5 miles is the distance a cyclist travels in 20 minutes, then 0.25 miles does the cyclist travel in 1 minutes.

A mile was equivalent to 1,000 Roman strides, with a stride being equal to two paces. The term "mile" is derived from the Latin "mille passus," which means "one thousand paces." The English Parliament established the Mile at eight furlongs (one furlong is 660 feet) in 1592. 5,280 feet, 1,760 yards, or around 1,609 meters make up a mile. On July 1, 1959, an international agreement established the mile's precise measurement at 1609.344 metres. Currently, the mile is the only unit of measurement used in the US and UK.

So, a mile is one of many different distance units.

Given that,

In 20 minutes a cyclist travels distance of 5 miles

So, in 1 minutes cyclist travels distance of [(5/20) × 1] miles

(a) A sample size of 784.44 is required to estimate the population proportion to within an error of 0.03 with 95% confidence.

(b) A sample size of 393.22 would be required if no information from a pilot study is available.

What is a sample size?

Sample size refers to the number of observations or measurements that are taken from a larger population as part of a statistical study. In statistical analysis, a sample is a subset of the population being studied, and the sample size is the number of observations or units of analysis included in the sample.

To answer this question, we need to use the formula for the sample size of a proportion:

[tex]n = \frac{Z^2 * p * (1 - p))}{e^2}[/tex]

Where n is the sample size, Z is the z-score corresponding to the desired confidence level (in this case, Z = 1.96 for a 95% confidence level), p is the estimated population proportion (in this case, p = 0.75 based on the information provided in the question), and e is the desired margin of error (in this case, e = 0.03).

Plugging these values into the formula, we get:

[tex]n = \frac{(1.96^2 * 0.75 * 0.25)}{0.03^2} \\\\n= 784.44[/tex]

If no information from a pilot study is available, we would need to use a default value for p (such as p = 0.5) in the formula. In this case, we would get:

[tex]n = \frac{(1.96^2 * 0.5 * 0.5)}{0.03^2}\\\\n= 393.22[/tex]

Hence,

(a) A sample size of 784.44 is required to estimate the population proportion to within an error of 0.03 with 95% confidence.

(b) A sample size of 393.22 would be required if no information from a pilot study is available.

The Population Changes table indicate the following percent of change of the three towns

Question 1: The percent of change for Centerville is about 29.6%

Question 2: The town with the greatest percent of change is Riverview

Question 3: The percent of change for Riverview is about 51%

A percent of change is the change in the value of a parameter, expressed as a percentage.

Question 1: The population Centerville in 2000 = 37,065

The population of Centerville in 2010 = 26,102

The percentage change can be found using the formula;

[tex]Percentage \ change=\dfrac{New \ value - Initial \ value}{Initial\ value} \times 100[/tex]

The percentage change for Centerville is therefore;

[tex]Percentage \ change=\dfrac{Population \ in \ 2010-Polulation \ in \ 2000}{Population \ in \ 2000} \times 100[/tex]

From which we get;

[tex]Percentage \ change \ for \ Centerville=\dfrac{26102-37065}{37065} \times 100 \approx -29.6\%[/tex]

Question 2:

The percent of change for the town of Lakeside is found as follows;

Percentage change = ((45,863 - 51,342)/(51,342)) × 100 ≈ -10.7%

The percent of change of the population of Riverview is found using the percentage change formula as follows;

Percentage change = ((63017 - 41726)/(41726)) × 100 = 51%

Therefore, the town that had the greatest percent of change is is Riverview

Answer:

To solve this problem, we first need to find out how much time it will take for the airplane that is descending to reach the same altitude as the airplane that is ascending. To do this, we can use the formula d = r * t, where d is the distance, r is the rate, and t is the time.

In this case, the distance is the difference between the starting altitudes of the two airplanes, which is 42,000 feet for the descending airplane and 0 feet for the ascending airplane. The rate is the rate at which the descending airplane is descending, which is 3,500 feet per minute. Plugging these values into the formula, we get:

d = r * t

d = (3,500 feet/minute) * t

d = 42,000 feet

Solving for t, we get:

t = d / r

t = (42,000 feet) / (3,500 feet/minute)

t = 12 minutes

So it will take 12 minutes for the descending airplane to reach the same altitude as the ascending airplane.

To find the altitude at which the two airplanes will be at the same altitude, we can use the formula d = r * t, where d is the distance, r is the rate, and t is the time. In this case, the distance is the altitude at which the two airplanes will be at the same altitude, the rate is the rate at which the ascending airplane is ascending, which is 2,500 feet per minute, and the time is the time it will take for the descending airplane to reach the same altitude as the ascending airplane, which we calculated to be 12 minutes.

Plugging these values into the formula, we get:

d = r * t

d = (2,500 feet/minute) * (12 minutes)

d = 30,000 feet

Therefore, the altitude at which the two airplanes will be at the same altitude is 30,000 feet.

There are several other ways we could have solved this problem. For example, we could have used the formula d = r * t to find the altitude of the ascending airplane at the same time that the descending airplane reaches the same altitude, and then subtracted the starting altitude of the ascending airplane (0 feet) from this value to find the altitude at which the two airplanes will be at the same altitude.

Another way to solve this problem is to use the formula d = (v1 + v2) * t / 2, where d is the distance, v1 and v2 are the rates at which the two airplanes are moving, and t is the time. In this case, we can set d equal to the difference between the starting altitudes of the two airplanes, v1 equal to the rate at which the descending airplane is descending, v2 equal to the rate at which the ascending airplane is ascending, and t equal to the time it will take for the descending airplane to reach the same altitude as the ascending airplane.

Plugging these values into the formula, we get:

d = (v1 + v2) * t / 2

d = (3,500 feet/minute + 2,500 feet/minute) * (12 minutes) / 2

d = (6,000 feet/minute) * (12 minutes) / 2

d = (72,000 feet) / 2

d = 36,000 feet

Therefore, the altitude at which the two airplanes will be at the same altitude is 36,000 feet.

We can also solve this problem using a table to track the altitude of the two airplanes over time. We can start by making a table with

The amount that Alan can be able to borrow for credit balance is $8,500.

What is credit balance?

The capacity to access products or services or borrow money with the idea that you'll pay for them later is known as credit. An amount that the card issuer owes you can be seen as a credit balance on your billing statement. With each payment you make, credits are added to your account. When you return something you purchased with a credit card, a credit might be added.

Given, total limit =  $10,000

Borrowed amount = $2,000

paid back = $500

So, remaining amount that he can borrow = $10,000 - $2,000 + $500

Remainder Theorem is an approach of Euclidean division of polynomials. According to this theorem, if we divide a polynomial P(x) by a factor ( x – a); that isn’t essentially an element of the polynomial; you will find a smaller polynomial along with a remainder. This remainder that has been obtained is actually a value of P(x) at x = a, specifically P(a)

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the angle be represented as θ

Now , given that the angle θ is acute

Acute angles measure less than 90 degrees

So , the value of θ < 90°

when the value of sec θ = 2

cos θ = 1/sec θ

So , cos θ = 1/2

The value of θ when cos θ is 1/2 is when the angle θ is 60°
