There are three 'x's on the 3/4 spot, so you know that there are three 3/4 inch buttons.

To find how long they are lined up, you add them.

3/4 + 3/4 + 3/4 = 9/4

9/4 as a mixed number is 2 1/4.

Good luck!

Here are the step for solving this:
1. 3y + 5 > 23
-5 -5
3y/3 > 18/3
y > 6

In words what you are doing is getting y by itself on one side. Subtract the 5 to undo the adding of 5 first. Then, divide both sides by 3.

If you were given the data set $s $10, $10, $12, $13, $15, which measure of central

Katarina [22]

Answer: Mode

<u>Step-by-step explanation:</u>

The given data set is: 10, 10, 12, 13, 15

Mean is the average - find the sum of the data set and divide by the number of terms in the set: $\dfrac{10+10+12+13+15}{5} =\dfrac{60}{5}=12$

Mean = 12

Median is the middle term (when the data set is ordered from least to greatest).

Median = 12

Mode is the term that appears the most.

Mode = 10

Since you want to show that the prices are low, you would choose the lowest value. 10 is lower than 12, so the Mode is lower than either the Mean or the Median.
