Answer:

D. 14.32

Step-by-step explanation:

The formula for standard deviation is:

$SD = \sqrt{\frac{\sum | x-\mu|^2}{N}}$

The mean μ is 33.

The (x minus μ) squared are 361, 49, 49, 361 respectively.

So that the SD = $\sqrt{\frac{820}{4}} \approx 14.31782...$

A sequence is defined by the recursive function f(n + 1) = –10f(n).

Softa [21]

We are given

$f(n+1)=-10f(n)$

we are given

$f(1)=1$

At n=1:

we can plug n=1 into formula

$f(1+1)=-10f(1)$

$f(2)=-10f(1)$

$f(2)=-10*1$

$f(2)=-10$

At n=2:

we can plug n=2 into formula

$f(2+1)=-10f(2)$

$f(3)=-10f(2)$

$f(3)=-10*-10$

$f(3)=100$ ................Answer
