TiME liMIt HEL: There are 8 boys and 6 girls in a class. 3 boys
and 3 girls out of the class are going on a picnic.
The others are going on an education tour.

A. In how many different ways can the
picnic team be formed?

B. In how many different ways can the
education tour team be formed?

Step-by-step explanation

There are 8 boys and 6 girls and you have to choose 3 of each to go on the picnic. You can do this by doing: 8C3 x 6C3. This equal 56 x 20. So the answer to PART A: 1120 WAYS THE PICNIC TEAM CAN BE FORMED, PART B: 1120 WAYS THE EDUCATION TOUR CAN BE FORMED

this is because if you already choose the picnic team, then the rest of the kids just go to the tour, so the answer is the same for both (1120 ways)

the thermometer is precise but not accurate

step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
