The probability is 0.9958.
We first find the z-score associated with both of these values, using the formula
.
For the lower score, we have:
Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of, less than, this is 0.0021.
For the upper score, we have:
Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of, less than, this is 0.9979.
To find the area between these two, we subtract:
0.9979 - 0.0021 = 0.9958

Answer:
25 months
Step-by-step explanation:
Big Gym Fitness charges $22 per month for a membership.
After x months, the charges will be:
22 * x = 22x
All-Day Fitness charges $20 per month plus $50 membership fee.
The membership fee is a one time payment. Hence, after x months, the charges will be:
50 + 20*x = 50 + 20x
After a certain number of months (x months) , the two fitness clubs will have the same charges. This occurs when:
22x = 50 + 20x
Hence, solving for x:
22x - 20x = 50
2x = 50
x = 50 / 2 = 25 months.
Their charges will be the same after 25 months.
