This is the one and i know its probably super easy but i dont know

DENIUS [597]

Step-by-step explanation:

this one is a "thousand times" more complex than the inequality question to put there.

still easy, yes, for an experienced person, but here it is clear you need to understand lines, coordination grids, and overall deal with 2 variables (here : x and y) and therefore 2 dimensions.

the general line function is typically presented as

y = ax + b

a is the slope. that is the ratio of "y coordinate change / x coordinate change" when going from one point on the line to another.

and b is the y-intercept (the y value when x = 0), giving us the information about the point, where the line crosses the y-axis.

and so, look for yourself, which of the 4 equations has a b of +3 ?

y = 3x no, b = 0

y = x + 3 yes, b = 3, this is correct

y + 3 = x hmm. let's first bring it into the normed form

y = x - 3 aha ! no, b = -3

y = x - 3 no, the same thing as before. b = -3

A single-server waiting line system has an arrival pattern characterized by a Poisson distribution with 3 customers per hour. Th

sweet-ann [11.9K]

Answer:

18 minutes

Step-by-step explanation:

Given that:

The arrival time = 3 customers / hour

The avg. service rate (s) = 12 minutes per customer

To hour, we have:

$s = \dfrac{60}{12}$

s = 5 customers/ hour

Thus, the required average time for a customer needs to wait in line is:

$= \dfrac{3}{5}\times (5-3) hours \\ \\ = \dfrac{3}{5}\times 2 \\ \\ = \dfrac{3}{10} \ hours$

To minutes;

$= 3 \times \dfrac{60}{10} \ minutes$

= 18 minutes

Does anyone know the answer

lisov135 [29]

It is also 125 degrees, or B.
Angle o and angle z are basically the same angle, just on different sides of the line. These are called vertical angles.
