How do you know if they are outliers? to be an outlier an observation would have to be greater than or less than

You know if its a outlier if its no where near to rest of the numberrest

Step-by-step explanation:

for an example lets say teh data chart was 1 2 3 4 5 6 7 8 9 10 and the its 100 100 is obvi teh outlier because if it was on a graph it will be super far away

15

step-by-step explanation:

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.
