The oil prices for 2014, rounded to the nearest dollar, were: 95, 101, 101, 102, 102, 106, 104, 97, 93, 84, 76, 59. what is the
kipiarov [429]
- Interquartile Range (IQR) =
, with 
as the upper quartile and 
as the lower quartile.
Firstly, rearrange the data so that it's in ascending order: 
Next, find the median:
Now to find the lower quartile, find the "median" of the data set that's to the left of 99:
Now to find the upper quartile, it's the similar process as finding the lower quartile, except that you are finding the "median" of the data set to the right of 99:
Now that we have the upper and lower quartile, subtract them:
<u>In short, the IQR of this data set is 13.5.</u>
Answer:
b
Step-by-step explanation:
the hypotenuse is equal to the square root of 2 times x in a 45 45 90 right triangle
the square root of 2 times the square root of 2 cancels out to equal 2 and 2 times 3 is 6 so the hypotenuse equals 6
Answer:
The age of the person who entered the room is 15
Step-by-step explanation:
Ages of 5 people in a room are:
17, 16, 15, 17, 22
A person enters room, the mean age of 6 people is 17.
We need to find the age of person who entered the room.
We know that: 
Now, we have mean of 6 people that is 17
We know the age of 5 people while age of one person is unknown.
Let age of person which is unknown= x
So, we can write:
Sum of all data values = 17+16+ 15+ 17+ 22+x
where x is the age of person who enters the room.
Finding x
So, we get the value of x: x=15
Therefore, the age of the person who entered the room is 15.
The hypotenuse of the triangle is 2x
the one opposite of 30 is x
and the one opposite of 60 is sqrt(3)*x
since x=11, the side is 11
