otez555 [7]

Answer:

John is 9.21 km form the school.

Step-by-step explanation:

John leaves school to go home. His bus drives 6 kilometres north and then goes 7 kilometres west. It is required to find John's distance from the school. It is equal to the shortest path covered or its displacement. So,

d=\sqrt{6^2+7^2} \\\\d=9.21\ km

So, John is 9.21 km form the school.

A rectangle is shown with length x plus 10 and width 2 x plus 5. The inside of the rectangle is shaded other than an unshaded sq
klio [65]

Answer:

Step-by-step explanation:

A rectangle is shown with length x plus 10 and width 2 x plus 5.

so the rectangle area = length * width

= (x + 10) * (2x + 5)

an unshaded square with length x plus 1 and width x plus 1

so the unshaded square area = (x + 1) * (x + 1)

the shaded area = rectangle area - square area

= (x + 10) * (2x + 5) - (x + 1) * (x + 1)

= (2x^2 + 20x + 5x + 50) - (x^2 + x + x + 1)

= x^2 + 23x + 49

What do outliers, mean, median, mode, and range tell you PLEASE SHOW EXAMPLES!!!!!!
Zanzabum

Hello there!

Outlier is a value in a data set that varies significantly from the rest of the data.

Example: Way too low: 1, 45, 58, 60, 63, 75

<u><em>Outlier = 1</em></u>

Way too high: 4, 3, 2, 21, 7

The number should be the order from least to greatest are: 2, 3, 4, 7, 21.

<u><em>Outlier = 21</em></u>

It impact the mean and the median in different ways.

Data with no outlier: 4, 5, 7, 11, 12, 15

54÷6=9

<u><em>Mean = 9</em></u>

Data with an outlier: 4, 5, 7, 11, 12, 15, 58

112÷7=16

<em><u>Mean = 16</u></em>

Median is the middle value in an ordered list of numbers.

Example:

Numbers already in order:

1, 5, 8, 10, 13

Numbers not already in order:

13, 1, 5, 10, 8

1, 5,<u> 8, 10,</u> 13, 15

8+10=18 or 18÷2=9

<u><em>Median =9</em></u>

Range is a difference between the maximum (highest) and minimum (lowest) values. It has one type of measure of spread.

Example:

Data in order: <u>23</u>, 27, 39, 53, 62, <u>84</u>

84-23<u>=61</u>

Data not in order: 272, 52, 67, 201, 43, 256

272-43<u>=229</u>

Hope this helps! Thank you for posting your question at here on Brainly.
