What is the range of data? a- 40 b- 42 c- 54 d-96 what is the median of data? a- 64.5 b-72.5 c-74.5 d- 75 what is the mode of data? a-5 b-70 c-75 d-88 (all these go with the stem-and-leaf plot)

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
