You can use the ASA postulate which means angle side angle. if 2 angles and the including side are congruent to the corresponding parts of another triangle then the triangles are congruent. hope that helps :)
Answer:
11.72
Step-by-step explanation:
6.76 + 4.96 = 11.72
Answer:
about 11 times
Explanation: 120- 49.95= 70.5
70.5÷ 5.95= 11.7
Answer:
Yes
Step-by-step explanation:
move the 9 over to the 3x and the get y by itself so divide 3x and 9 by 3 once you move the 9 over
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
