Answer:
- 4
Step-by-step explanation:
The average rate of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ - 2, 2 ]
f(b) = f(2) = 9 ← from table value of f(x) for x = 2
f(a) = f(- 2) = 25 ← from table value of f(x) for x = - 2, thus
average rate of change = =
= - 4
Answer:
Mean, m = 72
Step-by-step explanation:
It is given that, Carl earned grades of 62, 78, 59, and 89 on four math tests.
It is required to find the mean of his grades.
Mean of a data is given by :
Sum of observations is 62 + 78 + 59 + 89 = 288
Total no of observations are 4
So, mean of his grades is :
So, the mean of his grades is 72.
