Answer:
The standard deviation for the number of defective parts in the sample is 1.88.
Step-by-step explanation:
The sample is with replacement, which means that the trials are independent, and thus, the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
68 defective out of 400:
This means that
From the shipment you take a random sample of 25.
This means that
Standard deviation for the number of defective parts in the sample:
The standard deviation for the number of defective parts in the sample is 1.88.
Answer:
c =9.7 cm
Step-by-step explanation:
Law of sines:
sin (82) / c = sin(55) / 8
0.9903 / c = 0.8192 / 8
c = 0.9903 * 8 / 0.8192
c =9.7 cm
The angles x and 55.1 degrees are COMPLEMENTARY ANGLES. Please look up that term if necessary.
Subtract the angle 55.1 degrees from ( what? ) to obtain angle x.
