Answer:
The correct option is;
e. 2500
Step-by-step explanation:
The formula for sample size is given by the following formula;
At 95%, z = 1.96
ε = Margin of error = 0.02 = 2%
Finding the sample size, n, given only the margin of error is by the following formula;
Margin of error = 100/√n
Therefore, we have;
2 = 100/√n
√n = 100/2 = 50
n = 50² = 2500
Therefore, the correct option is e. 2500.
Answer:
The answer would be 1/6 kids are wearing shirts that are neither blue or white.
Step-by-step explanation:
So, to make this easier, lets convert 2/3 to a same denominator fraction.
We must ask, how many times does 3 go into six?
We multiply 3 by 2 and get six. We then multiply the numerator of 2 by the same, getting 4.
Our new fraction is 4/6 which is equal to 2/3.
Then we add 4 to 1, making it 5. That is the amount of students wearing blue and white shirts, which means
1/6 of the kids in the class are wearing shirts that are neither white nor blue.

Answer:
D
Step-by-step explanation:
The answer is B, 30 x 5 The answer is reasonable. Ryder is correct. It reasonable because if 25 x 5 is 125, then 30 x 5 won't be too much to be unreasonable. 30 x 5 is 150, therefore it is only 25 windows higher, so it is reasonable. Hope this helps! :)
