The 10th term of the geometric sequence whose common ratio is 1/3 and whose first term is 7 is [tex]\frac{7}{19683}[/tex].

What is  geometric sequence?

A unique kind of sequence is a geometric sequence. Every term in the series (apart from the first term) is multiplied by a fixed amount to determine the following term. In other words, we multiply the current phrase in the geometric sequence by a constant term (called the common ratio), and then divide the current term in the geometric sequence by the same common ratio to discover the previous term in the geometric sequence.

nth term of geometric series

a(n) = a(1) * r^(n-1)

You are given a(1) = 7, r = 1/3 and n = 10.

a(10) = 7 * 1/3^(10-1)

Step-by-step explanation:

The horizontal component is [tex]-3[/tex] and the vertical component is [tex]4[/tex]

The component (-3, 4) from the given vectors are shown ​in the graph.

Let A = v 1, v 2,..., v r be a collection of vectors from Rn. If r > 2 and at least one of the vectors in A can be expressed as a linear combination of the others, A is said to be linearly dependent. The rationale for this description is straightforward: at least one of the vectors is dependent (linearly) on the others. If no vector exists in A, the set is said to be linearly independent. It is also usual to state "the vectors are linearly dependent (or independent)" rather than "the set comprising these vectors is linearly dependent (or independent)."

We have been given that the graph in the question

The salary corresponding to z=1 is $64587 if the average teacher's salary in a particular state is $54,137.

A Z-score is a metric that quantifies the connection between a value and the mean of a set of values. The Z-score is measured as the standard deviations from the mean. If the Z-score is 0, A data point's score is the same as the mean score. In statistics, a raw score's value that deviates or surpasses the mean of the phenomenon being observed or measured is referred to as the standard score. Raw scores above the mean are given positive standard scores, whilst raw values below the mean are given negative standard ratings.

The pay is 1 standard deviation above the mean, according to a z score of 1.

Therefore, the salary for a z-score of 1 is:

$54,137 + 1($10,450) = $64587

The width of the bedroom is 17 feet. The length of the bedroom is 17 + 8 = 25 feet.

What is the area of the rectangle?

The area of the rectangle is length x breadth. The diagonals of the rectangle divide it into two equivalent right-angled triangles. Therefore, the area of the rectangle will be equal to the sum of the area of these two triangles.

Let w be the width of the bedroom and l be the length of the bedroom.

The width of the bedroom is 8 feet shorter than the length, so the length is w + 8.

The area of the bedroom is the product of its width and length, or w * (w + 8).

We can set up the equation 425 = w * (w + 8) and solve for w.

First, we can rewrite the equation as 425 = w^2 + 8w.

Then, we can complete the square by adding (8/2)^2 = 16 to both sides:

425 + 16 = w^2 + 8w + 16

441 = w^2 + 8w + 16

We can rewrite the left side of the equation as (w + 4)^2, which gives us:

(w + 4)^2 = 441

Taking the square root of both sides gives us:

w + 4 = 21

Subtracting 4 from both sides gives us:

w = 17

Therefore, the width of the bedroom is 17 feet. The length of the bedroom is 17 + 8 = 25 feet.

Answer:

2x+3y = -15

Step-by-step explanation:

The linear equation written in the slope-intercept form is:

y = (-3/5)*x

The correct option is C.

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

Here we can see that the line crosses through the poin (0, 0), so the y-intercept is 0.

b = 0

y = a*x + 0

y = a*x

To find the value of a, we can use another point on the graph.

We can see that the linear equation passes through (5, - 3), replacing these values:

-3 = a*5

-3/5 = a

Then the linear equation is just:

(where x is the original length of the pipe).

Original length of the pipe = 16 feet

Step-by-step explanation:

Let x be the original length of the pipe.

Given a plumber cuts 2 3/4 feet from a pipe and now has a pipe that is 13 1/4 feet long, the equation that models this is:

[tex]\boxed{ x-2 \frac{3}{4}=13 \frac{1}{4}}[/tex]

To determine the length of the original pipe, solve the equation for x.

