Step-by-step explanation:
You didn't give the box plot, but to obtain the percentage of people between 20 and 37 years old, first of all, find the total number of people, T. Next, find the total number of people between 20 and 37 years old, t.
Then the percentage we want to find is:
P = T/t × 100
The answer to b is 24×600=14400
24=hours in a day
600=blooded pumped per hour
14400=the amount the blood is pumped a day
How many friends are their without the number of friends you cant answer it so the answer is unknown
