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).

Answer:
3/70
Step-by-step explanation:
3 orange,6 pink , 1 yellow , and 5 red = 15
P(pink) = number of pink/ total = 6/15 = 3/5
Then without putting it back
3 orange,5 pink , 1 yellow , and 5 red = 14
P(yellow) = number of yellow/ total = 1/14
P(pink, no replacement, yellow) = 3/5*1/14 = 3/70

Answer:
The first blank is: 26
The second blank is: 17
The third blank is: 31 - n
Step-by-step explanation:
So basically each row should add up to 31. So for every number they give you (doesn't matter which color ball), you need to subtract it from 31.
That's why for the first blank, 31 - 5 is 26
second blank, 31 - 14 is 17
and so on....
so the resulting function would be 31 - n
n being a random number that is given to you
