The function f(x) is translated 3 units right and 5 units down then the function f(x) is coincident with the function g(x).

A function is an assertion, conception, or regulation that establishes a partnership between two variables.

The functions f(x) and g(x) are given below.

f(x) = 1 / x

g(x) = 1 / (x - 3) - 5

Translate the function 3 units right, then replace x with (x - 3). And translate the function 5 units down, then replace f(x) with (g(x) + 5). Then we have

g(x) + 5 = 1 / (x - 3)

For the given table -

The equation for line of best fit is Y = -1.000 · X + 11.25.

The correlation coefficient is -0.443533.

x and y have negative and strong correlation.

What is correlation coefficient?

A statistical concept known as the correlation coefficient aids in establishing a relationship between expected and actual values gained through statistical experimentation. The estimated correlation coefficient's value explains how well the expected and actual values match.

The table of data is given.

The formula for equation of the line of best fit is -

Y = b·X + a

On adding the values in a graphing calculator the equation is -

Y = -1.000 · X + 11.25

Here, the slope is -1 and y-intercept is 11.25.

The formula for correlation coefficient is -

r = [n(∑xy) - (∑x)(∑y)] / [n∑x² - (∑x²)][n∑y² - (∑y²)]

n = Number of values or elements

∑x = Sum of 1st values list

∑y = Sum of 2nd values list

∑xy = Sum of the product of 1st and 2nd values

∑x² = Sum of squares of 1st values

∑y² = Sum of squares of 2nd values

For the given table the values are -

n = 8, ∑x = 68, ∑y = 22, ∑xy = 145, ∑x² = 620, ∑y² = 274

Plug in all the values in the equation -

r = [8(145) - (68)(22)] / [8(620) - (620)][8(274) - (274)]

r = -0.443533

When the values of two variables grow while one variable's values fall. The correlation coefficient would be negative in that situation.

The weak and adverse association is indicated by the coefficient's negative value. And if "r" keeps moving in the direction of -1, the relationship is moving in the negative direction.

Therefore, the equation is Y = -1.000 · X + 11.25 and r value is -0.443533.

The primary difference between writing the name of a segment and the name of a line is the use of symbols.

A symbol is an object, image, or action that stands for or represents something else. Symbols can be used to convey a wide variety of ideas and concepts, from the literal, such as a heart to represent love, to the abstract, such as a peace sign to represent a call for world peace. Symbols are often used to communicate complex ideas quickly and easily.

To denote a segment, a line is usually written with two arrows pointing in opposite directions, such as ↔. To denote a line, the line is usually written with a single arrow pointing in one direction, such as →.

For example, if you were writing the name of a segment called "AB", then you would use the symbol ↔ AB. If you were writing the name of a line called "AB", then you would use the symbol → AB.

(a)

given m varies directly as n then the equation relating them is

m = kn ← k is the constant of variation

to find k use the condition m = 14 when n = 7

14 = 7k ( divide both sides by 7 )

2 = k

m = 2n ← equation of variation

In a case whereby the  total mass of a box and some oranges was 25 kg. The total mass of the same box and some apples was 11 kg. The mass of the oranges was 3 times the mass of the apples, the mass of the oranges is 21kg.

The concept that will be used here is simplificatiopn.

We can set up as:

let a represent the box

let b represent the orange

lect c represent the apple

Then a + b = 25

a+ c = 11 ....................................................(2)

b = 3c.......................................(3)

substract equation 2 from 1

b-c = 11 ....................................(4)

A manufacturer working at the 430 gram setting, and a 21 bag sample had a mean of 421 grams with a standard deviation of 15. The p-value of test statistic is 0.0074.

To test whether the bag filling machine works correctly at the 430 gram setting, we can conduct a one-sample t-test. The null hypothesis is that the true mean weight of the bags filled by the machine is equal to 430 grams, and the alternative hypothesis is that the true mean weight is less than 430 grams.

The test statistic is calculated as:

t = (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size))

Plugging in the values given in the problem, we get:

t = (421 - 430) / (15 / sqrt(21)) = -2.77

The degrees of freedom for the t-distribution are n - 1 = 20.

Using a t-table or calculator, we can find the p-value associated with a t-score of -2.77 and 20 degrees of freedom. The p-value turns out to be 0.0074 (rounded to four decimal places).

Since the p-value is less than the level of significance of 0.1, we can reject the null hypothesis and conclude that the bag filling machine is underfilling the bags at the 430 gram setting.

From the following, a panel data set consists of data on the same cross-sectional units over a given period of time while a pooled data set consists of data on different cross-sectional units over a given period of time is the difference between panel and pooled cross-sectional data.

Panel data refers to samples of the same cross-sectional units observed at multiple points in time.

For example we will follow the same set of households X, Y and Z, for each time period we collect data i.e. in 1990 and we will also interview the same households in 1995.

Pooled data occur when we have a “time series of cross sections,” but the observations in each cross section do not necessarily refer to the same unit.

For example we will take household income data on households X, Y and Z, in 1990. And then we will take the same income data on households G, F and A in 1995. Although we are interested in the same data, we are taking different samples (using different households) in different time periods.

The probability of the sample mean annual insurance cost being greater than $620 is very low, that is 0.00317% which indicating that it is unlikely to happen by chance.

Probability is a branch of mathematics that deals with the likelihood of an event happening. It is used in various fields, such as insurance, finance, and science.

To calculate the probability, we need to use the central limit theorem, which states that the distribution of sample means of a population approaches a normal distribution as the sample size increases. We also need to know the mean and standard deviation of the population.

Assuming that the population is normally distributed, we can use the following formula to calculate the probability:

z = (x - μ) / (σ / √(n))

where z is the z-score, x is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.

In this case, we don't know the population mean and standard deviation, but we can use the sample mean and standard deviation as estimates. Let's say we have a sample of 100 insurance costs with a mean of $600 and a standard deviation of $50.

Now, we can calculate the z-score:

z = (620 - 600) / (50 / √(100)) = 4

The z-score of 4 indicates that the sample mean of $620 is 4 standard deviations away from the mean of $600. We can use a standard normal distribution table or a calculator to find the probability of getting a z-score of 4 or higher. The probability is very small, approximately 0.0000317 or 0.00317%.

The profit made on the transaction by the dealer was Rs. 7,750.

To calculate the profit made by the second hand car dealer, you can subtract the cost of buying the car and the transaction costs from the selling price.

Profit = Selling Price - Cost of Car - Transaction Costs

Profit = 93,000 - 85,000 - 250

Profit = 7,750

So the dealer made a profit of Rs. 7,750 on the transaction.

The cost to ship a box of 250 grams, with 10 books of weight of 8.5kg by natalie is $ 29.75.

The total weight of the books and the box is:

To convert this to kilograms, we divide by 1000:

8,500 grams ÷ 1000 = 8.5 kg

The cost of shipping will be based on the weight, so we can multiply the weight in kilograms by the shipping cost per kilogram:
