Without drawing the graph of the function y=1.2x−7, see if the graph passes through points: ( 300; 353)

( 300; 353) is on the line y=1.2x−7

Step-by-step explanation:

y=1.2x−7

Substitute the point into the equation and see if it is true

353=1.2(300)−7

353 =360-7

353 = 353

This point is on the line

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.
