Find M_ABD And MZCBD Given M ABC = 77. A (3x + 22) D 16 (5x - 17) B C MZ ABD | And MZCBD

Answers

Answer 1

Answer:

∠ ABD = 49°, ∠ CBD = 28°

Step-by-step explanation:

∠ ABD + ∠ CBD = ∠ ABC , substitute values

3x + 22 + 5x - 17 = 77 , that is

8x + 5 = 77 ( subtract 5 from both sides )

8x = 72 ( divide both sides by 8 )

x = 9

Thus

∠ ABD = 3x + 22 = 3(9) + 22 = 27 + 22 = 49°

∠ CBD = 5x - 17 = 5(9) - 17 = 45 - 17 = 28°

true or false. defects are additive in a multi-step manufacturing process.

Answers

The statement "defects are additive in a multi-step manufacturing process" is generally false.

It depends on the type of defects and the specific manufacturing process. In general, defects are not necessarily additive in a multi-step manufacturing process.

Some defects may be additive, meaning that they can accumulate or worsen as the manufacturing process progresses. For example, if a part is slightly out of tolerance in one step of the process, subsequent steps may exacerbate the deviation, leading to a larger defect in the final product.

On the other hand, some defects may be independent or even compensatory, meaning that they do not accumulate or cancel each other out as the process progresses. For example, if one step of the process introduces a defect in one dimension of a part, another step may correct the defect in another dimension, resulting in a final product that meets specifications.

Therefore, the statement "defects are additive in a multi-step manufacturing process" is generally false, as it depends on the specific types of defects and the manufacturing process being considered.

Find the surface area of the figure. Hint: the surface area from the missing prism inside the prism must be ADDED!

Answers

To find the surface area of the figure, we need to consider the individual surfaces and add them together.

First, let's identify the surfaces of the figure:

The lateral surface area of the larger prism (excluding the base)

The two bases of the larger prism

The lateral surface area of the smaller prism (excluding the base)

The two bases of the smaller prism

The lateral surface area of a prism is given by the formula: perimeter of the base multiplied by the height.

The bases of the prisms are rectangles, so their areas can be calculated by multiplying the length by the width.

To find the missing prism's surface area, we need to consider that it is a smaller prism nested inside the larger prism. The lateral surface area and bases of the missing prism should also be included.

Once we have calculated the individual surface areas, we add them together to find the total surface area of the figure.

Answers

The total cost incurred per month for renting apartment 3 is $2,150 and the apartment with the highest total cost per month is apartment 4, so the answer is 4.

How to determine costs?

To find the total cost incurred per month if Ryan rents apartment 3, we need to calculate the monthly rent and the commuting cost:

Monthly rent for apartment 3 = $2,000

Commuting cost for apartment 3 = 10 hours/month × $15/hour = $150

Total cost incurred per month for apartment 3 = $2,000 + $150 = $2,150

Therefore, the answer is C) $2,150.

To find the apartment that has the highest total cost per month, we need to calculate the total cost for each apartment by adding the monthly rent and commuting cost:

Apartment 1: $1,500 + 40 hours/month × $15/hour = $2,100

Apartment 2: $1,750 + 20 hours/month × $15/hour = $2,050

Apartment 3: $2,000 + 10 hours/month × $15/hour = $2,150

Apartment 4: $2,210 + 4 hours/month × $15/hour = $2,270

Apartment 5: $2,250 + 1 hour/month × $15/hour = $2,265

Therefore, the apartment with the highest total cost per month is apartment 4, so the answer is C) 4.

find the angle between the vectors. (first find an exact expression and then approximate to the nearest degree.) a = i 2j − 2k, b = 4i − 3k

Answers

The angle between the vectors a and b is approximately 48 degrees.

To find the angle between two vectors a and b, we can use the formula:

cos θ = (a · b) / (|a| |b|)

where a · b is the dot product of a and b, and |a| and |b| are the magnitudes of a and b, respectively.

First, let's find the dot product of a and b:

a · b = (i)(4) + (2j)(0) + (-2k)(-3) = 4 + 6 = 10

Next, let's find the magnitudes of a and b:

|a| = √(1^2 + 2^2 + (-2)^2) = √9 = 3

|b| = √(4^2 + 0^2 + (-3)^2) = √25 = 5

Substituting these values into the formula for cos θ, we get:

cos θ = 10 / (3 * 5) = 2/3

To find the angle θ, we can take the inverse cosine (cos^-1) of 2/3:

θ = cos^-1(2/3) = 48.19 degrees

Therefore, the angle between the vectors a and b is approximately 48 degrees.

true or false: if you are given a graph with two shiftable lines, the correct answer will always require you to move both lines.

Answers

False. if you are given a graph with two shif table lines, the correct answer will always require you to move both lines.

In a graph with two shiftable lines, the correct answer may or may not require moving both lines. It depends on the specific scenario and the desired outcome or conditions that need to be met.

When working with shiftable lines, shifting refers to changing the position of the lines on the graph by adjusting their slope or intercept. The purpose of shifting the lines is often to satisfy certain criteria or align them with specific points or patterns on the graph.

