A bag contains: • 2 white marbles • 3 brown marbles • 4 purple marbles • 6 orange marbles A marble will be drawn from the bag and replaced 75 times. What is a reasonable prediction for the number of times a brown or purple marble will be drawn?

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.

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).

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:

x=4.8

This here you use Pythagorean Theorem.

Step-by-step explanation:

a^2+b^2=c^2

The longest side is c. And the two legs are a and b.

So it'd be 11^2+x^2=12^2

121+x^2=144

Subtract 121 from both sides.

x^2=23

Then take the √ of x^2 and 23

So √x^2=√23

x=4.8

Answer:

Upper Control Limit = 6.03 oz

Lower Control Limit = 5.97 oz

Step-by-step explanation:

Given - A process that makes chocolate candy bars has an output that is normally distributed with a mean of 6 oz. and a standard deviation of .01 oz.

To find - Determine three sigma control limits for an x-bar (mean) chart assuming a sample size of 10.

Proof -

Given that,

μ = 6

σ = 0.01

Z value for 3 sigma process = 3

Now,

Control limits are - μ ± Zσ

Now,

Upper Control limit (UCL) = μ + Zσ

And

Lower Control limit (LCL) = μ - Zσ

Now,

UCL = 6 + 3( 0.01 )

        = 6 + 0.03

       = 6.03

⇒UCL =6.03 oz

Now,

LCL = 6 - 3( 0.01)

      = 6 - (0.03)

      = 6 - 0.03

      = 5.97

⇒LCL =5.97 oz

∴ we get

Upper Control Limit = 6.03 oz

Lower Control Limit = 5.97 oz

$1.30

Step-by-step explanation:

What you do is add the original 65 cents to the additional 65 cents that were shown to get 130. Since it's more than 100 you make it into dollars, so the final answer is $1.30.

Answer:

$1.30

Step-by-step explanation:

You need to know how coins look like. The middle one is a quarter and the other four are dimes. We know that quarters are worth 25 cents and dimes are worth 10 cents. Because there are 4 dimes, you do 4x10 which is equal to 40. We know that there is only one quarter so we do 40+25 which is equal to 65. Therefore, the tip is 65 cents Then, you add 65 cents to 65 cents again because Faaz had already put 65 cents there. 65+65 is equal to 130. 130 is equal to 1 dollar and 30 cents. Therefore, the tip is $1.30
