Find a number that you can make 10,100,or any 1 followed by zeroes
then,multiply both numerator and deno with that number
Then write down just the top number, putting the decimal point in the correct spot (one space
from the right hand side for every zero in the bottom number)
15.5% is the same as 15.5/100 or 155/1000, which you can take a 5 out of.
After that, you will get 31/200
Answer: The correct answer is the third choice.
Step-by-step explanation: The question is asking you to look at pieces of data from the graph. The best way to do this question is to look at each question to determine whether the statement is true or false.
In looking at the each choice:
First one - The statement is true. Looking at the graph, a 40 and 50 year old person has the same average rate.
Second - The statement is true. Looking at the graph, you can see a steady decline from a 10 year old to a 20 year old person.
Third - The statement is false. A 10 year old and 20 year old do not have the same rate.
Fourth - The statement is true. A 20 and 30 year old have the same heart rate.
