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>

Hello!</h2>
The answer is:
The range of the function is:
Range: y>2
or
Range: (2,∞+)
<h2>
Why?</h2>
To calculate the range of the following function (exponential function) we need to perform the following steps:
First: Find the value of "x"
So, finding "x" we have:
Second: Interpret the restriction of the function:
Since we are working with logarithms, we know that the only restriction that we found is that the logarithmic functions exist only from 0 to the possitive infinite without considering the number 1.
So, we can see that if the variable "x" is a real number, "y" must be greater than 2 because if it's equal to 2 the expression inside the logarithm will tend to 0, and since the logarithm of 0 does not exist in the real numbers, the variable "x" would not be equal to a real number.
Hence, the range of the function is:
Range: y>2
or
Range: (2,∞+)
Note: I have attached a picture (the graph of the function) for better understanding.
Have a nice day!
Answer:
Step-by-step explanation:
2^-3=1/2^3
3^-2=1/3^2
(2^-3)(3^-2)=1/72
Let me break this down for you.
Polly walks across the street to buy a cracker (singular)
The sellers of the crackers only have 1 left to sell and there is a long line out the door.
Unless the owners have more frackers readily available to continue to sell, Polly will NOT get a cracker unfortunately.
Hope this helps! :)
