I don't think it really matters if the denominator is negative in a literal equation. Think about a simpler example with numbers. Does it matter whether a fraction is -1/2 or 1/-2? No, they are both the same. Therefore, I would say that the denominator of a literal equation can be negative.
Good luck with your exams!
The statement that is not true for goodness-of-fit tests is: A. Expected frequencies must be whole numbers.
<h3>What is Goodness-of-fit tests?</h3>
Goodness-of-fit tests can be defined as the test conducted to help find out whether the observe value work hand in hand with expected value or the observe value is different from the expected value.
The statement is not true because it is not must for expected frequencies to be whole number despite the fact that expected frequencies are whole numbers.
Therefore the statement that is not true for goodness-of-fit tests is: A. Expected frequencies must be whole numbers.

Angles in a triangle add up to 180 degrees
The value of x is 85 degrees
<h3>How to determine the value of x</h3>
The sum of angles in a triangle is 180 degrees.
So, we have:
x + 35 + 60 = 180
Evaluate the sum
x + 95= 180
Subtract 95 from both sides
x = 85
Hence, the value of x is 85 degrees

Answer: you will save with plan B for miles greater than 153.8 miles.
Step-by-step explanation:
Let x represent the number of miles driven with either plans per day.
Plan A: 30 dollars per day and 13 cents per mile. Converting cents to dollars, it becomes 13/100 = $0.13. It means that the total cost of driving x miles with plan A is
30 + 0.13x
Plan B: 50 dollars per day with free unlimited mileage. It means that the total cost of driving x miles with plan B is 50 dollars
For you to save money with plan B, it means that the number of miles would be
50 < 30 + 0.13x
50 - 30 < 0.13x
20 < 0.13x
0.13x > 20
x > 20/0.13
x > 153.8
