Answer:
1509
Step-by-step explanation:
We know that, formula for number of samples is,

When nothing is given, we take
and we know that
.
SE = 0.03 (the true proportion should remain withing 3%)
Putting the values we get,


Therefore, the sample required to estimate the true proportion to within 3 percentage points is 1509.
Solution:
Given:

An integer is a whole number (not a fractional number) that can be positive, negative, or zero.
Writing each number as a sum of integers in three different ways,
A) The side length is 5 units since 5*5*5 = 125. You can guess and check to see which value multiplies with itself three times to get 125. Or you can take the cube root of 125 to get 5. You can type in 125^(1/3) to indicate you want the cube root of 125
b) The volume is 64 cubic units. Multiply the side length 4 by itself three times: 4*4*4 = 64.
