Answer:
<em>The size of the sample 'n' = 2401</em>
Step-by-step explanation:
<u><em>Step:1</em></u>
Given that the margin of error = 2 % = 0.02
The margin of error is determined by
we know that the proportion
<u><em>Step:2</em></u>
<em>The margin of error is determined by </em>
<em> </em><em></em>
√n = 49
Squaring on both sides, we get
n = 49 × 49
n = 2401
<u>Final answer:-</u>
<em>The size of the sample 'n' = 2401 </em>
Answer:8x-7x=0
Step-by-step explanation:
8x-7x=0
We simplify the equation to the form, which is simple to understand
8x-7x=0
We move all terms containing x to the left and all other terms to the right.
+8x-7x=0
We simplify left and right side of the equation.
+1x=0
We divide both sides of the equation by 1 to get x.
x=0
The answer is that I think it is 5