In some cases, achieving the desired outcome may only require shifting one of the lines. This can happen when one line already aligns with the desired points or pattern, and the other line can remain fixed. Moving both lines may not be necessary or could result in an undesired configuration.

However, there are also situations where both lines need to be shifted to achieve the desired result. This can occur when the relationship between the lines or the positioning of the lines relative to the graph requires adjustments to both lines.

Ultimately, the key is to carefully analyze the graph, understand the relationship between the lines, and identify the specific criteria or conditions that need to be met. This analysis will guide the decision of whether one or both lines should be shifted to obtain the correct answer.

Answers

The probability of that the first 40 feet in a roll contain no flaws is ≈ .3012

What is probability ?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Calculation

Θ = μ = \(\frac{100 foot}{3 flaws}\)

a ) We assume that the length until the first flaw follows an exponential distribution.

Probability density function of exponential distribution:

f(x) = \(\frac{1}{Θ} e^{\frac{-x}{Θ} } = \frac{1}{100/3}e^{-x/(100/3)} = \frac{3}{100}e^{-3x/100}\)

The first 40 feet in a roll of 100 feet contain no flaws if the first flaw occurs after 40 feet.

The probability is the integral over the corresponding interval:

Design a situation where the probability of one event is 1/5 and another event is 1/10

Answers

We have designed a situation where the probability of one event (event A) is 1/5 and the probability of another event (event B) is 1/10.

How to quantify probability?

To quantify the probability of each event, we can define the following events:

Event A: selecting a unit of product A at random and finding that it is defective.Event B: selecting a unit of product B at random and finding that it is defective.

Then, the probability of event A is 1/5, since 1 in every 5 units of product A is defective. Similarly, the probability of event B is 1/10, since 1 in every 10 units of product B is defective.

Now, let's consider a scenario where the company receives an order for 100 units of products, with 60 units of product A and 40 units of product B. The company wants to determine the probability of the following events:

Event C: selecting a unit from the order at random and finding that it is defective.Event D: selecting a unit from the order at random and finding that it is not defective.

To calculate the probability of event C, we need to consider the probability of selecting a defective unit from product A and from product B, and the proportion of each product in the order. Since the order has 60 units of product A and 40 units of product B, the probability of selecting a unit of product A is 60/100 = 3/5, and the probability of selecting a unit of product B is 40/100 = 2/5.

Using the probabilities of event A and event B, we can calculate the probability of selecting a defective unit from product A or from product B as follows:

Probability of selecting a defective unit from product A: 1/5Probability of selecting a defective unit from product B: 1/10

Therefore, the probability of event C can be calculated as follows:

P(C) = P(A) * P(A in order) + P(B) * P(B in order)

= (1/5 * 3/5) + (1/10 * 2/5)

= 3/25

So the probability of selecting a defective unit from the order is 3/25.

To calculate the probability of event D, we can use the complement rule, which states that the probability of an event and its complement (i.e., the event not happening) add up to 1. Therefore, the probability of event D can be calculated as follows:

P(D) = 1 - P(C)

= 1 - 3/25

= 22/25

So the probability of selecting a unit from the order at random and finding that it is not defective is 22/25.

In summary, we have designed a situation where the probability of one event (event A) is 1/5 and the probability of another event (event B) is 1/10. We have also calculated the probability of two other events (event C and event D) in a scenario where a manufacturing company produces two types of products, with different probabilities of defects, and receives an order with a certain proportion of each product.

How many four-letter sequences are possible that use the letters b, r, j, w once each? sequences

Answers

There are 24 possible four-letter sequences using the letters b, r, j, and w once each.

To find out how many four-letter sequences are possible using the letters b, r, j, and w once each, we can use the formula for permutations of n objects taken r at a time, which is:

P(n,r) = n! / (n-r)!

In this case, n = 4 (since there are 4 letters to choose from) and r = 4 (since we want to choose all 4 letters). So we can plug in these values and simplify:

P(4,4) = 4! / (4-4)!
P(4,4) = 4! / 0!
P(4,4) = 4 x 3 x 2 x 1 / 1
P(4,4) = 24

Answers

The sampling variability can be reduced by increasing the sample size. Hence, it is essential to ensure that a large enough sample size is used to obtain reliable estimates of population parameters.

Parameter and statistic: Parameter is a value that describes the population, while statistic is a value that describes a sample.

Parameters are usually represented using Greek letters, while statistics are usually represented using Roman letters. In other words, a parameter is a population characteristic, whereas a statistic is a sample characteristic.

P and p hat: P represents the true proportion of a population with a particular attribute, while p hat represents the proportion of a sample with that attribute. P hat is an estimate of the true proportion p, which may differ from the actual proportion due to sampling error.

Sampling variability: Sampling variability is the variation in sample statistics that occurs from sample to sample. It is the result of the fact that different samples of the same size drawn from the same population will produce different estimates of the population parameter due to random sampling error. The sampling variability can be reduced by increasing the sample size. Hence, it is essential to ensure that a large enough sample size is used to obtain reliable estimates of population parameters.
