Answer:

k(-1) = 7.

Step-by-step explanation:

k(-1) is the value of the function k when x = -1.

You read this off the graph.

Find the value of the point on the graph which corresponds to x = -1. From x = -1 on the horizontal axis move straight up until you meet the graph of k. Now look horizontally to the right and read off the value on the vertical

y-axis

You'll find it is 7.

Answer:

The standard deviation of the price she will get is $8,371.58.

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The variance of the uniform distribution is given by:

$V = \frac{(b-a)^{2}}{12}$

The standard deviation is the square root of the variance.

Uniformly distributed between $204,000 and $233,000

This means that $a = 204000, b = 233000$

$V = \frac{(b-a)^{2}}{12} = \frac{(233000 - 204000)^{2}}{12} = 70,083,333.33$

The standard deviation is the square root of the variance. So

$S = \sqrt{70,083,333.33} = 8,371.58$

The standard deviation of the price she will get is $8,371.58.

percent change = [ (difference between initial value and final value) ÷ initial value] x 100

⇒ percent change = [ (50 - 48) ÷ 48 ] x 100 = 4.17% (nearest hundredth)
