Here's a question: mark has 20 cans of pepsi. if each can is 150 calories, will he gain a pound? ?

No because there are 3500 calories in a pound and 150 times 20 is 3000 calories.

No! because 1 pond contains 3500 calories

and 20 times 150 is 3000 so he need 50 more calories to gain a pound!

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

1/800 is the right answer
