The box-and-whisker plot of the data, showing the five-number summary, is shown in the image atatched below.
<h3>What is the Box-and-whisker Plot?</h3>
The box-and-whisker plot is a plot that displays the minimum, maximum, median, lower and upper quartile of a data, which is termed as the five-number summary of a data.
Given the data, 20, 23, 28, 14, 13, 24, 18, 11, find the five-number summary:
- Minimum - 11
- Lower Quartile - 13.5
- Median - 19
- Upper Qaurtile - 23.5
- Maximum - 28
Therefore, the box-and-whisker plot of the data, showing the five-number summary, is shown in the image atatched below.

Answer:
x^2 + y^2 - 4x + 6y - 3 = 0
Step-by-step explanation:
(x-a)^2 + (y-b)^2 = r^2 is the equation of a circle which has center point (a,b) and radius r.
So in this question (2,-3) is the center and r=4.
Then we can write the equation as,
(x-2)^2 + (y+3)^2 = 16
x^2 + y^2 - 4x + 6y - 3 = 0
That is the Equation of the circle.
This is a binomial distribution where 80% of flights arrive on time (p = 0.8) and 20% do not (q = 1 - 0.8 = 0.2). Then the probability that exactly 2 flights arrive late follows the formula:
(nCr)(p^r)(q^(n-r)), where n = 16 (total # of flights), r = 14 (flights that arrive on time)
(16C14)(0.8^14)(0.2^2) = 0.2111
