Step-by-step explanation:
800(1-0.01)=\color{green}{792}
800(1−0.01)=792
6180(1-0.05)=\color{blue}{5871}
6180(1−0.05)=5871

\text{Find overall decrease:}
Find overall decrease:
6980(1-r)=6663
6980(1−r)=6663
\frac{6980(1-r)}{6980}=\frac{6663}{6980}
6980
6980(1−r)
=
6980
6663
1-r=0.954585
1−r=0.954585
-r=-0.045415
−r=−0.045415
Subtract 1
r=0.045415
r=0.045415
Divide by -1

Answer:
The mean.
Step-by-step explanation:
The mean is not robust.
The presence of an outlier greatly affects the value of a mean.
An example will illustrate this.
Find the mean of the numbers 2 3 5 6 34.
34 is an outlier. The mean = (2+3+5+6+34) / 5 = 10.
Now if we replace the outlier with a number closer to the others:
Say we have 2 3 5 6 8 :
The mean = (2+3+5+6+8) / 5 = 4.8 which is a much truer measure of centrality than 10.
The answer to that definition is a multiple. A multiple is any number that is not zero.

When Serena is 10, her mom is 3*10=30. Her mom is 20 years older than Serena.
If her mom's age divided by half is equal to Serena's, then she will be twice as old as Serena.
20 + 20 = 40
20 * 2 = 40
Serena will be 20, her mom will be 40.
