In response to stated question, we may state that You will need to stitch about 5.0089 metres of piping around the outside border of the area tablecloth, rounded to the closest 0.1 m, for a total length of 5.0 m.
What is area?The size of just an area on either a surface can be represented as an area. The area of an open surface or the border of a two half object is called to as the surface area, meanwhile the area of a horizontal region or planar region pertains to the area of a shape or planar layer. The entire amount of space occupied by a horizontal (2-D) surface or form of an item is referred as its area. With a pencil, draw an square on a sheet of paper. A two-dimensional character. The area of a form on paper is the quantity of area it takes up. Consider the square to be made up of smaller unit squares.
Begin by calculating the radius of the circular tablecloth. We know that the formula A = r2 gives the area of a circle, where A is the area and r is the radius. Hence we may rearrange this formula to find r:
r = √(A/π) = √(2/π) ≈ 0.7979 m (rounded to four decimal places) (rounded to four decimal places)
Now we must determine the circumference of the circle, which is the distance around the tablecloth's outside border. The circumference is calculated using the formula C = 2r.
C = 2π(0.7979) ≈ 5.0089 m
You will need to stitch about 5.0089 metres of piping around the outside border of the tablecloth, rounded to the closest 0.1 m, for a total length of 5.0 m.

You wish to compute the 90% confidence interval for the population proportion. How large a sample should you draw to ensure that the sample proportion does not deviate from the population proportion by more than 0. 08? No prior estimate for the population proportion is available
To compute a 90% confidence interval for the population proportion with a margin of error of 0.08 and no prior estimate for the population proportion, a sample size of 181 is needed.
To determine the sample size needed to compute the 90% confidence interval for the population proportion with a margin of error of 0.08, we can use the formula:
n = (z^2 * p * (1 - p)) / E^2
where n is the sample size needed, z is the z-score for the desired confidence level (90% confidence level has a z-score of 1.645), p is the estimated proportion (since no prior estimate is available, we use 0.5 as a conservative estimate), E is the margin of error (0.08)
Substituting the given values, we get:
n = (1.645^2 * 0.5 * (1 - 0.5)) / 0.08^2
n = 180.99
Rounding up to the nearest whole number, we get:
n = 181
Therefore, a sample size of 181 is needed to compute the 90% confidence interval for the population proportion with a margin of error of 0.08, when no prior estimate for the population proportion is available.

A bag contains 6 red marbles and 1 blue marble. A marble is taken at random, put to one side, and then another marble is taken at random. What is the probability that at least one of the marbles takes was blue?
Give your answer as a fraction in its simplest form
We have 6 red and 1 blue marble thus the probability of drawing blue marble = 1/7
To understand probability as a concept, pay attention to the steps below.
Step 1. Multiply the individual probabilities to obtain the chance of numerous separate events.
Step 2. As there are two separate events in this scenario, double the probabilities of each.
Step 3. Add the individual probabilities to obtain the chance of several events that are mutually exclusive.
In this bag of 7 marbles, there is 1 blue one. Assume that each is marked with a number. Choosing blue-1 has a 1/7 chance of happening. (Why? As there are 7 marbles that may be chosen, each with an equal probability, and since those 7 occurrences are mutually exclusive, the 7 probabilities total up to 1.)
The probability of choosing blue-2 is similarly 1/7; the same goes for blue-3,..., and blue-8. To determine the likelihood of picking a blue, add those up (and blue).
Step 4. Do the same for red next.
Thus the probability of drawing blue marble = 1/7

if a sample of 5 lightbulbs is selected, find the probability that none in the sample are defective.
The probability of selecting a sample of 5 lightbulbs without any defective bulbs is then given by p^5, where p is the probability of not having a defective bulb.
In this situation, the probability of selecting a sample of 5 lightbulbs without any defective bulbs is calculated using the binomial distribution. The probability of success, p, is the probability that a single lightbulb is not defective, and the probability of failure, q, is the probability that a single lightbulb is defective. The probability of selecting 5 lightbulbs with no defective bulbs is then given by the equation:
P(x=0) = (p^5)*(q^0) = p^5
In this case, p is the probability of not having a defective bulb, and q is the probability of having a defective bulb. The probability of selecting 5 lightbulbs without any defective bulbs is then given by p^5.
For example, if the probability of not having a defective bulb is 0.95 and the probability of having a defective bulb is 0.05, then the probability of selecting a sample of 5 lightbulbs without any defective bulbs is 0.95^5 = 0.7737.

