Answer:

1. c

2. f

3. d

Step-by-step explanation:

This type of queuing model is an example of "single-channel, single-phase" process.

However, from the information given:

The inter-arrival rate = 10 customers per hour

Arrival time = 6 minutes

Service time = 5 minutes

∴

utilization = service time/arrival time

= 5/6

Time on queue [tex]T_q = p \times \dfrac{utilization }{1 - utilization} \times \dfrac{Cv_a^2 -Cv_b^2}{2}[/tex]

[tex]T_q = 5 \times \dfrac{5/6 }{1 -5/6} \times \dfrac{(2.58^2 -0.75^2)}{2}[/tex]

[tex]T_q = 25 \times 3.60945[/tex]

[tex]T_q = 90.24 \\ \\ T_q \simeq 90 \ mins[/tex]

Thus, customer waiting in the queue line is;

[tex]= \dfrac{T_q}{q} \\ \\ = \dfrac{90}{6} \\ \\ \mathbf{=15}[/tex]

Thus, new customers will have to wait in a total time of;

= waiting time + service time

= 90 + 5

= 95 minutes.

Answer:

The seat no of a plane is 2

Answer:

The slope is -2

Step-by-step explanation:

Rewrite in slope-intercept form.

The slope-intercept form is y = mx + b, where m

 is the slope and b is the y-intercept.

[tex]y = mx + b[/tex]

Reorder 4 and -2x.

[tex]y = - 2x + 4[/tex]

Using the slope-intercept form, the slope is −2.

[tex]m = - 2[/tex]

Hence, the slope is -2.

The equation y = 4- 2x has a slope of -2.

The pitch of a direct equation is the measure of the term containing the independent variable( in this case," x").

In the equation y = 4- 2x, the measure of "x" is-2. thus, the pitch of the equation is-2.

We know equation is in slope-intercept form (y = mx + b), where "m" represents the slope.

The slope represents the rate of change of the dependent variable (y) with respect to the independent variable (x).

In this case, for every unit increase in x, the value of y diminishments by 2 units. This indicates a downcast pitch.

In summary, the equation y = 4- 2x has a slope of -2.

Answer:

120 m

Step-by-step explanation:

.

Answer:

length = 20m

width = 10m

Step-by-step explanation:

perimeter = 2 (length + width)

length = 2 * width = 2w

perimeter = 2 (2w +w)

perimeter = 2(3w)

60m = 6w

(divide both sides by 6)

60/6 = w

width = 10m

length = 2w

so length = 2 * 10 = 20m

Answer:

5) arccos A = 28°

6) arcsin A = 53°

Step-by-step explanation:

5) cos A = 30/34

6) sin A = 32/40

5)

For a right triangle, the cosine of an angle is the ratio between the length of the adjacent side and the length of the hypotenuse (the hypotenuse is the longest side of the triangle).

In this case,

cos(A) = adjacent / hypotenuse = 30 / 34 = 15/17

6)

For a right triangle, the cosine of an angle is the ratio between the length of the opposite side and the length of the hypotenuse.

In this case,

sin(A) = opposite / hypotenuse = 32 / 40 = 4/5

A way to remember sine, cosine, and tangent is SOHCAHTOA, where

SOH is Sine = Opposite / Hypotenuse

CAH is Cosine = Adjacent / Hypotenuse

TOA is Tangent = Opposite / Adjacent

Answer:

$ 28,665.11 must be deposited today into the account.

Step-by-step explanation:

Given that there is an account with monthly compounding and an APR of 4%, to determine how much must be deposited today into the following account in order to have $ 35,000 in 5 years, the following calculation must be performed:

X x (1 + 4/12) ^ 5x12 = 35,000

X x (1 + 0.333) ^ 60 = 35,000

X x (1,333) ^ 60 = 35,000

X x 1.220999 = 35,000

X = 35,000 / 1.22099

X = 28,665.11

Thus, $ 28,665.11 must be deposited today into the account.

Answer:

The answer would be y=-2x

Answer:

Equation y =2x represent the direct variation .

Step-by-step explanation:

Given : Equations  y = 2x  , y = x + 4  , y = 1/2x  , y = 3/x .

To find  : Which equation represents a direct variation.

Solution : We have given that equations

Direct variation : The statement "y varies directly as x," mean  y and x always have the same ratio: k = .

Where k is constant of variation ,

We can write it as  y = kx  .

We can see that  in equation y = 2x  is the same as the above equation

On comparing k = 2.

Therefore, Equation y =2x represent the direct variation .
