4) A spinner has the numbers 1 - 12. What is the probability of spinning a
number greater than 7?*

42%

Step-by-step explanation:

12-7 = 5

5/12 = .416

5/12

Step-by-step explanation:

since there are 5 values that are possible that are greater than 7 (8.9.10.11.12) you can take that number and divide by the total number of outcomes. so 5/12 is the probability that you will get a number greater than 7.

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.
