The mean is the average you're used to, where you add up all the numbers and then divide by the number of numbers. The median is the middle value in the list of numbers. Mode is the number which appears most often in a set of numbers.

Hope this helps you :)

Calculate the perimeter and area for the parallelogram if a = 2.8 ,b = 16.5 and h = 11.5
Nana76 [90]

Perimeter = 2(a+b)

= 2(2.8+16.5)

=2(19.3)

Perimeter = 38.6

Area=base x height

=2.8 x 11.5

=32.2

A family of right triangles has side lengths in the approximate ratio 3:4:5. One right angle
velikii [3]

Answer:

2,016.67 sq. cm

Step-by-step explanation:

Given the approximate ratio of the sides of a rectangle as 3:4:5.

Total ratio = 3+4+5 = 12

Area of the rectangle = 1/2*base *height

get the base;

base = 3/12 * 220

Base =  55cm

Get the height

Height = 4/12 * 220

Height = 880/12

Height = 73.3cm

Area = 1/2 * 55 * 73.3

Area = 2,016.67 sq. cm

What do projections do to things like shapes,direction,distance,and areas on map?
Komok [63]
A distortion is the alteration of the original shape (or other characteristic) of an object, image, sound, waveform or other form of information or representation. Distortion is usually unwanted. In some fields, distortion is desirable, such as electric guitar (where distortion is often induced purposely with the amplifier or other electronic effect to achieve a unique sound). The slight distortion of analog tapes and vacuum tubes is considered pleasing in certain situations. The addition of noise or other extraneous signals (hum, interference) is not considered to be distortion,[citation needed] though the effects of distortion are sometimes considered noise.
In Geographical Information Systems, portraying the world on a flat map is necessary to appropriately observe the world in a smaller, yet more convenient way. Unfortunately, anytime that a round object is broken up and flattened, it creates many areas of distortion. Some areas stretch, while others are cut. When the earth is projected onto a flat surface there are at least four different types of distortion: distance, direction, angle, and area. It is impossible to preserve all four means of distortion on one flat projection.

So I think the answer is A?

I don’t know but I think goodluck?
