The area of the triangle is 98.48. To solve the given triangles, we need to use trigonometric ratios such as sine, cosine, and tangent. Here are the steps for each triangle:

Triangle 1:
Angle A = 30 degrees
Side B = 7
Angle C = 95 degrees

To find side A, we can use the sine ratio:
sin(A)/7 = sin(95)/B
sin(A) = 7(sin(95)/B)
A = sin^-1(7(sin(95)/B))
A = 12.37 degrees

To find side C, we can use the angle sum property:
A + B + C = 180
30 + 95 + C = 180
C = 55 degrees

Now we can find side A using the sine ratio again:
sin(A)/7 = sin(C)/B
sin(A) = 7(sin(C)/B)
A = sin^-1(7(sin(C)/B))
A = 12.37 degrees

Triangle 2:
Side a = 600
Side b = 10
Angle B = 20 degrees

To find angle A, we can use the law of sines:
sin(A)/a = sin(B)/b
sin(A) = (a/b)sin(B)
A = sin^-1((a/b)sin(B))
A = 86.63 degrees

To find angle C, we can use the angle sum property:
A + B + C = 180
86.63 + 20 + C = 180
C = 73.37 degrees

Now we can find the area of triangle I using the formula:
Area = (1/2)ab(sin(C))
Area = (1/2)(600)(10)(sin(10))
Area = 51.51 square units

Triangle 3:
Side a = 10
Angle A = 20 degrees
Side b = 20

To find angle B, we can use the law of sines:
sin(B)/b = sin(A)/a
sin(B) = (b/a)sin(A)
B = sin^-1((b/a)sin(A))
B = 41.81 degrees

To find angle C, we can use the angle sum property:
A + B + C = 180
20 + 41.81 + C = 180
C = 118.19 degrees

Now we can find the area of the triangle using the formula:
Area = (1/2) ab (sin(C))
Area = (1/2) (10) (sin (118.19))
Area = 98.48 square units

Increasing the number of training examples tends to decrease both bias and variance, while increasing the complexity of the hypothesis decreases bias but increases variance.

In a binary classification task, bias refers to the error introduced by making assumptions about the relationship between features and the target variable, while variance refers to the error caused by the model's sensitivity to fluctuations in the training data.

Scenario: Increase the number of training examples (m):

Increasing the number of training examples tends to decrease both bias and variance. With more data, the model can better capture the underlying patterns in the data, reducing bias. Additionally, the model becomes less reliant on specific instances, resulting in lower variance as it becomes more robust to variations in the training set.

Scenario: Increase the complexity of the hypothesis (✓):

Increasing the complexity of the hypothesis can lead to a decrease in bias but an increase in variance. A more complex hypothesis can better fit the training data, reducing bias. However, it also becomes more sensitive to noise and fluctuations, causing an increase in variance.

In conclusion, increasing the number of training examples tends to decrease both bias and variance, while increasing the complexity of the hypothesis decreases bias but increases variance.

The point (9, -7) is the only solution to the system of linear inequalities given.

To determine which point would be a solution to the system of linear inequalities, let's substitute the given points into the inequalities and see which point satisfies both inequalities.

The system of linear inequalities is:

y > -4x + 6

y > (1/3)x - 7

Let's test each given point:

For the point (9, -7):

Substituting the values into the inequalities:

-7 > -4(9) + 6

-7 > -36 + 6

-7 > -30 (True)

-7 > (1/3)(9) - 7

-7 > 3 - 7

-7 > -4 (True)

Since both inequalities are true for the point (9, -7), it is a solution to the system of linear inequalities.

For the point (-12, -2):

Substituting the values into the inequalities:

-2 > -4(-12) + 6

-2 > 48 + 6

-2 > 54 (False)

-2 > (1/3)(-12) - 7

-2 > -4 - 7

-2 > -11 (False)

Since both inequalities are false for the point (-12, -2), it is not a solution to the system of linear inequalities.

For the point (12, 1):

Substituting the values into the inequalities:

1 > -4(12) + 6

1 > -48 + 6

1 > -42 (True)

1 > (1/3)(12) - 7

1 > 4 - 7

1 > -3 (True)

Since both inequalities are true for the point (12, 1), it is a solution to the system of linear inequalities.

For the point (-12, -7):

Substituting the values into the inequalities:

-7 > -4(-12) + 6

-7 > 48 + 6

-7 > 54 (False)

-7 > (1/3)(-12) - 7

-7 > -4 - 7

-7 > -11 (True)

Since one inequality is true and the other is false for the point (-12, -7), it is not a solution to the system of linear inequalities.

In conclusion, the point (9, -7) is the only solution to the system of linear inequalities given.

If the utilization of an M/M/1 model is 0.6, the c of time there is at least one person in the system is 100%.

