Step-by-step explanation:

30/5 = 6

The operating characteristics of the customer waiting line shows that the average service rate per hour is 5 customers per hour.

The average service rate per hour will be:

= 60/12 = 5

The average number of customers waiting will be:

= (2.2)²/5(5 - 2.2)

= 4.84/14

= 0.3457

The average number of customers in the system will be:

= 0.3457 + 2.2/5

= 0.7857

The average time that a customer spends waiting in the system will be:

= 0.3457/2.2

= 0.1571

Answer:

D. multiply the second equation by 4​

Step-by-step explanation:

3x + 8y = 20 __ equation 1

5x – 2y = 4 ___ equation 2

multiply the second equation by 4​

3x + 8y = 20 __ equation 1

20x – 8y = 16 ___ equation 2

============

23x = 36

x = 36/23

y = (4-5x)/-2

y = (4-5(36/23))/-2

y = 44/23

Step-by-step explanation:

20+15=35%

to find the original price all we have to do is use the formula-

original price = sale price / (1 - percent off/100)

original price = 108.80 / (1 - 35/100)

original price = 167.3846...

original price = 167.38

Answer:

1p 2p 2p 2p 5p 5p 10p

Step-by-step explanation:

Available coins that are less than 11p:  1p 2p 5p 10p

11p with two coins ⇒ 1p + 10p only

11p with three coins ⇒ 1p + 5p + 5p only

11p with three coins ⇒ 2p + 2p + 2p + 5p only

Therefore, the seven coins that Luke has are:

1p 2p 2p 2p 5p 5p 10p

Answer:

To find the mean, you must add up all of the numbers in the data set and then divide them by the amount of numbers there are.

Step-by-step explanation:

For example:

1, 2, 3, 4, 5

To find the mean, we first add up all of these numbers:

1 + 2 + 3 + 4 + 5 = 15

Next, since there are 5 total numbers here, we divide their sum by 5:

15/5 = 3

That is how we get the mean (or average) of the data set.

Answer:

12cm

Step-by-step explanation:

This is a problem which can be solved with the pythagoras therom.

[tex]a^{2} +b^{2} =c^{2}[/tex]

Plus we can split this triangle into two triangles.

The split triangle has dimensions of 13(bc) by 5 cm(dc).[tex]a^{2} +b^{2} =c^{2}[/tex]

[tex]5^{2} +b^{2} =13^{2}[/tex]

Now we solve for b which is the lenght of bd

[tex]25 +b^{2} =169[/tex]

[tex]b^{2} =144[/tex]

[tex]b = \sqrt{144}[/tex]

[tex]b = 12[/tex]

Therefore the lenght of bd is 12cm

Problem 9 (#16)

In order to figure out when the amount of sunlight becomes 12 hours for the first time, we need to have [tex]S(t)=12[/tex] and solve the function for [tex]t[/tex]:

[tex]\displaystyle S(t)=12+2\sin\biggr(\frac{2\pi}{365}t\biggr)\\\\12=12+2\sin\biggr(\frac{2\pi}{365}t\biggr)\\\\0=2\sin\biggr(\frac{2\pi}{365}t\biggr)\\ \\0=\sin\biggr(\frac{2\pi}{365}t\biggr)\\\\\pi=\frac{2\pi}{365}t\\\\365\pi=2\pi t\\\\\frac{365}{2}=t[/tex]

Thus, B is the correct answer

Problem 10 (#17)

So, you could techincally say that the first two options work as each function has their respective identities true for each option.

Thus, I and II is the correct answer

Problem 11 (#18)

[tex]f(\theta)=g(\theta)\\\\4\sin\theta+1=\cos2\theta\\\\4\sin\theta+1=1-2\sin^2x\\\\2\sin^2\theta+4\sin\theta=0\\\\2\sin\theta\bigr(\sin\theta+2)=0[/tex]

[tex]\displaystyle 2\sin\theta=0\\\\\sin\theta=0\\\\\theta=\{0,\pi\}[/tex]

[tex]\sin\theta+2=0\\\\\sin\theta=-2[/tex]

The solution is indeterminate since -2 does not fall in the range of [tex][-1,1][/tex].

Thus, A is the correct answer

Problem 12 (#19)

Recall that the period of a tangent function [tex]y=a\tan(bx-c)+d[/tex] is [tex]\frac{\pi}{|b|}[/tex]. Hence, if [tex]b=2[/tex], then the period of the tangent function is [tex]\frac{\pi}{2}[/tex]. Since I can't see the graphs, you need to identify which graph has a period of [tex]\frac{\pi}{2}[/tex] (meaning the distance between two vertical asymptotes is pi/2), or post this problem again with the graphs.

Set is defined as the arrangement of elements. They can be represented using the venn diagram.

Given the following sets

U = {x: x is an integer and 2≤x≤10} = {3, 4, 5, 6, 7, 8, 9}
A = {x: 2x+1>7} = {x > 3}

B={x: x^2>20} = {x >± 20}
