A triangle has vertices P(−5, 4), Q(3, 4), and R(−5, −2). S is the midpoint of Segment PQ and T is the midpoint of Segment PR. What is the length of Segment ST? Segment ST equals six square root of two end square root
Segment ST equals four
Segment ST equals three square root of two end square root
Segment ST equals five

Length of ST = mQR/2 = 4

Step-by-step explanation:

S and T are the mid-points of PQ and PR, so ST is parallel to and equal to half the length of QR.

(following corrected due to mistake)

Length of QR = sqrt((3--5)^2+(4--2)^2)=sqrt(8^2+6^2)=10

Length of ST = mQR/2 = 5

I apologize for the error previously committed.

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.
