The subset of A is B = {1, 2} and the proper subset of A is C = {1,2,3,4}

The set is given as:

A = {1,2,3,4}

Subsets of a set are sets that can be found in another set

An instance of this is

B = {1, 2}

Because all the elements of set B are in set A

Proper subsets of a set are sets that contain the exact elements found in another set

An instance of this is

C = {1,2,3,4}

Because set C and set A have the same elements

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
1. y = 2x - 3

The slope is m = 2 and has a negative y-intercept of -3

2. y = -2x + 3
The slope is m = -2 and has a y-intercept of 3

3. y = 2x + 3
The slope is m = 2 and has a y-intercept of 3        

4. y = -2x - 3

The slope is m = -2 and has a y-intercept of -3

Answer:

The population mean is 19.2 to 20.8.

Step-by-step explanation:

The formula of Confidence interval is

CI = mean ± z*[tex]\frac{s}{\sqrt{n} }[/tex]

where

n = sample size

s  = Population standard deviation.

mean = Sample mean

z(α/2) = Two tailed z-value for significance level of .

Given : Confidence level = 95.44% = 0.9544

Significance level =  α = 1-0.9544 = 0.0456

Now we Use standard z-value table  

z-value for Significance level of 0.0456 :

z(α/2) = z(0.0228) = 1.99 = 2(approximately)

And we are given

n=144

s = 4.8

mean = 20

so the required Confidence interval is

CI = 20± 2*[tex]\frac{4.8}{\sqrt{144} }[/tex]

     = 20 ± 2*[tex]\frac{4.8}{12}[/tex]

      = 20 ± (0.8)

      = (20-0.8, 20+0.8 )

       = (19.2 , 20.8)

Therefore the 95.44% CI value  for the population mean of 20 is 19.2 to 20.8.

Step-by-step explanation:

they are all being multiplied by 5.

Answer:

Y = 5x

Step-by-step explanation: It is that because they are multiplying everything by 5.

The quotient when 480 is divided by -60 is 8.

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

The numbers given are 480 and -60.

Both are in opposite signs, that is one negative and other positive.

So the quotient will be negative.

Now divide 480 by 60.

Since both of the numbers contain 0 at the end, cancel it.

Then it becomes 48 divided by 6.

48 / 6 = 8

Hence the quotient is 8.

The value of f(5) for each function provided in the reference picture attached hereby with the question statement are as follows:

13. f(5) = 21

14. f(5) = -12

15. f(5) = 20

16. f(5) = (-1/2)

17. f(5) = (-9)

18. f(5) = 4

As per the reference picture attached hereby with the question statement, we are provided with 6 functions.

We are required to find the value of f(5) for each function.

To solve this question, we simply have to replace the the variable of individual functions with 5 and then, perform the operations as per the function to obtain our desired answer.

Starting with [tex][f(x)=6+3x][/tex], substituting (x = 5) in the equation, we will get,

[tex]f(5)=6+(3*5)\\or, f(5)=6+15\\or,f(5)=21[/tex]

Substituting (x = 5) in the second function [tex][f(x)=-2(x+1)][/tex], we get,

[tex]f(5)=-2(5+1)\\or, f(5)=-2(6)\\or,f(5)=-(2*6)\\or, (5)=-12[/tex]

Substituting (x = 5) in the third function [tex]f(a)=[3(a+2)-1][/tex], we get,

[tex]f(5)=[3(5+2)-1]\\or, f(5)=[(3*7)-1]\\or,f(5)=(21-1)\\or,f(5)=20[/tex]

Substituting (x = 5) in the fourth function [tex][f(h)=(\frac{-h}{10})][/tex], we get,

[tex]f(5)=(\frac{-5}{10})\\ or,f(5)=\frac{-1}{2}[/tex]

Substituting (x = 5) in the fifth function [tex]f(m)=[1-4(\frac{m}{10})][/tex], we get,

[tex]f(5)=[1-4(\frac{5}{2})]\\ or,f(5)=[1-(\frac{4*5}{2})]\\ or, f(5)=[1-(2*5)]\\or,f(5)=(1-10)\\or,f(5)=(-9)[/tex]

Finally substituting (x = 5) in the last function [tex]f(m)=[2(m-3)][/tex], we get,

[tex]f(5)=[2(5-3)]\\or,f(5)=(2*2)\\or,f(5)=4[/tex]

Answer:

x=14.08

Step-by-step explanation:

Answer:

(gof) (4) = 9

Hence, option A is true.

Step-by-step explanation:

f(x)=-x³

g(x)=|1/8x -1|

(gof) (4) = g{f(4)}

First wee need to determine f(4)

f(4)=-(4)³

    = -64

so

  (gof) (4) = g{f(4)} = g(-64)

                             =  [tex]\left|\frac{1}{8}\left(-64\right)-1\right|[/tex]

                             [tex]=\left|-\frac{1}{8}\cdot \:64-1\right|[/tex]

                             [tex]=\left|-8-1\right|[/tex]

                             [tex]=\left|-9\right|[/tex]

[tex]\mathrm{Apply\:absolute\:rule}:\quad \left|-a\right|=a[/tex]

                             [tex]=9[/tex]        

Thus,

(gof) (4) = 9

Hence, option A is true.

Step-by-step explanation:

Let x represent the number of people.

13x = 52

Answer:

y= 35x + 8

Step-by-step explanation:

the $35 is an hourly charge so it goes with x and the $8 is a one time charge so it just gets added on

The required function is y = 35x + 8 to model the cost, y, to rent fishing gear and a boat for x hours.​

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

We have been given that a fishing shop charges $8 to rent fishing gear and $35 per hour to rent a boat.

According to the given situation, we can write the function as:

⇒  y = 35x + 8

Here the $35 is an hourly rate, so it corresponds to x, and the $8 is a one-time charge, so it is simply put on.

Therefore, the required function is y = 35x + 8 to model the cost, y, to rent fishing gear and a boat for x hours.​
