The members of a small town’s local arts council are selling raffle tickets. The art council decides that the top three raffle ticket sellers will share a portion of the profits. The second-place seller will receive twice as much as the third-place seller. The first-place seller will receive $20 more than the second-place seller. The profit portion they will share is $200
If there were a 4th place prize and that 4th place winner received half of what 3rd place received. How much is the 4th place prize?

Answers

The  prize of the 4th place is 18

How to determine the prize of the 4th place?

Given:

1. The second-place seller will receive twice as much as the third-place seller

2. The first-place seller will receive $20 more than the second-place seller

3. The profit portion they will share is $200

Let S, T, F and V represent the prize of the second, third, first and fourth  place respectively

Statement 1 can be written as:

S = 2T  --- (1)

Statement 2 can be written as:

F = S + 20  --- (2)

Statement 3 can be written as:

F + S + T = 200  --- (3)

Substitute (1) and (2) into (3):

F + S + T = 200

(S+20) + 2T + T= 200

(2T+20) +2T + T= 200          (Since S = 2T)

2T+20 +2T + T= 200

5T + 20 = 200

5T = 200-20

5T = 180

T = 180/5

T = 36

Thus, the third-place seller prize is 36

Since the 4th place winner received half of what the 3rd place received. Thus:

V = 1/2 × T

V =  1/2 × 36

V = 18

Therefore, the 4th place prize is 18

What is Graph Transformation?

When a graph is transformed, the graph's curve either "moves to the left/right/up/down," "expands or compresses," or "reflects." For instance, by simply pushing the graph of the function g(x) = x2 up by 3 units, the graph of the function f(x) = x2 + 3 is generated. graph transformations are highly useful for graphing functions without having to start from scratch since they allow you to move, extend, compress, or reflect the curve. The graph of the parent function is either "moved," "resized," or "reflected" by a graph transformation. The three primary categories of graph transformations are as follows:

Solve for the formula for the indicated variable. A= 1/2 bh, for h

Answers

The value of the h is A(2) / b when the formula is A = 1/2bh the formula is area of the triangle.

Given that,

We have a formula A = 1/2bh

We have to find h value from the formula.

We know that,

The variable h should be on one side of the equation, and the rest should be on the other. Divide the two sides in half as a good place to start. In this way, we eliminate the undesirable fraction.

A / 1/2 = 1/2bh / 1/2

Now on the right hand side left the 1/2 cancels out.

A / 1/2 = bh

And when a fraction is divided, the result is the same as multiplying it backwards.

A(2/1) = bh

Now, divide both sides by b.

A(2) / b = bh/b

On the left hand side b cancels out and we are left with the final product.

h = A(2) / b

Therefore, The value of the h is A(2) / b when the formula is A = 1/2bh the formula is area of the triangle.

A line's steepness can be determined by looking at its slope. Slope is determined mathematically as increase over run.

How do you find slope of a line?

According to the slope equation, the slope of a line may be calculated by dividing the rise of the line between any two places by the run of the same line between the same two sites.

The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.

Slope of y =f(x)

USA Today reported that the state with the longest

A random sample of 20 obituary notices in the Honolulu Advertizer gave the
following information about life span (in years) of Honolulu residents:
72 68 81 93 56 19 78 94 83 84
77 69 85 97 75 71 86 47 66 27
i. Use a calculator with mean and standard deviation keys to verify that
x 5 71.4 years and s < 20.65 years.
ii. Assuming that life span in Honolulu is approximately normally distributed, does this information indicate that the population mean life span for
Honolulu residents is less than 77 years? Use a 5% level of signifi cance.

Answers

There is not enough evidence to conclude that the population mean life span for Honolulu residents is less than 77 years.

What are the hypothesis tested?

At the null hypothesis, it is tested if there is not enough evidence that the mean life span is less than 77 years, that is:

[tex]H_0: \mu \geq 77[/tex]

At the alternative hypothesis, it is tested if there is enough evidence that the mean life span is less than 77 years, that is:

[tex]H_1: \mu < 77[/tex]

We are testing if the mean is less than a value, hence we have a left-tailed test, with 20 - 1 = 19 df and a significance level of 0.05, thus the critical value is of:

t = -1.7291.

Thus the conclusion, considering the test statistic t, is given as follows:

t > -1.7291: not enough evidence to conclude that the mean life span is less than 77 years -> do not reject the null hypothesis.t < -1.7291: enough evidence to conclude that the mean life span is less than 77 years -> reject the null hypothesis.

