Answer: 9%
Step-by-step explanation:
(difference between two numbers/ original number) x 100 = 9%
(196 200 - 180 000/ 180 000) x 100 = 9%
Answer:
Z value for the first pump = -0.68
Z value for the second pump = 0.45
Step-by-step explanation:
Data provided in the question:
Mean labor cost to repair a heat pump = $90
Standard deviation = $22
Labor cost for the first, X₁ = $75
Labor cost for the Second, X₂ = $100
Now,
Z value for the first pump = [X₁ - Mean] ÷ Standard deviation
thus,
Z value for the first pump = [ $75 - $90] ÷ $22
= - 0.68
Z value for the second pump = [X₁ - Mean] ÷ Standard deviation
thus,
Z value for the second pump = [ $100 - $90] ÷ $22
= 0.45
We can present these coordinates in tabulate form
x y
-1 0.8
0 2
1 5
2 12.5
We work the multiplicative rate of change by finding out the increase ratio
12.5 ÷ 5 = 2.5
5 ÷ 2 = 2.5
2 ÷ 0.8 = 2.5
The ratio results in the same ratio every time, which is 2.5
The multiplicative rate of change = 2.5
