**Unit 10: Circles, Homework 4: Inscribed Angles**
I need help doing the following questions (I would greatly appreciate this) :

Answer:

∠ A = 98°

Step-by-step explanation:

ABCD is a cyclic quadrilateral

its opposite angles sum to 180° , that is

∠ A + ∠ C = 180°

∠ A + 82° = 180° ( subtract 82° from both sides )

∠ A = 98°

The price-demand equation is [tex]p(x) = 77.88^(x/5)[/tex] rounded to two decimal places.

We know that the marginal price dp/dx at x units of demand per week is proportional to the price p. Let k be the constant of proportionality. Then, we have:

dp/dx = kp

Separating variables and integrating, we get:

∫dp/p = ∫kdx

ln|p| = kx + C

Taking exponential on both sides and using the initial condition p(0) = 100, we get:

p(x) = 100e^(kx)

Using the second condition, p(5) = 77.88, we get:

[tex]77.88 = 100e^(5k)[/tex]

Solving for k, we get:

k = ln(77.88/100)/5

Substituting this value of k in the price-demand equation, we get:

[tex]p(x) = 100e^[(ln(77.88/100)/5)x] = 100(77.88/100)^(x/5)[/tex]

Therefore, the price-demand equation is [tex]p(x) = 77.88^(x/5)[/tex] rounded to two decimal places.

a. The mean of the binomial distribution is  4.7

b. The variance of the binomial distribution is 1.1

c. The standard deviation of the binomial distribution is 1.0

Probability of success p = 0.78

Number of trials n = 6

(a) Mean of the binomial distribution:

The mean or expected value of a binomial distribution is given by np.

Therefore, the mean of this binomial distribution is:

μ = np = 6 x 0.78 = 4.68

So, the mean is 4.7 (rounded to one decimal place).

(b) Variance of the binomial distribution:

The variance of a binomial distribution is given by np(1 - p).

Therefore, the variance of this binomial distribution is:

σ^2 = np(1 - p) = 6 x 0.78 x 0.22 = 1.0608

So, the variance is 1.1 (rounded to one decimal place).

(c) Standard deviation of the binomial distribution:

The standard deviation of a binomial distribution is the square root of the variance.

Therefore, the standard deviation of this binomial distribution is:

σ = √(np(1 - p)) = √(1.0608) = 1.03

So, the standard deviation is 1.0 (rounded to one decimal place).

A rose garden is formed by rectangular and semi-circular parts. If the gardener wants to build a fence around the garden, then total 139.39 feet of fence are required.

The perimeter is defined as calculating the outer length of boundaries of shape.

We have a rose garden is formed by joining a rectangle and a semicircle, as present in above figure. We have to determine the feet of fence are required to build a fence around the garden.

From the above figure, length of rectangular part, l = 35 ft

Width of rectangular part, w = 27 ft.

Also, diameter of semi-circular part, d

= 27 ft

Radius of of semi-circular part, r = d/2

= 27/2 ft = 13.5 ft

So, the perimeter of semi-circular part, Pₛ = π × r = π × 13.5 ft

= 42.39 ft.

Here, the fence required for the rectangle shape is three sides that two long sides and one wide side. The fourth side of the width is already covered by the semi-circular part. So, the perimeter formula for the rectangle shape, Pᵣ = 2l + w. Therefore, perimeter of garden

= Pₛ + Pᵣ

= 42.39 ft + 2 × 35 ft + 27 ft

= 70 ft + 27 ft + 42.39 ft

= 139.39 ft.

Hence, required value is 139.39 feet.

The throw of the dice or the drawing of a card is known as random behavior.

Random behavior refers to events that occur by chance, without any predictability or pattern. These events cannot be influenced or controlled, and their outcomes are determined by the laws of probability. In games such as dice and card games, the outcomes are determined by random variables, such as the position of the dice or the shuffle of the deck.

Random behavior can also occur in other contexts, such as weather patterns or the stock market, where events are subject to unpredictable fluctuations. Understanding random behavior is important in many fields, including mathematics, statistics, and economics, as it can help us make informed decisions based on the probability of different outcomes.

