The time that customers wait to be served at the delicatessen for a grocery store follows the uniform distribution between 0 and 7 minutes. What is the probability that a randomly selected customer will wait more than 4 minutes at the? deli? A. 0.1429

B. 0.4286

C. 0.5714

D. 0.2857

And we can use the cumulative distribution fucntion given by:

And if we use this formula with the complement rule we have:

And the best option would be:

B. 0.4286

Step-by-step explanation:

Let X the random variable that represent the time that customers wait to be served at the delicastessen for a grocery store. And we know that the distribution for X is given by:

And we want to find the follwing probability:

And we can use the cumulative distribution fucntion given by:

And if we use this formula with the complement rule we have:

And the best option would be:

B. 0.4286

angle uzt is congruent to angle tzy. angle vzw is congruent to angle yzx.

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
