Answer:
a) Marginal probability of X
b) Marginal probability of Y
c) The probability that the drive-through facility is busy less than one-half of the time is P=0.5.
Step-by-step explanation:
The joint density function of probability is:
a) The marginal density of X is
b) The marginal density of Y is:
c) Probability that the drive-through facility is busy less than one-half of the time. This is P(X<0.5).
I believe it's the first answer choice.
Answer:−3K−395,−374,−198,−187
Step-by-step explanation:
Remove parentheses.
1−3K−396,0−374,0−198,0−187
Simplify 1-3K-3961−3K−396 to -3K-395−3K−395.
−3K−395,0−374,0−198,0−187
Simplify 0-3740−374 to -374−374.
−3K−395,−374,0−198,0−187
Simplify 0-1980−198 to -198−198.
−3K−395,−374,−198,0−187
Simplify 0-1870−187 to -187−187.
−3K−395,−374,−198,−187
Answer:
x = 6
Step-by-step explanation:
6(9+x) = 5(3x)
6*9 + 6*x = 5*3x
54 + 6x = 15x
54 = 15x - 6x
54 = 9x
x = 54/9
x = 6
check:
(9+6)/(3*6) = 5/6
15/18 = 5/6
Answer:
10x, 5, 3x, 1 There are four terms
2) The coefficients are 10 and 3
