David is buying a new car. He can choose
from 11 car colors, 5 interior materials, and 7
safety features. How many different
combinations of cars could David order?
Enter the correct answer.

385 different combinations

Step-by-step explanation:

In order to find the number of different combinations when given the number of options, simply multiply all options together - almost as if you were solving for the volume of a rectangular prism.

For example, if I were given 3 different colors and 2 different interior materials, I would have 6 different combinations of cars, because 3x2 is 6.

In this case, 11x5x7 is 385!

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.
