Answer:
-y(7+y) =0
Step-by-step explanation:
-7y - y^2 = 0
Factor out a -y
-y(7+y) =0
Using the zero product property
-y =0 and 7+y =0
y=0 7-7+y = 0-7
y=0 y = -7
exhibit population for ten integers is 15,19,19,20,20,20,21,22,22,22 mean is 20 variance is 4
Step-by-step explanation:
- Mean is helps in finding the mid point of the data.
- Variance is the variability of data it was here.
- In order to get the data straight the combination of 4 was required.
- 4 is variance one data set was 19 other had to be 22.
- As mean is 20 three means had to be 20.
- from mean 20 4 is greater then 20 and 3 is less then 20.
- 15 being the lowest it compensated the variance to 4.
- Mathematically there are many ways to do this using function.
- This is to be found out at a traditional method.
- Reducing or increase the number as it was integers.
Based on the info u have given, i just guessing that its 7.2
I'm probably wrong though

Answer:17
Step-by-step explanation:
First you subtract 13-9 to find the distance between the 2 numbers. That gets you 4 but if the numbers are 2 spaces away from one another then that means that the number line increases by 2. Then you add 4 to 13 and that’s how you get 17.
