The answer is D. When flipping a coin, the probability of getting tails does not change no matter how many times you flip the coin. It will always be 1/2.
Answer: ? = 72
Step-by-step explanation:
We will set up a proportion to solve.

Now, we will cross-multiply.
? * 35 = 56 * 45
35? = 2,520
? = 72
When you cannot simplify it further. The terms have no common factor besides 1 and A plus C does not have two numbers that multiply to the total and equal C.
<u><em>Answer:</em></u>
The height of the parallelogram is 33 ft
<u><em>Explanation:</em></u>
<u>The area of the parallelogram can be calculated using the following rule:</u>
Area of parallelogram = base * height
<u>In the problem, we are given that:</u>
Area = 544.5 ft²
Base = 16.5 ft
<u>Substitute with the given values in the above equation and solve for the height as follows:</u>
Area = base * height
544.5 = 16.5 * height

Hope this helps :)
Answer:
Both are rational.
Step-by-step explanation:
As a rational number can be written in the form p/q where p,q are co-prime integers, let a=p1/q1 b=p2/q2.
And we know the product of two integers is an integer
p1q2, p2q1 are integers. And the sum or difference of two integers is rational, rather being specific, it is an integer.
Thus a+b and a-b is rational.
