The table shows data from a survey about the number of times families eat at restaurants during a week. The families are either

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>

High school students from track teams in the state participated in a training program to improve running times. Before the train

Answer:

b. The values X and Y are independent therefore, the mean is 34 seconds and the standard deviation is 50 seconds

Step-by-step explanation:

Subtraction between normal variables:

When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.

Before the training, the mean running time for the students to run a mile was 402 seconds with standard deviation 40 seconds.

This means that $\mu_X = 402, \sigma_X = 40$

After completing the program, the mean running time for the students to run a mile was 368 seconds with standard deviation 30 seconds.

This means that $\mu_Y = 368, \sigma_Y = 30$

Which of the following is true about the distribution of X-Y?

They are independent, so:

$\mu = \mu_X - \mu_Y = 402 - 368 = 34$

$\sigma = \sqrt{\sigma_X^2+\sigma_Y^2} = \sqrt{40^2+30^2} = 50$

This means that the correct answer is given by option b.

Step-by-step explanation:

To find how much of his body weight in food he requires daily, divide:

$\frac{150}{5000}\div\frac{50}{50}=\frac{3}{100}=0.03=3\%$

Andrew has one book that is 237 inches thick and a second book that is 3.56 inches thick. If he stacks the books, about how tall

sattari [20]

You just add the thickness of the 2 books which is 237+3.56=240.56
Then you round the hundredth place which is 5 and next to it is the number 6 and that’s 5+ so it’s going up by a number. The answer is 240.6 inches tall. I tried explaining it well so sorry if you didn’t understand.
