The random probability of event X, wheel stopping on a white slice is 0.9 while the probability of not X, wheel stopping on Grey slice is 0.1

Total numbers on wheel = total possible outcomes

= {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Grey colored portion = {3}

White colored portion = {1, 2, 4, 5, 6, 7, 8, 9, 10}

X = Event that wheel stops on a white slice

P(X) = number of white slices ÷ total number of slices

P(X) = 9 / 10 = 0.9

P(not X) = 1 - P(X)

P(not X) = 1 - 0.9 = 0.1

After filling up the gravy dish, Bernice will have 410 ml of gravy left in the pot.

We have,

Determine the amount of gravy needed to cover the turkey:

We know that Bernice made 950 ml of gravy to go with a 5 kg turkey.

There are different ways to estimate how much gravy is needed to cover a turkey, but a common rule of thumb is to allow for about 1/2 cup (or 120 ml) of gravy per serving.

Assuming that the turkey will be served to about 8 people, we can estimate that Bernice will need:

We can write it as an expression:

= 120 ml/serving x 8 servings

= 960 ml of gravy

This means that Bernice made just enough gravy to cover the turkey and have a little bit left over.

Calculate how much gravy will be left in the pot:

We know that the capacity of the gravy dish is 540 ml.

If Bernice fills up the gravy dish with gravy, she will have.

= 950 ml - 540 ml

= 410 ml of gravy left in the pot.

Therefore,

After filling up the gravy dish, Bernice will have 410 ml of gravy left in the pot.

The volume of the rectangular prism is 97.5 cubic yards. (option b).

In this case, the rectangular prism has dimensions of 3 yards by 5 yards by 6 and one-half yard. To find its volume, we need to multiply these three dimensions together.

First, we need to convert the height of the prism to yards, as the other two dimensions are already given in yards. We know that 1 yard is equal to 3 feet, so 6 and one-half yards is equal to (6 x 3) + (1/2 x 3) = 18 + 1.5 = 19.5 feet. We then convert this to yards by dividing by 3, which gives us 6.5 yards.

Now, we can find the volume of the rectangular prism by multiplying the three dimensions together:

Volume = length x width x height

Volume = 3 yards x 5 yards x 6.5 yards

Volume = 97.5 cubic yards

Hence the correct option is (b).

a) The range of chest measurements contains 68% which falls closest to the mean is between 38 inches and 42 inches

b) The chest measurements for the 2.5% of the men with the smallest chest measurements in the population to be approximately 36 inches

Given data ,

The Empirical rule, also known as the 68-95-99.7 rule, is a statistical guideline that describes the approximate distribution of data in a normal distribution.

Approximately 68% of the data falls within one standard deviation (σ) of the mean (μ)

Approximately 95% of the data falls within two standard deviations of the mean (μ ± 2σ)

Approximately 99.7% of the data falls within three standard deviations of the mean (μ ± 3σ)

It would be within one standard deviation of the mean for the range of chest measures that accounts for 68% of the data and is closest to the mean. Since the standard deviation is 2 inches and the mean chest measurement is 40 inches, we can get the range as follows:

Mean - 1 standard deviation = 40 - 2 = 38 inches

Mean + 1 standard deviation = 40 + 2 = 42 inches

b)

We may look at the bottom end of the distribution to obtain the chest dimensions for the 2.5% of males with the smallest chest measurements in the population. The empirical rule states that 2.5% or less of the data goes outside of two standard deviations of the mean. So, using the following formula, we can get the chest size of the 2.5% of men:

Mean - 2 standard deviations = 40 - 2(2) = 36 inches

Jasica should invest $878.84 per month in a sinking fund with 3% interest compounded monthly to accumulate $83,000 in 7 years.

To determine how much Jasica should make in a sinking fund, we can use the formula for the future value of an annuity due:

FV = PMT x [tex](((1 + r/n)^nt[/tex] - 1) / (r/n))

Where:

FV = future value

PMT = monthly payment

r = interest rate (as a decimal)

n = number of compounding periods per year

t = number of years

In this issue, we are solving for PMT.

Given:

FV = $83,000,

r = 0.03 (3% expressed as a decimal),

n = 12 (monthly compounding),

t = 7 years.

