Timothy runs a catering service for large parties. He needs 37 heads of lettuce for salad to feed 100 guests.

Which of the following ratios illustrates how many heads of lettuce, x, he would need to feed 275 guests?

100/275=x/37
x/100=37/275
37/100=x/275
100/37=x/275

100/275=x/37

Step-by-step explanation:

37 heads for 100 guests that means the ratio is 37/100

To calculate how many is needed for 275 guests we should to multiply 275 by 37 and divide it by 100

And the expression for it is 100/275 = x/37

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.
