I solved for the length of one side, which came out to (3/2)x -5.

Let's try something new:

Perimeter = 6x - 20 = 2W + 2L, but here W = L because this is a square.

Then 6x - 20 = 4W = 4x

Then 6x - 4x = 20;   2x = 20;   x = 10.

This is a square with side length 10.  Its perimenter is thus 4(10) = 40.

Does 6(10) - 20 = 40?  Yes.  So, x = 10.

Cami goes scuba diving. She descends 18 feet in 3 minutes. Which expressions represent the average rate at which Cami’s position
julsineya [31]

Answer:

6 ft/min

Step-by-step explanation:

Theres a neat trick to note; whenever you say per think of it as a fancy word for divide, because the label is always gonna be a/b (a per b)

Therefore,

the rate of feet per minute will be the feet divided by the minutes;

18 feet in 3 minutes = <u>18</u>/3 <u>ft</u>/min

Therefore the rate is 6 feet per minute.

<u>IF you need an explanation on what average rate implies:</u>

<em>Note; the word average is not prudent to answer as its extraneous, however if there was more data like "Cami descends 18 ft in 3 min and Nami descends 9 ft in 3 minutes; whats the average rate at which they descend" then you'd have to add the two rates up and divide by two.</em>

Hope this helps :)

Single Factor ANOVA is a method we use when we want to compare a quantitative variable among more than two categories.
Goryan [66]

Answer:

The given statement is "True".

Step-by-step explanation:

A statistical analytical technique that divides the perceived aggregate unpredictability present throughout an information source even further into 2 components.

  • Systemic components
  • Random components

If relevant information yet another category independent variable, as well as another quantifiable variable of interest, has been obtained, are using a single-way ANOVA.

Thus the above is the true answer.
