1/4 + 3/10 = 10/40 + 12/40 = 22/40
40/40 = 22/40 = 18/40
18/40 = cranberry j
Ratio=
A : O : C
10/40 : 12/40 : 18/40
0.25 : 0.3 : 0.45
You can just plug in one of the points to each equation until you get an equality that is true.
I chose to use (-3,2)
1. 5x+3y=1
5(-3)+3(2)=1
(-15)+ 6 = 1
(-9) = 1 <<<(FALSE)
2. x+5y=3
(-3)+5(2)= 3
(-3)+10= 3
7=3 <<<(FALSE)
3. 3x+5y=1
3(-3) + 5(2)= 1
(-9)+10=1
1=1<<<(TRUE)
So, the correct equation is 3x+5y=1.
Make sense?
In statistics, the number of degrees of freedom is the number of values in the final calculation of a statistic that are free to vary.
The number of independent ways by which a dynamic system can move, without violating any constraint imposed on it, is called number of degrees of freedom.
In other words, the number of degrees of freedom can be defined as the
minimum number of independent coordinates that can specify the position
of the system completely.
<span>
The degree of freedom represents the number of ways in which the expected classes are free to vary in the chi-square goodness-of-fit test.</span>
You would just take .5x5 which would be 2.5 inches without the snow melting it would add up to 13.5in the last part with the tt I’m not sure but it follows the same principle .5x(Time)+the original amount will give you the answer
