The average price of a ticket originating in Chicago using United Airlines is $1212.40.

Step-by-step explanation:

The data provided is as follows:

                    United Air France British

Chicago         1063              1314          1442

                      1299             1493           1413

                       995             1443          1063

                      1299             1577          1442

                      1406             1314          1575

London         1015             1374          1603

                       856              977           1531

                       802             1043          1079

                       850             1070           807

                       935             1428           870

The data for the price of a ticket originating in Chicago using United Airlines is:

Chicago = {1063, 1299, 995, 1299, 1406}

Compute the average price as follows:

[tex]\bar X=\frac{1}{n}\sum X[/tex]

   [tex]=\frac{1}{5}\times [1063+1299+995+1299+1406]\\\\=\frac{6062}{5}\\\\=1212.40[/tex]

Thus, the average price of a ticket originating in Chicago using United Airlines is $1212.40.

Step-by-step explanation:

The perimeter of a rectangle is the sum of all the sides and the width sides are equal, as well as the two length sides.

For this problem that would mean that two sides are equal to BC and two sides are equal to AB.

Since the perimeter (P)  is equal to 60 , we can write:

P = 2 * BC + 2 * AB

We can substitute the expressions we are given for AB and BC and 60 for the perimeter:

60 =  2 (2z + 3 ) + 2 (3z + 2)

Using the distributive property and combining like terms, we can find the value of the variable , z:

60 = 4z + 6 + 6z + 4

60 = 10z + 10

Subtract 10 from both sides of the equation:

60 - 10 = 10z + 10 -110

50 = 10z

Divide both sides of the equation by 10:

50/10 = 10z/10

5 = z

Since z = 5, then BC is 2z + 3 or 2*5 + 3

BC = 13

Answer:

5/21

You flip the number 3 which will be "1/3", then you multiply that by 5/7 and you get 5/21

Given expression;

             We are to divide 5/7 by 3;

  Now;

                          [tex]\frac{\frac{5}{7} }{3}[/tex]  

        So;

                    [tex]\frac{5}{7}[/tex]  divided by 3

                 = [tex]\frac{5}{7} x \frac{1}{3}[/tex]

Answer:

None of the options are correct, but I got g(x)=1/2x+2.

Step-by-step explanation:

You start with the equation. You first need to change f(x) to y, and switch the x and y values. After this, your equation would be x=2y-4. Then, you need to icolate the y value, and to do that you first cancel out the four by adding it to both sides, and now your equation should be x+4=2y. The second step in icolating the y value is dividing everything in the equation by two. Now that the y is icolated, you equation should be y=1/2x+2. You then change the y to be g(x), and that's how I got my answer, g(x)=1/2x+2. You should ask your teacher about this, becuase from my calculations, none of the given responses would be correct. Sorry if that doesn't help you at all but yeah

Answer: x => -6

Step-by-step explanation: All you gotta do is alternate the form

The solution for the given inequality is x ≥ -6.

A declaration of an order connection between two numbers or algebraic expressions, such as greater than, equal to, less than, less than, or equal to. Either questions or theorems can be used to express inequality problems, and both can be solved using methods similar to those used to solve equations. The triangle inequality, for instance, stipulates that the length of the remaining side of a triangle is more than or equal to the sum of the lengths of any two of its sides. Many of these inequalities, like the Cauchy-Schwarz inequality, are used by mathematical analysis to prove some of its most significant theorems.

Given an equation -3−4x ≤ 21.

Solve for x

-3−4x ≤ 21

add three to both sides

-4x ≤ 24

divide by -4 into both sides (signs will be changed)

x  ≥ -6

Therefore solution for the given equation in the form of inequalities is

x ≥ -6.

Answer:

the first one

The number line which can be used to find the distance between (4, -1) and (8,-1) is 1

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

[tex]D = √[(x-p)² + (y-q)²] D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

Given the points;

(x1, y1) = (4, -1)

(x2, y2) = (8, -1)

Here, we have the same values of y for both points.

