a) Number of seats expected to be empty = 18
b) Number of passengers expected to show up for the flight = 291
Step-by-step explanation:
Step 1:
Probability that a passenger will not show up for the flight = 6%
Total capacity of the flight when fully booked = 300
Step 2 :
a)
Number of seats expected to be empty = 6% of 300 = × 300 = 18
b)
Number of passengers over booked = 10
Probability that a passenger will turn up for a flight = 100 - 6% = 94%
Number of passengers when the flight is overbooked = 300 + 10 = 310
Hence number of passengers who are expected to show up for the flight = 94% of 310 = × 310 = 291.4 = 291 (rounded of whole number as this represents number of passengers)
Step 3 :
Answer :
a) Number of seats expected to be empty = 18
b) Number of passengers expected to show up for flight = 291
Answer:
The ratio of the area of triangle XBY to the area of triangle ABC is
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its areas is equal to the scale factor squared
In this problem
Triangles XBY and ABC are similar, because the corresponding internal angles are congruent
see the attached figure to better understand the problem
step 1
Find the scale factor
Let
z-------> the scale factor
we have
substitute
step 2
Find the ratio of the area of triangle XBY to the area of triangle ABC
Remember that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
we have
-----> scale factor
so
