Answer:

r = -4

Step-by-step explanation:

Step 1: Write out equation

4r + 8 + 5 = -15 - 3r

Step 2: Combine like terms

4r + 13 = -15 - 3r

Step 3: Add 3r to both sides

7r + 13 = -15

Step 4: Subtract 13 on both sides

7r = -28

Step 5: Divide both sides by 7

r = -4

The mean and standard deviation when presenting results?

krek1111 [17]

Answer:

Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value. A low standard deviation means that most of the numbers are close to the average. A high standard deviation means that the numbers are more spread out.