This means that the line that contains both points is a horizontal line.

To find the distance, apply the formula:

[tex]d= \sqrt{(x2-x1)^{2} + (y2-y1)^{2} }[/tex]

Since they have the same y values, the number line to represent the distance between both points must have the points 4 and 8;

Hence, we have;

 [tex]d= \sqrt{(8-4)^{2}+(-1+1)^{2} }[/tex]

   [tex]d= \sqrt{4^{2} + 0^{2} }[/tex]

     d= 4

The distance between both points is 4;

Therefore, the number line that can be used to find the distance between both points is the number line in option A.

Answer:

The critical t-value for such a test given an alpha level of 0.05 is 2.26

Step-by-step explanation:

Null hypothesis : [tex]H_0:\mu = 7.5[/tex]

Alternate hypothesis :[tex]H_a:\mu \neq 7.5[/tex]

Population mean = [tex]\mu = 7.5[/tex]

Data : 10, 9, 6, 11, 13, 14, 9, 9, 9, and 10

Mean = [tex]\bar{x}=\frac{\text{Sum of all observations}}{\text{no. of observations}}[/tex]

Mean =[tex]\frac{10+9+6+11+13+14+9+9+ 9+ 10}{10}[/tex]

Mean =10

Standard deviation : [tex]\sqrt{\frac{\sum(x-\bar{x})^2}{n}}[/tex]

Standard deviation :[tex]\sqrt{\frac{(10-10)^2+(9-10)^2+(6-10)^2+(11-10)^2+(13-10)^2+(14-10)^2+(9-10)^2+(9-10)^2+(9-10)^2+(10-10)^2}{10}}[/tex]

Standard deviation s :2.144

[tex]t = \frac{x-\mu}{\frac{s}{\sqrt{n}}}t = \frac{10-7.5}{\frac{2.144}{\sqrt{10}}}t=3.687[/tex]

Df = n-1 = 10-1 = 9

T critical =[tex]t_{(df,\alpha)}=t_(9,0.05)=2.26[/tex]

T calculated > T critical

So, We failed to accept null hypothesis

Hence the critical t-value for such a test given an alpha level of 0.05 is 2.26

Answer:

The y-intercept of the equation is 100 and represents the initial studio-use fee.

Step-by-step explanation:

In this equation, our t variable (time) is the equivalent of the x-variable on a graph. This is because it is the variable that we 'change' to see its impact on y. We see how the amount of hours affects the price. So our P variable (price) is the equivalent of y on a graph. The y-intercept is where the line crosses the y-axis on a graph. At this point, x=0.

Since P is our y, and t is our x, to find the y-intercept, we simply need to make t = 0.

P = 50(0) + 100

P = 100

Therefore the y-intercept is 100.

In this context, t represents time, so even though the studio has been used for 0 hours, the price is still 100. This is because the 100 represents the initial studio-use fee, and using it for certain amounts of time adds onto the initial fee of $100. The hourly fee is represented by 50t so it costs $50 more for each hour of use.

Step-by-step explanation:

"Depreciates" means the value is getting smaller. The function that describes the situation is a decay function:

  y= a(1-r)^x

Here, a=150000, r = 0.07, and x=11. The value is predicted to be ...

  y = 150000(1 -0.07)^11 = 150000(0.93^11) = 67,515.53

Answer:

Answer is D.

Step-by-step explanation:

Which is not true?

So, lets assess the answers given to the question.

A. It is the equation of a horizontal line.

Yes, it is. Since there is only one y - value which is y = -4, we can confirm this is the y intercept, so therefore the x value is zero. But it's not the answer we're looking for.

B. It's slope is zero, yes the slope is zero. It only lists the y-intercept which confirms that the slope is 0.

C. Yes, I mean i can't really explain how. Just use desmos calculator, the graph is exactly perpendicular.

D. The line actually does cross the x-axis, -4 is the y intercept and the x value is 0, and zero is still a point. So D is the one which isn't correct making it the correct answer.
