For this case we have that, by definition, the domain of a function is given by all the values for which the function is defined.
Having said that, we have the following function:
It is not defined when the denominator is equal to 0. That is:
Thus, the domain of r (x) is given by all real numbers except 1.
Answer:
all real numbers except 1.
Option A
Answer:
y = -6/7x + 16
Step-by-step explanation:
Use the slope intercept equation, y = mx + b
Plug in the slope and given point, then solve for b:
y = mx + b
4 = -6/7(14) + b
4 = -12 + b
16 = b
Plug in the slope and b into the equation:
y = mx + b
y = -6/7x + 16
So, the equation is y = -6/7x + 16

Answer: Choice C</h3>
P = 11/40 + 1/4 - 1/20
=========================================================
Explanation:
The formula we use is
P(A or B) = P(A) + P(B) - P(A and B)
In this case,
- P(A) = 22/80 = 11/40 = probability of picking someone from consumer education
- P(B) = 20/80 = 1/4 = probability of picking someone taking French
- P(A and B) = 4/80 = 1/20 = probability of picking someone taking both classes
So,
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 11/40 + 1/4 - 1/20
which is why choice C is the answer
----------------
Note: P(A and B) = 1/20 which is nonzero, so events A and B are not mutually exclusive.
