Answer:

943.222222222222222222 (the 2 never ends (it repeats))

Do you wanted it to be rounded? If you were to round, you would round it to 943.

Find the perimeter and the area of the polygon with the given vertices. W (11,2), X (11,8), Y (14,8), Z (14,2)

liberstina [14]

Answer:

The perimeter of the polygon = 18 units

The area of the polygon will be $A=18$ square units

Step-by-step explanation:

Computing the Perimeter of the Polygon: 

Considering the polygon with vertices

W (11,2)

X (11,8)

Y (14,8)

Z (14,2)

As the polygon is drawn in coordinate plane as shown in figure a.

From the attached figure a, we can observe that

The length of the side $WZ = 3$ units

The length of the side $ZY = 6$ units

The length of the side $WX = 6$ units

The length of the side $XY = 3$ units

So, the perimeter of the polygon can be calculated by taking the sum of the lengths of all sides i.e.

The perimeter of the polygon = $WZ + ZY + WX + XY$

= 3 + 6 + 6 + 3

= 18 units

Computing the Area of the Polygon: 

Area can be calculated by multiplying the length and width of the polygon.

$A=lw$

So, the area will be:

$A=lw$

$A=(3)(6)$

$A=18$

Therefore, the area of the polygon will be $A=18$ square units

How are dot products useful?

nata0808 [166]

Answer:

An important use of the dot product is to test whether or not two vectors are orthogonal. Two vectors are orthogonal if the angle between them is 90 degrees. ... Thus, two non-zero vectors have dot product zero if and only if they are orthogonal.

What is 18 as a product of its prime factors

Shalnov [3]

Hey there!
We can condense 18 to 9 times nine. However, 9 isn't prime, so we can break that down to 3 times 3 times two, all of which are prime.
Hopefully this helps!

State, with an explanation, whether the mean, median, or mode gives the best description of the following average.

harina [27]

Answer:

C. Mean

A. The distribution is probably symmetric with a single peak.

Step-by-step explanation:

Mean measurement would give best description of the average number of car accidents people had in their lifetime. There are very less chances of skewed distribution because of the nature of the problem.

The data set in this case is not likely to have extreme variations thats why outliers wont be a problem. Therefore, mean measurement would be a better choice than median.

Example:

The typical data for this problem would look something like this.

2, 4, 4, 3, 5, 2, 1, 3

Mean= Sum of all elements/no. of elements

$mean= (2+4+4+3+5+2+1+3)/8=24/8=4$
