Answer:

[tex]31.7^\circ[/tex]

Step-by-step explanation:

We use the property that the sin of the angle of a right triangle is the ratio of the side opposite that angle divided by the hypotenus

Therefore
[tex]\begin{aligned}\sin x & = \dfrac{2.1}{4}\\& = 0.525\\\end{aligned}\\\begin{aligned}x &= sin^{-1}(0.525)\\& = 31.7^\circ \end{aligned}[/tex]

well, let's take a looksie at what it would  have been had there not been a sale, so at regular price the washer and dryer are just 685.96 + 475.70 = 1161.66, well hell how much is 4.25% of that?

[tex]\begin{array}{|c|ll} \cline{1-1} \textit{\textit{\LARGE a}\% of \textit{\LARGE b}}\\ \cline{1-1} \\ \left( \cfrac{\textit{\LARGE a}}{100} \right)\cdot \textit{\LARGE b} \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{4.25\% of 1161.66}}{\left( \cfrac{4.25}{100} \right)1161.66} ~~ \approx ~~ 49.37[/tex]

now, since we know the appliances are going to be 20%, that means the appliaces sale price will be 100% - 20% = 80%, so 80% of the original price, well, we know the original price for those two is 1161.66, what's 80% of that?

[tex]\stackrel{\textit{80\% of 1161.66}}{\left( \cfrac{80}{100} \right)1161.66} ~~ \approx ~~ \stackrel{ sale~price }{929.33} \hspace{5em} \stackrel{\textit{4.25\% of 929.33}}{\left( \cfrac{4.25}{100} \right)929.33} ~~ \stackrel{ \textit{Paula's commission} }{\approx ~~39.5}[/tex]

well, Paula could have made 49.37, but she ended up with 39.5, 49.37 - 39.5 ≈ 9.87.

The answer is (i) The statement is False, (ii) The statement is false, (iii) The statement is true, (iv) The statement is true.

(i) Let A = {2, 3, 4, 5} and B = {3, 6}

    Now A∩B

    = {2, 3, 4, 5} ∩ {3, 6} = {3}

    Hence, A and B are not disjoint. So the statement is false.

(ii) Let A = {a, e, i, o, u} and B = {a, b, c, d}

    Now A∩B

    = {a, e, i, o, u} ∩ {a, b, c, d}= {a}

    Hence, A and B are not disjoint. So the statement is false.

(iii) Let A = {2, 6, 10, 14} and B = {3, 7, 11, 15}

     Now, A∩B

     = {2, 6, 10, 14} ∩ {3, 7, 11, 15} = Φ

     Hence, A and B are disjoint sets. So the statement is true.

(iv) Let A = {2, 6, 10} and B = {3, 7, 11}

     Now A∩B  

     = {2, 6, 10} ∩ {3, 7, 11} = Φ

     Hence, A and B are disjoint sets. So the statement is true.

The conversion of 29 Celsius to Fahrenheit is 84.2.

Celsius and Fahrenheit are two common units of temperature measurement.

Celsius, also known as centigrade, is a temperature scale used in the metric system. It is defined by setting the freezing point of water at 0 degrees Celsius and the boiling point of water at 100 degrees Celsius at standard atmospheric pressure.

To convert 29 Celsius to Fahrenheit, you can use the following formula,

°F = (°C × 9/5) + 32

Plugging in the value of 29 Celsius, we get,

°F = (29 × 9/5) + 32

°F = (261/5) + 32

°F = 52.2 + 32

°F = 84.2

Therefore, 29 Celsius is equivalent to 84.2 Fahrenheit.

Correct Question :

What is the conversion of 29 Celsius to Fahrenheit ?

Answer:

The context that could not be modeled by an exponential function is "A car depreciates at a rate of 3.7% per year." Exponential functions are typically used to model situations involving growth or decay that occur at a constant rate over time. In this case, the rate of depreciation of the car is decreasing over time, so it cannot be modeled by an exponential function. A linear function or a more complex model may be more appropriate.

A transformation is applied to a figure to create a new figure, the transformation does not preserve congruence is option C, A dilation by a scale factor of 5.

An isometry is a transformation that retains congruence. In other words, a transformation in which the side lengths and angle measurements of the Image and Pre-Image are the same. Isometries include translations, reflections, and rotations. A translation is a "direct isometry" since it not only maintains congruence but also, unlike reflections and rotations, maintains orientation.

