Write the following quadratic expression in standard form: ( 2 x − 1 ) ( 3 x − 1 )

6 - 5 + 1

Step-by-step explanation:

Standard form is:

To reach that you have to distribute:

(2x - 1) (3x - 1)

2x (3x - 1) = 6 - 2

-1 (3x - 1) = -3 + 1

Combine like terms:

6 - 5 + 1

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.
