The measure of angle A in the triangle is 18°

The angles in the triangle are given as:

m∠A = (2x − 24)°, m∠B = (x + 8)°, m∠C = (4x + 49)°

The sum of angles in a triangle is 180

So, we have

m∠A + m∠B + m∠C = 180

Substitute the known values in the above equation

So, we have:

2x − 24 + x + 8 + 4x + 49 = 180

Evaluate the like terms

7x = 147

Divide both sides by 7

x = 21

Substitute x = 21 in m∠A = (2x − 24)°

m∠A = (2 * 21 − 24)°

Evaluate

m∠A = 18°

Hence, the measure of angle A in the triangle is 18°

The engineer should take a sample size of approximately 40 to be 95% confident of being in error by only 0.125 minutes.

To calculate the sample size for estimating the cycle time, the engineer can use the formula for continuous data:

E = (zα/2) * (σ / √n)

where:
E is the maximum allowable error (0.125 minutes),
zα/2 is the z-value for a 95% confidence level (which corresponds to a 0.025 alpha level),
σ is the standard deviation (0.4 minutes), and
n is the sample size (unknown).

Rearranging the formula, we have:

n = (zα/2)^2 * (σ^2 / E^2)

Plugging in the given values, we get:

n = (1.96)^2 * (0.4^2 / 0.125^2)

Simplifying the equation, we have:

n ≈ 3.8416 * (0.16 / 0.015625)

n ≈ 3.8416 * 10.24

n ≈ 39.494

Answer:

Step-by-step explanation:

reciprocal of 1/3 then cross multiply

Same age

See explanation below

Let the age of Jasmine = y

Multiplying Jasmine age by 3 and adding 6:

= (y × 3) + 6

= 3y + 6

Multiplyng the sum by 2:

2 × the sum = 2 × (3y + 6)

= 6y + 12

Let James age = z

Multiplying the age by 2 and adding 4:

James age × 2 = z × 2 = 2z

adding 4 = 2z + 4

Multiplying the sum y 3:

3 × the sum = 3 × (2z + 4)

= 6z + 12

Now since they are twins, they ae most likely same age

This means:

6y + 12 = 6z + 12

subtracting 12 from both sides:

6y = 6z

dividing both sides by 6:

y = z

Hence, Jasmine age is the same as James age

B) The expression for Jasmine = 2(3y + 6) = 6y + 12

The expression for James = 3(2z + 4) = 6z + 12

let the twin's age = 2, 3, 4, 5

when twin's age = 2

6y + 12 = 6(2) + 12 = 12 + 12 = 24

6z + 12 = 6(2) + 12 = 12 + 12 = 24

when twin's age = 3

6y + 12 = 6(3) + 12 = 18 + 12 = 30

6z + 12 = 6(3) + 12 = 18 + 12 = 30

when twin's age = 4

6y + 12 = 6(4) + 12 = 24 + 12 = 36

6z + 12 = 6(4) + 12 = 24 + 12 = 36

when twin's age = 5

6y + 12 = 6(5) + 12 = 30 + 12 = 42

6z + 12 = 6(5) + 12 = 30 + 12 = 42

Median is a better indication of a "typical” salary at this business.

Step-by-step explanation:

A distribution is known as to be skewed to the right, or positively skewed, when maximum of the data are collected on the left of the distribution curve or the histogram.

A distribution is said to be skewed to the left, or negatively skewed, if maximum of the data are collected on the right of the distribution curve or the histogram.

It is provided that at a small business many people make very modest salaries and a few make very large salaries.

If a histogram is formed for the salaries of this companies employees, then most of the data will be collected towards the left of the graph and very few will be towards the right.

That is, the histogram will have a longer tail towards the right of the curve.

Thus, the distribution of the salaries at a small business is negatively skewed.

For a skewed distribution median is the best measure of average or typical value.

So, median is a better indication of a "typical” salary at this business.

Average waiting time for FCFS: 8.75

Average waiting time for SJF: 4.75

To solve this scheduling problem using FCFS (First-Come, First-Served) and SJF (Shortest Job First) algorithms, let's go step by step:

Schedule order for FCFS:

The FCFS algorithm schedules processes based on their arrival time. So, the schedule order for FCFS is as follows:

Pl -> P2 -> P3 -> P4

Average waiting time for FCFS:

To compute the average waiting time for FCFS, we need to calculate the waiting time for each process and then take the average.

Process | Arrival Time | Running Time | Waiting Time

Pl | 0 | 3 | 0

P2 | 3 | 10 | 3

P3 | 4 | 6 | 13

P4 | 5 | 1 | 19

Average waiting time = (0 + 3 + 13 + 19) / 4 = 8.75

Therefore, the average waiting time for FCFS is 8.75.

Schedule order for SJF:

The SJF algorithm schedules processes based on their running time. The process with the shortest running time gets executed first. If multiple processes have the same running time, the process with the earliest arrival time is selected first. The schedule order for SJF is as follows:

Pl -> P4 -> P3 -> P2

Average waiting time for SJF:

To compute the average waiting time for SJF, we need to calculate the waiting time for each process and then take the average.

Process | Arrival Time | Running Time | Waiting Time

Pl | 0 | 3 | 0

P4 | 5 | 1 | 3

P3 | 4 | 6 | 6

P2 | 3 | 10 | 10

Average waiting time = (0 + 3 + 6 + 10) / 4 = 4.75

Therefore, the average waiting time for SJF is 4.75.

Answer: First, we need to find out how many gallons of water are in the pool. We can use the fact that 1 ounce of chlorine is added per 2,700 gallons of water.

Let's assume the pool contains 10,000 gallons of water.

