Therefore, the length of the side x is approximately 10.76.

A right-angled triangle, also known as a right triangle, is a type of triangle that has one of its angles measuring exactly 90 degrees. The other two angles in a right triangle are acute angles, which means they are less than 90 degrees. The side opposite to the right angle is called the hypotenuse, and it is the longest side of the triangle. The other two sides of the right triangle are called legs, and they are adjacent to the right angle. The Pythagorean theorem, which states that the sum of the squares of the lengths of the legs of a right triangle is equal to the square of the length of its hypotenuse, is a fundamental concept in the study of right triangles. Right triangles have many practical applications in geometry, trigonometry, and physics.

In a right triangle, the sum of the measures of the two acute angles is always 90 degrees. Therefore, the third angle in this triangle is:

90 - 34 = 56 degrees

Now, we can use the trigonometric ratios to find the length of the side x.

We know that the tangent of an angle is equal to the length of the opposite side divided by the length of the adjacent side. Therefore:

[tex]tan(34) = x/18[/tex]

To solve for x, we can multiply both sides by 18:

[tex]18 tan(34) = x[/tex]

Using a calculator, we can find that:

18 tan (34) ≈ 10.76.

The possible length, width, and perimeter for Small cage's floor is 4 feet, 3 feet and 14 feet respectively; for Medium cage's floor is 12 feet, 2 feet and 28 feet respectively and for Large cage's floor is 18 feet, 2 feet and 40 feet respectively.

What is perimeter?

Whether it be a two-dimensional shape or a one-dimensional length, a perimeter is a closed path that contains, surrounds, or delineates it.

We are given the floor areas of each cage.

For Small cage:

Area is given as 12 square feet which is a product of length and width.

So, here length can be 4 feet and width can be 3 feet.

Now, we get the perimeter as

⇒ Perimeter = 2 * (Length + width)

⇒ Perimeter = 2 * (4 + 3)

⇒ Perimeter = 2 * 7

⇒ Perimeter = 14 feet

For Medium cage:

Area is given as 24 square feet which is a product of length and width.

So, here length can be 12 feet and width can be 2 feet.

Now, we get the perimeter as

⇒ Perimeter = 2 * (12 + 2)

⇒ Perimeter = 2 * (14)

⇒ Perimeter = 28 feet

For Large cage:

Area is given as 36 square feet which is a product of length and width.

So, here length can be 18 feet and width can be 2 feet.

Now, we get the perimeter as

⇒ Perimeter = 2 * (18 + 2)

⇒ Perimeter = 2 * (20)

⇒ Perimeter = 40 feet

Hence, the required solution has been obtained but there are many other combinations possible.

Answer:

The total amount of money collected from selling tickets is: 1900 tickets × $4/ticket = $7,600 Since the cash prize is $3,800, the expected value can be calculated as follows: Expected value = (Probability of winning) × (Cash prize) + (Probability of losing) × (Cost of ticket) The probability of winning is 1 out of 1900 tickets sold, or 1/1900. The probability of losing is 1899/1900. So, the expected value is: (1/1900) × $3,800 + (1899/1900) × $4 = $1.999 Rounding to the nearest cent, the expected value is $2.00.

The correct answer is: The theoretical probability, P(blue), is 25%, and the experimental probability is 30%

Theoretical probability is a concept in mathematics and statistics that refers to the likelihood or chance of an event occurring based on mathematical reasoning and analysis. Theoretical probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes in a given situation or experiment. It is based on the assumption that each outcome is equally likely to occur.

The theoretical probability of pulling a blue marble from the bag is the number of blue marbles divided by the total number of marbles:

P(blue) = 10/40 = 1/4 = 25%

The experimental probability of pulling a blue marble from the bag is the number of times a blue marble was pulled divided by the total number of trials:

Experimental probability of pulling a blue marble = 12/40 = 3/10 = 30%

We can see that the experimental probability of pulling a blue marble is slightly higher than the theoretical probability, which is expected since this is based on a limited number of trials and chance variation can occur. However, as the number of trials increases, the experimental probability should converge to the theoretical probability.

The correct answer is: The theoretical probability, P(blue), is 25%, and the experimental probability is 30%.

The proportion of company breadth between the widget's weight of [tex]0.13[/tex]and its weight of [tex]71[/tex]ounce is [tex]81.53[/tex].

