Work shown above! Answer is
a = 144
b = 67
x + 5/2 = 2(x + 3)
D. -7/3
Start on -7 since it is the y intercept(b). 4/1 is the slope. So from seven you would go up 4 right 1.
<span>3 is 1.0 below the mean. That is 1.0 / 0.9, or 1.1111... standard deviations below the mean.
So look up z < -1.11 on your graphing calculator.
It should be around 0.1335 or 13.35%</span>
Answer:

Step-by-step explanation:
Given
See attachment
Required
Determine the slope of the line
From the attachment, we have the following points

and

The slope m is then calculated using:

Substitute values for the x's and y's




<em>Hence, the slope is 0</em>
