Answer:
mean = 160
Variance = 156.8
Standard deviation = 12.52
Step-by-step explanation:
This is solved by the binomial distribution model for approximation.
n = number of random sample in which for this question, n= 8000
p = probability of success = 2% = 0.02
Mean of the sample = Expected value which approximates the average number of cases to expect from the larger sample chosen.
Mean = np = 0.02 × 8000 = 160
Variance = np(1-p) = 160(1-0.02) = 156.8
Standard deviation = √variance = √156.8 =12.52

It is 1 over 8 aka 1/8. hope it helped.
Answer:
z > -2
Step-by-step explanation:
7 + z > 5
subtract 7 from each side of the equation:
z > -2
1. 9.86* 10 ^13
2. 5.394* 10^13
3. and 4. I don't know those questions are confusing
5. 2.3705* 10^35
6. 5^10
7. 4^13
8. 6^ 36
9. 2.425674* 10^30
10. 1.1556* 10^13