The rate of the jetstream is 300 mph traveling with the jetstream an airplane can fly 3000 miles in the same amount of time as it takes to fly 1000 miles against the jetstream. What is the airplanes, average rate in calm air?
The airplane's average rate in calm air is 600 mph.
What is an average?
In mathematics, the average is a measure of the central tendency of a set of numerical values, which is computed by adding all the values in the set and dividing them by the total number of values. The average is also known as the mean, and it is one of the most commonly used measures of central tendency in statistics
Let's denote the airplane's average rate in calm air by x mph.
When the airplane is flying with the jetstream, its ground speed (speed relative to the ground) is x + 300 mph. We know that it can fly 3000 miles in the same amount of time it takes to fly 1000 miles against the jetstream, so we can set up the following equation:
3000 / (x + 300) = 1000 / (x - 300)
We can cross-multiply to simplify:
3000(x - 300) = 1000(x + 300)
Expanding the brackets gives:
3000x - 900000 = 1000x + 300000
Simplifying and rearranging terms gives:
2000x = 1200000
x = 600

In an election, there were three candidates;⅔ of the electors voted for the first candidates,¼ for the second candidate and the rest for the third candidate. If the third candidate got 3290 votes, how many votes did the winner get? Solve this and show All your workings
The winner of the election got 26320 votes.
Let's first find the total number of votes cast in the election. We know that 2/3 fraction of the electors voted for the first candidate and 1/4 of the electors voted for the second candidate. Therefore, the remaining 1/12 of the electors voted for the third candidate. So, we have:
2/3 + 1/4 + 1/12 = 8/12 + 3/12 + 1/12 = 12/12 = 1
This means that all the electors voted, and the total number of votes cast is equal to the total number of electors.
Now, let's find the number of votes the third candidate got, which is 1/12 of the total number of votes. We know that this is equal to 3290. So, we have
1/12 x Total Number of Votes = 3290
Multiplying both sides by 12, we get:
Total Number of Votes = 3290 x 12 = 39480
Now, we can find the number of votes the first candidate got, which is 2/3 of the total number of votes. We have:
2/3 x Total Number of Votes = 2/3 x 39480 = 26320 votes

what happens to the sector area of a circle if you double its radius? what happens to the arc length of a circle if you double its radius? why do you think that happens?
The sector area of a circle is quadrupled when the radius is doubled. When the radius is doubled, the arc length of a circle is also doubled. This happens because the sector area and arc length are both dependent on the radius of a circle. Therefore, any change in the radius of a circle affects both its sector area and arc length.
Let us understand both these concepts in detail:
Sector area of a circle: A sector is a region of a circle, and the area enclosed by two radii and an arc is known as a sector area. The formula for the sector area of a circle is given by:
Sector Area = (θ/360)πr²
where θ is the central angle in degrees,
r is the radius of the circle,
and is a constant value.
If we double the radius of a circle, the sector area increases by a factor of 4. This is because the sector area is directly proportional to the square of the radius.
Hence, doubling the radius of a circle results in an increase in the sector area by a factor of 22 (four).
Arc length of a circle: The length of an arc is the distance between two points on a circle. The formula for the arc length of a circle is given:
Arc Length = (θ/360)2πr
where θ is the central angle in degrees,
r is the radius of the circle,
and 2pie is a constant value.
If we double the radius of a circle, the arc length also doubles.
This is because the arc length is directly proportional to the radius.
Hence, doubling the radius of a circle results in an increase in the arc length by a factor of 2.

Roland's family drove 4 6/10 kilometers from their home to the gas station. They drove 2 30/100 kilometers from the gas station to the store. Which expression can be used to determine the number of kilometer Ronald's family drove altogether
The following phrase can be used to calculate the total amount of kilometre that Roland's family travelled: 2 30/100 plus 4 6/10 equals 69/10 kilometres.
The distance from house to the gas station and the distance from the gas station to the store must be added in order to calculate the total number of kilometre driven by Roland's family.
The distance between their house and the petrol station is 4 6/10 kilometres, which can also be expressed using an incorrect fraction as follows:
4 6/10 = (4 × 10 + 6) / 10 = 46/10
The distance between the petrol station and the store can be expressed as 2 30/100 kilometres, which can be written as follows:
2 30/100 = (2 × 100 + 30) / 100 = 230/100
We sum the two distances to get the total distance travelled:
46/10 + 230/100
We must identify a common denominator in order to add these fractions. Both 10 and 100 can be divided into only one single digit, which is 100. Hence, using 100 as the common denominator, we can rewrite the expression as follows:
(46/10) * (10/10) + (230/100) * (1/1)
That amounts to:
460/100 + 230/100 = 690/100
So, by dividing the numerator and denominator by their 10 greatest common factor, we may reduce this fraction:
690/100 = (690 ÷ 10) / (100 ÷ 10) = 69/10

