Answer: Mean= (-) 9.5
Explanation:
We have given that ,
The set of numbers are -11, -22, -2, -3
Since we have the numbers which are negative only so the mean will be negative as well.
∴ Mean = 
So it becomes ,
Mean = 
= 
= (-)9.5
∴ Mean of given set of numbers = (-) 9.5
The domain is the x value.
List the x value of where all the dots are:
-6, -4, -2, 1, 4
To properly make the comparison between the weights of the books, we compute for their weights in similar units. For this item, we need to convert the weight of the first book to kilogram.
conversion:
Book 1 : (7.49 lbs) x (0.4535924 kg / 1 lb) = 3.397 kg
Since the second book weights 3.91 kg, it is heavier than the encyclopedia. Subtracting the weight of the first book from the second one will give us an answer of 0.51 kg. Thus, the answer to this item is letter D.
Six hundred thirty two and seven hundred forty five thousandths.
600 + 30 + 2 + .7 + .04 + .005
