Answer:
A
Step-by-step explanation:
PR / Sin(Q) = QR / Sin(P)
53 / Sin(90) = 45 / Sin(P)
53 / 1 = 45 / Sin(P)
Sin(P) = 45 / 53
Sin(P) = 0.8490566038
P = 58.11 degrees
The answer is 0.01333 repeating :)
Answer:
Mean 24, standard error 0.8
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation, also called standard error
In this problem, we have that:
What are the mean and the standard error of the sample mean?
By the Central Limit Theorem, mean 24 and standard error
