Step-by-step explanation:
B. X<(with line under)40
If you randomly purchase one item, the probability it will last longer than 9 years is; 11.12%
<h3>How to find the probability from z-score?</h3>
The formula for Z-score is;
z = (x' - µ)/σ
where;
x' = sample mean
µ = population mean
σ = standard deviation
Thus;
z = (9 - 7.9)/0.9
z = 1.22
From online p-value from z-score calculator, we have;
probability = 0.1112 = 11.12%

Answer:
The slope is 2.5
Step-by-step explanation:
y = 2.5x + 5 or
y =
5/2x + 5
When x=0, y = 5
When y=0, x = -2
