Emily is reading a stapled comic, but 4 of
1 answer:
Pages 5 and 40 are missing and comic had originally 40 pages.
<h3>How to find the missing number of pages and the number of pages of the comic</h3>
Let suppose first that there are no more sheets beyond the sheet containing page 39. A sheet contains two pages, one <em>in front</em> and odd numbered and one <em>behind </em>and even numbered.
If two pages are missing, then another two are missing. According all assumptions, we conclude that pages 5 and 40 are missing and that comic had originally 40 pages.

The vertex is at (-4, -1), and it goes through the point (-3, 1).
Answer:
This interval is between 1.5 and 15.5.
Step-by-step explanation:
Tchebysheff's Theorem
The Tchebysheff's Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by .
In this question, we have that:
Mean = 8.5
Standard deviation = 3.5
The manager wants to publish an interval in which at least 75% of these values lie.
By the Tchebysheff's Theorem, at least 75% of the measures are within 2 standard deviations of the mean.
8.5 - 2*3.5 = 1.5
8.5 + 2*3.5 = 15.5
This interval is between 1.5 and 15.5.