Meaning of the word "company" A company is a collective of individuals. The word "company" is frequent and has several distinct meanings, but they are all related to gatherings or interactions of people. The most frequent usage of the term "company" is to describe a firm.

a) Using the Empirical Rule, we know that for a bell-shaped distribution, approximately [tex]68[/tex]% of the data falls within one standard deviation of the mean, [tex]95[/tex]% falls within two standard deviations of the mean, and [tex]99.7[/tex]% falls within three standard deviations of the mean. Therefore, for this problem, we can say:

[tex]95[/tex]% of the widget weights lie between [tex](59-2(6)) = 47[/tex] and [tex](59+2(6)) = 71[/tex] ounces.

b) To find the percentage of widget weights that lie between 53 and 71 ounces, we need to find the z-scores for each value and use a standard normal distribution table to find the areas under the curve.

The z-score for [tex]53[/tex] ounces is: [tex](53-59)/6 = -1.00[/tex]

The z-score for [tex]71[/tex] ounces is: [tex](71-59)/6 = 2.00[/tex]

Using a standard normal distribution table, we can find the area to the left of each z-score:

The area to the left of [tex]z = -1.00[/tex] is 0.1587

The area to the left of [tex]z = 2.00[/tex] is 0.9772

To find the percentage of widget weights between [tex]53[/tex] and [tex]71[/tex] ounces, we can subtract the area to the left of [tex]z = -1.00[/tex] from the area to the left of [tex]z = 2.00[/tex] and multiply by [tex]100[/tex]:

Percentage [tex]= (0.9772 - 0.1587) * 100 = 81.85[/tex]%

Therefore, approximately [tex]81.85[/tex]% of the widget weights lie between 53 and [tex]71[/tex] ounces.

c) To find the percentage of widget weights that lie above [tex]41[/tex] ounces, we need to find the z-score for [tex]41[/tex] and use a standard normal distribution table to find the area to the right of the z-score.

The z-score for 41 ounces is: [tex](41-59)/6 = -3.00[/tex]

Using a standard normal distribution table, we can find the area to the right of [tex]z = -3.00[/tex]:

The area to the right of [tex]z = -3.00[/tex] is [tex]0.0013[/tex]

To find the percentage of widget weights above [tex]41[/tex]ounces, we can multiply the area to the right of [tex]z = -3.00[/tex] by [tex]100[/tex]:

Percentage [tex]= 0.0013 * 100 = 0.13[/tex]%

Between the widget's weight of 0.13 and its weight in ounces, there is an 68 % company breadth.

Percentage is a way of expressing a quantity or value as a fraction of 100. It is denoted by the symbol %, which means "per cent" or "out of 100"

a) Using the Empirical Rule, we know that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% of the data falls within two standard deviations of mean, and approximately 99.7% of the data falls within three standard deviations of mean.

Since the mean weight of the widgets is 59 ounces and the standard deviation is 6 ounces, we can use the Empirical Rule to determine that:

Approximately 68% of the widget weights lie between 53 and 65 ounces (one standard deviation below and above the mean).

Approximately 95% of widget weights lie between 47 and 71 ounces.

Approximately 99.7% of widget weights lie between 41 and 77 ounces.

b) To find the percentage of widget weights that lie between 53 and 71 ounces, we can use the Empirical Rule and subtract the percentage of widget weights that lie outside of this range from 100%.

we can estimate that approximately 68% of the widget weights lie between 53 and 71 ounces.

Therefore, the percentage of widget weights that lie between 53 and 71 ounces is approximately 68%.

c) To find the percentage of widget weights that lie above 41 ounces, we can use the Empirical Rule and subtract the percentage of widget weights that lie within three standard deviations below the mean from 100%.

Therefore, the percentage of widget weights that lie above 41 ounces is approximately:

100% - 99.7% = 0.3%

So, approximately 0.3% of the widget weights lie above 41 ounces.

The surface area of the composite figure is 944 cm².

What is the surface area of a cuboid?

Surface area of a cuboid is (lb+lh+bh) where l,b,h are length, breadth and height of the cuboid.

To find the surface area of the composite figure, we need to calculate the surface area of both cuboids and then subtract the area of any faces that are shared by both cuboids.

Given dimension of first cuboid is 14 cm × 8 cm × 2 cm and dimension of the second cuboid is 8 cm × 6 cm × 4 cm.

