The Jazz Band needs to raise at least $600 to travel to an upcoming competition. The members of the band have already raised $350. If they sell calendars for $8 each how many calendars would they need to sell to exceed their goal?

Step-by-step explanation:

250

step-by-step explanation:

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.
