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).
Answer:
3. -2
4. 12
5. -4
Step-by-step explanation:
For all problems, let n represent "a number." You will note that when we specify an operation to be done on the equation, it is done to <em>both sides of the equation</em>.
__
3. 5n +(-3) = -13
5n = -10 . . . . . . add 3
n = -2 . . . . . . . . divide by 5
The number is -2.
__
4. (n/2) -7 = -1
n/2 = 6 . . . . . . . add 7
n = 12 . . . . . . . . multiply by 2
The number is 12.
__
5. 2n -1 = -9
2n = -8 . . . . . add 1
n = -4 . . . . . . divide by 2
The number is -4.
Answer:
O sistema de coordenadas cartesianas é usado para visualizar pontos em um gráfico, mostrando as distâncias dos pontos em dois eixos. O sistema de coordenadas cartesianas é um plano bidimensional com um eixo horizontal, conhecido como eixo x, e um eixo vertical, conhecido como eixo y.
Step-by-step explanation:
The product of these two numbers is 62,282.
