(add up all the data set and divide it by 7, why 7?, because there are about 7 numbers in the data set or the listed numbers)

2 + 3 + 5 + 7 + 8 + 8 + 9 = 49  

                                          ------ = 7

                                             7

(subtract the data set and 7)

7 - 2 = 5

7 - 3 = 4

7 - 5 = 2

7 - 7 = 0

7 - 8 = 1

7 - 8 = 1

7 - 9 = 2

(add the difference and divide it by 7 again)

5 + 4 + 2 + 0 + 1 + 1 + 2 = 15

                                         ------- = 2.14

                                           7

final answer would be 2.14

In △ RTV , X is the centroid and RU = 18. Find RX and XU. Enter your answers as numbers.
lapo4ka [179]

Answer:

RX = 12 and XU = 6

Step-by-step explanation:

Given :  In ΔTRV , TW ,RU and VS are the medians .

             X is the centroid

To Find : RX and XU

Solution:

Since we know that the centroid divides each median in a ratio of 2:1.



Since X is the centroid so RX : XU = 2:1

So, let RX = 2x and XU = x

And we are given that RU = 18

⇒RX +XU=18

⇒2x+x=18

⇒3x=18

⇒x=\frac{18}{3}

⇒x=6

Thus,  RX = 2x = 2*6 =12

          XU = x =6

Hence length of RX = 12 and XU = 6
