Step-by-step explanation:
Answer:
Question 1: 4/5 or %80
Question 2: 7/10 or %70
Step-by-step explanation:
<u>Step 1: Find the total amount of marbles</u>
5 + 2 + 3
<em>10</em>
<em />
<u>Step 2: Find the probability of not drawing a black marble</u>
Add the total amount of marbles that are not black
5 + 3
<em>8</em>
<em />
Now find the probability:
8/10
4/5 or %80
Answer: 4/5 or %80
<u>Step 3: Find the probability of not drawing a red marble</u>
Add the total amount of marbles that are not red
5 + 2
<em>7</em>
<em />
Now find the probability:
7/10 or %70
Answer: 7/10 or %70
- I’m assuming the expression implies the following:
(1-n)/(n^2 - 1)
The steps goes as follows:
= -(n-1)/(n^2-1) (factored a negative out)
= -(n-1)/[(n+1)(n-1)] (Factored denominator into a difference of squares, but don’t just blindly accept the fact, expand it and you should get the original denominator)
At this point, the (n-1) terms cancel, as you should know: a real number, besides 0, over itself is 1.
= -1/(n+1) , which is the answer
Note: You could also see it as 1/-(n+1) or 1/(-n-1)
X=2.3
You add 6.5 to both sides and get the answer X equals 2.3 :)
