Answer:
Number of people who had been to Canada and Mexico both are 68.
Step-by-step explanation:
Mariah surveyed 200 people.
- She found 60% of the surveyed people had been to Canada.
That means number of people had been to Canada = 200 × 20%
= 200×
= 120
- She found 42% of the surveyed people had been to Mexico.
That means number of people had been to Mexico = 200 × 42%
= 200×
= 84
It is given that people who never been to Canada = 16
So the people who had been to Mexico only = 16
Since number of people who had been to Mexico = 84
So number of people who had been to Canada and Mexico both = 84 - 16 = 68
Number of people who had been to Canada only = Number of people who never had been to Mexico
= Number of people had been to Canada - Number of people who had been to both Mexico and Canada
= 120 - 68
= 52

Answer:
x ≠ 3
Step-by-step explanation:
The denominator of ...
f(x) = (x+2)/(x -3)
is zero when x=3, so the function is not defined there. Values of x for which the function is not defined are not part of the domain.
The restriction is: x ≠ 3.

Please note that parentheses are required around numerators and denominators when a rational function is written in plain text. When it is typeset:
the division bar serves as a grouping symbol. In plain text, we cannot tell where numerator and denominator begin and end unless some other grouping symbol (parentheses) is used.