In an M/M/1 model, the utilization represents the ratio of the arrival rate (λ) to the service rate (μ). If the utilization is less than 1, it means that the arrival rate is lower than the service rate, and the system is not fully utilized. However, even with a utilization of 0.6, there will still be instances where there is at least one person in the system. This is because the arrival rate is not zero, indicating that customers are still arriving, albeit at a lower rate compared to the service rate. Therefore, the percentage of time with at least one person in the system would be 100%. If you are told that the utilization rate for an M/M/1 model is 0.8 and the average number of people in the system is 4, it is impossible to determine the average number of people in the queue without further information. The average number of people in the queue depends on factors such as the arrival rate and service rate, which are not provided in this scenario. The utilization rate alone and the average number of people in the system do not provide sufficient information to calculate the average number of people in the queue accurately. Therefore, it is impossible to determine the average number of people in the queue based solely on the given information.

Answer:

The angels are 60 degrees and 120 degrees

Step-by-step explanation:

The sum of two supplementary angels equal 180 degrees.

So, lets look at the ratio: 6:3

We then add 6 and 3 together which gives us 9.

Then you put it in this equation:

9x = 180

x= 20

- You are adding the two numbers and dividing the sum by 180 because the answer will tell us how much 1 would equal.

- In this case, we multiply 20 by 6 = 120 degrees

- Then we multiply 20 by 3 = 60 degrees.

(We can check our answer by: 120 + 60 = 180 degrees) :)

The inverse of the function f(x) = (2x-1)/(6-5x) is f^{-1}(x) = (x+1)/(2x-6). This means that when x is substituted into f^{-1}(x), the result is the same as when the result of f(x) is substituted into x.

The inverse of a function is found by swapping the x and y values in the original function and solving for y. For example, if the function f(x) is y = 2x-1 then the inverse of the function would be x = 2y-1. Because the inverse of a function is defined as f(x) = y and f^{-1}(x) = x, we can then substitute the original equation for y and solve for x.In the case of f(x) = (2x-1)/(6-5x), we can solve for the inverse function by swapping the x and y values and solving for y. This gives us 6-5x = 2y-1, which can be rearranged to give us y = (x+1)/(2x-6). This is the inverse of the original function and is written as f^{-1}(x) = (x+1)/(2x-6). This means that when x is substituted into f^{-1}(x), the result is the same as when the result of f(x) is substituted into x.

\(f^{-1}(x) = \frac{x+1}{2x-6}\)

For example, if we set x = 4, then:

\(f^{-1}(4) = \frac{4+1}{2\times 4-6} = \frac{5}{6}\)

At each iteration of a 10-fold cross-validation with a data set of 80 observations, 72 observations are used for training.

In a k-fold cross-validation, the data set is divided into k subsets or folds. Each fold is used as a validation set, and the remaining folds are used for training. The process is repeated k times, with each fold serving as the validation set once.

Given:

Number of observations in the data set = 80

Number of folds in cross-validation (k) = 10

To determine the number of observations used for training at each iteration, we need to calculate the size of each fold.

Number of observations in each fold = Total number of observations / Number of folds

Number of observations in each fold = 80 / 10

Number of observations in each fold = 8

Therefore, at each iteration of the 10-fold cross-validation, 8 observations are used for training.

However, we want to know the total number of observations used for training, so we need to multiply the number of observations in each fold by the number of folds minus one.

Total number of observations used for training = Number of observations in each fold * (Number of folds - 1)

Total number of observations used for training = 8 * (10 - 1)

Total number of observations used for training = 8 * 9

Total number of observations used for training = 72

In a 10-fold cross-validation with a data set of 80 observations, 72 observations are used for training at each iteration.

The total interest paid in the balloon loan is $7,150.

A balloon loan is a type of loan that has a large lump sum payment due at the end of the loan term. The lump sum payment is usually a substantial amount, and as a result, the monthly payments during the loan term are lower than a typical loan.

Here is how you can solve this problem:

Calculation of total interest

1: Use the formula: Interest = Principal × rate × time

Interest = $13,000 × 0.055 × 10

Interest = $7,150

2: Add the interest to the principal to find the total amount paid

Total amount paid = Principal + Interes

tTotal amount paid = $13,000 + $7,150

Total amount paid = $20,150

Answer:

14 weeks till he has $480

Step-by-step explanation:

He needs $480

He has $60

He has to earn the rest over the span of the next few weeks, which is $30 for an unknown number of weeks.

Let the unknown number be x in our equation

What he needs to buy the TV and Stereo system is $480 which is our total

The $60 dollars he received is a complete variable

hence we can say, 30x+60=480

This is our equation but it isn't simplified.

first, divide everything by 10(it is a common divisor)

3x+6=48

subtract 6 which is complete from the total

3x=42

Make x the subject and divide both sides by 3

x=14

so the unknown number of weeks is 14.

