I think is
9 + x = 16 + 27
9 + x = 43
x = 52
on my calculator 48^1/5 equals 2.168943542
but out of a fraction 1/5 equals 0.2 ( they both equal the same thing)
2.168943542
Answer:
1877 computer users
Step-by-step explanation:
We have that for 95% of confident, the value of z has a value of 1.96 (attached table about it), they also mention the margin of error (E) that is 10 and finally the standard deviation (sd) that has a value of 221.
We apply the following formula:
n = [z * sd / E] ^ 2
replacing:
n = [1.96 * 221/10] ^ 2
n = 1876.27
that is, the minimum sample size is 1877
