Answer:mean
Step-by-step explanation:
I would assume it’s the mean since that averages the 7 test scores it represents the data set well. Outlier and mode don’t describe a data set since they are quite unique within it.
18(y-5)^2=x+3
do the algebra to make it into =x form
x=18y^2-180y+447
then you take the form of the focus, you can do the math
(-215/72, 5)

</span>The answer to question 7 is 28x^3y^4.
Answer: i would say probably 3 or -3
