The 8 students in Mrs. Allen's class were asked how many minutes it takes them to get to school in the morning. Here is what they answered 4, 11, 15, 7, 11, 11,3,7
Find the mean and median travel times for these students.
If necessary, round your answers to the nearest tenth.

The mean is 8.6 and the median is 7

Step-by-step explanation:

The mean is found by adding the numbers and dividing the sum by the number of numbers in the list. So 4+11+15+7+11+11+3+7= 69/8=8.625 in the tenths place is 8.6. The median is the middle value in a list ordered from smallest to largest. So 3, 4, 7, 7, 11, 11, 11, 15, the meadian is 7 because it is the middle value.

Mean:

Median:11

Step-by-step explanation:

Median: 3 4 7 7 11 11 11 15 Middle number

Mean: 3+4+7+7+11+11+11+15=69 69/8 equals 8.625

8.625 to the nearest tenth ≈8.6

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:
