Solve for x<br><br> 2/7x = 6<br><br> (SHOW YOUR WORK)
castortr0y [4]

Answer:

The answer to your question is  x = 21

Step-by-step explanation:

Equation

                                       \frac{2}{7} x = 6

- Multiply both sides by 7

                                        \frac{(2)(7)x}{7} = 6(7)

- Simplify

                                        2x = 42

- Divide both sides by 2

                                         \frac{2x}{2} = \frac{42}{2}

- Simplify

                                         x = 21

What is the median of this data set?
bazaltina [42]

Answer:

14

Step-by-step explanation:

Because the median is the middle number when the data set is in order least to greatest so you already have it in least to greatest so thank you for helping me.

and for extra just in case.

Mean=16.222

the mean= the average of the data set

Mode is 13,14

The mode is the number that appears the most in a data set and 13 and 14 appear twice.

Your range is=13

Range is the highest number subtracting the lowest number so 24 -11 which =13

Minimum is 11 because the minimum is the lowest number in data set..

Maximum is 24

Maximum is the highest number in the data set.


I hope this helps have a awesome day:)
