Answer: 40000
Step-by-step explanation:
The formula to find the sample size is given by :-
, where p is the prior estimate of the population proportion.
Here we can see that the sample size is inversely proportion withe square of margin of error.
i.e.
By the equation inverse variation, we have
Given :
Then, we have
Hence, the sample size will now have to be 4000.
Answer:
40
Step-by-step explanation:
The figure is a rectangular prism, so the formula would be Volume = length x width x height.
length = 6 cm
width = 2 cm
height = 2 cm
If you plug everything you have in the problem into the volume equation, you would get : Volume = 6 cm x 2
cm x 2
cm.
Without a calculator, I would first turn the mixed numbers into improper fractions.
- 6
=
- 2
Volume = x
x
When you multiply everything together you should get .
As a mixed number, that would be 40
