HELP PLEASE I DONT GET THIS THANKS

√10

Step-by-step explanation:

Pythagorean theorem. a^2+b^2=c^2.

In this case 9^2+b^2=√91^2. That equals 81+b^2=91. You isolate b^2, b^2=10. So b=√10.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
