The measure of lengths of the right triangle is solved by trigonometric relations and

a) A = 32°

b) b = 22.4 units

c) c = 26.4 units

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of sides of the triangle are

The measure of ∠A = 180° - ( 90° + 58° )

The measure of ∠A = 32°

From the trigonometric relation , we get

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

So , tan 58° = b / 14

Multiply by 14 on both sides , we get

b = 22.4 units

Now , sin 58° = 22.4 / c

Multiply by c on both sides , we get

c = 22.4 / sin 58°

c = 26.4 units

Hence , the triangle is solved

Where f(x) is the probability density function of X. In both cases, the expected value represents the average outcome or value that can be expected over many trials or observations.

The formula for the expected value or mean probability is a long answer that depends on the specific situation or probability distribution being analyzed.

In general, the expected value is calculated by multiplying each possible outcome by its corresponding probability and then summing these products together.

For discrete probability distributions, this formula can be written as:
E(X) = Σ(x * P(X=x))

Where X is the random variable, x is a possible outcome, and P(X=x) is the probability of X taking on the value x.

For continuous probability distributions, the formula is similar, but involves integration instead of summation:
E(X) = ∫(x * f(x)) dx

Where f(x) is the probability density function of X. In both cases, the expected value represents the average outcome or value that can be expected over many trials or observations.

Answer:

The answer is C or the third one

Step-by-step explanation:

The smaller sample's margin of error will be almost twice as great as the larger sample's margin of error.

Calculating the margin of error for a given sample from a population:

Let the level of significance be   and the standard deviation of the population be σ and the sample size be n, then we have:

MOE(Margin of Error)=  \(z_{a/2}\times\frac{\sigma}{\sqrt n}\)

Using the above formula to calculate the margin of errors for two specified samples

For first sample:

Sample size = n(1) = 1000

MOE(1) = \(z_{a/2}\times\frac{\sigma}{\sqrt {1000}}\)

For second sample:

Sample size = n(2) = 4000

MOE(2) = \(z_{a/2}\times\frac{\sigma}{\sqrt {4000}}\)

(since it was given that they have same point estimates, so same standard deviation)

Their ratios are given by

MOE(2)/MOE(1) = \(\frac{z_{a/2}\times\frac{\sigma}{\sqrt {4000}}}{z_{a/2}\times\frac{\sigma}{\sqrt {1000}}}\)

MOE(2)/MOE(1) = \(\sqrt{\frac{1000}{4000}}\)

MOE(2)/MOE(1) = 1/2

MOE(1) = 2*MOE(2)

Thus, the margin of error from the smaller sample will be about double of the margin of error from the larger sample.

The equation of the normal line to the parabola y = x² - 7x + 4 that is parallel to the line x - 3y = 2 is y = (1/3)x - 85/9.

The equation of the normal line to the parabola y = x^2 - 7x + 4 that is parallel to the line x - 3y = 2, we need to determine two things:

The slope of the normal line and the point of tangency between the parabola and the normal line.

The given line x - 3y = 2 can be rewritten in slope-intercept form as y = (1/3)x - 2/3.

Since the normal line is parallel to this line, it will have the same slope.

The slope of the normal line is the negative reciprocal of the slope of the tangent line to the parabola at the point of tangency.

To find the point of tangency, we need to find the x-coordinate where the derivative of the parabola is equal to the slope of the given line.

The derivative of the parabola y = x² - 7x + 4 is obtained by differentiating each term separately:

dy/dx = 2x - 7

Setting this derivative equal to the slope of the given line (1/3), we have:

2x - 7 = 1/3

Simplifying, we get:

2x = 7 + 1/3

2x = 22/3

x = 11/3

Now, we can find the corresponding y-coordinate by substituting this value of x into the original equation of the parabola:

y = (11/3)² - 7(11/3) + 4

y = 121/9 - 77/3 + 4

y = 121/9 - 231/9 + 36/9

y = -74/9

The point of tangency is (11/3, -74/9).

Now that we have the slope of the normal line (1/3) and the point of tangency (11/3, -74/9), we can use the point-slope form of a line to find the equation of the normal line:

y - (-74/9) = (1/3)(x - 11/3)

Simplifying further, we get:

y + 74/9 = (1/3)x - 11/9

Rearranging the terms, we have:

y = (1/3)x - 11/9 - 74/9

y = (1/3)x - 85/9

Step-by-step explanation:

The proportion of weeks in which the waste disposal facility in KnowWearSpatial, U.S.A. is overloaded is approximately 0.4904 or 49.04%.

To find the proportion of weeks in which the facility is overloaded, we need to calculate the probability of the waste weights being greater than 27.09 lb. This can be done by calculating the z-score and then looking up the corresponding probability from the standard normal distribution table or using a calculator.

