Write each expression in Problems 43 - 46 with positive exponents only, and as a single fraction reduced to lowest terms. 2 x − 2 x − 1 − 2 x − 3 x − 1 2
Write each expression in Problems 43 - 46 with positive exponents only, and as a single fraction reduced to lowest terms. 2 x − 2 x − 1 − 2 x − 3 x − 1 2
Solution Summary: The author explains that the lowest form of the given expression using positive exponents is 2(x-1)x3

Examine the Variables: Carefully review and note the names of all variables in the dataset. Examples of these variables include:
Mileage (mpg)
Number of Cylinders (cyl)
Displacement (disp)
Horsepower (hp)
Research: Google to understand these variables.
Statistical Analysis: Select mpg variable, and perform the following statistical tests. Once you are done with these tests using mpg variable, repeat the same with hp
Mean
Median
First Quartile (Q1)
Second Quartile (Q2)
Third Quartile (Q3)
Fourth Quartile (Q4)
10th Percentile
70th Percentile
Skewness
Kurtosis
Document Your Results:
In RStudio: Before running each statistical test, provide a heading in the format shown at the bottom. “# Mean of mileage – Your name’s command”
In Microsoft Word: Once you've completed all tests, take a screenshot of your results in RStudio and paste it into a Microsoft Word document. Make sure that snapshots are very clear. You will need multiple snapshots. Also transfer these results to the…
