Jacob is reading a great thriller. the table shows a proportional relationship between the number of pages he reads and the number of hours he spends each week reading. what is the constant of proportionality in pages per hour?

14.

Step-by-step explanation:

2 hours = 28 pages = 2*14 pages

3 hours = 42 pages = 3* 14 pages

Then, the constant of proportionality in pages per hour is 14.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
