4x°=75-x° this might be wrong but I’m sure
Mean
add up numbers and divide by how many there are
(1+1+5+3+6+6)/7=3 and 2/3
Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ - 10, 10 ], thus
f(b) = f(10) = 10² + 9(10) + 18 = 100 + 90 + 18 = 208
f(a) = f(- 10) = (- 10)² + 9(- 10) + 18 = 100 - 90 + 18 = 28, thus
average rate of change =
=
= 9
The equation would be 30+3m=162 then you solve the problem
