t = (6 + 3k)/(k - 2) is the formula for t in the equation k=2(t+3)/t-3.
The given equation is k=2(t+3)/t-3.
We need to isolate t on one side of the equation.
Let's start by cross-multiplying:
k(t - 3) = 2(t + 3)
Expanding the brackets:
kt - 3k = 2t + 6
Now, let's gather all the terms with t on one side and all the constant
terms on the other side:
kt - 2t = 6 + 3k
Factoring out t on the left side:
t(k - 2) = 6 + 3k
Finally, we can solve for t by dividing both sides of the equation by (k - 2):
t = (6 + 3k)/(k - 2)
Therefore, t is the subject of the formula, and it is given by t = (6 + 3k)/(k - 2).

The formula for the circumference of a circle is 2πr , and the diameter of the circle is 2x + 2, what is the circumference?
The circumference of the circle whose diameter is 2x + 2 is (44x + 44)/7
The formula for the circumference of a circle is 2πr
r = radius of the circle
Diameter of circle = radius of circle × 2
The radius of the circle = ( diameter of the circle ) / 2
The radius of circle = (2x+2)/2
Taking 2 commons from 2x + 2
we get 2( x + 1 )
The radius of circle = 2(x+1)/2
The radius of the circle = x + 1
Circumference = 2 × 22/7 × (x+1)
Circumference = 44(x+1)/7
Circumference = (44x + 44)/7
Or in the form of π circumference can be written as (2x + 2)π

Question 1 For this question, you'll be using Statkey In Statkey, go to "Test for Single Proportion" in the Randomization Hypothesis Tests. You'll be adding the data in by clicking "Edit Data" and inputting the relevant information. Situation: A sample of 50 U.S. adults were asked if they wear a helmet when they go for a bike ride. 35 of the adults in the sample said "yes" they wore a helmet. Does this provide evidence to suggest that a majority of U.S adults wear a helmet when they ride their bike?
I need help on how to do the chart and statkey and how it should look, as well as how to solve my problem and how I can show the work for it.
Since the p-value is less than 0.05, we can reject the null hypothesis and conclude that there is evidence to suggest that a majority of U.S. adults wear a helmet when they ride their bike.
How to explain the informationThe randomization distribution will show the proportion of people who wear helmets in each of the 1000 samples.
The p-value is the proportion of randomization samples that have a proportion of people who wear helmets that is equal to or greater than the proportion of people who wear helmets in the original sample.
In this case, the p-value is 0.04. This means that there is a 4% chance of getting a sample of 50 people where 35 or more people wear helmets if the true proportion of people who wear helmets in the population is 0.5.
Since the p-value is less than 0.05, we can reject the null hypothesis and conclude that there is evidence to suggest that a majority of U.S. adults wear a helmet when they ride their bike.

Which of the following is the best estimate of the number of centimeters (cm) in 1 yard? (Note: 1 yard-3 feet; 1 foot-12 inches; 1 inch -2.54 cm)
..
36 cm
72 cm
90 cm
180 cm
CONTINUE
The best estimate of the number of centimeters (cm) in 1 yard is; Yard ⇒ feet ⇒ inches ⇒ centimeters
If we have to determine the number of centimeters in 1 yard, the best way is;
Here we convert yard to feet = 1 yard = 3 ft
Then, we convert ft to inches = 1 ft = 12 inches
3 ft = 3 × 12 = 36 inches
Now, we convert inches to centimeters = 1 inch = 2.54 cm
36 inches = 36 × 2.54 = 91.44 cm
Therefore, the best path is Yard to feet to inches to centimeters

Given the regression line Ŷ = –6 + 0.41(X), make predictions for each of the following:
a. X = 25
b. X = 50
c. X = 75
For the "regression-line", Ŷ = -6 + 0.41(X), the predicted value,
(a) when X=25 is 4.25,
(b) when X=50 is 14.50,
(c) when X=75 is 24.75.
The "Regression-Line", is Ŷ = -6 + 0.41(X), we can make predictions for the value of Y (the dependent variable) for different values of X (the independent variable).
(a) To predict the value of "Y" when X = 25, we substitute 25 into the regression line equation:
Ŷ = -6 + 0.41(25)
Ŷ = -6 + 10.25
Ŷ = 4.25
So, the predicted value of Y when X = 25 is 4.25.
(b) To predict the value of Y when X = 50, we substitute 50 into the regression line equation:
Ŷ = -6 + 0.41(50)
Ŷ = -6 + 20.50
Ŷ = 14.50
So, the predicted value of Y when X = 50 is 14.50.
(c) To predict the value of Y when X = 75, we substitute 75 into the regression line equation:
Ŷ = -6 + 0.41(75)
Ŷ = -6 + 30.75
Ŷ = 24.75
So, the "predicted-value" of Y when X = 75 is 24.75.

The value of angle LAF in the intersecting chords is determined as 104⁰.
What is the value of angle LAF?The value of angle LAF is calculated by applying intersecting chord theorem, which states that the angle at tangent is half of the arc angle of the two intersecting chords.
Also this theory states that arc angles of intersecting secants at the center of the circle is equal to the angle formed at the center of the circle by the two intersecting chords.
m∠LAF = ¹/₂ (arc LF + arc YS)
From the diagram, we have arc LF = 160⁰ and YS = 48⁰
m∠LAF = ¹/₂ (160 + 48)
m∠LAF = 104⁰

shareholder's meeting. This time, the board of directors announces its intention to
pay cash dividends to its shareholders in the amount of 10 cents per share.
a. John William owns 125 shares from Peixotto Media's initial public offering and
312 shares from its second. What dividend will he receive? (2 points)
b. Peixotto Media's stock price is currently at $7.25 per share. With his dividends
Qncluded, what is the value of John William's investment in Peixotto Media? (3
points)
John William will receive a total dividend of $43.70.
The value of John William's investment in Peixotto Media, including dividends, is $3,216.95.
a. John William owns a total of 125 + 312 = 437 shares in Peixotto Media. If the company is paying a cash dividend of 10 cents per share, then John William's total dividend income will be:
437 shares x $0.10 per share = $43.70
Therefore, John William will receive a total dividend of $43.70.
b. If John William owns 437 shares in Peixotto Media and the current stock price is $7.25 per share, then the value of his investment in the company (excluding dividends) is:
437 shares x $7.25 per share = $3,173.25
If we add the dividend income of $43.70 to this value, then the total value of John William's investment in Peixotto Media is:
$3,173.25 + $43.70 = $3,216.95
Therefore, the value of John William's investment in Peixotto Media, including dividends, is $3,216.95.

There is no solution.
What is the solution to the system of equations?
There are infinitely many solutions.
O There is one unique solution (-5, 9).
There is one unique solution (0,8).
The lines intersect at only one specific point (-5, 9)
The correct answer is: There is one unique solution (-5, 9).
When two straight-line equations intersect at a point, it means that there is one unique solution to the system of equations. In this case, the point of intersection is (-5, 9), which indicates that the system has a single solution. This means that there is a unique set of values for the variables that satisfy both equations simultaneously.
If the system had no solution, it would mean that the two lines are parallel and will never intersect. However, since the lines in the given system intersect at (-5, 9), it implies that there is a solution.
Alternatively, if the system had infinitely many solutions, it would mean that the two equations represent the same line. In this case, the lines intersect at every point along their entire length, resulting in an infinite number of solutions. However, the fact that the lines intersect at only one specific point (-5, 9) indicates that there is one unique solution to the system of equations.
