Answer:
integers
Step-by-step explanation:
so negative and positive are numbers in questions so no.
and def not Imaginary numbers
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.
Answer:
<u>Based on the results the boutique could be located there.</u>
<u>Step-by-step explanation:</u>
Note: The average income (the mean) is calculated by summing the total incomes then divided by the total sample–9.
The mean ù (average income) = $28,000 + $24,000 + $26,000 + $25,000 + $23,000 + $27,000 + $26,000 + $22,000 + $24,000= $225,000/9= $25,000 (which is ≥ $25,000.
Based on the results of the p-value, using the 5% significant level <em>we fail to reject the null hypothesis</em> (ú≥25,000).
Answer: 45
Explanation:
When finding the equations for the numbers, remember that it is not three consecutive numbers: it is three CONSECUTIVE ODD numbers. Thus:
First number = x
Second number = x + 2
Third number = x + 4 (second number + 2)
x + x + 2 + x + 4 = 141
3x + 6 = 141
3x = 135
x = 45
This tells us that the smallest number (x) is 45. To check our answer, we can plug this value in for x:
45 + 45 + 2 + 45 + 4 = 141
141 = 141
This also tells us that the other two numbers would be 47 and 49, and 45 + 47 + 49 also equals 141.
