Determine the point estimate of the population mean and margin of error for the confidence interval. Lower bound is 17 ​, upper bound is 25. The point estimate of the population mean is:_______ The margin of error for the confidence interval is:_______

Answers

Answer 1

Answer:

Population mean = 21

Margin of error = 4

Step-by-step explanation:

Given that

Lower bound of the population is 17

Upper bound of the same population is 25

The population mean, x-bar is calculated by saying

x-bar = (lower bound + upper bound)/2

x-bar = (17 + 25)/2

x-bar = 42/2

x-bar = 21

Margin of error for the confidence interval is gotten by

E = (upper bound - lower bound)/2

E = (25 - 17)/2

E = 8/2

E = 4

Thus, the mean is 21, while the error is 4

x=4

Answer:

x = 4

Step-by-step explanation:

Vertically opposite angles are equal

        27x + 2 = 26x + 6              {Subtract 26x from both sides}

27x -26x + 2 = 6

           x  + 2 = 6               {Subtract 2 form both sides}

                  x = 6 - 2

x = 4

julie opens a bank account with $500.she deposits $60 each month.write a function that represents the amount that is in julies account after x months

Answers

Answer:

[tex]f(x) = 500 + 60x[/tex]

Step-by-step explanation:

Given

[tex]Ope\ ning\ Balance = 500[/tex]

[tex]Deposits = 60[/tex] --- monthly

Required

Write as a function

Represent the number of months with x and the balance at any month with f(x)

f(x) is calculated as thus:

Opening Balance + Deposits * Number of Months

So, we have:

[tex]f(x) = 500 + 60 * x[/tex]

[tex]f(x) = 500 + 60x[/tex]

Hence, the function that represents the scenario is

[tex]f(x) = 500 + 60x[/tex]

An equilateral triangle has sides of equal length. Find the dimensions of an equilateral triangle with a perimeter of 45 inches. P=4s

Answers

Answer:

P= 4s

P= 4(45)

solve for x

Answers

Answer:

x = - 13/29 OR x = - -0.44827586

Step-by-step explanation:

We use PEMDAS to evaluate the equation.

P stands for parenthesis. In this case we distribute the 8 to the equation in parenthesis.

8(-8x - 6)

-64x - 48 = -6x - 22 we will move the terms to their proportional sides

-64x + 6x = 22 + 48 (remember we do the opposite equation to move to the other side of the equals to sign)

-58x = 70 we divide both sides by -58 to isolate x

x = - 13/29 OR x = - -0.44827586

American Airlines charges $270 for a flight to Denver and $50 for each piece of luggage. Delta Airlines charges $330 for a flight and only $30 for each piece of luggage. Which inequality shows the number of pieces of luggage that need to be checked for American Airlines to cost more than Delta Airines for a flight to Denver?
F 270 + 50x > 330 + 30x
G 270x +50 > 330x + 30
H 270x + 50 < 330x +30
J 270 +50x > 330 + 30x​

Answers

Answer:

J; 250 + 50x > 330 + 30x

Step-by-step explanation:

Since we don't have to worry about formatting the numbers to slope-intercept form, we can start the process of elimination.

First, we can disregard G and H because both have the x in the wrong place:

—> F 270 + 50x ≥ 330 + 30x

—> G 270x + 50 > 330x + 30

—> H 270x + 50 < 330x +30

—> J  270 + 50x > 330 + 30x​

We're looking for 270 + 50x > 330 + 30x.

Next, we determine which symbols are correct.  Since the question is only asking for when American Airlines would be more expensive, not when it would be just as much or more, we can get rid of F.

—> F  270 + 50x ≥ 330 + 30x

—> J 270 +50x > 330 + 30x

We finally have our answer, J.
