We need to divide the number of inches by the number of hours.
Let's first convert the two numbers into fractions.
12 1/2 = 25/2
25 1/2 = 51/2
(25/2) / (51/2) = 25/2 * 2/51 = 50/102 = 25/51 = 0.49
The average rainfall was approximately 0.5 inches per hour.

Answer:
Step-by-step explanation:
Given that: Training-session duration of female rowers with normal iron status is Normally distributed, with mean 69 minutes and standard deviation 18minutes.
Solution:
z score shows the relationship between sample means. The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by the formula:

Given that μ = 69 minutes, σ = 18 minutes, n = 24
For x > 63 minutes:

From the distribution table, P(x > 63) = P(z > -1.63) = 1 - P(z < 1.63) = 1 - 0.0516 = 0.9484
