Answer:
Mean= 31
Step-by-step explanation:
To find the mean you need to add all the number together and then divide by how many ever numbers there are.
In this case
25 + 25 + 30 + 35 + 40=155
There are 5 numbers so you would divide by 5
155/5
=31
Line Q, you always want the line that has as many dots on it as possible!! :)
23 is negative correlation

x =
9
That’s pretty easy you just have to basically y=mx+b
