Step 1. Find the mean. To do that, you add all the numbers and divide that number by how many numbers you have which is 10. All the numbers together is 650. That divided by 10, is 65. That is your mean.

Step 2. Once you have that, subtract the mean from all 10 numbers.

Step 3. Find the mean of the 10 numbers which you have subtracted 65 (the mean) from. If the number you subtracted is a negative, make it a positive.

a park is 4 times as long as it is wide. if the distance around the park is 12.5 kilometers, what is the area of the park?

blsea [12.9K]

So, first, what are the two sides?

let's call then x and y

we know that 2(x+y)=12.5 (that's the distance around)

so that means that x+y=6.25 (I just divided both by 2)

now, x=4y (from "4 times as long as it is wide")

so we can substitute:

x+4x=6.25

5x=6.25

x=1.25

so one side, is 1.25 and the other will be 1.25*4=5

and for the area we multiply the two:

1.25*5=6.25 square kilometers, and this is the answer!
