In a group of students, 20 students study Accounts, 20 study Mathematics, 17 study History, 7 study Accounts only, 10 study Mathematics only, 6 study Accounts and Mathematics only and 3 study Mathematics and History only. Represent the above information in the Venn diagram and find the total number of students in that group.​

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.

coins of silver or gold

step-by-step explanation:

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
