Less than 3 is about 10.75% and greater than 13 is about 6.18%.

To find these percents, you need to find the z-score for each value. Then, use your table to find the correct percent. Be sure to find the side above 13 when you use your chart.

For less than 3:
(3 - 7.45) / 3.6 = -1.24 = The percent below this is 0.1075

For greater than 13:
(13 - 7.45) / 3.6 = 1.54 = The percent above this is 0.0618

One company estimates same-day delivery as more than three less than half the total number of miles. Which graph represents the
VMariaS [17]

By using an online graphing calculator, the overall equation represented by this scenario is plotted in the image attached below.

<h3>How to determine the graph?</h3>

Based on the information provided about this company with respect to its delivery and total number of miles to be covered, we would assign variables as follows:

  • Let y represent same-day delivery.
  • Let x be the total number of miles.

Next, we would translate the word problem into an algebraic equation by using an inequality:

y > x/2 - 3

Also, we would determine the intercepts as follows:

When x = 0, we have;

y = 0/2 - 3

y = -3.

y-intercept = (0, -3).

For the x-intercept, we have:

When y = 0, we have;

0 = x/2 - 3

x/2 = 3

x = 6.

x-intercept = (6, 0).

By using an online graphing calculator, the overall equation represented by this scenario is plotted in the image attached below.
