Answer: 2 1/3 feet
Step-by-step explanation:
3.5 / 1.5 = 2 1/3
Using the Empirical Rule, it is found that 95% of the employees will have a travel time within the following range:
B. 8 minutes to 28 minutes.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Considering that the mean time is 18 minutes and the standard deviation is 5 minutes, the the bounds of the 95% range are given by:
Hence option B is correct.

Answer:
f(1) = 4
Step-by-step explanation:
f(1) means let x=1 and find the y value at that point on the graph
At x=1 there is an open circle and a closed circle. The open circle means that the function does not have a value at that point, so we use the closed circle
f(1) = 4
