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>

The Price of Car A rounded to the Nearest £100 is £12400

The Price of Car B rounded to the Nearest £100 is £16800

The Price of Car C rounded to the Nearest £100 is £14600

Difference between the Rounded Price and Original Price of Car A :

⇒ (£12400 - £12380) = £20

Difference between the Rounded Price and Original Price of Car B :

⇒ (£16800 - £16760) = £40

Difference between the Rounded Price and Original Price of Car C :

⇒ (£14600 - £14580) = £20

From the above, We can Notice that :

The Price of Car B changes by the greatest amount.

2/3=x/6=9/y to find the value of y in this proportion you must divide 54 by
scZoUnD [109]

Answer:

You must divide 54 by 4

Step-by-step explanation:

we have

\frac{2}{3}=\frac{x}{6}=\frac{9}{y}

Step 1

Solve for x

\frac{2}{3}=\frac{x}{6}

3x=6*2\\x=12/3\\x=4

Step 2

Find the value of y

\frac{x}{6}=\frac{9}{y}

Substitute the value of x

\frac{4}{6}=\frac{9}{y}

4y=9*6\\y=54/4\\y= 13.5

therefore

You must divide 54 by 4

lidiya [134]

Answer:

696 miles at the first day, and 174 miles at the second day.

Step-by-step explanation:

Given:

Richard and Linda enjoy visiting Hilton Head Island, South Carolina.

The distance from their home to Hilton Head is 870 miles.

So, the drive takes them 2 days.

<u>Richard and Linda travel four times as far the first day as they do the second day.</u>

Question asked:

How many miles do they travel each day?

Solution:

Let Richard and Linda traveled at the first day = x\ miles

Then Richard and Linda traveled at the second day will be = 4x\ miles

Total distance from their home to Hilton Head = 870 miles

Traveled at the first day in miles + Traveled at the second day = 870

4x+x=870\\ \\ 5x=870\\ \\ Dividing\ both\ sides\ by\ 5\\ \\ x=174\ miles

By substituting the value:

Richard and Linda traveled at the first day = x\ miles = 174 miles

Richard and Linda traveled at the second day will be =  4x\ miles

=4\times174=696\ miles

Therefore, they traveled 696 miles at the first day and 174 miles at the second day.

For the Black Panther Trip 420 students were scheduled to go. After collecting more parent surveys, 15% more students are going
natulia [17]

Answer: $ 10,988.25

Step-by-step explanation:

Hi, to answer this question, first we have to multiply the original number of students scheduled to go to the trip (420) by the added students’ percentage (15%) in decimal form (divided by 100)

420 x (15/100) = 420 x 0.15 = 63 students added

Adding the number of extra students to the original number:

420+63 = 483 students (total number of students)

Finally, we have to multiply the result by the cost of each admission ticket (22.75)

483 x 22.75 = $ 10,988.25
