Let f (x) = 10/x-4 What is the average rate of change of f (x) from 2 to 8 ?

Enter your response as a decimal.

1.875

Step-by-step explanation:

The rate of change is the derivative of the function.

So, the rate of change is

f'(8) -  f'(2) = - 0.625 + 2.5 = 1.875

i think the amount would be $140.62

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
