Answer: can't add an answer, but for the first all 3 angles add up to 180 in a triangle for the second, plug 5 in and also check if all three add up to 180
Step-by-step explanation:
Answer: all of the above
Step-by-step explanation:
|3k - 2| = 2|k + 2|
3k - 2 = 2|k + 2| or 3k - 2 = -2|k + 2|
(3k - 2)/2 = |k + 2| or (3k - 2)/-2 = |k + 2|
(3k - 2)/2 = k + 2 or -(3k - 2)/2 = k + 2 or -(3k - 2)/2 = k + 2 or (3k - 2)/2 = k + 2
3k - 2 = 2(k + 2) or -3k + 2 = 2(k + 2)
3k - 2 = 2k + 4 or -3k + 2 = 2k + 4
3k - 2k = 4 + 2 or 2k + 3k = 2 - 4
k = 6 or 5k = -2
k = 6 or k = -2/5
To do this problem, 30 divided by 150 then multiplied for 100.
We could get 20%
Answer:
The probability that the airline books 23 people is 0.024. We can consider that overbooking is something unlikely to occur.
Step-by-step explanation:
This is binomial experiment so we can use the probability fuction of a binomial distribution:
P(x)=
·pˣ·(1-p)ⁿ⁻ˣ
whrere:
p: is the probability of a passenger arrive for the flight (0.85)
n: number of experiments
Hence;
P(x=23)=
·(0.85)²³·(1-0.85)²³⁻²³
P(x=23)=(0.85)²³=0.024
