1 answer:

4 0

The Equation Could Be:
E = Amount Each Freind Will Get
N = Friends.
130/n = E

130/10 = E

130/10 = 13

13 = E

Each Friend Will Get 13 Dollars.

In this problem, we explore the effect on the standard deviation of adding the same constant to each data value in a data set. C

Answer:

A, Adding a constant does nothing to the standard deviation

Step-by-step explanation:

I'm gonna assume s=standard deviation

The standard deviation is just the square root of the second moment minus the first moment squared

Because we were not told otherwise I think it's pretty safe to assume that all events are equally likely

Let's start by calculating the first moment (AKA The mean)

1/5(8+16+14+8+16)= 12.4

Let's then find the second moment

1/5(8²+16²+14²+8²+16²)= 167.2

√(167.2-12.4²)=3.6661

While I could just tell you that adding something to the standard deviation (and the variane as well) doesn't do anything let's calculate it for fun

same process

.2(16+24+22+16+24)= 20.4

.2(16²+24²+22²+16²+24²)=429.6

√(429.6-20.4²)= 3.6661

Answer:

The answer in the attached figure

Step-by-step explanation:

Let

x------> the abscissa

y-----> the ordinate

we know that

$y=2x$ -----> given problem

The domain is $[-1, 0, 1]$

For $x=-1$

$y=2(-1)=-2$

The point is $(-1,-2)$

For $x=0$

$y=2(0)=0$

The point is $(0,0)$

For $x=1$

$y=2(1)=2$

The point is $(1,2)$
