A jacket costs $90 at full price. It is on sale for 30% off the regular price. What is the amount of the discount?

1 answer:

5 0

Remember that when you find 30% of the number you have to subtract the 30% from your original $90 because it is 30% off the original price.

<h3>Answer: 9/38</h3>

Reason:

There are 10 red cards out of 10+10 = 20 total.

10/20 = 1/2 is the probability of selecting a red card.

If the red card is not put back (i.e. "no replacement"), then the chances of getting another red card is (10-1)/(20-1) = 9/19

Multiply the two fractions mentioned to get the final answer.

(1/2)*(9/19) = (1*9)/(2*19) = 9/38

We know that:

$\cos(2x)=1-2\sin^2(x)$

Here $x=3\theta$ so:

$1-2\sin^2(3\theta)=\cos(2\cdot3\theta)=\cos(6\theta)$
