Answer:
x is less than 1/9
Step-by-step explanation:
Distribute the 3/2 to the (6-18x), which gives you 9-27x is greater than 12. Subtract the 9 over, which gives you -27x is greater than 3. Divide both sides by -27, but when you divide by a negative, you have to flip the sign, so finally, you get x is less than 1/9.
The gradient of x axis is zero. As such, the gradient of the line parallel to x-axis can only be zero
Answer:
48+2x=180
Step-by-step explanation:
This is an isosceles triangle, this means that two of the sides/angles are the same. I'm not 100% sure if I'm right though.
Answer:
The joint probability distribution of X and Y is shown below.
Step-by-step explanation:
The distributions of X and of Y are described as follows:
X : 0 1
P (X) : 0.23 0.77
Y : 1 2 3
P (Y) : 0.40 0.22 0.38
It is provided that X and Y are independent.
That is:
P (X ∩ Y) = P (X) × P (Y)
Compute the joint probability distribution of X and Y as follows:

X 0 1
<u>Y </u>
1 0.9200 0.3080
2 0.0506 0.1694
3 0.0874 0.2926
I honestly dont know how to figure this one out.
