Answer:Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. ... We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Answer:
The random variables in this case are discrete since they have a Multinomial distribution.
The probability mass function for a discrete random variable X is given by:
Where are 
are possible values of X.
The joint probability mass function of two discrete random variables X and Y is defined as
P(x,y) =P(X=x,Y=y).
It follows that, The joint probability mass function of 
is :
Answer:
you are probably supposed to find what "x" is.
Step-by-step explanation:
Put The X,Y Into Direct Variation " y=kx" You'll Get -17=k(-10)
k = -17 / -10
Now Put The Value Of "k" Into The Formula And You Will Get A (y=17/10x)
