Answer:
An applicant must score a minimum of 128
Step-by-step explanation:
To solve this question, we make use of the z-score formula.
Z = (X - mean)/standard deviation
Firstly, let’s list out the parameters from the question. From the question, we can deduce that:
Z = 1.5
X = ?
Mean = 110
Standard deviation =12
1.5= (X-110)/12
18 = X - 110
X = 110 + 18
X = 128
Part 1: should be C. Because the question said 1.2 added to a number.
Part 2:16.8
First you need to add 2 to every part of the equation. So -14+2, -2+2, and 22+2. After that you need to divide every part by 6, -12/6, 6/6, 24/6 which gives you the answer; -2
Hello,
To solve this problem, you should first put in it slope intercept form.
Here are the steps:
3y + 6 = -2x Add 6 to both sides
3y = -2x - 6 Divide both sides by 3
y = (-2/3)x - 2
The you can see that the slope is (-2/3) and the y-intercept is (0, -2).

Answer:
$323
Step-by-step explanation:
Hello! First you would need to divide $171 by 9 to see how much money she makes an hour....
$171 / 9 = $19 an hour
Now that you know how much she makes an hour, multiply that amount by 17 to find out how much money she will make if she works for 17 hours.
$19 * 17 = $323
She will make $323 if she works for 17 hrs. :)
Hope this helps!
