When 0 is in the numerator, then the whole fraction becomes equal to 0.
However if 0 is in the denominator, then it is undefined.
1.)There is one outlier, indicating very few books were checked out on that day
This is because there is one day where only 2 books were checked out while on all of the other days 35-45 books were checked out.
2.) 0; it represents no correlation between x and y
This is because no matter the age they could answer 17 questions
Hope this helps!
21x -15 + 5 = 10x - 5
21x -5 = 10x
11x = 5
x = 5/11
To solve for r, you would start by subtracting p from both sides.
2m - p = -q/r
Multiply everything by r.
2mr - pr = -q
Factor r out of the left side of the equation.
r(2m - p) = -q
Divide both sides by (2m - p).
r =
.
