Answer:

Step-by-step explanation:
The range is set of all y-values. The range starts from minimum value to maximum value.
We don't have minimum value (approaching negative infinity.)
We have maximum value at x ≈ 2 equal 6.
Therefore the answer is
-inf <= y <= 6. But we don't usually write that. Instead, we cut out -inf and we get —

The first has no r , only 0 since it is a straight line.
Answer:
x=-1
Step-by-step explanation:
-15=22x+7
Subtact 7 both sides
-15-7=22x+7-7
-22x=-22
Divide both sides by -22
-22x=-22
x=-1
Answer:
A. Because the sample size is very large.
Step-by-step explanation:
The sample is quite large, so the t test is safe. With a sample size of at least 100, this test is going to be safe.
So the correct answer is:
A. Because the sample size is very large.
