Answer:
area = x(3x +10)
Step-by-step explanation:
The lengths of the unmarked sides are found as the difference between the lengths of the parallel marked sides.
horizontal unmarked = (2x+15) -x = x +15
vertical unmarked = (2x -5) -(x -5) = x
The area of the figure is the sum of the areas of parts of the figure. The area can be divided several ways. One is shown in the attachment, along with the areas of the parts and of the whole.
The whole area is ...
x(2x -5) +x(x +15) = x((2x -5) +(x +15)) = x(2x -5 +x +15) = x(3x +10)

Answer:
f || m
Step-by-step explanation:
If f is parallel to k and k is parallel to m
then f must be parallel to m

Step-by-step explanation:
n + n+1 + n + 2 = 45
3n + 3 = 45
3n = 42
n = 14

Answer:
Explanation:
This is a typical problem of conditional probability.
In this case you know:
- the probability of the event D <em>(an international flight leaving the U.S. is delayed in departing</em>), which is 0.36 and you can write as P(D) = 0.36
- the probability of event P <em>(an international flight leaving the U.S. is a transpacific flight</em>), which is 0.25 and you can write as P(P) = 0.25;
- the joint probability of event P and D (<em>international flight leaving the U.S. is a transpacific and is delayed in departing</em>), which is 0.09 and you can write as P (P ∩ D) = 0.09.
You need to determine the <em>probability that an international flight leaving the United States is delayed given that the flight is a transpacific flight</em>, i.e. the conditional probability P (D/P).
Hence, use the formula for conditional probability:
- P (D/P) = P (D ∩ P) / P(D) = P (P ∩ D) / P (D)
- P (D/P) = 0.09 / 0.25 = 0.36
