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
Answer:
thanks but wheres the question???????????/
Step-by-step explanation:
Answer:
Step-by-step explanation:
At first sight this equation has 3 terms. Multiply all 3 of them by 10 to remove the fractions:
4b + 13 = 4(b - 5)
Carrying out the multiplication, we get:
4b + 13 = 4b - 20
This can never be true (13 is never equal to -20), so this equation has NO SOLUTION.
