We can break down the number 6647 into:
6647=6000+600+40+7
The first 6 in the number is in the thousands place (6,000), and the second 6 is in the hundreds place (600).
The first 6 is 10 times greater than the second one.
Answer:
(6,6)

Answer:
My guess is $29
Step-by-step explanation:
So first I take the difference of the 10th and 6th month, which is 116.
I take that and divide it by 4, because that was the change in 4 months(10-6)
116÷4=29
You need to find a scale factor of dilation (probably contraction) to make the replica.
Given that the units of the original painting are centimeters and the units of the sheet of paper are in inches, you have to convert one of the units.
I choose to covert inches to centimeters.
To do that, use the conversion factor 1 = 2.54 cm / inch
=> 8.5 in * [2.54 cm/in] = 21.59 cm
=> 11 in * [2.54 cm/in] = 27.94 cm
Now determine the scale factor to convert 77 cm to 27.94 cm and 53 cm to 21.59 cm. That just require use of division operation:
77 / 27.94 = 2.76
53 / 21.59 = 2.45
Then the higher scale factor is the relevant one, and you have to reduce the original painting by a factor of (1 / 2.76) which will lead to fit in the sheet of paper.

<u>QUESTION 1</u>
The given data set for the expenditure is
The formula for calculating the mean is given by,
We need to add all the expenditure and divide by the total number of days.
This gives us,
to the nearest hundredth.
<u>QUESTION 2</u>
The standard deviation of the data set is given by the formula;
This implies that,
This will give us,
to the nearest hundredth,
.
<u>QUESTION 3</u>
The variance is the square of the standard deviation.
To the nearest hundred gives,
