Question

what is the mean of these numbers:3,5,7,9​

Answer 1

Answer: 6

Step-by-step explanation: The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set.

Let's begin by adding the numbers to get 24.

Now we divide 24 by the number of numbers in the set or 4.

So we have 24/4 which is 6.

Therefore, the mean of the data set is 6.

Answer 2

Answer:

Step 1: Define mean in math

In math, the mean is similar to the average. It is the sum of all of the numbers, divided by the number of values.

Step 2: Write equation

Now that we know how to find the mean, let’s write an equation accordingly. Add all of the numbers together, and then divide by 4, the number of values.

3+5+7+9/4

Step 3: Solve

For the final step, we need to solve the equation. Let’s begin by adding, and end by dividing.

3+5+7+9/4
24/4
6
