Answer:
x = 8
Step-by-step explanation:
-4x + 6(6 - 2x) = -7x - 36
-4x + 36 - 12x = -7x - 36
-16x + 36 = -7x - 36
<u> +36 +36</u>
-16x + 72 = -7x
<u>+16x +16x</u>
72 = 9x
divide by 9
<u><em>x = 8</em></u>
I want to say that the answer is 19/4
The
formula for the population proportion is:
n = p ± Zc
where p =
confidence level = 0.2
n =
proportion = 0.22
= standard error = 0.01
Finding for Zc:
.20+(.01)=.22
Zc = 2
Referring to Critical value table for standard
normal curve, a Zc value of 2 is equivalent to 95% Confidence Level.
Answer: 95% Confidence Level
