Answer: c.97.5 th percentile : $15.50; 2.5 th percentile : $12.50
Step-by-step explanation:
Since the hourly salaries of everyone in the company are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = hourly salaries
µ = mean salary
σ = standard deviation
From the information given,
µ = $14
σ = $0.75
Looking at the normal distribution table, the z score corresponding to the 2.5 th percentile(0.025) is - 1.96
- 1.96 = (x - 14)/0.75
x - 14 = 0.75 × - 1.96 = - 1.47
x = - 1.47 + 14
x = $12.53
Approximately, x = $12.5
Looking at the normal distribution table, the z score corresponding to the 97.5 th percentile(0.975) is 1.96
1.96 = (x - 14)/0.75
x - 14 = 0.75 × 1.96 = 1.47
x = 1.47 + 14
x = $15.47
Approximately, x = $15.5

Answer:
A' = {1, 4, 6}
Step-by-step explanation:
The complement can be found by deleting all of the members of A from U.
Here, we have highlighted the elements of A in U, so the complement is all of the elements that are not highlighted.
U = {1, 2, 3, 4, 5, 6}
A' = {1, 4, 6} . . . . . . . . complement of A
Answer: The explanation of the given addition is mentioned below.
Step-by-step explanation:
Since Here we have numbers 324 and 231.
So if we want to add these two numbers then at first we should add 4 and 1, That is 4+1= 5, which is the once place digit of our answer.
Now we should add 2 and 3 , that is , 2+3 =5 which is the tense place digit of our answer.
Finally we should add 3 and 2 the result is 3+2= 5 , which is the hundreds place digit of our answer.
Thus the complete result is 555.
