Answer:

Rosie is 10 years old

Step-by-step explanation:

A)

Rosie is x years old

Rosie's age (R) = x

R = x

Eva is 2 years older

Eva's age (E) = x + 2

E = x + 2

Jack is twice Rosie’s age

Jack's age (J) = 2x

J = 2x

B)

R + E + J = 42

x + (x + 2) + (2x) = 42

x + x + 2 + 2x = 42

4x + 2 = 42

4x = 42 - 2

4x = 40

\(x = \frac{40}{4} \\\\x = 10\)

Rosie is 10 years old

\(\measuredangle A\cong \measuredangle E\implies 112=16x\implies \cfrac{112}{16}=x\implies \boxed{7=x} \\\\[-0.35em] ~\dotfill\\\\ \overline{MS}\cong \overline{NR}\implies 41=3x+5y\implies 41=3(7)+5y\implies 41=21+5y \\\\\\ 20=5y\implies \cfrac{20}{5}=y\implies \boxed{4=y}\)

For the company to practice price discrimination, there should not be any resale of its product, is not true if a public utility company is considered a monopolist. This is because price discrimination involves charging different prices to different groups of customers based on their willingness to pay. Resale of the product can actually facilitate price discrimination as it allows different customers to buy the product at different prices and then resell it to others. The other options are true for a monopolist, such as having upward sloping demand and supply curves, charging a price higher than its marginal revenue, and determining profit maximizing quantity at the point where marginal revenue equals marginal cost.

Let's analyze each statement:

A. The company's demand curve and supply curve are upward sloping.
This statement is NOT true for a monopolist. A monopolist faces a downward sloping demand curve, which means that they can increase the quantity sold by lowering the price. The supply curve does not apply in the traditional sense for monopolists, as they have the power to set both the price and quantity produced.

B. Its price must be higher than its marginal revenue.
This statement is true for a monopolist. Under a monopoly, the price charged by the company is higher than its marginal revenue due to the downward-sloping demand curve.

C. For the company to practice price discrimination, there should not be any resale of its product.
This statement is true. In order for a monopolist to successfully engage in price discrimination, they must prevent the resale of their product, ensuring that consumers cannot undercut the monopolist's pricing strategy.

D. Its profit maximizing quantity is determined where its marginal revenue equals its marginal cost.
This statement is true. A monopolist maximizes its profit by producing the quantity where marginal revenue equals marginal cost, and then setting the price based on the demand curve at that quantity.

So, the statement that is NOT true for a public utility company considered as a monopolist is: A. The company's demand curve and supply curve are upward sloping.

The correct answer is D: Max (Peak Memory BW x Arithmetic Intensity, Peak Floating-Point Performance).

1a. C: 101 to calculate the speedup, we need to consider the computing load distribution among the processors. In this case, 10 processors carry 20% of the load, which means each of these processors handles 2% of the load. The remaining 90 processors share the rest of the load evenly, so each processor among these 90 handles (100% - 20%) / 90 = 0.8889% of the load.

The speedup can be calculated using Amdahl's Law, which states that the speedup is limited by the portion of the program that cannot be parallelized. In this case, the matrix subtraction is fully parallelizable, so the only portion that cannot be parallelized is the sum of the scalar variables.

The speedup formula is given by: Speedup = 1 / [(1 - p) + (p / n)], where p is the portion that can be parallelized and n is the number of processors.

In this case, p = 0.02 (for the 10 processors) and n = 100. Substituting these values into the formula, we get: Speedup = 1 / [(1 - 0.02) + (0.02 / 100)] = 1 / 0.99 = 1.0101.

Therefore, the correct answer is C: 101.

Answer: A = 80 cm B = 140 cm

Step-by-step explanation:

To determine the best scale for the length axis, we need to consider the range of values in the data set. The length values range from 82 cm to 129 cm, which is a range of 47 cm. We want to choose a scale that can show this range without making the graph too large or too small.A common approach is to choose a scale that includes the minimum and maximum values, plus some additional values in between. One possible scale for the length axis is:

A = 80 cm

B = 140 cm

This scale includes the minimum value of 82 cm and the maximum value of 129 cm, as well as some additional values on either side. This scale should allow us to create a scatter plot that shows the relationship between length and mass clearly.

Elena's yearly cash inflows from the project after the payback period is $15,000. A correct answer is an option (b).

The payback period is the time it takes for the project's cash inflows to equal the initial investment. In this case, the payback period is 6 years, meaning that after 6 years, Elena will have received enough cash inflows to recover her initial investment of $150,000.

Since the project pays Elena an even amount per year for 10 years, and the payback period is 6 years, she will receive cash inflows for an additional 4 years after the payback period. Therefore, to calculate Elena's yearly cash inflows, we divide the remaining cash inflows by the number of years remaining:

Remaining cash inflows = $150,000 (initial investment) - cash inflows received during the payback period

= $150,000 - ($15,000 x 6)

= $60,000

Yearly cash inflows = Remaining cash inflows/number of years remaining

= $60,000 / 4

= $15,000

Hence, B is the correct option.

1. The population parameter are we trying to build an interval estimate for is p2 - p1.

2. The sample estimate for this quantity is 5000.

3. The standard error for the original sample statistic is μ

4. The center of your bootstrap distribution is variability.

5.  The bootstrap distribution represents many possible values of the sample statistic

6. The 95% confidence interval for the population parameter is 2.5 percentile

The population parameter we are trying to estimate is the difference in proportions between Republicans and Democrats who think that the COVID-19 situation is getting better. We can represent this parameter as p1 - p2, where p1 is the proportion of Republicans who think the COVID-19 situation is getting better, and p2 is the proportion of Democrats who think the COVID-19 situation is getting better.

To calculate the sample estimate for this quantity, we need to collect data from a sample of Republicans and Democrats and calculate the difference in proportions who think the COVID-19 situation is getting better.

To build a bootstrap confidence interval, we first create a bootstrap distribution by resampling our original sample with replacement many times at least 5,000 times.

The center of our bootstrap distribution is the mean of the bootstrap samples, which is an estimate of the true population parameter. We can represent this center as the mean of our bootstrap distribution, denoted as μ.

The center of the bootstrap distribution is likely to be close to the sample estimate, but it may be slightly different due to the variability in the bootstrap samples.

To compute the 95% confidence interval, we need to find the range of values in our bootstrap distribution that contains 95% of the values. We can do this by finding the 2.5th percentile and the 97.5th percentile of the bootstrap distribution, which represent the lower and upper bounds of our confidence interval.

Step-by-step explanation:

Let's start by simplifying our light terms.

\(q = \frac{33 \times 10 {}^{9} }{11 \times 10 {}^{7} } \)

33 is divisible by 11 so i can simplify up and down by 11.

\(q = \frac{3 \times 10 {}^{9} }{1 \times 10 {}^{7} } \)

Now i have 10^9 in the numerator and 10^7 in the denominator. I can remove 10^7 from up and down to get;

\(q = \frac{3 \times 10 {}^{9 - 7} }{1 \times 10 {}^{7 - 7} } = \frac{3 \times 10 {}^{2} }{1 \times 10 {}^{0} } = \frac{3 \times 10 {}^{2} }{1 \times 1} \)

\(q = 3 \times 10 {}^{2} \)

R(x, y) = (x, -y)

Step-by-step explanation:

When we have a reflection across some line, the distance between the original point and the reflected point to the line is invariant.

For a reflection around the x-axis, the x-value is invariant, then the only value that can change is the y-value.

So if we have a point like (4, 7)

Which is at a distance of 7 units to the x-axis, the only other point that is also at a distance of 7 units to the x-axis that has the same x-value is (4, -7)

Here we already can see the rule.

If we have a point (x, y), the reflection across the x-axis gives us the point (x. -y)

Then we can write this reflection as a function in the next way:

R(x, y) = (x, -y)

This means that if the input is the point (x, y), the output is the point (x, -y)

Answer:

Sure, here are the answers to your questions:

a. The maximum value of f(x,y) is 674.

b. The point(s) where the function attains its maximum are (-6,3) and (6,3).

c. The minimum value of f(x,y) is -5.

d. The point(s) where the function attains its minimum are (0,0) and (-3,-1).

Here are the steps on how I got the answers:

First, we need to find the critical points of the function. This can be done by finding the points where the gradient is equal to zero.

The gradient of f(x,y) is given by the following vector:

∇f(x,y) = (4x - 4, 6y)

Setting this vector equal to zero, we get the following system of equations:

4x - 4 = 0

6y = 0

Solving this system of equations, we get the following critical points:

(-6,3)

(6,3)

Next, we need to evaluate the function at each critical point and at the boundary points of the domain.

The boundary points of the domain are given by the following points:

(-13,0)

(13,0)

(0,-13)

(0,13)

Evaluating the function at each of these points, we get the following values:

f(-13,0) = -674

f(13,0) = -674

f(0,-13) = -674

f(0,13) = -674

f(-6,3) = 674

f(6,3) = 674

f(0,0) = -5

f(-3,-1) = -5

Finally, we need to compare the values of the function at the critical points and at the boundary points to find the maximum and minimum values.

The maximum value of the function is 674, which is attained at the points (-6,3) and (6,3).

The minimum value of the function is -5, which is attained at the points (0,0) and (-3,-1)

On 180° rotation of ΔDEF, the new triangle - ΔD'E'F' is obtained with data points D'(2,-1), E'(-3,-2), and F'(-1,-5).

What is rotation?

The circular movement of an object about a centre is referred to as rotation. Different forms can be rotated by an angle about their central point. A rotation is a map in mathematics. The rotation group of a particular space refers to all rotations around a fixed point that form a group beneath a structure.

The coordinate points for ΔDEF is given.

The points are D(-2,1), E(3,2), and F(1,5)

When a shape with data points is rotated 180° clockwise or counter clockwise the formula for the data points changes.

This new formula is (x,y) → (-x,-y).

Apply this formula for ΔDEF.

D(-2,1) → [-(-2),-(1)] → D'(2,-1)

E(3,2) → [-(3),-(2)] → E'(-3,-2)

F(1,5) → [-(1),-(5)] → F'(-1,-5)

This forms a new triangle ΔD'E'F'.

The plot for the triangles are made.

Therefore, the new data points are obtained as D'(2,-1), E'(-3,-2), F'(-1,-5).
