After completing their trade, Store Owner A has 0 puzzles and 10 puppets, and Store Owner B has 30 puzzles and 0 puppets.

Here,

Let's assume the two toy store owners are Store Owner A and Store Owner B.

Before the trade, Store Owner A has 30 puzzles and 0 puppets, and Store Owner B has 0 puzzles and 10 puppets.

They agree to trade 30 puzzles for 10 puppets at a rate of 3 puzzles for each puppet.

So, for every 3 puzzles, Store Owner A will receive 1 puppet.

Store Owner A gives away 30 puzzles and receives 30 / 3 = 10 puppets.

After the trade, Store Owner A has 0 puzzles and 10 puppets.

Store Owner B gives away 10 puppets and receives 10 * 3 = 30 puzzles.

After the trade, Store Owner B has 30 puzzles and 0 puppets.

So, after completing their trade, Store Owner A has 0 puzzles and 10 puppets, and Store Owner B has 30 puzzles and 0 puppets.

Part A

If the number is n, then the expression is 7n+6.

Part B

Three times the sum of a number and 8.

Answer:

62.9643082106 degrees

Step-by-step explanation:

First, notice that triangle ABC is a right triangle. This allows us to use SIN, COS, and TAN to find the measure of angle A. Recall SOH CAH TOA, so SIN = OPPOSITE / HYPOTENUSE, COS = ADJACENT / HYPOTENUSE, and TAN = OPPOSITE / ADJACENT.

Looking at angle A, sides c and b correspond to hypotenuse and adjacent respectively. Therefore, we can use COS to set up an equation.

cos(A) = b/c

cos(A) = 5/11

A = arccos(5/11)

A = 62.9643082106 deg

In the give diagram, the value of f is 6.0

From the question, we are to determine the value of f

Using the law of sines, we can write that

[tex]\frac{f}{sinF} =\frac{e}{sinE}[/tex]

From the given information,

F = 27°

e = 13

E = 98°

Putting the parameters into the equation, we get

[tex]\frac{f}{sin(27)} =\frac{13}{sin(98)}[/tex]

[tex]\frac{f}{0.4540} =\frac{13}{0.9903}[/tex]

[tex]f=\frac{13 \times 0.4540}{0.9903}[/tex]

The value of n that satisfies the inequality is 6.

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Given:

4n − 12 < 2n + 2

For n= 6

4(6) - 12 = 12

2(6) + 2 = 14

Thus, n=6 satisfies

For n= 7

4(7) - 12 = 16

2(7) + 2 = 16

Thus, n=7 not satisfies

For n=8

4(8) - 12 = 20

2(8) + 2 = 18

Thus, n=8 not satisfies.

The sample space neeeded for the experiment to find the face cards is 52.

Given there is a standard deck of cards.

We have to finf the sample space needed for the experiment of finding the probability of face cards.

Probability is the chance  of happening an event among all the events that are possible. It lies between 0 and 1. The probability is the number of items divided by the total items.

Sample is a part of population. It is studied when the study of whole population is difficult to do.

Cards in a deck=52

Number of face cards is 12.

When we  draw a card from the deck then it might be a face card or not. So we have to draw all the cards of a standard deck because it might possible that face card is present at the end of deck.

Hence the sample size needed in the experiment is 52.

A measure of the strength of the relationship between two variables is referred to as the correlation coefficient.

To gauge the strength of the linear link between two variables, correlation coefficients are used.

For a value of correlation coefficient less than zero denotes a negative association, while a value greater than zero denotes a positive relationship.

Zero correlation coefficient means there is no correlation between the two variables under comparison.

A crucial idea in building diversified portfolios that may better resist portfolio volatility is the concept of a negative correlation, often known as an inverse correlation.

Since calculating the correlation coefficient takes time, it is frequently done by entering data into a calculator, computer, or statistics application.

Answer:

the slope of a line is parallel to the line is (3,-2)

(0,2)

Answer:

21.1

Step-by-step explanation:

sin 49 = x / 28

0.75470958 = x/28

x = 21.1

Answer:

x=18.4

y=35

Step-by-step explanation:

So to solve for x, you're going to use one of the six trigonometric functions (you really only need to use the three main ones, sin, cos, and tan, to solve these problems). In this case you know the adjacent of the angle 49 degrees, and the hypotenuse. There is a trigonometric function which is defined as: [tex]\frac{adjacent}{hypotenuse}=cos(\theta)[/tex]. So let's plug in the known values:

[tex]cos(49) = \frac{x}{28}[/tex]

Multiply both sides by 28

[tex]cos(49) * 28 = x\\[/tex]

Calculate cos(49) using a calculator (make sure it's in degree mode):

[tex]0.656 * 28 \approx x[/tex]

[tex]18.4 \approx x[/tex]

So the second problem, you need to use the inverse of one of the trigonometric function, which essentially takes what f(x) is, and returns x. So in this case we're looking for a trigonometric function that is defined using the opposite and adjacent side, which tan is. [tex]tan(\theta)=\frac{opposite}{adajcent}[/tex]. In this case opposite=19, and adjacent=27. So plug in the known values:

[tex]tan(y)=\frac{19}{27}[/tex]

Apply the inverse of tan to both sides

[tex]y=tan^{-1}(\frac{19}{27})[/tex]

Calculate inverse of tan of 19/27 using a calculator:

[tex]y\approx35[/tex]

The factorized form of the expression ( 2x² - x - 6 ) is ( 2x + 3 )( x - 2 ).

Hence, the missing values are 3 and 2 respectively.

Given the expression: 2x² - x - 6

First, we factor -1 out of -x

2x² - x - 6

2x² -1(x) - 6

Not that, -1 can also be written as 3-4

2x² + (3-4)x - 6

2x² + 3x - 4x - 6

Next, we group the first two terms and the last two terms and factor out the GCF

(2x² + 3x) - 4x - 6

x(2x + 3) - 2( 2x + 3)

Factor out the GFC which is ( 2x+3 )

The rational function that meets all the conditions is:

[tex]f(x) = \frac{-15}{(x - 3)*(x + 5)}[/tex]

A rational function is of the form:

[tex]f(x) = \frac{p(x)}{q(x)}[/tex]

As the horizontal asymptote is at y = 0, we know that the numerator can't depend on x, so it is just a constant.

p(x) = a

And we want to have two vertical asymptotes at x = 3 and x = -5, then q(x) becomes zero at these values, so we have:

q(x) = (x -3)*(x + 5)

At this point, the function is:

[tex]f(x) = \frac{a}{(x - 3)*(x + 5)}[/tex]

Finally, we know that the y-intercept is 1, then we need to solve:

[tex]f(0) = 1 = \frac{a}{(0 - 3)*(0 +5)} = \frac{a}{-15} \\\\-15 = a[/tex]

Then we conclude that our function is:
