Answer:
Mean absolute deviation = 1.6.
Step-by-step explanation:
The mean = (4+4+ 6+ 6+ 7+ 8+ 8 + 8 +9+ 10) / 10
= 7.
List the differences from the mean:
4 - 7 = -3
-3
-1
-1
0
1
1
1
2
3
Sum of the absolute value of the difference
= 3 + 3 + 1 + 1 + 0 + 1 + 1 + 1 + 2 + 3
= 16.
So the Mean Absolute deviation = 16 / 10 = 1.6.
Answer:
279 ft^2
Step-by-step explanation:
The area of a rectangle of length L and width W is A = LW.
Here, that area is (19.25 ft)(14.5 ft) = 279.125 ft^2, or approx. 279 ft^2
I am going to go on a limb here and say that C, or the third one is incorrect. I would love to say it is A, or the first one, but i'm not completely sure, if it's wrong I am really sorry!
Answer:
2500 is not a reasonable estimate.
Step-by-step explanation:
We are given the following in the question:
Number of pages read by Josie = 246
Pages read by older brother = 3 to 4 times as many pages as Josie
If x represents the number of pages read by her brother, we can write:
Putting values, we get,
Since, 2500 does not lie in this interval
Thus, 2500 is not a reasonable estimate for the number of pages that Josie's brother read.
