Answer:

<h2>The mean will also increase</h2>

Step-by-step explanation:

Remember that the mean is a central value that shows a representation of all data set. The mean is the value to which all data set is showing a tendency.

So, if we have a symmetric data set, but we add a very high value, that will affect the mean, making it higher, because the mean is sensible to these changes.

Therefore, the mean will also increase, because the sum of all elements is higher.

On a standardized science test, the seniors at Fillmore High School have a mean score of 430 with a standard deviation of 90.
olasank [31]

Answer:

For random samples of 100 seniors, 68% of the sample means fall between 340 and 520

Step-by-step explanation:

As a property of normal distribution, 68% of sample means fall between mean - sigma(430 - 90 = 340) and mean + sigma (430 + 90 = 520) (here, sigma is standard deviation).

Hope this helps!

The ratio of the length to the width of a map is 8 to 5. The map is exactly 32 inches in length. What is the width of the map? A
docker41 [41]
Ratio of length to width of a map = 8:5

Length of the map = 32 inches
Let the width of the map = x inches

So,

Length : Width = 8 : 5
32 : x= 8: 5

x = 5/8 * 32

x = 20 inches

So, the width of the map is 20 inches

lana66690 [7]
If I understood the question correctly, let's set the coordinates (5,5) from the origin (the home). To find the longer side of the triangle, (the distance between the husband and wife), we use A squared * B squared= C squared. 25*25=625, the square root of 625 is 25. So the distance between the husband and wife would be 25 miles. Therefore, one mile less than their distance would be 24 miles. To answer your question, <em><u>Juan is 24 miles from home.</u></em>
