Given that,

We have to find how many different ways can the 26 different letters be arranged so that either the word "the" or the word "aid" are present.

We know that,

Total number of arrangements of 26 different letters= 26!

Let A be the number of arrangements that contains 'the' = 24! ( Total no. Of alphabet= 26 subtract the number That contains 'the' i.e, 3 and add one for 'the' 26-23+1=24)

Let B be the number of arrangements that contains 'aid' = 24! (Total no. Of alphabet minus number of letter in 'aid' and add 'aid' as an alphabet i.e, 26-23+1= 24)

Total no. Of arrangements that contains either sequence 'the' or 'aid'

A or B= (A)+(B)- (A intersection B)

24! +24! -22! = 1.239x10²⁴

Therefore, 1.239x10²⁴ different ways can the 26 different letters be arranged so that either the word "the" or the word "aid" are present.

P(4, 7.25) are the coordinates of circumcentre of the triangle

The circumcenter of a triangle is the point where the perpendicular bisectors of the sides of that particular triangle intersect

Given: The vertices R(-2,5), S(-6, 5), T(-2,-1)​

Let P(x,y) be the circumcentre of triangle. Then,

PR = PS = PT

PR² = PS²

(x-(-2))² + (y-5)² = (x-(-6))² + (y-5)²

(x+2)² + (y-5)² = (x+6)² + (y-5)²

x²+4x+4 + y²-10y+25 = x²+12x+36 + y²-10y+25

12x-4x = 36 -4

8x = 32

x = 32/8 = 4

Also, PS² = PT²

(x-(-6))² + (y-5)² = (x-(-2))² + (y-(-1))²

(x+6)² + (y-5)² = (x+2)² + (y+1)²

x²+12x+36 + y²-10y+25 = x²+4x+4 + y²+2y+2

12x-4x-10y-2y = 4+2-36-25

8x-12y = -55 .......(1)

put x= 4 into (1):

8x-12y = -55

8(4)-12y = -55

32 -12y = -55

-12y = -55-32

-12y = -87

y = 7.25

The required linear function in slope intercept form is C = 5x + 20

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex]  is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan \theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

The amount of $34.65 is deducted from Ron’s gross wages for social security at 6.2% and Medicare at 1.5% .

Percentage means one part of every cent or hundred. And it is represented by symbol '%'.

Given that Ron earns $450 in gross wages on January 10.

To find deduction amount from Ron’s gross wages for social security at 6.2% ;

Firstly, we find  6.2% of $450 that is $450 x 6.2 / 100 = $27.9 and then we substract to the gross wages.

$450 - $27.9 = $422.1

Now to find 1.5 % of $450 that is 450 x 1.5/ 100 = $6.75 and then we substract to the gross wages.

$450 - $6.75 = $443.25

total deduction amount is $6.75 + $27.9 = $34.65

Therefore, $34.65 is deducted from Ron’s gross wages for social security at 6.2% and Medicare at 1.5%

Assuming the population standard deviation is known and the standard deviation of the sample mean x : option (b) is correct : the standard error of the sample mean decreases.

In probability theory, the central limit theorem (CLT) states that the distribution of a sample variable approximates a normal distribution (i.e., a “bell curve”) as the sample size becomes larger, assuming that all samples are identical in size, and regardless of the population's actual distribution shape.

Standard deviation is a calculation of the dispersion or variation in a set of numbers. If the standard deviation is a small number, it means the data points are close to their average value. If the deviation is large, it means the numbers are spread out, further from the mean or average.

There are different ways to write out the steps of the population standard deviation calculation into an equation. A common equation is:

                          σ = ([Σ(x - u)2]/N)1/2

Where:

σ is the population standard deviation

Σ represents the sum or total from 1 to N

x is an individual value

u is the average of the population

N is the total number of the population

A sample mean is an average of a set of data . The sample mean can be used to calculate the central tendency, standard deviation and the variance of a data set. The sample mean can be applied to a variety of uses, including calculating population averages.

True, With an 80-person sample size, we are selecting from a skewed-right distribution, hence the sampling distribution mean should likewise be skewed-right.

80 people make up the sample that was taken from the population distribution with a right skew. We may infer that the sampling distribution of the sample means would be close to normalcy given the size of the sample.

In general, the distribution is normal.

The central limit theorem states that as sample size increases, the sample mean distributions become normal, with standard deviations equaling n and mean values approximating the population mean, regardless of the underlying distribution's form. In other words, the sample means sampling distribution turns roughly normal.

a) The probability that a sample of taxpayers from this income group who have itemized deductions will show a sample mean within $210 of the population mean is 0.9482.

b) When trying to estimate the population mean, a greater sample size offers the benefit of improving the estimation's accuracy.

a. The z-score is calculated as follows:

z = (x - μ) ÷ (σ ÷ √n)

Where the sample size is n, the sample mean is x, the population mean is y, and the population standard deviation is z.

By entering the specified values, we obtain:

n = 30: z = (x - 17,545) ÷ (2,160 ÷ √30) = (x - 17,545) ÷ 216

n = 50: z = (x - 17,545) ÷ (2,160 ÷ √50) = (x - 17,545) ÷ 174

n = 100: z = (x - 17,545) ÷ (2,160 ÷ √100) = (x - 17,545) ÷ 132

n = 400: z = (x - 17,545) ÷ (2,160 ÷ √400) = (x - 17,545) ÷ 53

To find the odds that a sampling distribution could be within $210 of both population mean and the z-score, we must first figure out the likelihood that now the z-score would be within 1.96 standard deviations of the mean. This is because the 95th percentile, or the number under which 95% of the data lies, is represented by the z-score of 1.96, which is the value in this case.

To ascertain the likelihood, we must attempt searching up the z-scores in a z-table and get the pertinent probabilities. A z-table is a table that lists the probability associated with various z-scores.

Using the z-scores we used to develop the concept, we could look up the alternatives in a z-table and find the following probability:

n = 30: 0.4056

n = 50: 0.5082

n = 100: 0.6690

n = 400: 0.9482

For each of the aforementioned sample sizes, the likelihood that a sampling of taxpayers from this income category who itemized deductions will exhibit a sample mean that is within $210 of the population mean is:

n = 30: 0.4056

n = 50: 0.5082

n = 100: 0.6690

n = 400: 0.9482

b. The likelihood that the sample means will closely match the true population mean is thereby increased.

The standard deviation averages commonly fall as the sample size rises. In other words, as the sample mean becomes less likely to depart from the actual population mean, the likelihood that the random variable will be close to the population mean increases.

For instance, in the aforementioned case, the likelihood that they would give it a shot would be within 210 of a population mean would rise from 0.4056 for a random sample of just 30 to 0.9482 for a random sample of 400.

This means that the likelihood that they give it a chance will fall within the allowed range of the sample % likewise increases as the sample size increases.

Applying the definition of midpoint, the measure of angle GIH in the triangle shown is: 59°.

The corresponding angles of two similar triangles are always congruent to each other.

Given that H is the midpoint of Eg and I is the midpoint of FG, two similar triangles are created, where angles GFE and GIH are corresponding angles.

Given:

m∠GFE = 87 - 7x

m∠GIH = 51 + 2x

m∠GFE = m∠GIH [corresponding angles are congruent]

Substitute

87 - 7x = 51 + 2x

Solve for x

-2x - 7x = 51 - 87

-9x = -36
