A student solved the equation x+2(x+1)=17 below and showed their work in the table below. Problem x+2(x+1)=17
Line 1 x+2x+2=17
Line 2 3x+2=17
Line 3 3x=15
Line 4 x=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.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

answer: the answer is b. i think hope i got it correct
