The actual nominal rate of return is approximately 6.68%. None of the provided answer options exactly match this value, but the closest option is 6.77%.

To calculate the actual nominal rate of return, we use the Fisher equation:

Nominal Rate = (1 + Real Rate) * (1 + Inflation Rate) - 1

Given:

Real Rate = 3.87% (0.0387 as a decimal)

Inflation Rate = 2.75% (0.0275 as a decimal)

Now, let's plug in the values:

Nominal Rate = (1 + 0.0387) * (1 + 0.0275) - 1

Nominal Rate = 1.0387 * 1.0275 - 1

Nominal Rate = 1.0668 - 1

Nominal Rate = 0.0668 or 6.68% (rounded to two decimal places)

So, the actual nominal rate of return is approximately 6.68%. None of the provided answer options exactly match this value, but the closest option is 6.77%.

Example : 5 + 4 + 6 = 15

In addition we subtract smaller by the bigger no.

Example : 5 -4 = 1

In Multiplication we multiply two or more number to get output.

Example : 5 x 4 x 6 = 120

In division we divide smaller number by the big one to take output.

Example : 12 / 6 = 2

So , In question, \(50^{2} - 48^{2} =196\)

The final answer is
O ∂^2z/∂x^2 = 12x^2
O ∂^2z/∂x∂y = ∂^2z/∂y∂x = -3
O ∂^2z/∂y^2 = 54y

To find the second partial derivatives, we first need to find the first partial derivatives:

∂z/∂x = 4x^3 - 3y
∂z/∂y = -3x + 27y^2

Now, we can find the second partial derivative:

∂^2z/∂x^2 = 12x^2
∂^2z/∂y^2 = 54y
∂^2z/∂x∂y = ∂/∂x (∂z/∂y) = ∂/∂y (∂z/∂x) =  -3
∂^2z/∂y∂x = ∂/∂y (∂z/∂x) = ∂/∂x (∂z/∂y) = -3

We can observe that the second mixed partials (∂^2z/∂x∂y and ∂^2z/∂y∂x) are equal, which is expected since z has continuous second partial derivatives and satisfies the conditions for the equality of mixed partials (i.e., the partial derivatives are all continuous in some open region containing the point of interest).

Step-by-step explanation:

The largest image of the mascot that will fit on the Web page is 135 pixels wide and 90 pixels high.

A ratio displays the multiplicity of two numbers. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8.

The connection between the amounts of two or more items is defined by a ratio. The amounts of the same kind are compared using this method. It is considered to be in proportion when two or more ratios are equal.

Two ratios are said to be in proportion if they are the same. If the four elements are a, b, c, and d in that order, then a/b = c/d. Extremes are the elements a and d, whereas mean terms are b and c. The ratio shows that the product of averages and the product of extremes are equal.

The height in the web page for the mascot is 90 pixels

let the width be x pixels

Therefore,

\(\frac{90}{x} = \frac{400}{600}\)

⇒ 400*x = 90*600

The train will arrive at its final destination at 2:57 P.M. in the afternoon.

The total distance of the trip is 221 miles and the train travels at an average speed of 34 miles per hour. Using the formula:

time = distance / speed

We can calculate the total time it will take for the train to complete the journey without stopping at stations:

time = 221 / 34 = 6.5 hours

However, the train stops at each of ten stations for four minutes each, so the total time spent stopping is 10 x 4 = 40 minutes, or 0.67 hours. Therefore, the total time the journey will take, including the stops, is:

total time = 6.5 + 0.67 = 7.17 hours

The train departs at 7:30 A.M., so we can add 7.17 hours to this time to find the arrival time:

7:30 A.M. + 7.17 hours = 2:57 P.M.

Therefore, the train will arrive at its final destination at 2:57 P.M. in the afternoon.

The new pressure of the nitrogen gas after it is transferred to a 15.0 L container is 833.3 mmHg.

We are given that;

Capacity of nitrogen gas= 25L

Pressure= 500mmHg

Now,

To find the new pressure of the nitrogen gas, we need to use Boyle’s law, which states that the product of pressure and volume of a gas is constant at constant temperature 12. The formula for Boyle’s law is:

P1V1 = P2V2

where P1 and V1 are the initial pressure and volume of the gas, and P2 and V2 are the final pressure and volume of the gas.

We are also given the final volume of the gas as 15.0 L. We need to find the final pressure of the gas.

Plugging in these values into the formula, we get:

(500.0 mmHg)(25.0 L) = P2(15.0 L)

Solving for P2, we get:

P2 = (500.0 mmHg)(25.0 L) / (15.0 L) P2 = 833.3 mmHg

Therefore, by algebra the answer will be 833.3 mmHg.

The probability that a randomly selected home in Queens has 4 or more computers is 0.1 or 10%. The correct answer is (b) 0.10.

The given probability distribution table shows the probabilities of having 1, 2, or 3 computers in a randomly selected home in Queens. However, the probability of having 4 or more computers is not given in the table.

To find the probability of having 4 or more computers in a randomly selected home, we can use the complement rule. The complement rule states that the probability of an event happening is equal to 1 minus the probability of the event not happening. In this case, the event we are interested in is having 4 or more computers in a home, and the complement of this event is having 1, 2, or 3 computers in a home.

So, the probability of having 4 or more computers in a randomly selected home in Queens can be calculated as:

P(4 or more) = 1 - P(1 or 2 or 3)

P(1 or 2 or 3) = P(1) + P(2) + P(3) = 0.4 + 0.3 + 0.2 = 0.9

P(4 or more) = 1 - 0.9 = 0.1

Therefore, the probability that a randomly selected home in Queens has 4 or more computers is 0.1 or 10%. The correct answer is (b) 0.10.

68% of buyers paid between $21,000 and $23,000 for the car.The 68-95-99.7 Rule is a rule used to calculate the percentage of observations that fall within a given range of a normal distribution

The 68-95-99.7 Rule is a rule used to calculate the percentage of observations that fall within a given range of a normal distribution. The rule states that 68% of observations fall within one standard deviation of the mean, 95% of observations fall within two standard deviations of the mean, and 99.7% of observations fall within three standard deviations of the mean. In this case, the mean price paid is $23,000 and the standard deviation is $2000. Therefore, the range of prices between $21,000 and $23,000 is one standard deviation from the mean, and 68% of buyers paid between $21,000 and $23,000.Mathematically, this can be expressed as P(21,000<X<23,000) = P(μ- σ < X < μ + σ) = 0.68, where μ is the mean and σ is the standard deviation. By substituting the given values of μ and σ, this equation simplifies to P(21,000<X<23,000) = P(23,000 - 2000 < X < 23,000 + 2000) = 0.68. Therefore,68% of buyers paid between $21,000 and $23,000 for the car.

The required equation of the line is y = -x - 5 which passes through the points (2, -7).

A straight line's general equation is y = MX + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.

On the y-axis, this value c is referred to as the intercept.

So, we have:

2x + 2y = −12

Rewrite as:

2x + 2y = −12

2y = -2x - 12

y = -2x/2 - 12

y = -x - 12

Since parallel lines have the same slope, the equation we're seeking has the following form:

So, we now have: y = -x - a

Now, insert x = 2 and y = -7 in y = -x - a:

y = -x - a

-7 = -2 - a

-a = -5

a = 5

The equation of the line: y = -x - 5

Therefore, the required equation of the line is y = -x - 5 which passes through the points (2, -7).