A dilation, on the other hand, is not an isometry since its Image is not consistent with its Pre-Image.

A transformation composition indicates that two or more transformations will be executed on the same item. On the same point, for example, we may do a reflection and then a translation.

Answer: L=22, W=9

Step-by-step explanation:

The length of a rectangular poster is 4 more inches than two times its width. The area of the poster is 198 square inches. Solve for the dimensions (length and width) of the poster.

L=4+2W [Length] (1)

W=W [Width] (2)

P=2L+2W [perimeter] (3)

A=L*W = 198[area](4)

Subing (1) and (2) into (3) and (4)

P=2(4+2W)+2W

A=W(4+2W)

Simplify

P=8+4W+2W=8+6W

A=4W+2W^2=198

A=2W^2+4W-198

Set equal to 0 and solve for W

W=(-b+√(b^2-4ac))/2a

W=(-b-√(b^2-4ac))/2a

W=(-4+√(4^2-4(2)(-198)))/(2(2)) = 9

W=(-4-√(4^2-4(2)(-198)))/(2(2)) =-11

Disregard W =-11 since distance can’t be negative and keep W=9. Plug W=9 into Length equation (1)

L=4+2(9)=22

If you are trying to find the missing measures of a rectangle, you should know that all rectangles have four sides, and each side has a length.

In other words, if you have a rectangle, two of the angles must be 90 degrees, and the other two angles must also be 90 degrees. To find the missing measures of a rectangle, you need to use the properties of rectangles.

First, find the length of each side. The length of all sides of a rectangle should be the same. Then, calculate the area of the rectangle. You can do this by multiplying the length of one side with the length of the other side.

Finally, you can use the Pythagorean Theorem to find the missing measures.

The Pythagorean Theorem states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

The Bell Curve is a symmetrical curve that represents the probability distribution of a random variable.

The Bell Curve, also known as the normal distribution or Gaussian distribution, is a statistical concept used to describe the distribution of a set of data. The Bell Curve is a symmetrical curve that represents the probability distribution of a random variable.

The Bell Curve is often used to describe the distribution of scores on a test or exam. In this context, the Bell Curve is used to represent the distribution of scores across a population. The mean score (average score) is represented by the highest point on the curve, and the standard deviation is represented by the width of the curve.

In terms of percentages, the Bell Curve can be divided into different standard deviations, with each standard deviation representing a certain percentage of the population. The percentages of the population within each standard deviation are as follows:

68.27% of the population falls within one standard deviation of the mean.

95.45% of the population falls within two standard deviations of the mean.

99.73% of the population falls within three standard deviations of the mean.

No, the probability be found by using the binomial probability formula with x counting the number who are left-handed. The correct option is (c) No, because the 100 adults were selected without replacement, the selections are dependent.

The binomial distribution assumes that the trials are independent, meaning that the outcome of one trial does not affect the outcome of any other trial. However, in this case, the 100 adults were selected without replacement, which means that the outcome of one selection affects the probability of the next selection. Therefore, the trials are dependent, and the binomial probability formula cannot be used.

Instead, we can use the hypergeometric distribution to calculate the probability of at least 30 left-handed adults in a sample of 100 adults selected without replacement from the U.S. population. The hypergeometric distribution takes into account the fact that the selections are dependent and is appropriate for this type of problem.

Answer:

The surface area of the triangular prism is 180 square centimeters.

Step-by-step explanation:

To find the surface area of a triangular prism, we need to find the area of each face and add them up. Let's call the base of the triangle b, the height of the triangle h, and the height of the prism (the distance between the two triangular faces) H.

The triangular faces each have an area of (1/2)bh, so the total area of the two triangular faces is bh. The rectangular faces each have an area of Hb, so the total area of the two rectangular faces is 2Hb. Finally, the top and bottom faces each have an area of b^2, so the total area of these two faces is 2b^2.

Adding all of these areas together, we get:

Surface area = bh + 2Hb + 2b^2

Substituting the given values, we get:

Surface area = (6 cm)(8 cm) + 2(5 cm)(6 cm) + 2(6 cm)^2

Surface area = 48 cm^2 + 60 cm^2 + 72 cm^2

Surface area = 180 cm^2

Therefore, the surface area of the triangular prism is 180 square centimeters.
