Answer:

Step-by-step explanation:

THe mean deviation is the sum of all the differences of the values from the mean and then we divide by the number of values in the data set.

First, lets find the mean (sum of all the numbers divided by number of numbers):

Mean = (271+354+296+301+333+326+285+298+327+316+287+314)/12 = 309

Now, the mean deviation:

|(271-309+(354-309+(296-309+.....(314-309))|/12 = 19.33

The mean absolute deviation (MAD) is equal to 19.33

Correct answer is C

at an airport it costs 7 dollars to park for up to one hour and five dollars per hour for each additional hour. let x represent

ivann1987 [24]

I came up with 7+5(x-1)
7 is a fixed one time cost.
5(x-1). x-1 because you have already charged $7 for the first hour.

Checking to make sure it is correct
so if a person stays 1 hour
7+5(1-1)
7+5(0) = 7
This answer makes sense because they get charged $7 the first hour

so say they stay 3 hours
7+5(3-1)
7+5(2) = 17
This answer makes sense because they get charges $7 for the first hour and $5 for the other 2. so 7+5+5=17.

we can see that the function works

0.000027 divided by 0.000009 I got 3 but It doesn't seem right to me for some reason.

Elan Coil [88]

3 is the correct answer, you could always check your work by dividing 0.000027 by 3 which would get you 0.000009. I hope this helped =)

Eliot is simplifying a radical. His work is shown.

Answer:

Answer is C.

The work shown above is correct; however, 2√16 maybe simplified further.

because √16 = 4

so 2√16 = 2 * 4 = 8
