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:
Emily have 33 cookies.
Step-by-step explanation:
Given that:
Batches of cookies baked = 3
Number of cookies in each batch = 13
Total number of cookies = 3 * 13 = 39 cookies
She ate 2 cookies.
Remaining = 39 - 2 = 37 cookies
She gave 10 to her neighbor
Remaining = 37 - 10 = 27 cookies
1 batch = dozen cookies
half batch = 6 cookies
Total cookies = 27 + 6 = 33 cookies
Hence,
Emily have 33 cookies.
(-10)>(-5)>(-0.11)>(1/4), so (-1/2)*(-0.5) is the largest

Answer:
61.4
Step-by-step explanation:
The length of two semicircles of diameter 10 is the circumference of a circle of that diameter:
C = πd = 10π ≈ 31.4
The perimeter includes that length plus the lengths of two straight sides that are 15 units each.
P = 31.4 + 2×15
P = 61.4 . . . . units
Answer:
9.16 minutes per mile
At 10 miles, she is short of her intended rate
Step-by-step explanation:
2 hours means 60 * 2 = 120 minutes
Randy aims to run 13.1 miles in 120 minutes. So to get the rate [min/mi], we must divide total minutes by total miles:
120/13.1 = 9.16 minutes per mile
Moreover, she realized at 10 miles, she has taken 90 minutes. So her rate at that point [min/mi] is:
90/10 = 9 min/mi
Well, Randy is short of her intended rate
