Asalesperson obtained a systematic sample of size 25 from a list of 500 clients. to do so, he randomly selected a number from 1 to 20, obtaining the number 13. he included in the sample the 13th client on the list and every 20th client thereafter. list the numbers that correspond to the 25 clients selected.
a.. 25,
b. 20, 332
c. 13, 33, , 488
d. 13, 33, 493

Option 'D' is correct.

Step-by-step explanation:

Since we have given that

First term = 13

Increase each time = 20

Number of clients = 25

So, it forms an arithmetic progression:

So, 25 th term would be

Hence, list would look like 13,33,............493.

Therefore, Option 'D' is correct.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
