Given that rate of commission earned by the real estate agent = 4%
Given that required commission that real estate agents wants to earn = $7000.
Now we have to find about how expensive of a house does he have to sell to earn $7000.
So let the cost of house = $x
then commission earned = 4% of x
Given commision is $7000 so both quantities will be equal and we get equation:
4% of x = 7000
0.04x = 7000
x = 7000/0.04
x = 175000
Hence final answer is $175000.
Yes,it's the correct shape.

Answer:
The z score for bolt of diameter 18.12 mm is 1.20.
Step-by-step explanation:
Let <em>X</em> = diameter of bolts.
It is provided that the random variable <em>X</em> follows a Normal distribution with mean, <em>μ</em> = 18 mm and standard deviation, <em>σ</em> = 0.10 mm.
A <em>z</em>-score is a standardized score, a numerical, that defines how far a data value from the mean.
The distribution of <em>z</em>-scores is defined by the Standard Normal distribution.

The formula to compute the <em>z</em>-score is:

The value of the diameter of a bolt is, <em>x</em> = 18.12 mm.
Compute the <em>z</em>-score for this value as follows:

Thus, the z score for bolt of diameter 18.12 mm is 1.20.
