The city of new orleans leaves union station in chicago at 6:00 am and travels south to new orleans. the train travels the 930.0

Naddik [55]

Answer: 460.6 miles South of Chicago

Explanation:

1) The City of New Orleans leaves Union Station in Chicago at 6:00 am and travels south to New Orleans. The train travels the 930.0 miles to New Orleans at an average speed of 79.0 miles per hour.

Scheme:

→to south ←to north
|----------------------|---------------------|
 A x X 930.0 - x B
 6:00 am 6:00 am
 → ←
 v = 79.0 mi/h v = 81.1 mi/h

=> x = 79.0 mi/h * t

2) at the same time the City of Chicago leaves New Orleans and travels north to Nhicago. The train travels the 930.0 miles to Chicago at an average speed of 81.1 miles per hour.

930.0 - x = 81.1 mi/h * t

3) How many miles south of chicago do the two trains pass each other?

Divide the two equations:

930.0 - x 81.1*t
------------- = ----------
 x 79*t

t cancels out =>

930.0 - x 81.1
------------- = --------
 x 79.0

Solve:

81.1x = 79.0(930.0 - x)

81.1x = 79.0 * 930.0 - 79.0x

81.1x + 79.0x = 73,470

=> 160.1x = 73,470

=> x = 73,470 / 160.1

=> x = 460.6 mi

4) Answer 460.6 miles South of Chicago.

I Need Help With Statistics

Ilya [14]

Answer: Choice A) mean, there are no outliers

Have a look at the image attached below. I made two dotplots for the data points. The blue points represent bakery A. The red points represent bakery B. For any bakery, the points are fairly close together. There is no point that is off on its own. So there are no outliers, making the mean a good choice for the center. If there were outliers, then the median is a better choice. The mean is greatly affected by outliers, while the median is not.
