C

Step-by-step explanation:

Multiplying the sequence by 2 gives us the next term. Therefore it has to be the formula a1 x r^n-1. If we substitute the values it would end up as the answer C

Answer:

The correct answer would be option C; 12 x 2ⁿ⁻¹

Step-by-step explanation:

You can check this using any number

since n is the term number we can check it;

let's say we have to find out the answer to the third term number, so we will substitute the n by 3 in the equation from option C and solve

term = 12 x 2ⁿ⁻¹

term = 12 x 2 ³ ⁻¹

term = 12 x 2 ²

term = 12 x 4

term = 48

The term does match the third number in the series given above and hence the equation works!

The ACT score a student should have in order to be in the top 5% of test takers is 30.253 (rounded to 3 decimal places).

We are given a normal distribution with mean µ = 24 and standard deviation σ = 3.8.

We need to find out the ACT score which a student should have to be in the top 5% of test takers.

To find the ACT score, we will use the Z-score formula:

z = (X - µ) / σWe know that for the top 5% of the test takers, the area under the curve should be equal to 0.05.

Therefore, we can use a standard normal distribution table to look up the corresponding z-score.z-score for the top 5% of test takers = 1.645

We need to find the ACT score, X.So, the formula becomes:1.645 = (X - 24) / 3.8

Let's solve for X.X - 24 = 1.645 × 3.8X - 24 = 6.253X = 24 + 6.253X = 30.253

Therefore, the ACT score a student should have in order to be in the top 5% of test takers is 30.253 (rounded to 3 decimal places).

Given the number:

0.0002077​

Let's express in scientific notation.

To express the number in scientific notation, move the decimal point so that there is only one non-zero number to the left of the decimal point.

Then, the number of decimal places you move will be the exponent on 10.

If the decimal point is moved to the right, the exponent will be negative.

If the decimal pointt is moved to the left, the exponent will be positive.

In this case the decimal point will be moved to the right.

Using this description, we have the scientific notation below:

Answer:

2.077 x \(10^{-4}\)

Step-by-step explanation:

First, move the decimal place until we have a single digit between 1 and 10 to the left of the decimal point. In this problem, if we keep moving the decimal point to the right in 0.0002077 we will get 2.077.

Next, count how many places we moved the decimal point. If we have to move the decimal place to the right, the exponent will be negative.  If we had moved the decimal place to the left, the exponent would be positive.  In this case we had to move it 4 places to the right to change 0002077 to 2.077. We show that we moved it 4 places to the right by noting that the number should be multiplied by \(10^{-4}\).

The equilibrium point for the supply and demand equations p² + 4q = 253 and 183p² + 6q = 0 is (q, p) = (3, 10).

To find the equilibrium point, we need to solve the system of equations formed by the supply and demand equations. By substituting the value of q = 3 into the first equation, we get p² + 4(3) = 253, which simplifies to p² + 12 = 253.

Solving this equation gives us p = 10. Substituting the values of q = 3 and p = 10 into the second equation, we get 183(10)² + 6(3) = 0, which simplifies to 18300 + 18 = 0.

Since this equation holds true, we have found the equilibrium point to be (q, p) = (3, 10), where the equilibrium quantity is q = 3 and the equilibrium price is p = 10.

Step-by-step explanation:

did you change the reference number ?

I think the original question was "90 is how many % of 80 ?"

now it is 81.

in % calculations the most important things to identify :

what are 100% (or any other reference % level).

then what is 1%.

and then multiply this 1% by the desired number of % or divide the target number by this 1% to find out how many % the target number is.

in our case here

100% = 81

1% = 100%/100 = 81/100 = 0.81

how many % are 90 ?

well, as many as how often 1% fits into these 90 :

90/0.81 = 111.111111111... %

when the reference was 80, then we had

90/0.8 = 112.5%

Answer:

Marta spent a total of $34.29

Step-by-step explanation:

Since she bought 3 towels for $8.50 each you would do 3 times $8.50 to get $25.50 for the towels and since she bought 5 washcloths for $1.25 each you would do 5 times $1.25 to get $6.25 then you would add the totals to get $31.75. Then you would find out the tax by finding out what 8% of $31.75 is which would be 2.54. So you would add $2.54 to $31.75 to get $34.29. So the total amount of money that Marta spent is $34.29

3 times $8.50 = $25.50

5 times $1.25 = $6.25

$25.50 + $6.25 = $31.75

The dimensions of the poster be so that the least amount of poster is used are A = 6L + 4W + 412.

