If each hour is 55, lets divide 150 by 55.
She charged you for 2.7 hours (almost 3) of service
Answer:
ill give u the answer if u do 73 divided by 2628
Step-by-step explanation:
answer: a. input, output
explanation: this is because the x values can not repeat in a function. if they do, they would not pass the vertical line test, and therefore it would not be a function. so, each input and output must be different values. :)
88 is your answer 100% sure.

Answer: 0.0010
Step-by-step explanation:
Given the following :
Population Mean(m) = 4.2 years
Sample mean (s) = 3.9
Standard deviation (sd) = 0.6
Number of samples (n) = 38
Calculate the test statistic (z) :
(sample mean - population mean) / (sd / √n)
Z = (3.9 - 4.2) / (0.6 / √38)
Z = (- 0.3) / (0.6 / 6.1644140)
Z = -0.3 / 0.0973328
Z = - 3.0822086
Z = - 3.08
From the z table :
P(Z ≤ - 3.08) = 0.0010
