Find the mean of the following data set:

To find the mean, sum up your terms and divide by the number of terms.

We have 11 terms, so that will be our numerator.

Recall how to find the mean:

Start by finding the sum of all the values given:

Since we have six months, the number of values is .

Now, find the mean:

To find the median, start by placing the values in numerical order:

The middle term, or the median, of this set is .

Next, recall how to find the mean of a set of values:

Thus, the mean for this set of values is

The difference between the median and the mean is then

Recall how to find the mean:

The question gives us the mean and the number of values. Let  be the number of pounds that must be harvested on the eighth day, and then we can write the following equation and solve:

 pounds must be harvested on the eighth day in order for the average pounds of strawberries harvested to increase the desired amount.

Recall how to find the average of a set of numbers:

We can then set up the following equation. Let  be the score of the fifth test.

Solve for .

Joseph must score a  on his next test to pass the class.

The average distance Peter ran over five days is the sum of the distances he ran divided by five, so first, add the distances:

Rewrite the expressions in terms of halves, and add numerators:

Peter ran a total of six miles. Since we are asked for an answer in feet, first, multiply this by 5,280 feet per mile:

feet.

Now, divide by 5:

feet per day, the correct response.

To find the mean, you must first add up all of the numbers in the set, then divide the total by how many numbers you have.

Let's start by adding up all the whole set.

Not counting the total, we see that we have  numbers in our set. We will divide  by  in order to get the mean.

Our answer is .

To find the mean, we must add up all of the numbers in our set, then divide our total by how many numbers we have.

Let's first add up the set. Remember to include the negative when adding.

If we count all of our numbers, not including the total, we can see that we have  numbers. Now we shall divide  from .

Our answer is .

To find the mean, we must first add up all of the numbers in our set, then divide the total by the number of numbers in our set.

Let's first add up all of our numbers.

Not including the total, we can see that we have  numbers in our set. We will divide  by  in order to get the mean.

Our answer is .

In order to find the mean, we must first add up all of the numbers in the set, then divide the total number by how many numbers we have.

If you have a calculator, then adding these fractions should be easy. If you don't have a calculator, then we will add them up by hand.

Right now we can't add our fractions together, as they have no common denominator. We must convert all of these fractions to have the same denominator and then we can add them.

 is a number that can have , , and  in it, so we will use this number as our denominator. So we will multiply  by ,  with , and  with  in order to have  as the denominator. Make sure to multiply the numerator too!

Since we have  fractions, we will divide  by . This is the same as saying we are multiplying it by .

Our answer is