What is the test statistic?

The equation to obtain the test statistic is presented as follows:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

The parameters are:

[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.s is the standard deviation of the sample.n is the sample size.

In the context of this problem, the values of these parameters are given as follows:

[tex]\overline{x} = 71.4, \mu = 77, s = 20.65, n = 20[/tex]

Hence the test statistic is of:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{71.4 - 77}{\frac{20.65}{\sqrt{20}}}[/tex]

Find ED if AC=9x+1 and BD=13x-11 and ABCD is a rectangle.

Answers

ED = 14

Since ED splits the diagonal BD in half, we can set up an equation for later: ED = (1/2)BD.

Now, both BD and AC are diagonal lines that are congruent. This can be shown in this equation: AC = BD. Then, substitute the given information into it: 9x+1 = 13x-11 and solve!

Combine like terms and isolate the variable (see photo). And we find that x = 3.
Plug in this x value into the equation for BD = 13(3)-11 and find that BD = 28.

Back to the first equation we made, ED = (1/2)BD. So, ED = (28/2) = 14.

ED = 14.

Using simplification by factorisation and division

(x² + 6x + 9)/(x² - 9) = (x + 3)/(x - 3) and (3x² - 9)/(x² - x - 6) = 3x/(x + 2)

How to simplify the equations by factorization

To simplify the equations, we shall factorize both the numerator and the denominator, and divide through by a common factor.

for the equation (x² + 6x + 9)/(x² - 9);

the numerator:

x² + 6x + 9 = x² + 3x + 3x + 9

x² + 6x + 9 = x(x + 3) +3(x + 3)

x² + 6x + 9 = (x + 3)(x + 3)

the denominator:

x² - 9 = x² - 3²

x² - 9 = (x + 3)(x - 3) {difference of two squares}

(x² + 6x + 9)/(x² - 9) = (x + 3)(x + 3)/(x + 3)(x - 3)

divide through by the common factor (x + 3)

(x² + 6x + 9)/(x² - 9) = (x + 3)/(x - 3)

For the equation; (3x² - 9)/(x² - x - 6)

the numerator:

3x² - 9 = 3x(x -3)

the denominator:

x² - x - 6 = x² -3x + 2x - 6

x² - x - 6 = x(x - 3) + 2(x - 3)

x² - x - 6 = (x + 2)(x - 3)

divide through by the common factor (x - 3)

(3x² - 9)/(x² - x - 6) = 3x/(x + 2)

Thus, (x + 3)/(x - 3) and 3x/(x + 2) are the results for simplifying (x² + 6x + 9)/(x² - 9) and (3x² - 9)/(x² - x - 6) respectively using factorization.

Is it ever possible to have a graph of a function that is
symmetric about the y-axis AND the origin? Explain your
thinking.

Answers

We know that,

By definition, no function is symmetrical about the x-axis (or any other horizontal line). Because the one flipped with respect to the horizontal violates the vertical line test.

On the other hand, functions can be symmetric about a vertical line or a point. In particular, functions symmetric about the y-axis are also "even" functions, and functions symmetric about the origin are also "odd" functions. Because of this correspondence between graph symmetry and function equality or oddness, "symmetry" in algebra is usually applied to the y-axis and the origin.

Answer:

  yes: f(x) = 0

Step-by-step explanation:

You want to know if a function exists that is symmetrical about the y-axis and the origin.

Symmetry

A graph is symmetrical about the y-axis if and only if ...

  f(-x) = f(x)

A graph is symmetrical about the origin if and only if ...

  f(-x) = -f(x)

For both conditions to be met, we must have ...

  f(x) = -f(x)

  2f(x) = 0 . . . . . add f(x)

  f(x) = 0 . . . . . . . divide by 2

The graph of f(x) = 0 will be symmetrical about the y-axis and the origin. (It is the x-axis.)

Functions in mathematics can be compared to the operations of a vending (soda) machine. When you put in a certain amount of money, you can select different types of sodas. Similarly, for functions, we input different numbers and we get new numbers as the result. Domain and range are the main aspects of functions. You can use quarters and one-dollar bills to buy a soda.

The machine will not give you any flavor of the soda if pennies are input. Hence, the domain represents the inputs we can have here, that is, quarters and one-dollar bills. No matter what amount you pay, you won't get a cheeseburger from a soda machine. Thus, the range is the possible outputs we can have here, that is, the flavors of soda in the machine.

The range is the set of possible output values, which are shown on the y-axis. The domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x -axis.
