Answer:

Less than

Step-by-step explanation:

Sample variance is computed by dividing the Sum of Squares (SS) by the number of samples (n).

Population variance is computed by dividing the Sum of Squares (SS) by the difference between the number of samples and 1 (n-1).

After computing, it would be found that the sample variance is less than the population variance.

Answer:

1. $6000

2. 40.9%

3. 51.6%

4. Misc

Explained :

1. 1800 + 150 + 2450 + 1300 + 300 = 6000

2. 2450/6000 = 0.409 = 40.9%

3. 1800 + 1300 = 3100 ; 3100/6000 = 0.516 = 51.6%

4. 300/6000 = 0.005 = 5%

The perimeter of the figure is 58 units

The area of the figure is 130 unit square

Your question is not properly formatted and the diagram required to solve the question is missing.

I've included the appropriate diagram.

To calculate the perimeter of the shape, we simply add up the side lengths of the visible parts of the figure.

Having said that, the perimeter is:

Perimeter = 7 + 8 + 5 + 8 + 3 + 6 + 3 + 5 + 7 + 6

Perimeter = 58

To calculate the area, we use a different approach.

First, we split the figure into 3, we then calculate the area of each sub-figure, and then we add up the calculated areas.

From left to right, we have:

Rectangle 1

Length = 7\\Width = 6

Rectangle 2

Length = 5\\Width = 6+8 = 14

Rectangle 3

Length = 3\\Width = 6

The area of a rectangle is:

Area = Length * Width

So, the area of the figure is:

Area = 7 * 6 + 5 * 14 + 3 * 6

Area = 130

Factor completely.
riadik2000 [5.3K]

25a⁴ - 10a²z² - 8z⁴  <em>multiply 25*-8 = -200 to find factors (10*-20 = 200), (10 - 20 = -10)</em>

25a⁴ + 10a²z²    - 20a²z² - 8z⁴     <em>factor the left two and right two terms</em>

5a²(5a² + 2z²)    -4z²(5a² + 2z²)   <em>one factor from each side should be identical</em>

= (5a² - 4z²)(5a² + 2z²)
