The angle x subtended by the arc of the circle between the two tangents is 130 degrees.

In trigonometry, the tangent (often abbreviated as tan) is a mathematical function that describes the ratio of the length of the side opposite to an angle in a right-angled triangle to the length of the adjacent side.

The formula 50=180-x represents the fact that the angle between two tangents drawn to a circle from an external point is equal to the difference of the angles subtended by the tangents in the opposite segment of the circle.

Using this formula, we can solve for x as follows:

50 = 180 - x (given)

x = 180 - 50 (subtracting 50 from both sides)

x = 130 (simplifying)

Therefore, the angle x subtended by the arc of the circle between the two tangents is 130 degrees.

The probability of winning something from the Pepsi sales promotion with winning symbols under the caps of 10% of all Pepsi bottles in a six-pack is 46.9%.

The probability of winning something from the Pepsi sales promotion depends on the total number of bottles in the six-pack and the percentage of bottles with winning symbols under the caps.

Assuming that the six-pack contains six bottles, and 10% of all Pepsi bottles have winning symbols under the cap, the probability of winning something from the promotion can be calculated using the following formula:

Probability of winning = Number of bottles with winning symbols / Total number of bottles

Since 10% of all Pepsi bottles have winning symbols, the probability of finding a winning symbol under one bottle cap is 10%. Therefore, the probability of winning from a six-pack is the same as finding at least one winning bottle cap in six bottles.

To calculate the probability of winning, we can use the complement rule, which states that the probability of an event occurring is equal to one minus the probability of the event not occurring.

So, the probability of not winning from a single bottle is 1 - 0.1 = 0.9. The probability of not winning from all six bottles is 0.9^6 = 0.531. Therefore, the probability of winning something from a six-pack is 1 - 0.531 = 0.469 or 46.9%.

In conclusion, the probability of winning something from the Pepsi sales promotion with winning symbols under the caps of 10% of all Pepsi bottles in a six-pack is 46.9%. This means that nearly half of the customers who buy a six-pack are likely to win something from the promotion.

However, it is important to note that this probability may vary depending on the total number of bottles and the percentage of winning symbols used in the promotion.

Answer: To calculate the mean square treatment (MST), we need to have the sums of squares for treatment (SST) and the degrees of freedom for treatment (dfT).

Assuming that there are k treatment groups and a total of n observations, we can calculate SST and dfT as follows:

SST = Σ(xi - x_bar)^2 - Σ(yi - y_bar)^2 / n

where xi is the dried weight of plants for the i-th treatment group, x_bar is the mean dried weight of plants for all treatments combined, yi is the dried weight of plants for the control group, and y_bar is the mean dried weight of plants for the control group.

dfT = k - 1

Once we have calculated SST and dfT, we can find MST by dividing SST by dfT:

MST = SST / dfT

Note that SST is the sum of squares for treatment, which represents the variation in the response variable that is due to the different treatment conditions. MST represents the average amount of variation in the response variable that can be attributed to the treatment conditions.

Without knowing the specific values for the dried weight of plants, it is not possible to calculate SST and dfT, and therefore the MST.

Step-by-step explanation:

The answer is attached below. There isn't much explanation for this. You just translate the word problem into a mathematical inequality.

the answer to the problem is that one angle measures 19.1 degrees and its complementary angle measures 70.9 degrees.

How to solve the question?

Let's first define the problem. Complementary angles are two angles whose sum is 90 degrees. Let x be the measure of one of the angles, then the measure of its complementary angle is 90 - x. According to the problem, one angle measures 51.8 degrees less than its complementary angle, so we can write:

x = (90 - x) - 51.8

Simplifying this equation, we get:

2x = 90 - 51.8

2x = 38.2

x = 19.1

Therefore, one angle measures 19.1 degrees and its complementary angle measures 90 - 19.1 = 70.9 degrees.

We can check that these angles are indeed complementary by verifying that their sum is 90 degrees:

19.1 + 70.9 = 90

So the answer to the problem is that one angle measures 19.1 degrees and its complementary angle measures 70.9 degrees.

Step-by-step explanation:

To find the range of the length of pipe that the plumber can cut, we need to write an absolute value inequality that expresses the condition that the length of the pipe must be within 0.09 meters of the required length. Let's call the required length L.

The plumber can cut a pipe that is within 0.09 meters of the required length, so the length of the pipe must be between L - 0.09 and L + 0.09. We can express this as:

|3.36 - L| ≤ 0.09

To solve this inequality, we need to consider two cases: when 3.36 - L is positive and when it is negative.

