Answer:

$5.75

Step-by-step explanation:

price of the two hot dogs = 1.50 × 2 = $3

Then

The total payment = 3 + 2.75 = $5.75

The total cost of repayment over 5 years is $23,300.

A loan repayment refers to the act of paying back money previously borrowed from a lender.

To get total cost of repayment, we must principal amount, the interest rate and the duration of the loan.

The formula to get total cost of repayment is given by \(Total Cost of Repayment = Principal + Interest\)

Interest = Principal * Interest Rate * Time

Given:

Principal amount is $20,000

Interest rate is 3.3%

Duration is 5 years.

Interest = $20,000 * 0.033 * 5

Interest = $3,300

Total Cost of Repayment = Principal + Interest

= $20,000 + $3,300

= $23,300.

The power rule for logarithms states that logb(M^p) = p * logb(M). The logarithm of a number with an exponent is the product of the exponent and the logarithm of that number.

The power rule states that logb(M^p) = p * logb(M), where M, b, and p are positive real numbers.

To understand this rule, let's consider an example. Suppose we have log2(8^2). According to the power rule, this is equivalent to 2 * log2(8).

In this case, M is 8, b is 2, and p is 2. The power rule tells us that we can bring the exponent (p) down and multiply it with the logarithm of the base (b) raised to the number (M).

So, log2(8^2) can be simplified as 2 * log2(8), which is 2 * 3 = 6.

In general, the power rule allows us to simplify logarithmic expressions by bringing the exponent down and multiplying it with the logarithm of the base.

This rule is particularly useful when dealing with complex logarithmic expressions and simplifying them to a more manageable form.

The required coefficient of determination (R²) for the given sum of squares , SSR , and SSE  is equal to 0.875.

Total sum of squares = 200

Sum of squares due to regression SSR = 175

Sum of squares due to error SSE = 25

The coefficient of determination (R²) is given by the formula,

R² = 1 - (SSE / SST)

The total sum of squares (SST) is 200

and the sum of squares due to error (SSE) is 25,

we can substitute these values into the formula to calculate R².

⇒ R² = 1 - (25 / 200)

⇒ R² = 1 - 0.125

⇒ R² = 0.875

Therefore, the coefficient of determination (R²) is 0.875.

There are 22,100 possible combinations of three cards when drawn in succession without replacement from a standard deck of cards.

There are a total of 52 cards in a standard deck. For the first draw, there are 52 possible cards to choose from. However, for the second draw, there are only 51 possible cards left since one card has already been chosen. Similarly, for the third draw, there are only 50 possible cards left since two cards have already been chosen.

Therefore, the total number of possible combinations of three cards is: 52 x 51 x 50 = 132,600

To answer your question, we will use the concept of combinations. A standard deck of cards has 52 cards. Since you are drawing 3 cards in succession without replacement, we need to find the number of combinations of 52 cards taken 3 at a time. The formula for combinations is:

C(n, k) = n! / (k! * (n-k)!)

Here, n is the total number of items (52 cards), and k is the number of items chosen (3 cards).

C(52, 3) = 52! / (3! * (52-3)!)

C(52, 3) = 52! / (3! * 49!)

C(52, 3) = 22100

So, there are 22,100 possible combinations of three cards when drawn in succession without replacement from a standard deck of cards.

After the 6-for-1 stock split, the stock price will be $16.41 per share, assuming no market imperfections or tax effects.

A stock split is a process in which a company increases the number of shares outstanding while proportionally reducing the price per share. In this case, the company plans a 6-for-1 stock split, which means that for every existing share, shareholders will receive six new shares.

To determine the post-split stock price, we divide the original stock price by the split ratio. The original stock price is $98.48, and the split ratio is 6-for-1. Therefore, we calculate:

$98.48 / 6 = $16.41

Hence, after the 6-for-1 stock split, the stock price will be $16.41 per share. This means that each shareholder will now hold six times more shares, but the value of their investment remains the same.

It is important to note that in practice, market imperfections, investor sentiment, and other factors can influence the stock price after a split. However, assuming no market imperfections or tax effects, the calculated value of $16.41 represents the theoretical post-split stock price.

The learning rate in gradient descent determines the step size and should be not too small or too large, as it can cause the algorithm to converge slowly or overshoot the minimum; adjusting the value of the learning rate can fix the problem, but the optimal value depends on the problem and data set.

According to the given information:

When running gradient descent,

The learning rate α determines the step size taken in each iteration toward the optimal solution.

