Answer:
B. 4.61 miles
Step-by-step explanation:
midpoint is (-3+4)/2, (2+8)/2 = (1/2, 5)
distance = √(-3-1/2)² + (2 - 5)² = 4.609772299
Using the Poisson distribution to determine the probability that a page contains exactly 2 errors is 0.0163
<h3><u>Solution:</u></h3>
Given that, a book contains 400 pages.
There are 80 typing errors randomly distributed throughout the book,
We have to use the Poisson distribution to determine the probability that a page contains exactly 2 errors.
<em><u>The Poisson distribution formula is given as:</u></em>
Where, 
is event rate of distribution. For observing k events.
And, k = 2 errors.
![\begin{array}{l}{=\frac{1}{\sqrt[5]{2.7}} \times \frac{1}{25} \times \frac{1}{2}} \\\\ {=\frac{1}{50 \sqrt[5]{2.7}}} \\\\ {=0.0163}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%3D%5Cfrac%7B1%7D%7B%5Csqrt%5B5%5D%7B2.7%7D%7D%20%5Ctimes%20%5Cfrac%7B1%7D%7B25%7D%20%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D%7D%20%5C%5C%5C%5C%20%7B%3D%5Cfrac%7B1%7D%7B50%20%5Csqrt%5B5%5D%7B2.7%7D%7D%7D%20%5C%5C%5C%5C%20%7B%3D0.0163%7D%5Cend%7Barray%7D)
Hence, the probability is 0.0163

Answer:
<h3>The purpose of a single linear regression is <u>
To predict a dependent variable from data from multiple independent variables</u></h3>
Step-by-step explanation:
The purpose of a simple linear regression is same as a correlation in that the purpose is to measure a linear relationship between two variables to the end.
In that particular case , its purpose is to "predict" the data from a dependent variable to the data from atleast one independent variable.
