Answer:
When a card is chosen at random with replacement five times, X is the number of times a prime number is chosen; When a card is chosen at random with replacement six times, X is the number of times a 3 is chosen.
Step-by-step explanation:
In a binomial distribution, there are only two outcomes, or outcomes that can be reduced to 2. In the first choice, we either draw a prime number or do not draw a prime number. In the third choice, we either draw a 3 or do not draw a 3.
There must be a fixed number of trials. In the first choice, we have 5 trials; in the third option, we have 6 trials.
The trials must be independent of each other. Since the cards in the first and third options are drawn with replacement, the outcome of one trial does not influence the probability of the next trial.
The probability must be the same for every trial. This is true of the first and third options.
Answer:
40º
Step-by-step explanation:
straight line: 180º
180-58-82=40
F(x)=(9+x)/(x³)
hmm
one way is to try increasingly small values of x that approachh 0
so like if x=0.1, we get a pretty big number
if x=0.00000000000001 we get an even bigger number
if x=-0.0000000001 we get a masivly small number
I conclude that as x approaches 0 from the left side, y approaches negative infintiy
as x approaches 0 from the right side, y approaches positive infintiy
does not exist
Answer:
201.42
Step-by-step explanation:
167.85 + 33.57 = 201.42
20% = 33.57
Answer:
=
Step-by-step explanation:
-|2 - 5| = -3, and 8 - 11 = -3
Therefore, - |2-5| = (8 - 11)
