If you would like to know how long will it take to drain the pool, you can calculate this using the following steps:
3 hours ... 250 gallons
x hours = ? ... 150 gallons (= 400 - 250)
3 * 150 = 250 * x
x = 3 * 150 / 250
x = 1.8 hours
3 hours + 1.8 hours = 4.8 hours
The correct result would be B. 4.8 hours.
Answer:
We are required to find the proportion of observations from a normal distribution that are greater than 1.36. Mathematically, it can be written as:

To find this proportion, we can use the standard normal table. Using the standard normal table, we have:

Therefore, the proportion of observations from a standard normal distribution that take values greater than 1.36 is 0.0869.
Answer:
36 minutes long
Step-by-step explanation:
6.82 = 2.5 + 0.12m
4.32 = 0.12m
