For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It is the slope
b: It is the cut point with the y axis
We have the following equation:
Thus, the cut point with the y axis is -8. Therefore, we discard options C and B.
It is observed that the slope is positive so the correct graph is option B.
Answer:
Option B
Option a is correct. The calculated answer is 0.150
<h3>How to get the value using the cdf</h3>In order to get P(0.5 ≤ X ≤ 1.5).
This can be rewritten as
p = 0.5
and P = 1.5
We have the equation as
This would be written as
1.5²/16 - 0.5²/16
= 0.1406 - 0.015625
= 0.124975
This is approximately 0.1250
