Answer:
47.5%
Step-by-step explanation:
Find the z-scores:
z = (x − μ) / σ
z₁ = (300 − 400) / 50 = -2
z₂ = (400 − 400) / 50 = 0
300 is 2 standard deviations below the mean, and 400 is 0 standard deviations from the mean.
From the empirical rule, 95% of a normal distribution is between -2 and +2 standard deviations. Since normal distributions are symmetrical, that means half of that is between -2 and 0 standard deviations.
95% / 2 = 47.5%

Answer:
A 8 hours
Step-by-step explanation:
Last week she baby sat 12 hours.
This week she baby sat x hours.
Last week she baby sat 1 1/2 times as many hours as this week.
12 = 1 1/2 × this week
12 = 1 1/2 × x
1.5x = 12
x = 12/1.5
x = 8

Answer: The required number of 
servings in a 12 cup container is 48.
Step-by-step explanation: We are given to find the number of servings in a 12 cup container.
We will be using the UNITARY method to solve the given problem.
We have
Number of 1 serving in a 12 cup container = 12.
Therefore, the number of servings in a 2 cup container is given by
Thus, the required number of servings in a 12 cup container is 48.