in a simple linear regression analysis, if the coefficient of correlation is -0.933, then the percentage of the total sum of squares that can be explained by using the estimated regression equation is
In a simple linear regression analysis, the coefficient of correlation (also known as the Pearson correlation coefficient) measures the strength and direction of the linear relationship between the dependent variable and the independent variable.
A value of -0.933 indicates a strong negative correlation, meaning that as one variable increases, the other variable tends to decrease.
To determine the percentage of the total sum of squares that can be explained by using the estimated regression equation, we need to look at the coefficient of determination (R-squared). R-squared is the proportion of the variance in the dependent variable that is explained by the independent variable(s).
The square of the coefficient of correlation (r) gives us the R-squared value. Therefore, in this case, the R-squared value would be:
R-squared = (-0.933)^2 = 0.871
This means that 87.1% of the total sum of squares can be explained by using the estimated regression equation. The remaining 12.9% of the variation in the dependent variable is unexplained and is attributed to other factors that are not included in the model.

If the teacher wants to retire with at least $125,000 in the account, how much money must be initially invested? Round your answer to the nearest dollar.
Therefore, the teacher must initially invest at least $7,725 to retire with at least $125,000 in the account after 40 years at a 6.95% annual interest rate compounded continuously.
What is percent?Percent is a way of expressing a number as a fraction of 100. It is often denoted by the symbol "%". Percentages are commonly used to describe proportions or rates, such as the percentage of students who passed a test, the percentage of a population that belongs to a certain group, or the percentage increase or decrease in a quantity over time. Percentages are also used in calculations involving discounts, taxes, interest rates, and other financial applications.
Here,
The formula for the continuous compounding interest is given by:
[tex]A = Pe^{rt}[/tex]
where A is the final amount, P is the principal amount (initial investment), e is the constant 2.71828..., r is the annual interest rate as a decimal, and t is the time in years.
In this case, we want to solve for the initial investment P, given that the teacher wants to retire with at least $125,000 in the account after 40 years, and the annual interest rate is 6.95% compounded continuously. Therefore, we have:
A = $125,000
r = 0.0695 (annual interest rate as a decimal)
t = 40 years
Substituting these values into the formula, we get:
$125,000 = [tex]Pe^{0.0695*40}[/tex]
Dividing both sides by [tex]e^{0.0695*40}[/tex], we get:
P = $125,000 / [tex]e^{0.0695*40}[/tex]
Using a calculator, we find that [tex]e^{0.0695*40}[/tex] is approximately 16.173, so:
P = $125,000 / 16.173
P ≈ $7,725.32

3. if you measure an interval of 5 seconds between seeing a lighting flash and hearing the thunder, how far away was the lighting? assume the temperature of the air was 20 degree celsius.
It took 5 seconds for the thunder to be heard, the lightning was 343 * 5 = 1715 meters away.
The distance between the lightning flash and hearing the thunder can be calculated using the speed of sound. The speed of sound in air at 20°C is 343 meters/second.
Explanation: When lightning strikes, the initial flash travels at the speed of light, which is 299,792,458 meters per second. The sound wave created by the flash, however, travels at a much slower speed.
The speed of sound in air at 20°C is 343 meters per second.
To calculate the distance of the lightning, we multiply the speed of sound by the amount of time it took to hear the thunder. In this case, the amount of time was 5 seconds, so the lightning was 1715 meters away (343 * 5 = 1715).

Perform the indicated operation.
f(x) = −3x² + 3x; _g(x) = 2x+5
(ƒ + g)(3)
The composite function (f + g)(3) when evaluated from f(x) = −3x² + 3x and g(x) = 2x+5 is -7
Calculating the composite functionGiven that
f(x) = −3x² + 3x and
g(x) = 2x+5
To perform the operation (ƒ + g)(3), we need to add the functions ƒ(x) and g(x) first, and then evaluate the sum at x = 3.
ƒ(x) = −3x² + 3x
g(x) = 2x + 5
To add the functions, we simply add their corresponding terms:
(ƒ + g)(x) = ƒ(x) + g(x) = (−3x² + 3x) + (2x + 5)
When the like terms are evaluated, we have
(ƒ + g)(3) = −3x² + 5x + 5
Now, we can evaluate the sum at x = 3:
(ƒ + g)(3) = −3(3)² + 5(3) + 5
So, we have
(ƒ + g)(3) = −27 + 15 + 5
Lastly, we have
(ƒ + g)(3) = -7
Therefore, (ƒ + g)(3) = -7.