Plugging in the values, we have:

$83,000 = PMT x [tex](((1 + 0.03/12)^(12*7)[/tex] - 1) / (0.03/12))

Simplifying:

$83,000 = PMT x (94.4523)

PMT = $83,000 / 94.4523

PMT = $878.84 (rounded to the nearest cent)

Therefore, Jasica should invest $878.84 per month in a sinking fund with 3% interest compounded monthly.

In Mathematics and Geometry, an inverse function simply refers to a type of function that is obtained by reversing the mathematical operation in a given function (f(x)).

In this exercise, you are required to determine the inverse of the function f(x). This ultimately implies that, we would have to swap (interchange) both the independent value (x-value) and dependent value (y-value) as follows;

Answer:

Many buildings and structures around us involve transformed shapes in their design. For example, a skyscraper may have a rectangular base that is transformed into a triangular shape as it reaches higher levels. This transformation is achieved by using a technique called tapering, where the building's width gradually decreases as it goes up, resulting in a triangular shape at the top.

Another common transformation is the use of rotation, which is seen in the design of many cylindrical structures like water towers or chimneys. The cylinder is rotated around its axis to create a three-dimensional shape.

These transformed shapes contribute to the design of the object in many ways. For instance, the triangular shape of a skyscraper's top helps to reduce wind resistance and improve stability. Tapering also allows more sunlight to reach street level and reduces the impact of shadows on the surrounding area. In the case of cylindrical structures, rotation can provide structural stability while minimizing the amount of material used in the construction.

Overall, the use of transformed shapes in building and structure design helps to achieve specific aesthetic and functional goals, from stability to energy efficiency.

Step-by-step explanation:

Answer:

The Empire State Building is a skyscraper in Midtown Manhattan, New York City, on Fifth Avenue between West 33rd and 34th Streets. It has a roof height of 1,250 feet (381 m), and with its antenna spire included, it stands a total of 1,454 feet (443.2 m) high. Its name is derived from the nickname for New York, the Empire State.

The Empire State Building is an example of a transformed shape. The original shape is a square, but the architects transformed it into a triangle by adding a spire to the top. The spire adds height and visual interest to the building. It also helps to make the building more stable.

The use of transformed shapes in the design of the Empire State Building contributes to its overall aesthetic appeal. The building is both visually striking and structurally sound. It is a testament to the skill and ingenuity of the architects who designed it.

Here are some other examples of transformed shapes in buildings and structures:

* The Parthenon in Athens, Greece, is a rectangular building with a triangular pediment at each end. The pediments are decorated with sculptures that depict scenes from Greek mythology.

* The Eiffel Tower in Paris, France, is a wrought iron lattice tower that was built for the 1889 World's Fair. The tower is a transformed shape of a regular hexagon.

* The Gateway Arch in St. Louis, Missouri, is a stainless steel arch that spans the Mississippi River. The arch is a transformed shape of a catenary curve.

These are just a few examples of the many ways that transformed shapes are used in the design of buildings and structures. Transformed shapes can be used to add visual interest, create a sense of movement, or simply to make a building more structurally sound.

The solution to the simultaneous equation is x = 6 and y = 3.

To solve this system of equations, we can use the method of elimination. First, we want to eliminate one of the variables, either x or y. In this case, it is easiest to eliminate y. To do so, we can multiply the second equation by 3, which gives us:

6x + 3y = 45

6x - 6y = 18

Now, we can subtract the second equation from the first:

6x + 3y - (6x - 6y) = 45 - 18

Simplifying this expression, we get:

9y = 27

Dividing both sides by 9, we get:

y = 3

Now that we know the value of y, we can substitute it into either equation to find the value of x. Let's use the first equation:

6x + 3y = 45

6x + 3(3) = 45

6x + 9 = 45

Subtracting 9 from both sides, we get:

6x = 36

an = a1 * r^(n -1)

So, we have

a2 = a1 * r = 36

a7 = a1 * r^6 = 128/27

Divide the equations

r^5 = (128)/(27 * 36)

This gives

r = [(128)/(972)]^1/5

So, we have