Let's start by assigning variables to the unknowns in the problem. Let x be the number of one-dollar bills,

y be the number of five-dollar bills, and z be the number of ten-dollar bills. From the problem, we know that: x + y + z = 35 (since there are 35 bills in total) 1x + 5y + 10z = 144 (since the total amount of money is $144) z = y + 2

(since there are two more ten-dollar bills than five-dollar bills) Now we can substitute the third equation into the second equation: 1x + 5y + 10(y + 2) = 144 Simplifying: 1x + 15y + 20 = 144 1x + 15y = 124 We have two equations with two variables: x + y + z = 35 x + 15y = 124 Solving for x in the second equation: x = 124 - 15y

Substituting into the first equation: (124 - 15y) + y + (y + 2) = 35 126 - 13y = 35 -13y = -91 y = 7

Now we can find z: z = y + 2 = 9 And finally, we can find x: x = 124 - 15y = 124 - 15(7) = 19 Therefore, there are 19 one-dollar bills, 7 five-dollar bills, and 9 ten-dollar bills.

The valid reasons to use a sample instead of evaluating a much larger population are contacting the whole population would be only marginally more accurate than a sample. A sample can be chosen to validate a specific idea about the population.

Contacting the entire population would be time consuming.
1. Contacting the whole population would be only marginally more accurate than a sample: This is a valid reason because a well-designed sample can often provide an accurate estimate of the population, while using significantly fewer resources.
2. Sampling is a random process, and therefore more accurate than measuring the whole population: This statement is incorrect. A random sample can provide an unbiased estimate, but it is not necessarily more accurate than measuring the entire population.
3. A sample can be chosen to validate a specific idea about the population: This is a valid reason because sampling can be used to test hypotheses or ideas about the population without having to evaluate every member of the population.
4. Contacting the entire population would be time-consuming: This is a valid reason because sampling can save time and resources compared to attempting to gather data from every individual in a population.

The H.C.F of the polynomials x⁸ - y⁸, (x⁴ - y⁴)(x + y) is (x - y)(x + y)

The H.C.F - Highest Common Factor of two or more numbers is the highest of their common factors.

Given the polynomials x⁸ - y⁸, (x⁴ - y⁴)(x + y). To find their highest common factors, we proceed as follows.

Now, the polynomial x⁸ - y⁸ = (x⁴)² - (y⁴)²

= (x⁴ - y⁴)(x⁴ + y⁴) difference of two squares.

Also,

(x⁴ - y⁴) = (x²)² - (y²)²

= (x² - y²)(x² + y²) difference of two squares.

= (x² - y²)(x² + y²)

So,

x⁸ - y⁸ = (x⁴ - y⁴)(x⁴ + y⁴)

= (x² - y²)(x² + y²)(x⁴ + y⁴)

Also,  (x² - y²) = (x - y)(x + y)

So, substituting this into the quation, we have that

x⁸ - y⁸ =  (x² - y²)(x² + y²)(x⁴ + y⁴)

=   (x - y)(x + y)(x² + y²)(x⁴ + y⁴)

Now, the polynomial

(x⁴ - y⁴)(x + y) =  (x² - y²)(x² + y²)(x + y)

= (x - y)(x + y)(x² + y²)(x + y)

So, comparing the factors of x⁸ - y⁸ and (x⁴ - y⁴)(x + y), the H.C.F is (x - y)(x + y)

The FDA regulates that a fish consumed should contain at most 1 mg/kg of mercury. In Florida, bass fish from 52 different lakes were collected to determine if the mercury levels in the fish exceed the allowable amount.

To assess if there's enough evidence to show that fish in all Florida lakes have a higher mercury level than permitted, we will conduct a hypothesis test using the data collected.
The random variable (X) represents the average mercury level of bass fish in a sampled lake. The population parameter (μ) stands for the true mean mercury level of bass fish in all Florida lakes.
The null hypothesis (H₀) states that the average mercury level in the fish does not exceed the FDA's allowable amount, which means μ ≤ 1 mg/kg. The alternative hypothesis (H₁) claims that the average mercury level in the fish is higher than the FDA's allowable amount, which means μ > 1 mg/kg.
To determine if there is enough evidence to support H₁, we will perform a hypothesis test using the appropriate statistical test and significance level, while considering the sample size and mercury levels collected from the 52 lakes. If the test results lead to the rejection of H₀, we can conclude that there is evidence suggesting the fish in all Florida lakes have a mercury level higher than the allowable amount.

T he joint moment generating function of x and y is M(t1, t2) = (1/36)Σx=1^6Σz=1^6 e^(t1x + t2z)

Let X be the value of the first die, which takes on values {1, 2, 3, 4, 5, 6} with equal probability of 1/6 each. Let Y be the sum of the values of two dice, so Y takes on values {2, 3, ..., 12}.

