Identify the kind of sample that is described. a sports columnist makes a list of email addresses of registered readers. he generates 150 random numbers and samples the email addresses on his list that correspond to these numbers about the potential basketball lockout. the sample is .

simple random sample

Step-by-step explanation:

The sport columnist generated 150 random numbers and sampled the numbers corresponding to each number of the email list to make sure that there is no bias as all of the email serial numbers have equal chance of being chosen. The sample he got is a  simple random sample.

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.