Then, Mr. Smith would add 10,000 / 2,700 = 3.7 ounces of chlorine every other day.

In one week, Mr. Smith would add 3.7 * 7 / 2 = 13 ounces of chlorine.

In three weeks, he would add 3 * 13 = 39 ounces of chlorine.

Finally, we need to convert ounces to pounds, since 1 pound = 16 ounces.

Therefore, 39 ounces = 39 / 16 = 2.44 pounds of chlorine.

So, Mr. Smith will add 2.44 pounds of chlorine to the pool in 3 weeks.

The demand function for good X is Qx = m - 3Px + 2Py, where Qx is the quantity demanded of X, m is income, Px is the price of X, and Py is the price of a related good Y. The equation shows that the demand for X is inversely related to its price and directly related to the price of Y. Income, price of X, and price of Y collectively affect the overall demand for X.


The demand function for good X is given by Qx = m - 3Px + 2Py, where Qx represents the quantity demanded of good X, m is the income, Px is the price of good X, and Py is the price of a related good Y. In this equation, the income and prices are assumed to be positive.

To determine the demand for good X, we can analyze the equation. The coefficient -3 in front of Px indicates that the demand for good X is inversely related to its price. As the price of X increases, the quantity demanded of X decreases, assuming other factors remain constant. On the other hand, the coefficient 2 in front of Py indicates that the demand for good X is directly related to the price of the related good Y. If the price of Y increases, the quantity demanded of X also increases, assuming other factors remain constant.

Furthermore, the term (m - 3Px + 2Py) represents the overall effect of income, price of X, and price of Y on the quantity demanded of X. If income (m) increases, the quantity demanded of X increases. If the price of X (Px) increases, the quantity demanded of X decreases. If the price of Y (Py) increases, the quantity demanded of X increases.

The domain of all six trigonometric functions is all real numbers, and the range of the sine and cosine functions is between -1 and 1, while the range of the tangent, cosecant, secant, and cotangent functions is all real numbers except for certain values where the denominator is equal to zero.

Using the properties of the unit circle, we can define the six trigonometric functions (sine, cosine, tangent, cosecant, secant, and cotangent) based on the coordinates of points on the unit circle.

The domain of all six trigonometric functions is the set of all real numbers, since the input angle can take any value in radians or degrees.

The range of the sine and cosine functions is the set of all real numbers between -1 and 1, inclusive. This is because the y-coordinate (sine) and x-coordinate (cosine) of any point on the unit circle can range from -1 to 1.

The range of the tangent, cosecant, secant, and cotangent functions is the set of all real numbers except for values where the denominator (sine, cosine) is equal to zero. For example, the range of the tangent function is all real numbers except for the values of x where cos(x) = 0, which occur at multiples of pi/2.

So, in summary, the domain of all six trigonometric functions is all real numbers, and the range of the sine and cosine functions is between -1 and 1, while the range of the tangent, cosecant, secant, and cotangent functions is all real numbers except for certain values where the denominator is equal to zero.

Using properties of the unit circle, the domain and range of the six trigonometric functions are as follows:

1. Sine (sin): Domain is all real numbers, Range is [-1, 1].
2. Cosine (cos): Domain is all real numbers, Range is [-1, 1].
3. Tangent (tan): Domain is all real numbers except odd multiples of π/2, Range is all real numbers.
4. Cosecant (csc): Domain is all real numbers except integer multiples of π, Range is (-∞, -1] and [1, ∞).
5. Secant (sec): Domain is all real numbers except odd multiples of π/2, Range is (-∞, -1] and [1, ∞).
6. Cotangent (cot): Domain is all real numbers except integer multiples of π, Range is all real numbers.

Step-by-step explanation:

Let B(x,y).

So, the coordinates of B are (6,7).

Based on the given information, a hypothesis test was conducted at a significance level of 0.1. The resulting p-value is 0.044. To determine whether to reject or fail to reject the null hypothesis , we compare the p-value to the significance level.

In this case, the p-value (0.044) is smaller than the significance level (0.1). This means that the observed data is unlikely to occur under the assumption that the null hypothesis is true. As a result, we reject the null hypothesis.

Rejecting the null hypothesis indicates that there is evidence to support the alternative hypothesis. The alternative hypothesis typically represents the researcher's claim or the hypothesis they are trying to prove. In this context, rejecting the null hypothesis suggests that there is evidence to support the alternative hypothesis.

Therefore, the correct conclusion is that there is sufficient evidence to reject the null hypothesis and accept the alternative hypothesis. It implies that the observed data provides enough support to conclude that there is a significant relationship, effect, or difference, depending on the specific context of the hypothesis test.

It is important to note that rejecting the null hypothesis does not prove the alternative hypothesis to be true. It simply indicates that there is enough evidence to suggest that the alternative hypothesis is more likely than the null hypothesis. The conclusion should be interpreted in the context of the specific hypothesis being tested and the significance level chosen.

The given argument is invalid. It says that if one person has more gray hair in their beard than another person, then they have a higher percentage of gray hair in their beard.

The argument is invalid because it is possible for one person to have a higher percentage of gray hair in their beard but a lower number of gray hairs in total.One possible counterexample by model is:Suppose Plato has 200 hairs in his beard and 50 of them are gray. So, 1/4 of his hairs are gray. Now, let's suppose Aristotle has 400 hairs in his beard, and 300 of them are gray. So, 3/4 of his hairs are gray. Even though Plato has fewer gray hairs than Aristotle, his percentage of gray hairs is more significant (1/4) than Aristotle's (3/4).

Therefore, the given argument is invalid since Aristotle's beard contains more gray hairs in quantity, but Plato has a higher percentage of gray hair in his beard.