Let the length and width of the printable area of the poster be L and W, respectively. Then, the total dimensions of the poster can be expressed as L + 2(2) and W + 2(1), since there are 2-inch margins at the top and bottom, and 1-inch margins on the left and right.

We know that the area of the printable area of the poster is 392 square inches. Therefore, we can write the equation: LW = 392

We want to minimize the total area of the poster, which is given by:

A = (L + 2(2))(W + 2(1)) = (L + 4)(W + 2)

Expanding this expression, we get:

A = LW + 2L + 4W + 8

Substituting the equation for LW, we get:

A = 392 + 2L + 4W + 8

Simplifying, we get:

A = 2L + 4W + 400

To minimize this expression, we can take the partial derivatives with respect to L and W and set them equal to zero:

\(∂A/∂L = 2 = 0 => L = 0\)

\(

∂A/∂W = 4 = 0 => W = -100\)

These values do not make sense in the context of the problem. Therefore, we can conclude that the dimensions of the poster that minimize the amount of poster used cannot be found using this method.

Instead, we can use the fact that the printable area of the poster has a fixed area of 392 square inches, and that the margins have fixed dimensions. We can express the area of the poster as:

A = (L + 4)(W + 2) = LW + 4L + 2W + 8

Substituting the equation for LW, we get:

A = 392 + 4L + 2W + 8

Simplifying, we get:

A = 4L + 2W + 400

To minimize this expression, we can again take the partial derivatives with respect to L and W and set them equal to zero:

\(∂A/∂L = 4 = 0 => L = 0\)

\(∂A/∂W = 2 = 0 => W = -200\)

These values do not make sense in the context of the problem. Therefore, we can conclude that the dimensions of the poster that minimize the amount of poster used cannot be found using this method either.

We can try a different approach. We can use the fact that the printable area of the poster has a fixed area of 392 square inches, and that the total area of the poster is given by:

A = (L + 4)(W + 2) + 2(L + 4) + 2(W + 2)

Expanding this expression, we get:

A = LW + 6L + 4W + 20

Substituting the equation for LW, we get:

A = 392 + 6L + 4W + 20

Simplifying, we get: A = 6L + 4W + 412

To minimize this expression, we can take the partial derivatives with respect to L and W and set them equal to zero:

\(∂A/∂L = 6 = 0 => L = -2/3\)

\(∂A/∂W = 4 = 0 => W = -3/2\)

Answer:

When x = 6, y is 17

When x = 12, y is 14

The equation of the line is D

Step-by-step explanation:

2x + 4y = 80  Subtract 2x from both sides

2x - 2x + 4y = 80 - 2x

4y = 80 - 2x  Divide both sides by 4

y = 20 - 2/4 x

y = 20 - 1/2x

Substitute x with 6

y = 20 - 1/2(6)

y = 20 - 3

y = 17

Substitute x with 12

y = 20 - 1/2(12)

y = 20 - 6

y = 14

The value of the series, to within an error of at most 10^(-3), is approximately -1.

To approximate the value of the series ∑n=1 to infinity (-1)^n / (n^2)(n^6) within an error of at most 10^(-3), we can use the Alternating Series Estimation Theorem.

The Alternating Series Estimation Theorem states that for an alternating series ∑(-1)^n b_n, where b_n is a positive sequence that approaches zero as n approaches infinity, the error when approximating the sum of the series with the nth partial sum is less than or equal to the absolute value of the (n+1)th term.

