Answer:
An acute angle is an angle less than 90°
Answer:
There will be 8 possible outcomes.
Step-by-step explanation:
(Assume that there is no other outcome such as "no opinion" and "do not know.")
3 persons are selected at random from this group and their opinions in favor or against raising such taxes are noted.
So, the number of possible outcomes are = 
YYY, YYN, YNY, NYY, YNN, NNY, NYN, NNN
Y = Yes and N = No
Therefore, there will be 8 possible outcomes.
The equation can still be solved but it should be stated clearly at what value of would the equation be undefined. For instance, you have an expression,
1/x+2
When x is equal to -2, the denominator will be 0 resulting to an undefined solution. The value of x here can be any real number except -2.
If you estimate, its around 5