If α is too small, the algorithm will take small steps and will converge slowly, or may even get stuck in a local minimum.

If α is too large, the algorithm may overshoot the minimum and diverge, or bounce back and forth without converging.

In the scenario described, the learning rate α of 0.5 appears too large, causing J(θ) to increase over time.

This suggests that the algorithm is not converging and is overshooting the minimum.

To fix this,
The value of α can be adjusted by reducing it to a smaller value,

Such as 0.1 or 0.01.

This should allow the algorithm to take smaller steps towards the minimum and eventually converge to a lower value of J(θ).

The equation of the tangent line to the graph of y=g(x) at x=5 is y = 4x - 23.

To find an equation of the tangent line to the graph of y=g(x) at x=5, we need to use the point-slope form of a line:

y - y1 = m(x - x1)

where (x1, y1) is the given point on the line and m is the slope of the line.

Given that g(5) = -3 and g'(5) = 4, we know that the point (5, -3) is on the tangent line and the slope of the tangent line at x=5 is 4. Therefore, the equation of the tangent line is:

y - (-3) = 4(x - 5)

Simplifying this expression, we get:

y + 3 = 4x - 20

y = 4x - 23

Therefore, the equation of the tangent line to the graph of y=g(x) at x=5 is y = 4x - 23.

  We are asked to evaluate the integral ∫c x dz, where C is the curve defined by the equation x² + y² = 4 in the counter-clockwise direction in quadrant 1.

To evaluate the given integral, we need to parameterize the curve C and then calculate the line integral along that parameterization.The equation x² + y² = 4 represents a circle centered at the origin with radius 2. In quadrant 1, the curve C corresponds to the upper half of this circle. We can parameterize this curve by using the trigonometric functions.
Let's parameterize the curve C as x = 2cos(t) and y = 2sin(t), where t ranges from 0 to π/2 to cover the upper half of the circle in the counter-clockwise direction.
Differentiating these parameterizations with respect to t, we get dx/dt = -2sin(t) and dy/dt = 2cos(t).Now, we can substitute these values into the integral ∫c x dz. Since dz = dx + i dy, we have dz = (-2sin(t) + i2cos(t)) dt.
Substituring all the values into the integral, we get ∫c x dz = ∫₀^(π/2) (2cos(t))(-2sin(t) + i2cos(t)) dt.
Simplifying this expression and integrating with respect to t over the given range, we can evaluate the integral to obtain the final result.

Answer:

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. Since the line given in the question is parallel to y = 1/4x + 7, we know that the line has a slope of m = 1/4.

To find the equation of the line that passes through (4,-1), we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1).

Therefore, the equation of the line passing through (4,-1) and parallel to y = 1/4x + 7 is:

y - (-1) = 1/4(x - 4)

y + 1 = 1/4x + 1

This is the equation of a line passing through (4,-1) and parallel to y = 1/4x + 7.

Among the given options, (C) The maximum of the 9 measurements is less than the maximum of the 10 measurements must be true about the 9 measurements, excluding the outlier, when compared with the 10 measurements.

An outlier is defined as a measurement that significantly deviates from the other measurements in a data set.

In this case, one of the measurements among the 10 is identified as an outlier.

When comparing the remaining 9 measurements with the entire set of 10 measurements, the maximum value of the 9 measurements cannot exceed the maximum value of the 10 measurements because the outlier, by definition, exceeds the upper quartile or lower quartile by at least 1.5 times the interquartile range.

It is important to note that the median of the 9 measurements can be either greater than or less than the median of the 10 measurements, depending on the specific values of the measurements.

The presence of the outlier does not necessarily determine the relationship between the medians of the two sets.

Similarly, the standard deviation of the 9 measurements may or may not be less than the standard deviation of the 10 measurements.

The inclusion or exclusion of the outlier can have an impact on the standard deviation calculation, but it is not guaranteed to be lower or higher in either case.

The Fundamental Theorem of Algebra states that every non-constant single-variable polynomial with complex coefficients has at least one complex root. This theorem is important as it provides a way to prove the existence of solutions to polynomial equations and provides an analytical tool to find the exact location of the solutions.

This theorem is also known as the algebraic version of the Intermediate Value Theorem as it states that if a polynomial is continuous on a closed interval, then it must take on all values between its maximum and minimum.

The theorem can be easily proven by considering a single-variable polynomial of degree n and transforming it into a polynomial of degree n−1 with the same roots. By repeating this process, the polynomial can be reduced to a constant and hence, it must have at least one root.
