Answer: 
Step-by-step explanation:
Total number of cards in a deck = 52
Number of red cards = 26
Number of cards not red =
Number of ways to draw not red cards = 
Total ways to draw 3 cards = 
The probability that none of three cards are red = 
[∵ 
]
Now , the probability that at least one of the cards drawn is a red card = 1- Probability that none cards are red
Hence, the required probability =
The total revenue of the function is the product of the quantity and the price
The total revenue in terms of P is TR = 20P - 0.01P^2
<h3>How to determine the total revenue?</h3>
The demand and the cost functions are given as:
Quantity function, Q = 20 - 0.01P
Cost function, C(Q)=60+6Q
The total revenue is calculated as:
TR = Q * P
Substitute Q = 20 - 0.01P in the above equation
TR = P * [20 - 0.01P]
Evaluate the product
TR = 20P - 0.01P^2
Hence, the total revenue in terms of P is TR = 20P - 0.01P^2

C=(5/9)*(40-32) = (5/9)*8 = 40/9 = 4 4/9
So the right answer is C.
Answer:
True.
Step-by-step explanation:
The answer is true. All you need is one 90 degree angle, two 50 degree angles, and one 170 degree angle. This creates a weird looking shape that is a quadrilateral with no parallel lines and at least one right angle.
