Answer:
At least 37.74% of the procedures takes between 97.6 and 125.6 minutes
Step-by-step explanation:
The percentage is the area of the standard normal distribution curve between the values 97.6 and 125.6
The standard normal variate of the given data is found as
Thus for the given values Z is calculated as under
Similarly for the other value we have
Thus the area between the calculated values can be found from standard normal distribution table to be 37.74%
Answer:
904.32 cubic ft
Step-by-step explanation:
To find the volume of a sphere, the formula is
First, 3.14 * 4 for 12.56.
The radius is 6, and that cubed is 216.
After that, divide 216 by 3 for 72
Then, 12.56 times 72, which gets you the final answer of 904.32 cubic ft.
(10 * 72) + (2 * 72) + (0.5 * 72) + (0.06 * 72)
720 + 144 = 864
864 + 36 = 900
900 + 4.32 = 904.32
Answer:
d. It is at most 25 percent.
Step-by-step explanation:
According to Chebyshev's inequality, for a given number of standard deviations, k, no more than 1/k² can be more than k standard deviations from the mean. In this situation the amount of standard deviations from the mean of the upper and lower bound of salaries are:
For k = 2, applying Chebyshev's inequality:
Therefore, at most 25% of the salaries are less than $68,000 or more than $92,000.
