Answer:

10,200 Dollars

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year.

Solving our equation:

A = 7500(1 + (0.06 × 6)) = 10200  

A = $10,200.00

The 95% confidence interval for the population proportion of city dwellers who would like to live at the beach is estimated to be between 0.56 and 0.62.

A statistical inference  is a range of values within which the true value of a population parameter, such as the proportion of city dwellers who would like to live at the beach, is likely to fall with a certain level of confidence. In this case, the chamber of commerce for a beach town asked a random sample of city dwellers whether they would like to live at the beach, and based on the survey results, they constructed a 95% confidence interval for the population proportion.

The 95% confidence interval they obtained was (0.56, 0.62). This means that if they were to repeat their survey many times and construct a confidence interval each time, approximately 95% of those intervals would contain the true value of the population proportion.

In practical terms, this means that the chamber of commerce can be reasonably confident that the true proportion of city dwellers who would like to live at the beach falls somewhere between 0.56 and 0.62. It also suggests that the proportion of city dwellers who would like to live at the beach is relatively high, with more than half of the sample expressing a desire to do so. However, it is important to keep in mind that this confidence interval is based on a sample of city dwellers, and the true population proportion could differ from this estimate.

Step-by-step explanation:

The answer is (i) and (ii). In the first graph, as x approaches very large values such as infinity, the y-value will also approach infinity. In the second graph, as x approaches infinity, the y-value again approaches infinity.

On the contrary, the third graph approaches large negative values as x increases. It approaches negative infinity.

The functions have the same end behavior as x increases will be Graph first and second , so the correct option is D

The end behavior of a function refers to the behavior of the function as x approaches positive or negative infinity.

To determine which functions have the same end behavior as x increases, we need to analyze the behavior of each function as x approaches positive infinity.

we can see that the first graph, as x approaches very large values such as infinity, the y-value will also approach infinity.

Also the second graph shows that as x approaches infinity, the y-value again approaches infinity.

Then the third graph approaches large negative values as x increases. It approaches negative infinity.

False. It is not optimal for Anil to give Bala one-third of the lottery money (£33.33). According to Anil's preferences, his utility function is given by u(A,B) = min{2A, B}.

This function implies that Anil values his own money (A) more than the money he gives to Bala (B). By giving Bala one-third of the money, Anil would keep only £66.67 for himself, which is less than what he could potentially keep if he gave Bala a smaller amount. To maximize his own utility, Anil should give Bala the minimum amount possible, which in this case would be zero.

Anil's utility function indicates that he values his own money (A) twice as much as the money he gives to Bala (B). By maximizing his utility, Anil would want to keep as much money for himself as possible, while still giving Bala some amount of money. In this case, Anil can keep £100 for himself, which is the maximum amount possible, while giving Bala £0.

This division of money maximizes Anil's utility according to his preferences. Therefore, it is not optimal for Anil to give Bala one-third of the lottery money; instead, he should give Bala the minimum amount of £0 to maximize his own utility.

The price at which the total quantity supplied is 250 is $11.58.

In order to find the price at which the total quantity supplied is 250, we need to equate the total quantity supplied by both producers (Supply 1 and Supply 2) and solve for the price.

Supply 1: P = 6 + 0.7Q

Supply 2: P = 16 + 0.6Q

To find the equilibrium price, we set the total quantity supplied equal to 250:

0.7Q + 0.6Q = 250

1.3Q = 250

Q = 250 / 1.3 ≈ 192.31

Now that we have the quantity, we can substitute it back into either supply function to find the price. Let's use Supply 1:

P = 6 + 0.7Q

P = 6 + 0.7 * 192.31

P ≈ 6 + 134.62

P ≈ 140.62

Therefore, the price at which the total quantity supplied is 250 is approximately $11.58.

Answer:

The volume of the composite figure is 162.7 in^3

Step-by-step explanation:

Here, we have a cylinder placed over a cube

The volume of the cube is L^3

With L being the length of its side = 5

The volume of the cube is 5^3 = 125 in^3

The volume of the cylinder is pi * r^2 * h

with r = 2 in and h = 3 in

The volume of the cylinder = 22/7 * 2^2 * 3 = 37.699 = 37.7 in*3

Total volume is thus;

37.7 + 125 = 162.7 in^3

The total income of the entire population is rising at a rate of $18.16 billion per year in 1997.

In this problem, we are given the population of a country and its annual growth rate, as well as the average annual income of a person and its growth rate. We need to determine how quickly the total income of the entire population is rising in 1997.

First, let's calculate the total population growth in 1997:

Population in 1997 = 20 million

Population growth rate = 0.2 million per year

So, the population in 1998 will be:

Population in 1998 = 20 million + 0.2 million = 20.2 million

Now, let's calculate the average income growth in 1997:

Average income in 1997 = $15,000 per year

Income growth rate = $800 per year

So, the average income in 1998 will be:

Average income in 1998 = $15,000 + $800 = $15,800 per year

Next, we need to calculate the total income of the entire population in 1997:

Total income in 1997 = Population in 1997 x Average income in 1997

Total income in 1997 = 20 million x $15,000 = $300 billion per year

Now, let's calculate the total income of the entire population in 1998:

Total income in 1998 = Population in 1998 x Average income in 1998

Total income in 1998 = 20.2 million x $15,800 = $318.16 billion per year

Finally, we can determine how quickly the total income of the entire population is rising in 1997:

Total income growth rate = (Total income in 1998 - Total income in 1997) / 1 year

Total income growth rate = ($318.16 billion - $300 billion) / 1 year

Total income growth rate = $18.16 billion per year

The real number line is an infinitely long line that consists of all the rational and irrational numbers. Since the irrational numbers cannot be expressed as a ratio of two integers, they cannot be represented as terminating or repeating decimals.

Therefore, finding the location of an irrational number on the real number line requires using a system of equations that can only be solved by approximation.

One such system of equations is the decimal expansion of the irrational number.

For example, the square root of 2 is an irrational number that can be approximated by the decimal expansion 1.41421356...

To find the location of the square root of 2 on the real number line, we can use the equation x^2=2 and solve for x using iterative methods such as the Newton-Raphson method.

Another method to find the location of an irrational number on the real number line is to use the concept of limits. We can define a sequence of rational numbers that approach the irrational number, and use the limit of the sequence to approximate the location of the irrational number on the real number line.

In summary, finding the location of an irrational number on the real number line requires using approximation methods such as decimal expansion, iterative methods, or limits.

7) α and β are first-quadrant angles, sin α = 5/13, and cos β = 3/5, then sin(α - β) = -33/65

9) α and β are first-quadrant angles, sin α = 5/13, and cos β = 3/5, then cos(α - β) = 56/65

sin θ = -5/13, and tan Φ = -8/15

Where θ is in the third quadrant, and Φ is in the second quadrant

Now, sin(θ + Φ) is expressed as; sin θ cos Φ + sin Φ cos θ

Since θ is in the third quadrant, then cos θ = -12/13

Φ is in the second quadrant and as such sin Φ = 8/17 and cos Φ = -15/17

cos (α - β) = cos α cos β + sin α sin β

= (12/13 * 3/5) + (5/13 * 4/5)

= 36/65 + 20/65

= 56/65
