Answer:
x=39
Step-by-step explanation:
Answer: E. 40
Step-by-step explanation:
The x-intercept of a line is when the y coordinate is equal to zero, so input zero in for y and solve for x to find the x-intercept.
1/2x + 3/5(0) = 20
1/2x = 20
x = 40
Answer:
the 3rd
Step-by-step explanation:
because n^2+3n+2n simplifies to n(n+5), which is not equivalent to 6n
It is a negative slope and the answer is -3
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 :
