A carnival game has 160 rubber ducks floating in a pool. The person playing the game takes out one duck and looks at it.

If there’s a red mark on the bottom of the duck, the person wins a small prize.

If there’s a blue mark on the bottom of the duck, the person wins a large prize.

Many ducks do not have a mark.

After 50 people have played the game, only 3 of them have won a small prize, and none of them have won a large prize.

Estimate the number of the 160 ducks that you think have red marks on the bottom.

The missing side lengths for triangle ABC are 4, 4√3, and 8.

Based on the given information, it seems that the triangle is a right-angled triangle with angles of 30°, 60°, and 90°. Let's find the missing side lengths for triangle ABC using the given lengths and angles.
Identify the triangle type.
Since we have angles of 30°, 60°, and 90°, we are working with a 30-60-90 right-angled triangle.
Determine the ratio of side lengths.
In a 30-60-90 triangle, the ratio of the sides is 1:√3:2.
Find the corresponding side lengths.
Using the given lengths and the 1:√3:2 ratio, we can determine the side lengths for triangle ABC:
- If the shortest side (opposite the 30° angle) is 4, then the other sides would be 4√3 (opposite the 60° angle) and 8 (hypotenuse, opposite the 90° angle).

2) Brianna's average monthly expenses are $3,135.

3) Brianna's total monthly cash flow is -$1,295.

The cash flow refers to the cash inflows and cash outflows.

Cash inflows are incomes while cash outflows are expenses.

Answer:

Let x be the number of bottles of water that Yui buys, and let y be the number of sports drinks she buys.

Since Yui buys a total of 6 bottles of water and sports drinks, we know that:

x + y = 6

We also know that each bottle of water costs $1.50 and each sports drink costs $2.50, and that Yui spends a total of $10. Therefore, we can write another equation based on the total cost:

1.5x + 2.5y = 10

We now have a system of two equations with two variables:

x + y = 6

1.5x + 2.5y = 10

To solve for x and y, we can use substitution. Rearranging the first equation, we get:

x = 6 - y

Substituting this expression for x into the second equation, we get:

1.5(6 - y) + 2.5y = 10

Expanding and simplifying, we get:

9 - 1.5y + 2.5y = 10

Combining like terms, we get:

y = 2

Substituting this value of y back into the equation x + y = 6, we get:

x + 2 = 6

Solving for x, we get:

x = 4

Therefore, Yui buys 4 bottles of water and 2 sports drinks.

Using the defined iterative process, xₙ ₊ ₁ = 4xₙ(3 - xₙ) with x₀ = 5,

The value of x₁ is -40

The value of x₂ is -6880

From the question, we are to compute the values of x₁ and x₂ from the given iterative process

The definition of the iterative process is:

xₙ ₊ ₁ = 4xₙ(3 - xₙ)

From the given information,

x₀ = 5

To determine the value of x₁, we will substitute n = 0

xₙ ₊ ₁ = 4xₙ(3 - xₙ)

x₀ ₊ ₁ = 4x₀(3 - x₀)

x₁  = 4x₀(3 - x₀)

Substitute x₀ = 5

x₁  = 4(5)(3 - 5)

x₁  = 20(-2)

x₁  = -40

To determine the value of x₂, we will substitute n = 1

xₙ ₊ ₁ = 4xₙ(3 - xₙ)

x₁ ₊ ₁ = 4x₁(3 - x₁)

x₂ = 4x₁(3 - x₁)

Substitute x₁  = -40

x₂ = 4(-40)(3 - (-40))

x₂ = -160(43)

x₂ = -6880

Answer:

C. complementary

Michel-Eugène Chevreul discovered that placing complementary colors next to each other can create the greatest contrast and vibrancy in color perception. This is because complementary colors are located opposite each other on the color wheel and, when placed side by side, they enhance each other and create a strong visual impact. For example, placing yellow next to violet or blue next to orange can create a dynamic and eye-catching effect. In contrast, placing tertiary colors (colors made by mixing primary and secondary colors) or arbitrary colors next to each other may not create as much contrast or visual interest. Overall, understanding color theory and the relationships between different colors can be helpful for creating visually appealing designs, artworks, or other color-based projects.

The required, experimental probability that a team will consist of two girls and a boy is 0.33. Option A is correct.

To find the experimental probability that a team will consist of two girls and a boy, we need to count the number of times that Kayla got a team with two girls and one boy and divide that by the total number of trials.

So, out of 50 trials, there were 17 trials where the team had two girls and one boy. Therefore, the experimental probability is:

Answer: 13 7/8

Step-by-step explanation:

The area of this​ trapezoid is 14.42 square yards.

To compose the trapezoid into a parallelogram, we need to add a triangle to the top of the trapezoid, so that the top and bottom sides are parallel. The area of the triangle is equal to half the product of the base and height.

First, we need to convert the mixed numbers to improper fractions:

Base 1: 6 1/3 yd = 19/3 yd

Base 2: 8 1/5 yd = 41/5 yd

Height: 3 3/4 yd = 15/4 yd

The length of the top side of the triangle is equal to the difference between the two bases:

Top side = 41/5 - 19/3 = (123 - 95)/15 = 28/15

Now we can calculate the area of the triangle:

Triangle area = (1/2) x (28/15) x (15/4) = 7/4

The trapezoid can now be composed into a parallelogram, with base 1 as one side and base 2 as the other side. The height of the parallelogram is the same as the height of the trapezoid, which is 15/4 yd.

The area of a parallelogram is equal to the product of its base and height, so the area of the trapezoid is:

Parallelogram area = (19/3 + 41/5) x (15/4) = 865/60 = 14.42

Therefore, the area of the trapezoid is 14.42 square yards.

The measure of the angle of the triangle ∠BCD = 13°

Given data ,

Let the triangle be represented as ΔBCD

Now , in triangle BCD, we are given the following angle measurements:

angle CDE = (9x - 12)°

angle BCD = (2x + 3)°

angle DBC = (3x + 5)°

From the exterior angle theorem , we get

∠CDE = ∠BCD + ∠DBC

On simplifying , we get

9x - 12 = 2x + 3 + 3x + 5

9x - 12 = 5x + 8

Subtracting 5x on both sides and adding 12 , we get

4x = 20

Divide by 4 on both sides , we get

x = 5

The expression (7√98 + 3√242) divided by 6√50 simplifies to the fraction of 4/3.

To simplify the expression (7√98 + 3√242) ÷ 6√50, we need to rationalize the denominator. This means we need to simplify the expression in such a way that there are no radical signs in the denominator. To do this, we can use the fact that the product of a radical and its conjugate is a rational number.

First, let's simplify the terms under the radicals by factoring out the perfect squares:

√98 = √(49*2) = 7√2

√242 = √(121*2) = 11√2

Now the expression becomes:

(7√2 + 311√2) ÷ (6√(252))

= (7√2 + 33√2) ÷ (6*5√2)

= 40√2 ÷ 30√2

The marginal cost function is given as c(x) = 14 / √x, where x is the number of units produced.

To find the total cost of producing the first 25 units, we need to integrate the marginal cost function from x=0 to x=25, as follows:

Total cost = ∫₀²⁵ 14 / √x dx

We can use integration by substitution to solve this integral. Let u = √x, then du/dx = 1/(2√x), and dx = 2u du. Substituting these into the integral, we get:
