49. given f(x) =2x^2+5 and g(x) =3x^3, what is f(x)x g(x)? a. 2x^2 + 15x^3 b. 6x^6 + 15x^3 c. 6x^5 + 15x^3 d. 3x^3 + 2x^2 + 5

Hello from MrBillDoesMath!

  C

Steps:

(2x^2 + 5)(3x^3) =    

(2x^2)(3x^3) + 5(3x^3) =

6 x^5            + 15x^3

Which is choice C

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.
