The slope-intercept form of the equation
is ![y = \frac{-1}{2}x + 2](/tpl/images/0045/0404/0511e.png)
The given equation is:
x + 2y = 4
The slope-intercept form of the equation of a line is:
y = mx + c
where m represents the slope
c represents the y-intercept
Express the equation x + 2y = 4 in the form y = mx + c
x + 2y = 4
2y = -x + 4
Divide through by 2
Therefore, the slope-intercept form of the equation
is ![y = \frac{-1}{2}x + 2](/tpl/images/0045/0404/0511e.png)

Ответ:
x + 2y = 4
Slope intercept form is y = mx + b where m = slope and b = y-intercept.
In this case
x + 2y = 4
2y = -x + 4
y = -1/2 x + 2
Answer
Slope intercept form: y = -1/2 x + 2
Ответ:
a)
P(Y=1|X=2) = p(2,1) = 0.1
P(Y=2|X=2) = p(2,2) = 0
P(Y=3|X=2) = p(3,2) = 0.1
b)
NO
c)
P(X+Y>3) = 0.55
P(XY=4) = 0
P(XY>2) = 0.55
Step-by-step explanation:
The joint probability table is given in the picture attached
(See picture)a)
P(Y=1|X=2) = p(2,1) = 0.1
P(Y=2|X=2) = p(2,2) = 0
P(Y=3|X=2) = p(3,2) = 0.1
b)
Two events A and B are independent if, and only if,
P(A|B) = P(A) and P(B|A) = P(B)
X and Y are not independent since
P(Y=1|X=2) = p(2,1) = 0.1
whereas
P(Y=1) = 0.5
so we can see
P(Y=1|X=2)≠ P(Y=1)
c)
P(X+Y>3) = p(1,3)+p(2,2)+p(2,3)+p(3,1)+p(3,2)+p(3,3)=
0.05+0+0.1+0.1+0.05+0.25 = 0.55
P(XY=4) = p(2,2) = 0
P(XY>2) = p(1,3)+p(2,2)+p(2,3)+p(3,1)+p(3,2)+p(3,3) = 0.55
