Answer:
1006
Step-by-step explanation:
Take proportion, p = 62%
n = (Z² * pq) / M.E²
Margin error = 0.03
p = 62% = 0.62
q = 1 - p = 1 - 0.62 = 0.38
Zcritical at 95% = 1.96
n = (1.96² * (0.62*0.38)) / 0.03²
n = 0.90508096 / 0.0009
n = 1005.6455
n = 1006
Sample size = 1006

Step-by-step explanation:
Answer:
A. 20.5
Step-by-step explanation:
We can use the Pythagorean theorem to solve this equation for the missing side length, X.
a^2 + b^2 = c^2
We have a and b, we just need c, the hypotenuse.
14^2 + 15^2 = c^2
196 + 225 = c^2
421 = c^2
Now, we will square both sides:
The answer is about 20.5
