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.
Answer: The surface area of the cube is 385 mm^2.
When we are finding the surface area of a shape, we need to add up all the areas of each face. In this case, there are 6 faces.
Each face is the shape of square with sides of 8 mm. So the area of each face is 8 x 8 = 64 square mm.
Since we have 6 faces, we will multiply 64 by 6 to get 384 mm^2 in all.
