Put numbers in order: 4,5,6,6,7,8,9,9,10,10,12,12,14,15
Cut the list into two equal parts: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Find middle numbers: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Lower quartile: 6
Upper quartile: 12
The difference of the values of the first and third quartiles of the data set is 12 - 6 = 6
Answer:
-5
Step-by-step explanation:
-7 - (-2)
-7 + 2
Example: If you owe someone $7, and you give them $2, how much do you still owe? You are owing him $7 so it's a negative and you give him $2 which is a negative as well since you are giving it to him. So, to answer how much do you still owe, you would add $2 to the $7 you owed, so now, you owe him $5, which is a negative since you OWE him.

The distance walked by Stephen is 42.42 feet
<h3><u>Solution:</u></h3>
Given that In the center of town there is a square park with an area of 900 square feet
Stephen walks from one corner of the park to the opposite corner
To find: Distance walked by Stephen
We need to find the distance that the person walk from one corner of the park to the opposite corner.
So, we need to find the Diagonal of the square park
<em><u>The diagonal of square is given as:</u></em>

Let us find the length of side of square
Given area of square = 900 square feet
<em><u>The area of square is given as:</u></em>

Taking square root on both sides,

Thus length of each side of square is 30 feet
<em><u>Therefore, length of diagonal is given as:</u></em>

Hence, the distance that the person walks 42.42 feet
Answer:
Hannah got $200 for her mom
Step-by-step explanation:
With the numbers in this question you don't even have to worry about percentages.
You can think of it in quarters:
75% is 3 quarters of 100%
(25% + 25% + 25% + 25%)
$150 is 3 quarters of $200
($50 + $50 + $50 + $50)
Hope this helps and isn't a confusing way of explaining it! :)
