PLEASE HELP I WILL MARK BRAINLIEST

a) 53%

b) 12%

Step-by-step explanation:

you need to use the equation given

y = -6.83x + 108

x is the rank

y is the probability of winning 1st game

a) for rank 8th or x=8

y = -6.83(8) + 108 = 53.36 or 53%

b) for rank 14th or x=14

y = -6.83(14) + 108 = 12.38 or 12%

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.
