Mr. Gomez decided to give a test worth 90 points and contains 25 questions multiple-choice questions are worth three points and Word problems are worth four points how many of each of these questions are there

the test has 10 multiple-choice questions and 15 Word problems questions.

Step-by-step explanation:

Let x represent the number of multiple-choice questions in the test.

Let y represent the number of Word problems questions in the test.

The total number of multiple-choice and Word problems questions in the test is 25. This means that

x + y = 25

The multiple-choice questions are worth three points and Word problems are worth four points. The test is worth a total of 90 points. This means that

3x + 4y = 90 - - - - - - - - - - -1

Substituting x = 25 - y into equation 1, it becomes

3(25 - y) + 4y = 90

75 - 3y + 4y = 90

- 3y + 4y = 90 - 75

y = 15

x = 25 - y = 25 - 15

x = 10

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%
