Find the median for the given sample data. the distances (in miles) driven in the past week by each of a company's sales represe
dolphi86 [110]

Hi there!

To find the median, list all the numbers in a least to greatest order then find the number in the middle. If there is an even number of numbers, find the mean (average) between the two numbers in the middle.


You are given 107, 114, 214, 230, 436, and 445. They are already in order from least to greatest. There is an even number of numbers (6), so find the two numbers in the middle.


214 and 230

Now find the mean between these numbers. To find the mean, add up both the numbers then divide by how many numbers you added up (2).


214 + 230 = 444

444 ÷ 2 = 222


The mean of the two numbers in the middle is 222. The median distance driven in the data is 222 miles.

Hope this helps!

juin [17]

Answer:

1 and 0

Step-by-step explanation:

sin( \frac{\pi }{2} ) = 1, hence

sin³(\frac{\pi }{2} ) = 1³ = 1

cos( \frac{\pi }{2} ) = 0, hence

cos³ (\frac{\pi }{2} ) = 0³ = 0
