A large restaurant chain is curious what proportion of their customers in a given day are new customers. They are thinking of taking a sample of either n=50 or n=100 customers and building a one-sample z interval for a proportion using the data from the sample. Assuming the sample proportion is the same in each sample, what is true about the margins of error from these two samples?

Answer:

7/13

Step-by-step explanation:

The difference that is closest to zero will indicate the fraction that is closest to 1/2. Since 1/26 is closest to zero, 7/13 is closest to 1/2.

Answer:

232.5 cm²

Step-by-step explanation:

232.5

The required area of the regular pentagon with an 8-cm apothem and 11.6-cm sides is 232 cm².

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Here,
To find the area of a regular pentagon, we can use the formula:

Area = (1/2) x Apothem x Perimeter

where Apothem is the distance from the center of the pentagon to the midpoint of any side, and Perimeter is the sum of the lengths of all the sides.

In this case, the apothem is given as 8 cm, and the length of each side is given as 11.6 cm.

To find the perimeter, we can simply multiply the length of one side by 5:

Perimeter = 5 x 11.6 cm = 58 cm

Now, we can plug in these values into the formula:

Area = (1/2) x 8 cm x 58 cm

Area = 232 cm²

Therefore, the area of the regular pentagon with an 8-cm apothem and 11.6-cm sides is 232 cm².

Answer:

A

Step-by-step explanation:

The volume (V) of water in the tank is calculated as

V = lbh (l is length, b is breadth and h is height )

Here l = 80, b = 40 and h = 50 , then

V = 80 × 40 × 50 = 160000 cm³

V ( in litres) = 160000 ÷ 1000 = 160 litres , then

number of times = 160 ÷ 10 = 16

Answer:

2/11 or

0.181818

Step-by-step explanation:

Because 8/11 in precent form is 72%

So, 72÷4= 18.

If you put 18 in decimal form, it will be:

.18

For the fraction answer, .18 will be 0.22

And 0.22 in fraction form will be 2/11.

So those are your answers.

I hope this helped      :)

The division of the equation A = ( 8/11 ) / 4 is A = 0.1818..

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the first fraction be represented as p = ( 8/11 )

Let the second fraction be q = 4/1

Now , the equation is A = 8/11 divided by 4

On simplifying , we get

A = ( 8/11 ) / 4

A = ( 8/44 )

A = 0.181818181..

Therefore , the value of A is a recurring decimal number

Hence , the equation is A = 0.181818..

Just took the quiz

Answer:

10 units^2

Step-by-step explanation:

The ordered pair does not lie on the graph of the exponential function

is (12, 0).

Option A is the answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To check whether an ordered pair lies on the graph of the exponential function f(x) = [tex]3(1/4)^x,[/tex]

We need to substitute the values of x and y into the function and see if the equation holds true.

A. (12, 0)

Substituting x = 12 and y = 0 into the function, we get:

[tex]f(12) = 3(1/4)^{12} = 0.000002861[/tex]

This does not equal y = 0, so (12, 0) does not lie on the graph of the function.

B. (-2, 48)

Substituting x = -2 and y = 48 into the function, we get:

[tex]f(-2) = 3(1/4)^{-2} = 48[/tex]

This does not equal y = 48, so (-2, 48) does lie on the graph of the function.

C. (2, 3/16)

Substituting x = 2 and y = 3/16 into the function, we get:

[tex]f(2) = 3(1/4)^2 = 3/16[/tex]

This equals y = 3/16, so (2, 3/16) does lie on the graph of the function.

D. (0, 3)

Substituting x = 0 and y = 3 into the function, we get:

[tex]f(0) = 3(1/4)^0 = 3[/tex]

This equals y = 3, so (0, 3) does lie on the graph of the function.

Therefore,

The ordered pair does not lie on the graph of the exponential function

is (12, 0).
