Answer:
The total probability is 13.15%
Step-by-step explanation:
Consider the provided information.
Air-USA has a policy of booking as many as 24 persons on an airplane that can seat only 22.
Studies have revealed that only 86% of the booked passengers actually arrive for the flight.
Therefore, the probability of a person arrive is 0.86
Find the probability that if Air-USA books 24 persons, not enough seats will be available.
That means either 23 person arrive or 24 person arrive.
Probability that 23 persons arrive =
Probability all 24 person arrive =
Total probability is:
Hence the total probability is 13.15%
So, in both cases its not low enough

Your answer would be 0.87 as a decimal and 87/100 as a fraction.
To find these we need to find out how many little squares there are in total, and then how many shaded squares there are.
The shape is 10 squares by 10 squares, which means in total there are 10 × 10 = 100 squares in the whole shape.
To find the number of shaded squares we can count how many aren't shaded and subtract this from 100, and by doing this we get that there are 13 unshaded squares. 100 - 13 = 87 squares.
To convert this into a fraction, we can write it as , which we know is 87/100, which can't be simplified any further.
To convert this into a decimal, we can simply do the division 87 ÷ 100 (which is what the fraction represents), and this gives us 0.87

Answer:
<em>The denominator is 12</em>
Step-by-step explanation:
<u>The Number Line</u>
We can represent any real number in a properly segmented line, where the zero-mark is the separation between positive numbers to its right side and negative numbers to the left side.
We are given the number x = 2/3. Since it's positive, its location lies to the right of the zero but before the 1 as shown in the figure below.
We want to locate a second point y at the same distance from 0 as the point x, so we have two options: y is the same as x, or y is negative at the same distance from zero. We chose the last option.
Its numerator must be 8, so we need to multiply it by 4. But we cannot alter the value of x, so we must also multiply the denominator by 4, which gives us the fraction 8/12, but recall it must be negative.
The denominator is 12
