Question:

(a) Binomial probability distributions depend on the number of trials n of a binomial experiment and the probability of success p on each trial. Under what conditions is it appropriate to use a normal approximation to the binomial? (Select all that apply.)

nq > 10

np > 5

p > 0.5

np > 10

p < 0.5

nq > 5

(b) What is the probability of "12" or fewer successes for a binomial experiment with 20 trials. The probability of success on a single trial is 0.50. Use the normal approximation of the binomial distribution to answer this question. (Round your answer to four decimal places.)

Answer:

(a) The correct options are np > 5 and nq > 5

(b) P(x ≤ 12) = 0.8133

Which is the diameter of a rectangle whose circumference is 13653 cm and one side is 5431 cm​
leonid [27]

Answer:

See below

Step-by-step explanation:

If by circumference you meant perimeter and diameter you mean length, then here is my answer.

Perimeter = 2L+ 2W

13653= 2*L + 2*5431

13653= 2L + 10862     Subtract 10862 from both sides

2791= 2L Divide by 2

L= 1395.5

The diameter is 1395.5
