Step-by-step explanation:
Divide 4.5 by 3 = 1.5
1.5 x 3 = 4.5
Answer:
We have a binomial probability distribution, in which:
P(X = 0) = 0.064
P(X = 1) = 0.288
P(X = 2) = 0.432
P(X = 3) = 0.216
Step-by-step explanation:
For each flight, there are only two possible outcomes. Either it is for domestic travel, or it is for international travel. Flights are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Let x be the number of requests among the next three requests received that are for domestic flights.
3 flights, and 60% are for domestic travel. This means that . The probabilities are given by:
Answer: 14.8units²
Step-by-step explanation:
The formula for calculate the area of a triangle is:
Where b () is the base and h () is the height.
The formula for calculate the area of a semicircle is:
Where r is the radius.
As you can see, the diameter is 5 units, then the radius is:
The area of the figure is the sum of the area of the triangle and the area of the semicircle.
Then, the result is:
