The answer is 24 because 8*3
Hello from MrBillDoesMath!
Answer: 8 * pi (inches^2)
Discussion:
From Plane Geometry the circumference of a circle of radius "r" is
2 * pi * r
In this case, AB is a radius of the circle so the circumference is
2 * pi * 4 = 8 pi

In one sample t-test, you compare it to some value that you already know to represent the population mean. In the t-test for correlated groups, the statistic is the difference between your two samples, which you test against the population mean difference.
Answer:
99.9973 %
Step-by-step explanation:
This is a binomial probability distribution.
Since the probability of satisfactory welds = 97% = 0.97 and the probability of defective welds = 3% = 0.03.
Since there are 3 welds and we require at least one being defective, our binomial probability is
P(x ≥ 1) = 1 - P(x ≤ 0) = 1 - P(0) = 1 - ³C₀(0.03)³(0.97)⁰ = 1 - 1 × 0.000027 × 1 = 1 - 0.000027 = 0.999973 × 100% = 99.9973%
Answer:
5.5
