There are 18 mathematics majors and 325 computer science majors at a college. a. in how many ways can two representatives be picked so that one is a mathematics major and the other is a computer science major? b. in how many ways can one representative be picked who is either a mathematics major or a computer science major?

Step-by-step explanation:

Given

There are 18 Mathematics Majors and 325 computer science majors at a college

(A)Two Representative to be selected

no of ways in which 1 representative of Mathematics major can be selected is

no of ways in which 1 representative of Computer science major can be selected is

Total no of ways

(b)No of ways in which either a Mathematics or computer science major can be selected is

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