Case 1: 3.36 - L ≥ 0

In this case, the absolute value of 3.36 - L is equal to 3.36 - L. So we can write:

3.36 - L ≤ 0.09

Solving for L, we get:

L ≥ 3.36 - 0.09

L ≥ 3.27

Therefore, if 3.36 - L is positive, the length of the pipe must be greater than or equal to 3.27 meters.

Case 2: 3.36 - L < 0

In this case, the absolute value of 3.36 - L is equal to -(3.36 - L), or L - 3.36. So we can write:

L - 3.36 ≤ 0.09

Solving for L, we get:

L ≤ 3.36 + 0.09

L ≤ 3.45

Therefore, if 3.36 - L is negative, the length of the pipe must be less than or equal to 3.45 meters.

Putting these two cases together, we get:

3.27 ≤ L ≤ 3.45

Therefore, the range of the length of pipe that the plumber can cut is between 3.27 meters and 3.45 meters.

Y = 3(-3) + 4 = -5 when x is equal to 3. Hence, the final set of negative x- and y-coordinates is (-3, -5).

A set of numbers known as coordinates describes a point or object's location in a given space or coordinate system. When representing a spot's location in a plane or three-dimensional space, coordinates are frequently expressed as x or triples in mathematics. Depending also on system being utilised, several values can be used to represent coordinates, although often, integers or real numbers are used to express them.

We can substitute negative values for x and solve for y to obtain three pairs of negative x and y coordinates that lie on the line y = 3x + 4.

With x = 1, y = 3(-1), plus 4, equals 1. Hence, one set of negative x and y coordinates is (-1, 1).

Y = 3(-2) + 4 = -2 when x is equal to 2. In light of this, another set of negative x- and y-coordinates is (-2, -2).

At a function x = 4 has a vertical asymptote and at y = -15 has a horizontal asymptote.

The general form of a function is x= a and y = b.

f(x) = (kx + m) / (x - a) + b

k and m are constants.

We require a factor of (x - 4) in the denominator to get a vertical asymptote at x = 4. It is necessary for the fraction to approach -15 when x approaches positive or negative infinity in order to obtain a horizontal asymptote at y = -15.

One potential function that meets these specifications is:

H(x) = 6/(x - 4) - 15 + k

where k is a constant that establishes the function's vertical shift (i.e., its value at x = 0).

By entering a point on the graph, such as the x-intercept (where y = 0), the value of k can be determined:

0 = 6/(x - 4) - 15 + k

15 - k = 6/(x - 4)

x - 4 = 6/(15 - k)

x = 6/(15 - k) + 4

We may enter this value of x into the original equation to find k since y = 0 at the x-intercept:

0 = 6/((6/(15 - k) + 4) - 4) - 15 + k

0 = 6/(6/(15 - k)) - 15 + k

0 = 15 - k - 15 + k

The x-intercept and asymptotes are unaffected by the value of k, and any value of k will result in a function with the same asymptotes. K does, however, have an impact on the function's vertical shift.

We can select a value for k and then search for a specific function that has the specified asymptotes.

For instance, if we select k = 0, we obtain:

H(x) = 6/(x - 4) - 15

This function has the same shape as the original function H(x) presented in the problem and asymptotes at x = 4 and y = -15, respectively.

It would take Rafael approximately 9.05 hours to run a 50-mile marathon in Washington D.C. at the same pace he ran the Boston Marathon.

What is distance?

Distance is the measure of how far apart two objects or locations are from each other. It is usually measured in units such as meters, kilometers, miles, or feet.

To solve this problem, we can use the concept of the average speed or pace, which is given by the formula:

pace = time / distance

where pace is the time it takes to cover one unit of distance (e.g., one mile), time is the time taken to cover the distance, and distance is the distance covered.

We can rearrange this formula to find the time it would take to cover a given distance at a given pace:

time = pace * distance

Using this formula, we can find the pace at which Rafael ran the Boston Marathon:

pace = time / distance

pace = 4.75 hours / 26.2 miles

pace = 0.181 hours/mile

Now we can use this pace to find the time it would take Rafael to run a 50-mile marathon:

time = pace * distance

time = 0.181 hours/mile * 50 miles

time = 9.05 hours

Therefore, it would take Rafael approximately 9.05 hours to run a 50-mile marathon in Washington D.C. at the same pace he ran the Boston Marathon.