Surface area of the first cuboid:

Area of the top and bottom faces = 2(14 x 8) = 224 cm²

Area of the front and back faces = 2(14 x 2) = 28 cm²

Area of the left and right faces = 2(8 x 2) = 32 cm²

Total surface area of the first cuboid = 2(224) + 2(28) + 2(32) = 576 cm²

Surface area of the second cuboid:

Area of the top and bottom faces = 2(8 x 6) = 96 cm²

Area of the front and back faces = 2(8 x 4) = 64 cm²

Area of the left and right faces = 2(6 x 4) = 48 cm²

Total surface area of the second cuboid = 2(96) + 2(64) + 2(48) = 416 cm²

Now we need to identify the faces that are shared by both cuboids. The first cuboid has a bottom face that is the same size as the top face of the second cuboid (6 x 4). The surface area of this shared face is 48 cm².

Therefore, the surface area of the composite figure is total surface area of the first cuboid + Total surface area of the second cuboid - Area of shared face

= 576 + 416 - 48

= 944 cm²

So the surface area of the composite figure is 944 cm².

To solve the problem, we need to use the given function f(x) = 4 + z(0.25) where x is the amount of 25% orange juice drink added and z is the amount of 100% orange juice drink added.

We know that initially 4 gallons of pure juice are present. So, the total amount of juice in the mixture is 4 + x gallons.

When we add 2 gallons of 25% orange juice drink, x = 2 and z = 0. So, using the function f(x), we get:

f(2) = 4 + z(0.25)

    = 4 + 0(0.25)

    = 4

Therefore, the concentration of orange juice in the drink after adding 2 gallons of 25% orange juice drink is 4%, expressed as a percent but without the percent sign.

Answer: 4

Step-by-step explanation:

(f○g)(x) = f(g(x))

so, we use the expression of g(x) as the "x" in f(x).

(f○g)(x) = f(g(x)) = 3(x² + 3) - 1 = 3x² + 9 - 1 = 3x² + 8

so,

(f○g)(3) = 3×3² + 8 = 27 + 8 = 35

check :

g(3) = 3² + 3 = 9 + 3 = 12

f(g(3)) = f(12) = 3×12 - 1 = 36 - 1 = 35

correct.

The linear inequality for the shaded region with slope [tex]-4[/tex] is:

[tex]y < -4x+4[/tex]

In mathematics, a linear inequality is an inequality involving a linear function in one or more variables. It describes a region in the coordinate plane that satisfies the inequality.

In mathematics, the slope is a measure of the steepness of a line. It describes how much a line rises or falls as we move from left to right along it.

According to the given information

To write the linear inequality for the graph passing through points [tex](0,4)[/tex] and [tex](1,0)[/tex], we need to find the equation of the line first.

The slope of the line passing through these two points is:

[tex]m =(y_{2} -y_{1} )/(x_{2} -x_{1} )\\ = (0-4)/(1-0)\\ = -4[/tex]

Using the slope-intercept form of a linear equation, [tex]y = mx +b[/tex], where m is the slope and b is the y-intercept, we can find the equation of the line passing through these two points:

[tex]y = -4x+4[/tex]

Now, to write the linear inequality for this line, we need to determine which side of the line is shaded. We can use the test point [tex](0,0)[/tex] to check which side of the line contains the solutions to the inequality.

If we plug in [tex](0,0)[/tex] into the equation [tex]y = -4x+4[/tex], we get:

[tex]0= -4(0) +4\\0 = 4[/tex]

Since [tex]0[/tex] is not less than [tex]4[/tex], the point [tex](0,0)[/tex] is not a solution to the inequality. Therefore, we need to shade the side of the line that does not contain the origin [tex](0,0)[/tex].

The linear inequality for the shaded region is:

[tex]y < -4x +4[/tex]

Therefore any point below the line [tex]y < -4x +4[/tex] satisfies this inequality.

There are many tools available to calculate the line of best fit, including Excel, R, and Python. These tools provide the best equation that approximates the data

To determine which equation could be used as a line of best fit to approximate the data in a scatter plot, we need to look for the equation that closely follows the general trend of the data. The line of best fit is the straight line that best represents the data on the graph.

One common method for finding the line of best fit is through linear regression analysis. This involves calculating the slope and intercept of the line that best fits the data. The equation for a line is y = mx + b, where m is the slope and b is the y-intercept.

In general, the equation that could be used as a line of best fit depends on the data on the scatter plot. However, we can determine the best equation by looking at the trend of the data.