The probability that marksman will hits the target at most 13 times is  27.92%.

The number of successes ("x") is the probability mass function for such binomial distribution.

We are interested in the likelihood that the target will be struck exactly five times, therefore the desired number of successes is five (i.e., x = 13).

P(X = 13) =  ¹⁵C₁₃. (0.89)¹³ (0.11)²

P(X = 13) = 0.2792

(a)The moment generating function of X is Mx(t) = \((e^(6t) + e^(7t) + e^(8t) + e^(9t)).\)

(b)The moment generating function of X+Y is MX+Y(t)= [\((e^(6t) + e^(7t)\) + \(e^(8t) + e^(9t)\))] × [(\(e^(18t) + e^(19t\)) + \(e^(20t) + e^(21t\)) + \(e^(22t) + e^(23t)\) + e^(24t) + \(e^(25t) + e^(26t)\))]

The moment generating function (MGF) of a random variable can be determined by taking the expected value of the exponential function raised to the product of the variable and a parameter. For a uniformly distributed random variable, we use the probability mass function (PMF) to calculate the MGF. By applying the formula and summing the contributions from each value in the support of the uniform distribution, we can obtain the MGF of the variable.

(a) To find the moment generating function (MGF) of a uniformly distributed random variable, we can use the formula:

Mx(t) = E[e^(tX)]

Since X is uniformly distributed on the set {6, 7, 8, 9}, the probability mass function (PMF) is:

P(X = 6) = P(X = 7) = P(X = 8) = P(X = 9) = 1/4

Using this PMF, we can calculate the MGF:

Mx(t) = E[e^(Xt)] = (e^(6t) × P(X = 6)) + (e^(7t) ×P(X = 7)) + (e^(8t) ×P(X = 8)) + (e^(9t) ×P(X = 9))

= (e^(6t) ×1/4) + (e^(7t) ×1/4) + (e^(8t) × 1/4) + (e^(9t) × 1/4)

So, the moment generating function of X is Mx(t) =  (e^(6t) + e^(7t) + e^(8t) + e^(9t)).

(b) Since X and Y are independent, the MGF of the sum X + Y is the product of their respective MGFs:

MX+Y(t) = Mx(t)× My(t)

The moment generating function of Y can be found similarly. Since Y is uniformly distributed on the set {18, 19, 20, 21, 22, 23, 24, 25, 26}, with equal probabilities for each value, we have:

My(t) = (e^(18t) + e^(19t) + e^(20t) + e^(21t) + e^(22t) + e^(23t) + e^(24t) + e^(25t) + e^(26t))/9

Therefore, the moment generating function of X + Y is:

MX+Y(t) = Mx(t) × My(t) = [(e^(6t) + e^(7t) + e^(8t) + e^(9t))] × [(e^(18t) + e^(19t) + e^(20t) + e^(21t) + e^(22t) + e^(23t) + e^(24t) + e^(25t) + e^(26t))]

:Therefore,the moment generating function of X is Mx(t) =  (e^(6t) + e^(7t) + e^(8t) + e^(9t)) and the moment generating function of X+Y is MX+Y(t)= [(e^(6t) + e^(7t) + e^(8t) + e^(9t))] × [(e^(18t) + e^(19t) + e^(20t) + e^(21t) + e^(22t) + e^(23t) + e^(24t) + e^(25t) + e^(26t))]

Given the following information for John Barker's repair shop in Ontario, we are required to calculate the HST payable or refund for the first reporting period. The HST rate for Ontario is 13%.Amount Before HST Sales $150,000 Equipment purchased $96,000 Supplies purchased $83,000 Wages paid $19,000 Rent paid $17,000Let's calculate the total HST collected from sales:

Total HST collected from Sales= HST Rate x Amount before HST Sales

Total HST collected from Sales= 13% x $150,000

Total HST collected from Sales= $19,500

Let's calculate the total ITCs for John Barker's repair shop:Input tax credits (ITCs) are the HST that a business pays on purchases made for the business. ITCs reduce the amount of HST payable. ITCs = (HST paid on eligible business purchases) - (HST paid on non-eligible business purchases)For John Barker's repair shop, all purchases are for business purposes. Hence, the ITCs are the total HST paid on purchases.

Total HST paid on purchases= HST rate x (equipment purchased + supplies purchased)

Total HST paid on purchases= 13% x ($96,000 + $83,000)

Total HST paid on purchases= $19,790

Let's calculate the net HST payable or refund:

Net HST payable/refund = Total HST collected from sales - Total ITCs

Net HST payable/refund = $19,500 - $19,790Net HST payable/refund

= -$290 Since the Net HST payable/refund is negative,

it implies that John Barker's repair shop is eligible for an HST refund. Hence, the correct option is d) A refund of $5,980.
