Answer:
25.5 days
Step-by-step explanation:
Mean number of days (μ) = 22 days
Standard deviation (σ) = 6 days
Z-score for the 72nd percentile (according to tabulated values) = 0.583
The z-score for any number of days, X, is determined by:

The value of X that is greater than 72% of the trial times is:

Therefore, 72% of all of these types of trials are completed within 25.5 days.
Step-by-step explanation:
4
Add all to get 32
Divide by the number of items which is 8
answer =4
Answer:
h(t) = –16+48t
h(32)=-16+48(32)
h(32)=-16+ 1536
h(32)= 1520seconds
Step-by-step explanation:
