The graph below plots a function f(x):
Karolina [17]
By definition we have that the average rate of change of the function is given by:
 AVR =  \frac{f(x2) - f(x1)}{x2 - x1}&#10;
 Substituting values we have:
 AVR = \frac{100 - 50}{2 - 0}
 Rewriting we have:
 AVR = \frac{50}{2}
 AVR = 25
 Answer:
 If x represents time, the average rate of change of the function f(x) in the first two seconds is 25.

7.1.13 Question Help Use the sample data and confidence level given below to complete parts (a) through (d). A research institut
r-ruslan [8.4K]

Answer:

The Point estimate of the Population proportion  E = 0.039≅0.04

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the sample size 'n' = 992

  and                                     x = 570

The Population proportion

                                   p = \frac{x}{n} = \frac{570}{992} = 0.5745

<u><em>Step(ii):-</em></u>

<u><em>The point estimate of the Population proportion is determined by</em></u>

<u><em></em></u>E =   2.576 \frac{\sqrt{0.574(1-0.574)} }{\sqrt{992} }<u><em></em></u>

E = 0.039≅0.04

<u><em>Final answer</em></u>:-

The point estimate of the Population proportion  E = 0.039≅0.04

<u><em></em></u>