Add 2 3/4 to both sides of the equation:

[tex]\implies x-2 \frac{3}{4}+2 \frac{3}{4}=13 \frac{1}{4}}+2 \frac{3}{4}[/tex]

[tex]\implies x=13 \frac{1}{4}}+2 \frac{3}{4}[/tex]

When adding mixed numbers, partition the mixed numbers into fractions and whole numbers, and add them separately:

[tex]\implies x=13 +\dfrac{1}{4}}+2 +\dfrac{3}{4}[/tex]

[tex]\implies x=13 +2 +\dfrac{1}{4}}+\dfrac{3}{4}[/tex]

[tex]\implies x=15 +\dfrac{1+3}{4}[/tex]

[tex]\implies x=15 +\dfrac{4}{4}[/tex]

[tex]\implies x=15 +1[/tex]

1. Correlation is a bivariate analysis that measures the strength of association between two variables and the direction of the relationship. Regression is a statistical method to determine the strength and character of the relationship between one dependent variable and a series of other variables (known as independent variables). So, both correlation and regression require a measure for both variables individual variances.

2. We can test for the statistical significance of a correlation coefficients by performing a hypothesis test on the correlation coefficients. And it's also possible to perform hypothesis tests on the regression slope on the values which is being estimated using a regression analysis. So, both correlation and regression can be tested for statistical significance.

3. Correlation helps us to test the strength of association between two variables. But regression helps us to predict one of the variables from the other. So, it is true for a regression.

To proof : f is not one-one function

Let us assume for the sake of contradiction that f is one to one function

Let n and m be positive integers such that |S| = n and |T| = m.

Note that these integers need to exist as S and T are finite sets

n > m

Let S = {s1 , . . . , sn} and T = { t1 , . . . , tm}

Without loss of generality , we can assume that f(si) = ti , for i = 1, 2, 3 ....

as each element needs to have a unique image ( since , f is one to one ) and we can rename the element t1 , . . . , tm if the order of the elements didnt match up the images.

Since , n > m we have a term sm+1 while we do not have a term t m+1 .

This implies that sm+1 needs to have a same image as some sk

f(sm+1) = f(sk) = tk

However , f(sm+1) = f(sk) = tk is then in contradiction with the fact that f is one-to-one.

a. The inverse variation relationship between a and b can be expressed as a = k/b^2, where k is a constant. We are given that a is 1 when b is 3, so we can substitute these values into the equation to find k: 1 = k/(3^2). Solving for k, we get k = 9.

Substituting this value of k back into the equation a = k/b^2, we can find a when b is 5: a = 9/(5^2) = 9/25 = 0.36. Therefore, a is 0.36 when b is 5.

b. To find the distance it takes for a car traveling at 65 miles per hour to stop, we can use the equation for direct variation: d = kv^2, where d is the distance, v is the speed, and k is a constant. We are given that it takes 112 feet for a car traveling at 40 miles per hour to stop, so we can substitute these values into the equation to find k: 112 = k(40^2). Solving for k, we get k = 0.0056.

Substituting this value of k back into the equation d = kv^2, we can find the distance it takes for a car traveling at 65 miles per hour to stop: d = 0.0056(65^2) = 2256 feet. Therefore, it takes 2256 feet for a car traveling at 65 miles per hour to stop.

A standard normal distribution's characteristics are its mean is equal to 0 and the standard deviation is 1. Thus, the variance is equal to 1.

A normal distribution that has a mean value of 0 and a standard deviation or a variance of 1 is said to be a standard normal distribution.

I.e., μ = 0 and σ² = 1

This is also called z-distribution.

A standard normal distribution has μ = 0 and σ² = 1.

So, the probability of a normal random variable is calculated by using a z-score.

The z-score value is calculated by the formula

z = (X - μ)/σ

Where mean (μ) and standard deviation (σ) for the variable X

By using the standard normal distribution tables with the z-score and probabilities, the required values are calculated.

Answer:

18 miles

Step-by-step explanation:

To determine how many miles Brent can travel, we need to first determine the cost of the base fare and then subtract that from the total amount of money Brent has. The base fare is $1.23, so we can subtract that from the total amount of money Brent has to find out how much money he has left for the per-mile charge:

14.91 - 1.23 = 13.68

Now that we know how much money Brent has left for the per-mile charge, we can divide that amount by the per-mile charge to find out how many miles Brent can travel:

13.68 / 0.76 = 18 miles

Therefore, Brent can travel a maximum of 18 miles given the amount of money he has available to spend on the ride.