Here are the steps to calculate the proportion:

⇒ Calculate the z-score

The z-score can be calculated using the formula:

z = (x - μ) / σ

where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

In this case, we want to find the z-score for x = 27.09 lb.

z = (27.09 - 26.79) / 12.03

⇒ Look up the probability

Using the z-score obtained in Step 1, we can find the corresponding probability from the standard normal distribution table or using a calculator.

⇒ Calculate the proportion

The proportion of weeks in which the facility is overloaded is equal to 1 minus the probability calculated in Step 2.

Now, let's perform the calculations:

→ Calculate the z-score

z = (27.09 - 26.79) / 12.03

z ≈ 0.0249

→ Look up the probability

Using the z-score 0.0249, we can find the corresponding probability from the standard normal distribution table or using a calculator. The probability is approximately 0.5096.

→ Calculate the proportion

The proportion of weeks in which the facility is overloaded is 1 - 0.5096 = 0.4904.

Therefore, the proportion of weeks in which the waste disposal facility is overloaded is approximately 0.4904 or 49.04%.

A linear system with 3 equations and 4 variables by representing it with an augmented matrix and bringing the matrix to reduced row-echelon form can be solved.

A mathematical representation of a system based on the application of a linear operator is known as a "linear system" in systems theory. Ordinarily, compared to nonlinear systems, linear systems display much simpler features and properties. The automatic control theory, signal processing, and telecommunications all heavily rely on linear systems as a mathematical abstraction or idealisation.

Linear systems, for instance, are frequently used to model the propagation medium for wireless communication systems. An operator, H, that converts an input, x(t), into an output, y(t), a kind of black box description, can be used to describe a general deterministic system.

The superposition principle, or alternatively both the additivity and homogeneity properties, must be satisfied by a system to be considered linear, and only then.

Most people, if not all in the US always want to live the American dream at some point in their lives. But the question is, what is the meaning of the American dream, and how can people achieve this vague and elusive realisation? The American dream is a national philosophy or a belief that specifies the ideal factors such as democracy, freedom, rights and equality that accords every citizen equal opportunity to prosper and achieve their set goals (Glenn, 2002). The foundation of the American dream is deeply rooted in the declaration of independence that assert that “all men are created equal”. In simple terms, the American dream eliminates the artificial barriers to prosperity and promotes upward social mobility for every individual in the US depending on their hard work irrespective of their, social, religious, historical and racial background. The American dream is a slogan that is selling across the globe and up to date we see millions of people crossing the American borders as immigrants in search of this dream that cannot otherwise be achieved in their homelands. The American dream is a reality as we see it through how different people in the US have developed and better their own ingenuity and achieve their goals through their best efforts. Making this dream a reality is not a straight path as it is all about overcoming the challenges which at the end of the day differentiates a resilient individual from the rest.

The student covers a total distance of 22.05 kilometers in a week's time, walking between the park and the house each day.

To find the total distance covered by the student in a week's time, we need to calculate the distance covered in one round trip (from the house to the park and back) and then multiply it by the number of round trips in a week.

Given that the difference between the park and house is 1 kilometer and 575 meters, we can convert it to a total distance of 1.575 kilometers.

In a round trip, the student covers twice the distance between the park and the house, which is 1.575 kilometers * 2 = 3.15 kilometers.

Now, we need to determine how many round trips the student makes in a week. Let's assume the student makes one round trip each day.

Since there are 7 days in a week, the total distance covered by the student in a week's time is 3.15 kilometers * 7 = 22.05 kilometers.

The population at the end of the 5th year with a decline of 3% each year will be 2147.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

As per the given,

The bird population is declining at a rate of 3% a year.

Suppose the initial population = P

After the end of 1st year = 3% less than P = P - 0.03P = 0.97P

After the end of 2nd year = 3% less than after the end of 1st year

⇒  0.97P - 0.03 x 0.97P = 0.9409P

After the end of 3rd year = 3% less than after the end of 2nd year

⇒  0.9409P - 0.03 x 0.9409P = 0.912673P

After the end of 4th year = 3% less than after the end of 3rd year

⇒  0.912673P - 0.03 x 0.912673P = 0.88529281P

After the end of the 5th year = 3% less than after the end of 4th year

To know how much lemonade you can buy with $320, we first need to determine the price of a pint of ice cream. Since you can buy 80 pints with $320, the price of one pint of ice cream is $320 divided by 80, which equals $4.

Next, we need to find the price of a glass of lemonade, which is 3.2 times less than the price of ice cream. Therefore, the price of a glass of lemonade is $4 - (3.2 * $4) = $4 - $12.8 = -$8.8.

Since the price of lemonade is negative, it indicates that you will receive money back for every glass of lemonade you buy. However, since you cannot have a negative quantity of lemonade, the answer would be zero.

In summary, with $320, you can buy zero glasses of lemonade.
