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
Answer:

Step-by-step explanation:
Rewrite 32 as the product of 16 and 2:

Apply exponent rule 

Rewrite 16 as 4²:

Apply exponent rule 

The value of seven is in the thousands place and is 10 time the number seven if it were at the hundreds place, which is where 2 is.
