Answer:
Let's assign the variable x to cosA. The expression then becomes x² - 5x + 6. To factorize this we need to find two numbers that have a sum of -5 and a product of 6; these numbers are -2 and -3 so the expression becomes (x - 2)(x - 3). Since we know that x = cosA the final answer is (cosA - 2)(cosA - 3).
Let X be the random variable representing the number
of coins that Matt set aside after three flips.
We have to run n from 0 to 100 and m from 0 to (100-n),
Find the binomial law, then compute the mean like this:
Hope this gives a hint.

Hello! :p
Original: 8+3x=-9y
standard form: 3x + 9y = -8
I hope this helps! Have a wonderful day! :)
Answer:
Total cards in a deck=52
Face cards =12
So probability of picking a face card is 12/52=3/13
Step-by-step explanation:
Usually there are 12 face cards in a group, so that would be 12/52 -- but wait! You can simplify, always. check. for. simplifying. possibilities.
Usually in an answer they will include both simplified, and not simplified. Believe it or not, usually they ask for the simplified. Make sure you read carefully.
