Consider the following graph, which details one bookstore’s sales over the course of one day, divided by genre.

A graph titled Book Sales by Genre has genre on the x-axis and Number sold on the y-axis. Romance, 52; horror, 55; Fantasy, 60; Biograph, 57; Humor, 58; Cookbook, 54.

By percent, how much greater do sales of horror books appear to be than sales of cookbooks? How much greater are they in reality?

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

Given that:

Genre number sold

Romance 52
Horror 55
Fantasy 60
Biography 57
Humor 58
Cookbook 54

Let we have:
Number of horror books sold = P% greater than number of cookbooks sold

55 = P% greater than 54

55 = 54 + P% of 54

1 = P% of 54

[tex]1 = \dfrac{P}{100} \times 54\\\\P = \dfrac{100}{54} \approx 1.85[/tex]

Thus, the percent by which the sales of horror books is greater than sales of cookbook is 1.85% approx.

Between the theoretical probability that you will draw a blue tile and the experimental probability that you will draw a blue tile, which is greater, and how much greater is it? Express all probabilities as percentages to two decimal places, and express differences by number of percentage points (for example, 12% is 2 percentage points greater than 10%).

a.

The theoretical probability is 2.78 percentage points greater than the experimental probability.

b.

The theoretical probability is 1.49 percentage points greater than the experimental probability.

c.

The experimental probability is 4.06 percentage points greater than the theoretical probability.

d.

The experimental probability is 2.17 percentage points greater than the theoretical probability. <<<CORRECT
