The mean is 10.
To find the mean you add up all the numbers and divide by how many sets of numbers there were.
8+10+11+8+13=50
50/5=10.
Answer:
(X2+3)2
Step-by-step explanation:
First, you have to substitute in what f(x) equals for y since f(x) stands for y.
By doing this, the equation turns into (x2+3)2, because x2+3 is y, and 2 because the original equation way y2.
After you substitute, the answer is (x2+3)2.
Hey there!
Let solve this problem step by step :)
1. Convert 20/25 into a decimal. In order to do this, you will need to divide the numerator (the top part of the fraction) with the denominator (the bottom part of the fraction).
So,

as a decimal would be 0.8. (We divide 20 by 25)
2. Now, we take the decimal and multiply it by 100. To make it even simpler, just move the decimal, two places to the right. This makes it the percent. So,
0.8 ----> 80%
The final answer is 80%Thank you!
