Answer:
2.28% of faculty members work more than 58.6 hours a week.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The average full-time faculty member in a college works an average of 53 hours per week. Standard deviation of 2.8 hours.
This means that 
What percentage of faculty members work more than 58.6 hours a week?
The proportion is 1 subtracted by the p-value of Z when X = 58.6. So



has a p-value of 0.9772
1 - 0.9772 = 0.0228
0.0228*100% = 2.28%
2.28% of faculty members work more than 58.6 hours a week.
Answer: 41%
Step-by-step explanation:
Youe need to find the perecent of 14 out of 34
We know that 34 represents the whole so its 100%
Now we just multiply 100 times 14 which is 1,400
and now we divide it by our whole which is 34
you will get 41.1764
Just round it and you are done
2 hoses together:
15 mins = 1 pond
1 min = 1/15 pond
1st hose:
24 mins = 1 pond
1 min = 1/24 pond
2nd hose:
1 min = 1/15 - 1/24 = 1/40 pond
So 1/40 of the pond = 1 min
40/40 of the pond = 1 x 40 mins
1 whole pond = 40 mins
---------------------------------------------------------------------------------------------------
Answer: it will take 40 mins for the 2nd hose to fill up the pond alone.
