Step-by-step explanation:
Perimeter of base * by height.
94*15
1410
The square root of 10 because
sqrt(10) ^2 * 3.14 =
10*3.14 = 31.4
48.....

Answer:=21
Step-by-step explanation:
5+4(8−6)^2
=5+4(2^2)
=5+(4)(4)
=5+16
=21
This problem represents "binomial probability," because any given "experiment" can have only two possible outcomes: defective or not defective.
Here the "population" probability that a given microwave unit is defective is 0.015. We arbitrarily define "defective microwave" as a "success" and "non-defective microwave" as a "failure."
We can obtain binomial probability values from a calculator such as the TI-83, from a table or from the binomial probabilty formula. In all of these cases the number of samples is given and is n=20; the probability of "success" is also given and is p=0.015.
Case 1: What is the probability that exactly 1 microwave unit is defective?
Using the TI-83: binompdf(20,0.015,1) = 0.225, or 9/40.
Case 2: What is the p. that at most 2 are defective? Add together the binomial probabilities binompdf(20,0.015,0),binompdf(20,0.015,1),binompdf(20,0.015,2).
Result: 0.7391 + 0.2250 + 0.0326 = 0.9967.
Mean: The mean of a binomial probability such as this one is simply np, which in his case is 20(0.015)=0.30. Find and apply the formula for the standard deviation.