In this case, b_n = 1 / (n^2)(n^6), which is a positive sequence that approaches zero as n approaches infinity. Therefore, we can use the theorem to find an appropriate value of n that ensures the error is within the desired tolerance.

Let's set the (n+1)th term to be less than or equal to 10^(-3):

\(1 / ((n+1)^2)((n+1)^6) < = 10^-3\)

Simplifying the inequality:

\(1 / ((n+1)^8) < = 10^-3\)

Taking the reciprocal of both sides:

\((n+1)^8 > = 10^3\)

Taking the eighth root of both sides:

\(n+1 > = (10^3)^1/8\)

\(n+1 > = 10^(3/8)\)

\(n > = 10^(3/8) - 1\)

Using a calculator, we can approximate the right-hand side:

n >= 1.568 - 1

n >= 0.568

Since n must be a positive integer, the smallest value of n that satisfies the inequality is n = 1.

Therefore, using the first term of the series, the approximation of the series within an error of at most \(10^-3\) is:

\((-1)^1 / (1^2)(1^6) = -1\)

So the value of the series, to within an error of at most \(10^-3\), is approximately -1.

The type of error that occurred in the statistical test is a Type I error (false positive).

In the given scenario, the statistical test resulted in the conclusion that the average time for processing a claim exceeds 5 days. However, it is later discovered that the mean process time does not actually exceed 5 days. Based on this information, the type of error that occurred in the statistical test is a Type I error.

Type I error, also known as a false positive, refers to rejecting the null hypothesis when it is actually true. In this case, the null hypothesis stated that the average time for processing a claim is not more than 5 days. However, due to some statistical variability or other factors, the test incorrectly led to the rejection of the null hypothesis, concluding that the average time does exceed 5 days.

In reality, when it was later discovered that the mean process time does not exceed 5 days, it indicates that the initial conclusion drawn from the statistical test was incorrect. This erroneous conclusion could have been caused by various factors such as sampling variability, measurement errors, or other random fluctuations in the data.

It is important to note that Type I errors can occur in hypothesis testing, and they represent the risk of incorrectly rejecting a true null hypothesis. In this case, the insurance company made a Type I error by concluding that the average processing time exceeds 5 days, even though it was not the case.

I don’t understand:/

if the tangent line to y = f ( x ) at ( 6 , 2 ) passes through the point ( 0 , 1 ) , then f(6) = 2 and f'(6) = 1/6.

To find f(6), we can use the fact that the tangent line to y = f(x) at (6, 2) passes through the point (0, 1). The equation of a line can be written as y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line.

Since the line passes through (6, 2) and (0, 1), we can substitute these values into the equation to get:

2 - 1 = m(6 - 0)

1 = 6m

Solving for m, we find m = 1/6.

Since the slope of the tangent line is equal to the derivative of f(x) at x = 6, we have f'(6) = 1/6.

Now, to find f(6), we can integrate f'(x) with respect to x:

f(x) = ∫(f'(x))dx = ∫(1/6)dx = (1/6)x + C

To find the value of C, we can substitute the point (6, 2) into the equation:

2 = (1/6)(6) + C

2 = 1 + C

C = 1

Therefore, f(x) = (1/6)x + 1.

Substituting x = 6 into the equation, we get:

f(6) = (1/6)(6) + 1 = 2.

So, f(6) = 2 and f'(6) = 1/6.

The width of the rectangle is 5 meters.

To find the width of the rectangle, let's use the formula for the area of a rectangle, which is:

Area = length x width

We know that the area of the rectangle is 65 square meters. We also know that the length of the rectangle is 8 meters more than the width. Let's call the width "w". Then, the length can be expressed as:

length = w + 8

Substituting this expression for length into the formula for the area, we get:

65 = (w + 8) x w

Simplifying and solving for w, we get:

w² + 8w - 65 = 0

Using the quadratic formula, we get:

w = (-8 ± √(8² + 4(1)(65))) / (2(1))

w = (-8 ± √(324)) / 2

w = (-8 ± 18) / 2
