Answer:
77.88 minutes
Step-by-step explanation:
Given that :
Mean (m) = 70
Standard deviation (s) = 10
For 80% of student to complete the exam. In the given time
Using the formula :
Zscore = (X - mean) / standard deviation
80th percentile = 80/100 = 0.8 has a Zscore = 0.7881
0.7881 = (X - 70) /10
0.7881 * 10 = X - 70
7.881 = X - 70
7.881 + 70 = X
77.881 = X
Hence, 77.88 minutes should be given
Simply add 5.5 feet to 1.5 feet. The answer is 7 feet below sea level.
The answer is 15.
30% of 60 = 18
45% of 60 = 27
27 + 18 = 45
60 - 45 = 15
This question shows you how to determine the amount of money Mr. Leonard makes in 4 weeks. It takes his total salary, divides it by 52 (there are 52 weeks in a year), then multiplies it by 4 (you need 4 weeks worth of pay).
This amount is shown as $6769.24.
He must pay the agency 22% of this, so change 22% to 0.22 and multiply it by the amount he makes in 4 weeks.
0.22 x 6769.24 = $1489.23
Mr. Leonard must pay the agency $1489.23 after the first 4 weeks.
