To solve this problem, let us first define what is mean
and median. Mean is the average of all the numbers in the data set while
the median is the number in the middle of the data set in ascending order.
If we create a box plot for the data of Rome and New York,
we can see that there is an outlier in the data for New York. Since New York
has an outlier, so the mean is not a good representation on the central
tendency of the data. The mean is skewed (distorted) by the outlier. So in this
case it is better to use the median.<span>
While the Rome data is nice and symmetrical, it does not seem
to have an outlier, so we can use the mean for this data set.</span>
Therefore the answer is:
<span>The Rome data center is best described by the mean. The
New York data center is best described by the median</span>
128 oz. in one gallon. 35 cups of 12 oz. equals 420 oz. 420 divided by 128 equals 3.28 so youll need 4 bottles. D.
Answer:
Domain: All numbers greater than or equal to 0. By definition, the domain of a graph, is the possible x values.
Range: All real numbers. By definition, the range is all possible x values.
Not a function. A function has y value for every x value.
<span>n aircraft travels with the wind for 120 miles in 0.75 of an hour. The return trip is flown against the wind and takes exactly 1 hour.
Which system of linear equations represents x, the speed of the plane in miles per hour, and y, the speed of the wind in miles per hour?
---
With wind DATA:
distance = 120 miles ; time = (3/4)hr ; rate = 120/(3/4) = 160 mph
----
Against wind DATA:
distance = 120 miles ; time = 1 hr ; rate = 120 mph
-----
Equation::
Let p be speed of the plane in still air
Let w be speed of the wind
==================================
With wind:: p + w = 160 mph
Against wind:: p - w = 120 mph
================================
