Answer:
a) 0.9961
b) 0.9886
Step-by-step explanation:
We are given the following information:
We treat passenger not showing up as a success.
P(passenger not showing up) = 0.10
Then the number of passengers follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 125
a) probability that every passenger who shows up can take the flight
b) probability that the flight departs with empty seats
Answer:
side length of one square
Step-by-step explanation:
the side lengths of the quilt is:
length = 4.5 ft
breadth = 3 ft
We also know that the areas of all 24 squares add up to fill this area of 13.5 as well
Hence,
to find the area of one square just divide 13.5 by 24
to find the side length of one square recall the area formula for a square.
length of side length of one square.
NOTE:
You can do this easily by dividing the side length of either side of the quilt by the number of squares on that side of the quilt.
Answer:
107 degrees
Step-by-step explanation:
First, subract 180 from 135 to get the angle for DFE, which is 45 degrees.
Then, add 45 to 28, which equals to 73 degrees.
Finally, subtract 180 from 73 to get the angle for DEF, which is 107 degrees.
Answer:
1) congruent
2) corresponding angles
3) 3x+21 = 6x-60
4) x =9
Step-by-step explanation:
1) congruent becuase supplementary means that these 2 angles add up to make 180 degrees.
2) the file below
3) we know they are equal because the congruent correspoding angles.
4) 3x+21 = 6x-60
=> 21 = 9x-60
=> 81 = 9x
=> 9 = x
