Email is an effective and professional method of communication, and it is important that college students check their email every day. Of interest in this project is to determine the level of the relationship between the number of emails received in a day and the total amount of time it took the student to read her emails. More specifically, we want to determine the correlation between the number of emails received in a day and the total amount of time it took the student to read her emails, and to use the number of emails to predict the total amount of time it takes the student to read her emails each day. Required:
One of the variables in the study is the number of emails received each day. What type of variable is this?

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%

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
