Answer:
4
Step-by-step explanation:
8/2 = 4
Answer:
No
Step-by-step explanation:
We have:
n = 80,
p = 0.1 (10%)
q = 1 - p = 1 - 0.1 = 0.9
Usually we use
np > 5, and nq > 5, but this question is using
np > 10, so we'll use that. It means that the proportion times the sample size must be greater than 10, we have
80(0.1) = 8 and
80(0.9) = 72,
since we got 8 as one answer, the situation doesn't hold up.
The answer is 49=7x7 but it could be written as 49=7^2 too
Answer:
b > 9
Step-by-step explanation:
6(b – 4) > 30
Divide each side by 6
6/6(b – 4) > 30/6
b-4 > 5
Add 4 to each side
b-4+4 > 5+4
b > 9
