To simplify the expression (5x^2 - 21x - 20) / (5x^2 - 16x - 16), we can check if there are terms that are needed to be added or subtracted. In this case, there are none. We just check the factors of each polynomial above and below. The factored equation of the numerator is (x-5)*(x + 4/5) while that below is (x-4)* (x + 4/5). In this case, we cancel <span>(x + 4/5). Hence the answer is (x-5) / (x-4)</span>
Answer:
-23
Step-by-step explanation:
Common difference = 2nd term - 1 st term
= -8 - (-3)
= -8 + 3
= -5
To get the next term add (-5) to the previous term
5th term = (-18) + ( (-5) = -23
1/8, 1/4. 3/8, 1/2, 5/8, 3/4, 7/8 and 8/8 or 1 is the answer
P(B|A) means "the probability of B given A", which in turn means: how likely is B, if we are guaranteed that A is true?
In your case, this means: if you already know that the person has a sister, how likely it is that the same person also has a brother?
if you look the diagram, you see that 4 people has a sister: Davis, Kari, Chu, Evan. Out of these 4 people, 2 of them also have a brother.
This explains P(B|A)=0.5: half of the people with a sister also have a brother.
