Answer:

3

Step-by-step explanation:

The first step is to find the mean of the data set

mean = \frac{4+3+4+5+6+6+8+4}{8} = \frac{40}{8} = 5

Next take the absolute value of the difference between each data member and the mean, that is

| 4 - 8 | = | - 4 | = 4

| 3 - 8 | = | - 5 | = 5

| 4 - 8 | = | - 4 | = 4

| 5 - 8 | = | - 3 | = 3

| 6 - 8 | = | - 2 | = 2

| 6 - 8 | = | - 2 | = 2

| 8 - 8 | = | 0 | = 0

| 4 - 8 | = | - 4 | = 4

Finally find the mean of the absolute values

mean absolute value = \frac{4+5+4+3+2+2+0+4}{8} = \frac{24}{8} = 3

Find the average value of the function f(x)=−4sin(x) on the interval [π2,3π2] and determine a number c in this interval for whic
Ber [7]

Answer:

Step-by-step explanation:

The average value theorem sets:

if f (x) is continuous in [a, b] and derivable in (a, b) there is a c Є (a, b) such that

\frac{f(b)-f(a)}{b-a}=f'(c) , where

f(a)=f(π/2)=-4*sin(π/2) = -4*1= -4

f(b)=(3π/2)=-4*sin(3π/2) = -4*-1 = 4

\frac{4-(-4)}{(3\pi/2)-(\pi/2)}=f'(c)

\frac{8}{\pi }=f'(c)

f'(x)=-4cos(x) ⇒

f'(c)=-4cos(c)=\frac{8}{\pi }\\c=acos(\frac{-2}{\pi })\\

c≅130
