Answer:
Step-by-step explanation:
Given the dataset 147, 154, 156, 161, 162,
Mean is the sum of the dataset divided by the total number of dataset.
a) Mean = 
b) The formula for calculating the deviation from the mean for each value is expressed as 
where;
Xi is value of each item
xbar is the mean = 156
Mean deviation of 147 = 147-156 = -9
Mean deviation of 154 = 154-156 = -2
Mean deviation of 156 = 156-156 = 0
Mean deviation of 161 = 161-156 = 5
Mean deviation of 162 = 162-156 = 6
c) Sum of the deviations 
= (-9-2+0+5+6)
= -11+11
= 0
<em>Hence the sum of deviation from the mean is 0</em>

Answer:
10·2^-8 grams
Step-by-step explanation:
The each day, the initial amount for that day is multiplied by 1/2. After 8 days, the initial amount has been multiplied by (1/2)^8, where the exponent of 8 signifies that (1/2) is a factor 8 times in the product.
After n days, the quantity remaining is ...
q(n) = 10·(1/2)^n = 10·2^(-n)
after 8 days the remaining amount is ...
q(8) = 10·2^-8 . . . grams
Answer:
Ans; (657.3÷10)-(94.5÷5) = 65.73 – 18.9 = 46.83

Answer
If I understand the problem correctly, It would be 95 inches squared although the number I got was 95.74, which would actually round to 96. What I think it is asking for is the surface area of the milk carton.
Bottom:
<em>length * width</em>
3 * 3 = 9
Rectangular Sides:
One side would be the length or width (which both equal 3) times the height (6.5), and there are 4 total sides.
<em>number of sides(length or width * height)</em>
4(3 * 6.5) = 4(19.5) = 78
Triangular Sides:
One side would be 
* base (3) times height (1.5), and there are 2 triangular sides.
<em>2(1/2(base * height))</em>
2(1/2(3 * 1.5)) = 3 * 1.5 <em>(The 2 and the 1/2 cancel each other out)</em> = 4.5
The Roof-shaped Top Surfaces:
These are rectangles that you the width is equal to the length of the rectangular prism, and the length is equal to the one side of the triangle. You can find that length by using the Pythagorean theorem (
) which 1.5 is half of the base and the other 1.5 is the height. There are 2 of these rectangles making the final equation 
≈ 4.24.
Now, add up each of the values:
9 + 78 + 4.5 + 4.24 = 95.74.
Comment if you see an error in my work.
How the question has been worded makes me think the answer is (2,5)
