-6z = 72
Divide both sides by -6
-6z = 72
/-6 /-6
z = -12
Answer:
any score that lies between 88.8 and 97.2 is within one std. dev. of the mean
Step-by-step explanation:
One std. dev. above the mean would be 93 + 4.2, or 97.2. One std. dev. below the mean would be 93 - 4.2, or 88.8.
So: any score that lies between 88.8 and 97.2 is within one std. dev. of the mean.

Answer and Step-by-step explanation:
Solve for m.
<u>First, distribute the 5.</u>
5 + 20m - 2m = -13
<u>Combine like terms.</u>
5 + 18m = -13
<u>Subtract 5 from both sides of the equation.</u>
18m = -18
<u>Divide by 18 to both sides of the equation.</u>
<u>m = -1 <- This is the answer.</u>

Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm. If all the scoops are evenly distributed, they would all be 3.8 cm tall.
<h3>How to find the mean value of a data set?</h3>
The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.
If the data set consists of values
x_1, x_2, ..., x_n
, then we get the mean value as:
