the sum of two different numbers x and y is 70 and the differences when the smaller number is subtracted from the larger number is 30 what is the value of xy

1000

Step-by-step explanation:

Lets just say x is the bigger number. We can create two equations.

x + y = 70

x - y = 30

If we add these equations together, we get that:

2x = 100

and that

x=50

Plugging x back into any of the equations gets us that y = 20, so xy = 20*50 = 1000

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.
