The second one, x=(0.18)(23.5)
9/50=x/300
you would have to cross multiply. 2,700=50x
then you want x by itself so you divide each side by 50.
x=54
Answer:
we can't see the question it would help if we did
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The answer is graph D because in the word problem it says, "more than three copies". We can also see that we need to find how many copies are made in 4 hours. Since it says more than and we do not have another number, we will multiply 3 and 4.
3 x 4 = 12
This is a line graph. An enclosed circle on a number would mean that this line includes the number. This circle is open, not enclosed so 12 is not a part of the line for graph D.
Since it says more than, this open circle makes sense, because it was more than 3 books, but not 4 books. This means it can range anywhere after 3. (examples: 3.1 books, 3.5 books, 3.8 books) this means it can also range anywhere after twelve.
This combined shows us that graph D is the answer.
The mean absolute deviation is the mean of the absolute values of the differences of the numbers from their mean. It is convenient to let a spreadsheet or calculator do the tedious math. Here it is by hand:
Total of given values: 135
Mean of given values: 135/6 = 22.5
Deviations of given values from the mean:
... {2.5, 1.5, 2.5, 0.5, -2.5, -4.5}
Absolute values of deviations from the mean:
... {2.5, 1.5, 2.5, 0.5, 2.5, 4.5}
Total of those: 14
Mean absolute deviation: 14/6 = 2 1/3.
