First, you need to find the mean of all this set of numbers. You would add them all together and then divide by 6 which is 50.5.

Now you find the sample variance. Subtract each number from the mean. 

<span>15.5, 13.5, 8.5, -6.5, -10.5, -19.5 </span>

After, you square each value and add them. 

<span>240.25+182.25+72.25+42.25+110.25+380.2... </span>
<span>= 1027.5 </span>

Now divide by 5 (because it's a sample variance) and you get 205.5.

[|(x-4)÷(x+5)|]\leq[4]
Katena32 [7]

Answer:

Solutions are;

x = -8

x = -3.2

Step-by-step explanation:

Here, we want to solve the given equation for x

|(x-4)/(x + 5)| = 4

From what we have, this is an absolute value equation and thus, we are going to have two solutions

These are;

x-4/x+ 5 = 4

x-4 = 4(x + 5)

x-4 = 4x + 20

x-4x = 20 + 4

-3x = 24

x = -24/3

x = -8

secondly;

x-4/x+5 = -4

x-4 = -4(x + 5)

x-4 = -4x - 20

x + 4x = -20 + 4

5x = -16

x = -16/5

x = -3.2

Find the volume of the square pyramid showing. round to the nearest 10th if necessary
solong [7]
The volume of a square pyramid is (1/3)(area of base)(height of pyramid).

Here the area of the base is (10 ft)^2 = 100 ft^2.

13 ft is the height of one of the triangular sides, but not the height of the pyramid.  To find the latter, draw another triangle whose upper vertex is connected to the middle of one of the four equal sides of the base by a diagonal of length 13 ft.  That "middle" is 5 units straight down from the upper vertex.  Thus, you have a triangle with known hypotenuse (13 ft) and known opposite side 5 feet (half of 10 ft).  What is the height of the pyramid?  
To find this, use the Pyth. Thm.:  (5 ft)^2 + y^2 = (13 ft)^2.  y = 12 ft.

Then the vol. of the pyramid is (1/3)(area of base)(height of pyramid) =
(1/3)(100 ft^2)(12 ft) = 400 ft^3 (answer)

What is 73.24 rounded to the nearest tenth
Jobisdone [24]

The best way to remember which place is rounded to the nearest 10th, 100th, 1000th, etc., is by counting the number of 0's.

This question wants you to round to the nearest 10th.

How many 0's does 10 have? 1.

So we round one space after the decimal.

This gets us 73.2
