Answer:
D. 54,900
Step-by-step explanation:
We have been given that the salary of teachers in a particular school district is normally distributed with a mean of $50,000 and a standard deviation of $2,500.
To solve our given problem, we need to find the sample score using z-score formula and normal distribution table.
First of all, we will find z-score corresponding to probability 
using normal distribution table.
From normal distribution table, we get z-score corresponding is 
.
Now, we will use z-score formula to find sample score as:
, where,
= Z-score,
= Sample score,
= Mean,
= Standard deviation
Therefore, the salary of $54900 divides the teachers into one group that gets a raise and one that doesn't.
Answer:
The rate of tax is 0.9% of the actual business amount.
Step-by-step explanation:
Given that:
Tax amount = $1035
Business value = $115,000
So, for finding the rate, we will have to divide the tax amount by business value and multiply it by 100 as follows:
Rate = 1035/115,000 * 100
By simplifying we get:
Rate = 0.009 *100
Rate = 0.9 %
This means that the tax rate is 0.9% of the original amount.
