Order from greatest to least -21 11 0 -5 -51/2

-51,-21,-5,0,11

Step-by-step explanation:

11,0,-5,-21,-51/2

Step-by-step explanation:

You just put them from greatest to least.

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.

78.59 is the mean
