To find the mean, you add all the numbers together and then divide by the number of numbers (6).
4 + 12 + 20 + 24 + 32 + 40 = 132
132/6 = 22
To find the mean absolute deviation, you will find the distance between each number and the mean and then divide this by 6 as well.
(22-4) +(22-12)+(22-20)+(24-22)+(32-22)+(40-22)
18 + 10 + 2 + 2 + 10 + 18 = 60
60/6 = 10
The mean absolute deviation is 10.
The correct answer is that Stefano should have divided by 6 when finding the mean absolute deviation.
Answer:
40 minutes (I think)
Step-by-step explanation:
Calculate the time into minutes
15mph-0.25mpm
18mph-0.3mpm
add them together to find out how far they go combined each minute
0.55
divide 22 by 0.55 to find the total time
40 minutes
Hello,
Shall we begin?
136 + x = 255
x = 255 - 136
x = 119
