Answer:
The decimal point should be moved 3 units to the right, and the result of the multiplication is 4560.
Step-by-step explanation:
Multiplication of a decimal by the nth power of 10:
In this case, the decimal point should be moved n units to the right.
Division of a decimal by the nth power of 10:
In this case, the decimal point should be moved n units to the left.
In this question:
We multiply the decimal 4.56 by 1000.
1000 is the 3rd power of 10, because 
. So the decimal point should be moved 3 units to the right, and the result of the multiplication is 4560.
The frequency of A's would be 16.
The following would be the relative frequencies after the initial .08.
.18, .45, .15, .14.
To find the frequency of A, start by subtracting all of the other values from the total number. There are 200 total students, so subtract the other grade ranges.
200 - 36 - 90 - 30 - 28 = 16.
Now to find all of the frequencies, just divide each value by the total (200).
36/200 - .18
90/200 = .45
30/200 = .15
28/200 = .14
Area = L x W
Area = 32.5 x 21
Area = 682.5
