One bag is 5 1/4 pounds so you need to multiply that by 1 1/2 or 3/2 as an improper fraction
21/4 x 3/2 =63/8 change that to a proper fraction to get 7 7/8 lbs
Answer:
-3/4 ÷ 2/-8 = 3 ( i think so! )
Answer:
There are 253 ways to select 5 participants
Step-by-step explanation:
Total number of volunteers to try a new brand of tennis shoes = 10
Number of volunteers to be selected = 5
We are supposed to find number of ways the research group select 5 participants.
We will use combination:
Formula:
Substitute n = 10 and r = 5
So,

Hence There are 253 ways to select 5 participants
