Question: Parameter of statistics?
Explanation:
Parameters summarizes data for the whole population while statistics summarizes sample data. In other words, statistics is a sub-set of parameters. In the mentioned case of mark, the data provided summarizes his entire sprinting career and thus is a case of parameters.
The easiest way to do this is to put the height in terms of radius. If diameter is 2 times the radius, then d = 2r. If the height is 3 times the diameter and diameter is twice the radius, then d = 2r, h = 3d, and 3d = 6r. Therefore, h = 6r by the transitive property of equality. Anyway...The formula for surface area of a cylinder is SA= 2 pi r^2 + 2 pi r h. Let's sub in what we know now, which is that SA = 126 and h = 6r: 126 pi = 2 pi r^2 + 2 pi r (6r). Simplifying that we get
126 pi = 2 pi r^2 + 12 pi r^2. Simplifying even further gives us
126 pi = 14 pi r^2. Divide both sides by 14 pi to get 9 = r^2. Now take the square root of both sides to get that r = +/- 3. But since we know that radius cannot be negative, the answer is that the radius is 3.
14 gallons I believe
Let me know if this helped!
Answer: 13.7
Step-by-step explanation: I used the pythagoream theorum.
Since there are 25 students and there’s 21 at the zoo you would end up having 21 out of 25 and 21 out of 25 as a percentage is 84% because you have to look at 25 as a whole and that whole would be 100% so 84 out of 100% is equal to 21 out of 25
