Mrs. Smith writes the following equation on the board. x
4 +
3
4
=
y
2
Choose the statement that is correct.
A
The equation is not linear because it has fractions.
B
The equation is not linear because it will not graph a straight line.
C
The equation is linear because it can be rewritten as
1
2
x +
6
4
= y.
D
The equation is linear because it has two variables.

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.
