For an employee training, the employee to instructor ratio is 18 to 2. if there are 20 instructors for the training, how many employees participated in the training?

The ratio 18 to 2 can be divided by two to get a 9 to 1 ratio, so every every 1 instructor they can have 9 employees.

Multiply 9 by the number of instructors to get total:

20 * 9 = 180 employees.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
