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:
B. 7
Step-by-step explanation: 6/24= 1/4 so 7/24>1/4
Answer:
A'(-6,4)
Step-by-step explanation:
A transformation of (x, y) → (x-3, y + 2) means:
- x coordinate gets translated 3 units left [we subtract 3 from original x coordinate]
- y coordinate gets translated 2 units up [we add 2 to original y coordinate]
The original x coordinate is -3 so we subtract 3 from it to get:
New x = -3 -3 = -6
The original y coordinate is 2 so we add 2 to get:
New y = 2 + 2 = 4
So A' is
A'(-6,4)
