False. An equilateral polygon with 108 degrees would be an equilateral triangle.
Answer:
A) 20.82 > 20.55
Step-by-step explanation:
Hopefully, your issue is with the symbols (< vs >) rather than actually determining which number is larger or smaller.
The wide-open end of the symbol (the left side, in the case of >) indicates the larger (more positive) number.
So, the meanings of the symbols are ...
> — "is greater than"
< — "is less than"
The only true statement of those listed is ...
20.82 is greater than 20.55, or 20.82 > 20.55 . . . . selection A
_____
When writing number comparisons, I like to use the < symbol, because it puts the numbers in number-line order. That is, the smaller (or more negative) number is on the left, just as it is on a number line.
You trade the places of the numbers when changing the symbol. For example, answer choice A could be rewritten as ...
20.55 < 20.82
You know that 20.55 is to the left of 20.82 on the number line, so you know this statement is true.
Answer:
x=5, y=-9. (5, -9).
Step-by-step explanation:
y=-3x+6
y=-x-4
--------------
-3x+6=-x-4
-3x-(-x)=-4-6
-3x+x=-10
-2x=-10
2x=10
x=10/2
x=5
y=-5-4=-9
Answer:
A form of blocking by three variables.
Step-by-step explanation:
Graeco-Latin square design is a special type of comparative design.
Graeco-Latin square design uses 3 blocking variables unlike the 2 blocking variable as used by the standard Latin square design.
In this square design of experiment, the experimental units are grouped into three different ways.
