hammer [34]

Answer:

69,168

What is measure of angle R?
TEA [102]
I want to say it's 45 degrees. I got it by subtracting 180 and 90 then you get 90 and you divide that by 2. The reason I subtracted by 180 is because that's how many degrees a triangle is. I hope it helps.

The valve was tested on 210 engines and the mean pressure was 5.0 pounds/square inch (psi). Assume the population standard devia
Alina [70]

Answer:

1.6101529

Step-by-step explanation:

Given the following :

Number of samples (n) = 210

Sample mean (x) = 5

Population standard deviation = 0.9

Population mean (m) = 4.9

Since the standard deviation of the population is known, we can use the z statistic

Z = (x - m) / standard error

Standard error = sd / √n

Standard error = 0.9 / √210

Standard error = 0.9 / 14.491376

Standard error= 0.0621059

Z statistic = (5 - 4.9) / 0.0621059

Z statistic = 0.1 / 0.0621059

Z statistic = 1.6101529
