The students in Mrs. Lees class recorded the temperature at noon every day for a ten day period.The temperatures were 63,64,66,72,76,76,77,82,83,91.What is the range of the temperatures on the 5 coolest days
A.7
B.9
C.13
D.20
C
Right.
thank you
You're welcome.
To find the range of the temperatures on the 5 coolest days, we need to first sort the temperatures in ascending order from the coolest to the warmest.
The given temperatures are: 63, 64, 66, 72, 76, 76, 77, 82, 83, 91.
Sorting them in ascending order: 63, 64, 66, 72, 76, 76, 77, 82, 83, 91.
Now, let's select the 5 coolest temperatures from the sorted list: 63, 64, 66, 72, 76.
The range is calculated by subtracting the smallest value from the largest value. In this case, the smallest temperature is 63 and the largest temperature is 76.
The range = 76 - 63 = 13.
Therefore, the range of the temperatures on the 5 coolest days is 13.
Hence, the correct answer is C. 13.
