pi.

This is approximately 380.1 ft^2 to the nearest tenth
