Answer:
a²- b²=(a+b)(a-b)
a² + b²=(a+b)²-2ab or (a-b)²+2ab
(a + b)³=a³+3a²b+3ab²+b³ or, a³+b³+3ab(a+b)
Area of a circle = pi* r^2
50.24 = pi* r^2
divide both sides by pi and get...
15.99188868 = r^2
the square root of that is 3.998985957 which rounds to 4
Changing from Two-sigma limits to three-sigma limits helps to reduce the probability that defects will be generated by the process. Hence the correct answer is C.
<h3>
What is a Two-Sigma Limit?</h3>
This is used to refer to the inclusion of about ninety-five percent of data plotted on the normal distribution curve.
Three sigma-limit on the other hand is a statistical calculation where data fall within three standard deviations from a mean.
If in a manufacturing firm, the quality control unit issues out a polity to reject products that are within two standard deviations to their accepted mean, then more errors will be captured thus resulting in a lot of loss or defective products.

Answer:
i think 38/60? simplified 19/30, im not sure..?
Step-by-step explanation:
20 percent of 60 is 12
1/6 is 10
12 plus 10 is 22
60- 22 is 38
