Answer:
Since P(0) and P(1) have not the same values for the probability, X is not a discrete uniform random variable.
Step-by-step explanation:
Probability of data to be correct: 0.5
Probability of data being incorrect: 0.5
The random variable X is the number of fields that have an error within the range of 28.
P(0) =
P(1) =
To find the area of a regular polygon, area = 1/2 x perimeter x apothem.
Perimeter = the sum of the lengths of all the sides.
Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.
Answer:
3rd option
Step-by-step explanation:
There are three wholes and 1 fourth which is 1/8 simplified so first improper fraction, CHECK!
The three wholes are all equal to 12 then there is another 1 fourth so 12+1=13 CHECK TOO!!!
(YAY WE SOLVED IT!)
Answer:
sepalacola
Step-by-step explanation:
The exponential distribution is:
where
The probability we want is how likely will a dvd player last more than 8 years, given it has already lasted 5 years
To find this, you use conditional probability.
where A is P(x>8) and B is P(x>5)
To find these probabilities, integrate over the distribution:
Sub into conditional probability formula:
Final Answer: Given a dvd player is more than 5 years old, the probability that it will last another 3 more years is about 54.9%
