Example Question #172 : Statistics
In 2014 a professional sport drafted players out of college. About players were eligible for the draft. What percentage of eligible players were drafted?
To find the percentage of eligible players that were drafted we need to create a proportion.
Now we need to cross multiply and divide to solve the problem.
Example Question #173 : Statistics
To becomes president of the United States you must win one more than half the toital number of electoral votes (each state is alloted a certain number of votes based on population). There are votes available. What is the minimum number of electoral votes needed to win?
To find the minimum numer of votes needed to win we can set up the following equation.
Since we know our number of votes is 538 we get,
Example Question #174 : Statistics
A new donut shop is opening! As an introductory offer they are selling donuts for a dozen. John has . How many donuts can he buy?
To find out how many donuts John can buy we first need to see how many dozens he can buy with his $18.
To find this we use the following fraction,
.
From here we multiply each dozen by the number of donuts in a dozen which is 12.
.
Therefore, John can buy 72 donuts.
Example Question #175 : Statistics
Country A has the largest population on Earth, with billion people. Country B is next with billion people. How many more people does Country A have than Country B?
To find how many more people Country A has than B we need to subtract the number of people in Country B from that in Country A.
From here we will convert the units from billion to million.
0.3 billion is equivalent to 300,000,000
Example Question #171 : Calculations
The highest paid professional athlete in the US in 2014 earned about million over the games. About how much did he earn per game (in dollars)?

Example Question #172 : Calculations
In 2000 Richard bought a condo for . Ten years later he sold it for . How much did the condo appreciate (grow in value) per year on average (in dollars)?
To find the amount of growth the condo had per year we first need to find the amount of growht it had total. To find this we subtract the amount he paid from the amount he sold.
The condo grew in value.
Over 10 years that is per year.
Example Question #173 : Calculations
Cynthia made potato pancakes for Jeff. He loved them so much he ate them all in two days! How many potato pancakes did Jeff eat per day on average?
To find out how many pancakes Jeff ate on average we take the total number of pancakes he ate and divide it by the number of days he ate them.
The following fraction is our solution.
Example Question #174 : Calculations
Determine the range of the numbers:
The range is the difference of the largest and smallest numbers.
The largest number is 11.
The smallest number is negative nine.
Subtract both quantities.
The answer is:
Example Question #180 : Calculations
Use the following data set of test scores to answer the question:
Find the range.
To find the range of a data set, we will find the smallest and largest number within the set. Then, we will find the difference of those two numbers.
So, given the set
we can see the smallest number is 78 and the largest number is 95. Now, we will find the difference.
Therefore, the range of the data set of test scores is 17.
Example Question #1994 : Ged Math
A Science class took an exam. Here are the scores of 9 students:
Find the range.
To find the range of a data set, we will find the smallest and the largest number. Then, we will find the difference of those two numbers.
So, given the set
we can see the smallest number is 76 and the largest number is 93. Now, we will find the difference. We get
Therefore, the range of the data set is 17.
