Answer:
x=0 y=-3
Step-by-step explanation:
28% of the marbles are green because there is a total of 25 marbles and 7/25 is 0.28. This translates to 28%.
Answer:
C. 5f +25
Step-by-step explanation:
If you have pick it, then you should be offered choices and you should include them in the question.
The answer is 3.09
We are given that 80% of scheduled flights really take
place, therefore this means that:
Probability of flying = 80% = 0.80
Now in statistics class, we know that the probability of
two or more independent events to occur is simply equivalent to the product of
their probabilities, or mathematically written as: (P = Probability)
total P = P1 * P2 * P3 *...
In this case, since we are to find for the probability
that 3 independent flights will occur, therefore the total probability assuming
equal probabilities to fly is:
total probability = 0.80 * 0.80* 0.80
total probability = 0.512
or
total probability = 51.20%
This means that there is only a 51.20% chance for 3
flights to occur.
