Answer:
Step-by-step explanation:
Given that the bivariate distribution of X and Y is described below:
x 1 2
y
1 0.21 0.14 0.35
0 0.47 0.18 0.65
Pdf of Y is
Y 1 0
p 0.68 0.32
C) Pdf of X is
x 1 2
p 0.35 0.65
Mean of X = 
Var(x) = E(x^2)-Mean ^2 = 
C) Mean of Y = 1(0.68)+0 = 0.68
Var(y) = 1(0.68)-0.68^2
= 0.2176
Answer:
Neither.
Step-by-step explanation:
you are correct about the pattern, so it's not adding the same number and not multiplying by the same number. So it's neither.
Answer: 24
Step-by-step explanation:
If you are talking about Least Common Multiple, or LCM, you would start by listing. For example: 6, 12, 18, 24 - 8, 16, 24 You can see that 24 is the LCM.
0.03 you just times it by ten or if its a decimal take away the 0 infront of it
Answer:
D
Step-by-step explanation:
Because it is 1/8 it is much easier.
8 times 5 = 40
So you know that 1/8 was timesed by 40 to get 5. This means you can times x by 40 to get the cups of popcorn the kernels would produce. That means 1 times 40 equals 40. Making the cups of popcorn the kernels would produce is 40.
