Ibeg me anyone i bge pleass what is the d value of the following sequence? -6, -12, -18, -24,… 4 -6 -7 2 3 what are the next 2 terms in the following sequence? -1, -3, -5, -7,… -8, -10 -8, -9 9, 11 -9, -11 find s22 for -6 + (-4) + (-2) + 0 … 330 332 334 336 find s16 for 1 + 7 + 13 + 19 +… 760 754 742 736 <

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.

look a the sides they are perpendicular
