Answer: 50 calories
Step-by-step explanation:
One serving of a certain brand of microwave popcorn provides 150 calories, 90 of which are from fat. The fraction that comes from fat:
= 90/150 = 3/5
One serving of a certain brand of low-sodium pretzels provides 120 calories, 12 of which are from fat. The fraction that comes from fat here:
= 12/120 = 1/10
The fat that are provided by a 100 calorie serving of the microwave popcorn would be:
= 3/5 × 100
= 60
The fat that are provided by a 100-calorie serving of the pretzels would be:
= 1/10 × 100 = 10
The difference from fat that are provided by a 100 calorie serving of the microwave popcorn than are provided by a 100-calorie serving of the pretzels would be:
= 60 - 10
= 50 calories
To find the Mean or Average you have to add up all numbers it is asking for which in case are 222 and 198.
so you will add 222+198
That will equal 420
Then you will divide with the amount added together which is 2
420/2=210
so the mean of the 11 people is 210 or 210lbs

1 + 2 + 3 + 4 + 5 + 6 + 7 = 28
28/7 = 4
Median: Middle number
1,2,3,4,5,6,7
