Example Question #226 : Algebra Ii
In order to pass Algebra II, Paul needs to have an average of 85 or higher for his final grade. On his three earlier tests, Paul scored a 95, 72, and 85. What is the lowest score that Paul can get on his last test to be able to pass the test?
Not enough information to determine.
We already know three of Paul's test scores and need to find the score on his last test so that the average is an 85.
Example Question #34 : Mean
Find the mean of the following number set:
Find the mean of the following number set:
To find the mean, simply take the sum of the number set and divide the sum by the total number of entries in the data set.
In this case, we get the sum via:
Then, because there are 7 entries in our set, we do the following
So our mean is
Example Question #227 : Algebra Ii
Find the mean of the following data set.
To find the mean of a set of numbers, simply sum the set of numbers and divide by the number of numbers in the set. There are four numbers in the set.
The mean is:
Example Question #36 : Mean
Find the mean.
To find the mean, add the fractions and divide by the number of numbers in the set.
The least common denominator is 12 because each fraction denominator can be converted to this value. Reconvert the fractions.
Add the fractions.
Divide this by three. This is the same as multiplying by one-third.
