I hope your not that lost now.
Finding the range of a function y=f(x) is the same as finding all values that y could be. To do this, we can think of it this way: The range of f(x) is all the y-values where there is a number x with y=f(x).
Answer:
2 cookies per dollar
Step-by-step explanation:
You can take any point on the line, turn it into a fraction and simplify.
For example: 4 cookies cost $2.
4 cookies per 2 dollar is 2 cookies per 1 dollar (divide by 2)
If you take another point, e.g., 14 cookies for 7 dollar, you'll be dividing by 7 to simplify and get the same answer.
Answer:
r = 0.9
Step-by-step explanation:
Correlation is denoted by r. r² is usually used to measure variation along the line as a fraction of the total variation.
We are told class attendance explained 81% of the variation in grade index among the students. Thus, for this regression, the variation is;
r² = 81%
Or r² = 0.81
Thus, the numerical value of the correlation r would be;
r = √0.81
r = 0.9
The answer is 
.
Please mark me as brainiest!
D. When you do the math, the results to everything should be t=9. D is the only outlier. Therefore, D is the answer in this case.
