The mean is the average...to find the mean, add up all the numbers, then divide by how many numbers there are.
Example :
ur set of numbers : 1,2,3,4
add up all the numbers and divide by how many there are :
(1 + 2 + 3 + 4) / 4 = 10/4 = 2.5...so 2.5 is ur mean (average)
B: 78.50
If you plug in 5 for r, then you get 3.14 * 25, which is equal to 78.5
Hope this helps!
You're given d = 10
10 = -1.5t<span>2 = 110
</span>
![t^{2}](https://tex.z-dn.net/?f=%20t%5E%7B2%7D%20)
= 220/3
since t
![\geq](https://tex.z-dn.net/?f=%20%5Cgeq%20)
0
t =
![\sqrt 220/3](https://tex.z-dn.net/?f=%20%5Csqrt%20220%2F3)
I apologize if this is wrong!
First error is that the legs are a and b so a should be x and b is 6 and c is 10 the second error is at the end they did not take the square root to get x by itself the real answer should be
X^2 +6^2=10^2
X^2+36=100
X^2 =64
X=8
