Answer:
6566
Step-by-step explanation:
The answer is 6566
you do not give a value for PI so I am using 3.14
V=PI x r^2 x H
you know volume and radius so put those into the equation
525 = PI (3.14) x 5^2 x H
525 = 3.14 x 25 x H
525 = 78.5 x H
divide both sides by 78.5
6.687 = H
round off answer as needed 6.7cm or 6.69cm
NOTE : the answer may vary slightly depending on the value of PI used.
but this is how you calculate the height.
Answer:
Matched pairs
Step-by-step explanation:
Here each athelete's time to complte 20 shuttle runs is to be compared with his/her time to complete the obstacle course is to be compared to determine their association
Inference for regression will be sutiable if their association is already known or if they can be realted via mathematical model.
Independent samples method can't be used as outcome of one experiment is to be matched with outcome of other experiment

Domain =
Range =
=============================================
Explanation:
The domain is the set of allowed x value inputs. We note that the left-most point is when x = -5, and this point has a closed or filled in endpoint, so we're including this x value in the domain.
The left piece has its other endpoint at x = -2, so the interval is part of the domain. We write that as is part of the domain's answer. The other part is . We include x = 1 but exclude x = 5 as there's a hole here.
Use the union symbol to glue the two intervals together and we end up with as the full domain.
----------------------------
The range is the set of possible y values. The lowest point is when y = -4, but we exclude this endpoint since there's an open hole here. The highest point is when y = 4. The range is which we write as
Since there are no gaps in the range, we don't use any union symbols here. Any y value between -4 and 4 is possible, other than y = -4 itself.
