Yes, data provide convincing evident that contest has increased participation.

We have,

H₀: p = 0.12

Hₐ: p > 0.12

So, z = (p' - p)/ (√pq/n)

z = 1/6 - 0.2/ √(0.12 x 0.88) /210

When a tank is 1/2 full it contains 45 liters of water, the area of the base is 450 cm², the height of the tank is 200 cm.

Let the height of the tank be 'h' cm. Since the tank is half full, it contains 45 liters of water which is equal to 45,000 cubic cm.

The volume of water in the tank is given by:

Volume of water = (1/2) x (450 cm²) x (h cm)

Since the volume of water is 45,000 cubic cm, we can set up the following equation:

(1/2) x (450 cm²) x (h cm) = 45,000 cubic cm

Simplifying, we get:

225h = 45,000

h = 200 cm

In this case, the area of the base is given in square centimeters, so we must use cubic centimeters for the volume of water. Also, we converted the liters to cubic centimeters by multiplying by 1000 since 1 liter is equal to 1000 cubic centimeters.

The surface area of the figure is  174.7 sq. ft.

Consider the bottom rectangular surface of the figure.

The dimensions of the bottom rectangular surface are: length = 10 ft and width = 3 ft

Using the formula for the area of rectangle, the area of bottom surface of the figure would be,

A₁ = length × width

A₁ = 10 × 3

A₁ = 30 sq. ft.

The dimensions of the right rectangular surface are length = 9 ft and width = 3 ft

Using the formula for the area of rectangle, the area of bottom surface of the figure would be,

A₂ = length × width

A₂ = 9 × 3

A₂ = 27 sq. ft.

The dimensions of the left rectangular surface are length = 11 ft and width = 3 ft

Using the formula for the area of rectangle, the area of bottom surface of the figure would be,

A₃ = length × width

A₃ = 11 × 3

A₃ = 33 sq. ft.

There area two parallel triangular suface with dimensions: base = 11 ft and height = 7.7 ft

Using the formula of the area of triangle the surface area of these two triamgular surfaces would be,

A₄ = 2 × 1/2 × base × height

A₄ = base × height

A₄ = 11 × 7.7

A₄ = 84.7 sq. ft.

So, the total surface area of the figure would be,

A = A₁ + A₂ + A₃ + A₄

A = 30 + 27 + 33 + 84.7

A = 174.7 sq. ft.

This is the required surface area of the figure.

where r = 12/2 = 6 in

height of cylinder (h) = 13 - 6 = 7 in

Answer: Option C.

The volume of a cylinder is given by the formula V = πr^2h, where r is the radius and h is the height.

Given that the diameter of the container is 24 ft, the radius (r) would be half of that, which is 12 ft.

The depth of the container (h) is given as 4 ft.

Plugging in these values into the formula, we get:

V = π(12^2)(4)

V = 3.14(144)(4)

V = 1808.6 cubic feet (rounded to the nearest tenth)

So, the storage container can hold approximately 1808.6 cubic feet of wood, rounded to the nearest tenth.

Kenyon could make a total of 7 bouquets.

Step-by-step explanation:

To find the greatest number of bouquets we need to find GCF.

We need to find GCF for 21 and 28.

The factors of 21 are: 1,3,7, and 21.

The factors of 28 are: 1,2,4,7,14, and 28

1 and 7 are the common factors between 21 and 28.

From the factors, the greatest common factor is 7.

The evaluated speed of P is 54.5 m s¯¹, under the condition that two forces F₁ and F₂ act on a particle P. The force F₁ is given by F₁ = (-i + 2j) N and F₂ acts in the direction of the vector (i + j).

To evaluate the speed of particle P when t = 3 seconds, we can apply the equations of motion formulas to calculate the velocity if the acceleration and initial velocity values are already given.
The formula can be derived :
v = u + at
Here,
v =  final velocity of the particle,
u = initial velocity of the particle,
a = acceleration acting on the particle
t = time taken.
It is known to us that the acceleration of P is (3i + 9j) ms² and at time t = 0, the velocity of P is (31 -22j) m s¯¹. We can evaluate the initial velocity u by taking the magnitude of (31 -22j) that is
√(31² + (-22)²)
= 39.051 m s¯¹.
Now we can staging all values into the formula
v = u + at
v = 39.051 + (3i + 9j) × 3
v = 39.051 + (9i + 27j)
v = (39.051 + 9)i + (27)j
v = 48.051i + 27j
Then, when t = 3 seconds, the speed of particle P is √(48.051² + 27²)
= 54.5 m s¯¹.

Trigonometric ratio is used to show the relationship between the sides of a triangle and its angles.

Let h represent the height of the kite. Hence, using trigonometric ratios:

sin(30) = h / 95

h = 47.5 feet

Therefore the height of the kite is 63.40 feet.

The domain can be written as follows:

R - {x = n*12pi or m*4pi | n, m ∈ Z}

where pi = 3.14 and R is the set of real numbers.

Here we want to find the domain of the function:

y = tan(x/8)

The tangent is the quotient between the cosine and the sine, then we will get:

sin(x/8)/cos(x/8)

The problems of the tangent are all the values that make the denominator equal to zero, then we need to remove these.

The zeros are:

cos(x/8) = 0

We know that cos(pi/2) = cos(3pi/2)  = 0

Then:

x/8 = pi/2

x = 4pi

x/8 = 3pi/2

x = 12pi

As per the unitary method, each piece is 3.25 meters long by dividing the total length of the ribbon by the number of pieces.

Larry has cut a ribbon into 8 equal pieces. The total length of the ribbon is 26 m. We need to find out the length of each piece of the ribbon.

To do this, we can use the unitary method. We know that the ribbon is divided into 8 equal pieces, so each piece is 1/8th of the total length of the ribbon.

Therefore, we can find the length of each piece by dividing the total length of the ribbon by 8:

Length of each piece = Total length of ribbon / Number of pieces

Length of each piece = 26 m / 8

Length of each piece = 3.25 m

So, each piece of the ribbon is 3.25 meters long.

Given data ,

The Return on Equity (ROE) is calculated as the ratio of Net Income to Equity. Net Income is the EBIT (earnings before interest and taxes) minus the taxes, and Equity is the total assets minus the debt.

EBIT = $140,000

Tax rate = 25%

Total assets = $700,000

Debt = 0% (since the project is financed with 100% equity)

Taxes = Tax rate x EBIT

Taxes = 0.25 x $140,000

Taxes = $35,000

And , the net income is

Net Income = EBIT - Taxes

Net Income = $140,000 - $35,000

Net Income = $105,000

Since we can't have a fractional number of lines, Citywide can sign up for a maximum of 1 line and still stay within their budget.

Let's start by calculating the total amount Citywide pays for their telephone costs without the federal excise tax. We can do this by subtracting the 3% tax from the total budget:

$190 / 1.03 = $184.47

The $96 budget plan includes 4,000 minutes, which means that each minute costs:

$96 / 4,000 = $0.024

If Citywide wants to stay within their budget, they need to make sure that the total cost of the lines they sign up for plus the federal excise tax is less than or equal to $190.

Let's represent the number of lines Citywide signs up for as "n". The total cost of the lines plus tax can then be represented as:

n * $96 * 1.03

Setting this expression less than or equal to $190, we get:

n * $96 * 1.03 <= $190

Simplifying, we get:

n <= $190 / ($96 * 1.03)

n <= 1.945
