1. It is extracted from the ground.
2. It took years to form.
The triangle was just flipped so the missing side is going to equal 36, so...
2y+20= 36
(Subtract 20 from each side to isolate the 2y)
2y= 16
(Divide each side by 2 to isolate the variable)
ANSWER:
y= 8
Answer:
The correct option is A. 198 degrees
Step-by-step explanation:
Consider the provided information.
87 percent of students worked at least sometime during their undergraduate career and 13 percent did not work at all.
Another question showed that 32 percent of the students worked throughout their undergraduate career.
87 percent of the students worked at least sometime during the college. Out of them 32% worked throughout the college.
Therefore, the students who worked sometime during their undergraduate career, but not throughout are:
(87-32)% = 55% .
As we know the angle measure in circle is 360 degrees.
55% of 360° is:
Hence, the measure of central angle would be 198 degrees
Therefore, the correct option is A. 198 degrees
Answer:
- <em>The probability that the second favorite character will die given that the first favorite character dies is</em><u> 0.53</u>
- <u>This kind of probability is called conditional probability</u>
Explanation:
Name the events and their probabiities:
- Event A: her favorite character will survive, so P (A) = 0.70
- Event B: her her second favorite character will die, so P(B) = 0.75
- Both characters will die ⇒ P (B and not A) = 0.16
You want to find P (B | not A).
That is the probability of the succes B (the second favorite character will die) given other event (not A or the first favorite character dies) is certain (it happens) and that is called conditional probability.
- P (not A) is the complement probability of A, so P (not A) = 1 - P(A) = 1 - 0.7 = 0.3
So, you have P(B), P(not A) and want to find P (B | not A)
The definition of conditional probability is:
- P (X | Y) = P (X and Y) / P (Y)
So, replacing with our terms, we get:
- P ( B | not A) = P (B and not A) / P (not A) = 0.16 / 0.3 ≈ 0.53
