B. because your deposit (d) has to be more than 100 and 46.04+53.96 equals 100
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
The answer is 11/8 but if u have to simplify to mixed fraction it would be 1 3/8. In decimal form its 1.375.
7 - 5 * 8 + 5 over 8
7 - 40 + 5 over 8
7 - 45/8
7 * 8/8 - 45/8
56/8 - 45/8
56 - 45 over 8
11/8
1 3/8
