Answer:
59.87% probability of randomly selecting 10 production employees on a hot summer day and finding that none of them are absent
Step-by-step explanation:
For each employee, there are only two possible outcomes. Either they are absent, or they are not. The probability of an employee being absent is independent from other employees. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
5% of the production employees at Midland States Steel are absent from work.
This means that 
What is the probability of randomly selecting 10 production employees on a hot summer day and finding that none of them are absent
This is P(X = 0) when n = 10. So


59.87% probability of randomly selecting 10 production employees on a hot summer day and finding that none of them are absent
The solution to the quadratic equation is option D
19.625cm squared because you have to divide the diameter by 2 to get the radius.
Area of circle = pi times radius times radius
= 3.14 times 2.5 times 2.5
= 19.625cm squared
City hall to post office = 6 1/2 miles = represented by f
city hall to library site = 1 1/4 miles = represented by d
library site to post office = unknown. = represented by e
City hall to library site PLUS library site to post office IS EQUAL to city hall to post office
d + e = f
1 1/4 + e = 6 1/2
find e.
e = 6 1/2 - 1 1/4
e = 13/2 - 5/4
e = (13*2)/(2*2) - 5/4
e= 26/4 - 5/4
e = (26-5)/4
e = 21/4
e = 5 1/4 distance from library site to post office.
To check:
d + e = f
1 1/4 + e = 6 1/2
1 1/4 + 5 1/4 = 6 1/2
6 2/4 = 6 1/2
6 1/2 = 6 1/2