The joint moment generating function of X and Y is given by:

M(t1, t2) = E[e^(t1X + t2Y)]

To compute this, we can use the law of total probability and conditioning on the value of X:

M(t1, t2) = E[e^(t1X + t2Y)]

= Σx P(X=x) E[e^(t1X + t2Y) | X=x]

= (1/6)Σx=1^6 E[e^(t1x + t2Y) | X=x]

Now we need to compute E[e^(t1x + t2Y) | X=x]. We can use the fact that the sum of two dice is the sum of two independent uniform random variables on {1, 2, 3, 4, 5, 6}:

E[e^(t1x + t2Y) | X=x] = E[e^(t1x + t2(x+Z))]

= E[e^(tx) e^(t2Z)]

= MZ(t2) e^(tx)

where Z is a uniform random variable on {1, 2, 3, 4, 5, 6} and MZ(t2) is its moment generating function, which is:

MZ(t2) = E[e^(t2Z)]

= (1/6)Σz=1^6 e^(t2z)

Substituting this back into the expression for M(t1, t2), we get:

M(t1, t2) = (1/6)Σx=1^6 E[e^(t1x + t2Y) | X=x]

= (1/6)Σx=1^6 MZ(t2) e^(tx)

= (1/6)Σx=1^6 [(1/6)Σz=1^6 e^(t2z)] e^(tx)

Simplifying the expression, we get:

M(t1, t2) = (1/36)Σx=1^6Σz=1^6 e^(t1x + t2z)

In a normal distribution, approximately 68% of the population is within one standard deviation of the mean. This can be explained by the empirical rule, which states that for a normal distribution, about 68% of the data falls within one standard deviation of the mean, about 95% falls within two standard deviations, and about 99.7% falls within three standard deviations.

The standard deviation is a measure of how spread out the data is from the mean, so if the data is normally distributed, we can use the empirical rule to estimate the proportion of the population that falls within a certain number of standard deviations from the mean.

Therefore, we can say with confidence that approximately 68% of the population falls within one standard deviation of the mean in a normal distribution.

Since we need to round the number of scoops to the nearest scoop, we can round 67.32 scoops to 67 scoops. Therefore, you'll need to add 67 scoops of drink mix to make a full batch of sports drink for the campers on a hot day.

To determine the number of scoops of drink mix needed for a full batch, we'll first need to calculate the volume of the container and convert it to gallons. The container's dimensions are 1 foot by 1.5 feet by 3 feet.
Step 1: Calculate the volume of the container.
Volume = length × width × height
Volume = 1 ft × 1.5 ft × 3 ft
Volume = 4.5 cubic feet
Step 2: Convert the volume to gallons.
1 cubic foot is equivalent to 7.48 gallons, so we'll multiply the volume in cubic feet by the conversion factor.
4.5 cubic feet × 7.48 gallons/cubic foot ≈ 33.66 gallons
Step 3: Calculate the number of scoops of drink mix needed.
You must add two scoops of drink mix for each gallon of water.
33.66 gallons × 2 scoops/gallon ≈ 67.32 scoops

The vector function r(s) is t = s/a, the direction of motion T(s) explicitly is r'(t) = a and the length of the  curve r(t) = ecos(t)i + et sin(t)j + e'k  is given by curvature  r = [tex]\frac{||T'(t)||}{||r'(t)||}[/tex] = 1/a.

Curvature is any of many closely related geometric notions in mathematics. Curvature is intuitively defined as the amount a curve deviates from being a straight line or a surface deviates from being a plane. The most common example of a curve is a circle, which has a curvature equal to the reciprocal of its radius. Smaller circles bend more sharply, resulting in more curvature.

The curvature of a differentiable curve at a location is the curvature of the circle that best approximates the curve near this point. A straight line has no curvature. In contrast to the tangent, which is a vector quantity, the curvature at a point is normally a scalar quantity, defined by a single real integer.

Circle with center the origin and having radius a

a) r(t) = (acost, asint)

s = [tex]\int\limits^a_b {\sqrt{a^2sin^t+a^2cos^t} } \, dt[/tex]

= at

t = s/a.

b) r(s) = (a cos(s/a), asin(s/a))

= (-a sint, a cost)

r'(t) = a.

c) Graphing the vector include the co-ordinates

T(t) = (-sint, cost)

T(s) = (-sin(s/a), cos(s/a))

Curvature r = [tex]\frac{||T'(t)||}{||r'(t)||}[/tex]

= 1/a.

Therefore, the length of the  curvature is 1/a.
