Determine the mean of the data. Round to the nearest tenth. 6, 9, 15, 22, 30, 36

pshichka [43]

To find the mean you add all the numbers and divide it by the amount of numbers there is so add
6+9+15+22+30+36=118
there is 6 number so divide 118 by 6
118/6=19.6666666667 rounded to the nearest tenth it would be 20
So your mean would be 20
let me know if you have any questions

Musya8 [376]

Answer:

$m=\frac{15}{8}$

Step-by-step explanation:

$-6\left(1-m\right)=9-2m$

$-6(1-m)=-6+6m$

$-6+6m=9-2m$

Add 6 to both sides:-

$-6+6m+6=9-2m+6$

$6m=-2m+15$

Now, add 2m to both sides:-

$6m+2m=-2m+15+2m$

Divide both sides by 8:-

$\frac{8m}{8}=\frac{15}{8}$

$m=\frac{15}{8}$
