Answer:

Step-by-step explanation:
A quadratic equation in one variable given by the general expression:

Where:

The roots of this equation can be found using the quadratic formula, which is given by:

So:

As you can see, in this case:

Using the quadratic formula:

Therefore, the answer is:

Answer:
Step-by-step explanation:
The probability of drawing a red card is 1/2, since half of the cards in a deck are red. The probability of drawing an ace from a deck is 1/13, since there is an equal chance to pick any of the 13 numbers.
P(red card and ace)= P(red card)*P(ace)=1/2 * 1/13=1/26
This would be 525 / 0.70 = $750 Answer
