Answer:
1:8
Step-by-step explanation:
soln,
In ,1hour= 60 mins
2hour= 2*60 mins = 120 mins.
now,
15/120( then divide 15 ones 15 and 15 * 8 is 120.) explanation
= 1/8
OK so each block is 3cm tall and 3.5cm wide (because 2 are 7cm wide)
so to measure the perimeter count all the side values for example:
the 5 squares at the bottom which measure 3.5cm each adds up to a total of 17.5cm then if you add the top 2 flat sides that's another 2, 3.5cm which adds up to 7cm. 17.5cm + 7cm = 24.5cm then their are 3 walls on each side measuring 3cm each so 3cm * 6 = 18
24.5cm + 18cm = 42.5cm (I think this is correct)
The length equals 42 inches because you take 36+36 because there are two widths and that equals 72. Then take 156-72 which equals 84. Take 84 divided by two because there are two lengths and you get 42 inches!
Answer:
0.0159
Step-by-step explanation:
Given that a common practice of airline companies is to sell more tickets for a particular flight than there are seats on the plane, because customers who buy tickets do not always show up for the flight.
Here if X is the no of persons that do not show up, then X is binomial as each trial is independent with p = 0.04 and n =150 (no of tickets sold)
The plane is overbooked if more than 150 show up
i.e. less than 2 do not show up
Hence the probability that the airline overbooked this flight
=
