A student conducts a survey on the eye color of a group of ninth-graders and then randomly selects a ninth-grader. Compare the experimental probability of choosing a ninth-grader with blue eyes to the experimental probability of choosing a ninth-grader with hazel eyes.

Eye Color Blue Brown Green Hazel
Number 37 62 13 15

75

Step-by-step explanation:

blue : brown : green : hazel

37    :     62    :    13      :   15

37 + 62 + 13 + 15 = 127

hazel (15 ) + blue (37) = 52

127 - 52 = 75

The probability is 75/ 127

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:

gimmee one of those gold crowns!
