I need help the assignment is due in thirty minutes! multiply each side if 0.33x^2 + 0.7x-0.14=0 an appropriate power of ten to obtain integer coefficients

A 7/11, 2/3

B 7/11, -2/3

C. 12 7/11, 2/3

D. -2/3, 7/3

E. 2/11,-7/3

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.
