The following two-way table shows the number of students of a school who have a video game and/or have a laptop:
have video game do not have video game total
have laptop
15
50
65
do not have laptop
50
15
65
total
65
65
130
based on the table, how many students have both a laptop and a video game?
15
50
65
130

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.
