The mathematics faculty at a college consists of 11 professors, 7 associate professors, 8 assistant professors, and 12 instructors. if one faculty member is randomly selected, find the probability of choosing a professor or an instructor.

Approx. 61%

Step-by-step explanation:

There's 38 faculty members in total. 23 of them are either professors or instructors (I just added 11 and 12).

So 23/38 members are one of the two. In terms of percentage (which can be found by dividing 23 by 38 and multiplying by 100), you have about a 61% chance.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
