What is the value of y in the equation 5x + 2y =20,when x = 0.3?

   5x + 2y = 20

5(0.3) + 2y = 20

   1.5 + 2y = 20

 - 1.5            - 1.5

            2y = 18.5

             2       2

              y = 9.25

The value of y  is 9.25.

(x, y) = (0.3, 9.25)

answer: you have to send a photo of the question

step-by-step explanation:

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.
