Solve of h and solve of k

9514 1404 393

  A)  h = 4

  B)  k = 6.5

Step-by-step explanation:

In each case, the midsegment is half the length of the parallel base segment.

A) FG = 2KJ

  (4h -8) = 2(h)

  2h = 8

  h = 4

__

B) GH = 2LK

  4h -3 = 2k

  (4(4) -3)/2 = k = 13/2 = 6.5

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

answer: 5100 just subtract
