Which Of The Following Rational Functions Is Graphed Below

E(Y/n) = p. This result shows that Y/n is an unbiased estimator for p since its expected value is equal to the true value of the parameter p. As n gets large, the term 1/n approaches zero, and therefore, the variance V(Y/n) approaches zero as well.

a) To derive the expected value of Y/n, we can use the linearity of expectation. Since Y follows a binomial distribution with parameters n and p, we have:

E(Y/n) = E(Y) / n

The expected value of Y is given by:

E(Y) = np

Substituting this into the expression, we get:

E(Y/n) = np / n

Simplifying, we find:

E(Y/n) = p

This result shows that Y/n is an unbiased estimator for p since its expected value is equal to the true value of the parameter p.

b) To derive the variance of Y/n, we can use the properties of variance. Since Y follows a binomial distribution with parameters n and p, the variance of Y is given by:

V(Y) = np(1 - p)

Using the properties of variance, we have:

V(Y/n) = V(Y) / n²

Substituting the expression for V(Y), we get:

V(Y/n) = (np(1 - p)) / n²

Simplifying, we find:

V(Y/n) = (p(1 - p)) / n

As n gets large, the term 1/n approaches zero, and therefore, the variance V(Y/n) approaches zero as well. This means that as the sample size increases, the variability of the estimator Y/n decreases, indicating a more precise estimate of the true parameter p.

In conclusion, the expected value of Y/n is equal to the true value of the parameter p, making Y/n an unbiased estimator. Additionally, as the sample size increases, the variance of Y/n decreases, leading to a more precise estimate of the parameter p.

Answer:

x=3/4, x=0.75

Step-by-step explanation:

The function G(n) in terms of f(n) is G(n) = 2/π² (f(n) - f²(n)).

To find the function G(n) in terms of f(n) based on the given expression, we substitute f(n) into the formula for G(n):

G(n) = 2/π² (Sin nπ/2 - Sin² nπ/2)

Replacing Sin nπ/2 with f(n), we have:

G(n) = 2/π² (f(n) - Sin² nπ/2)

Since f(n) is defined as f(n) = Sin nπ/2, we can simplify further:

G(n) = 2/π² (Sin nπ/2 - Sin² nπ/2)

Now we can substitute f(n) = Sin nπ/2 into the equation:

G(n) = 2/π² (f(n) - f²(n))

Therefore, the function G(n) in terms of f(n) is G(n) = 2/π² (f(n) - f²(n)).

Answer:

  A.  64 miles per hour

Step-by-step explanation:

In a linear equation, the "unit rate" is generally the coefficient of the variable. The units of the unit rate depend on the definition of the relationship.

Here, the time t is in hours, so the "unit rate" will be <something> per hour. The answer choices suggest that the <something> is "miles". That is, the units of the equation are ...

  (miles/hour) × (hours) = miles

With numbers/variables, that is ...

  (64 miles/hour) × (t hours) = 384 miles

The unit rate is 64 miles per hour.

The image of the 2 mile markers is missing as well as the options and so i have attached them.

Answer:

> 1.5 hours = 105 miles/speed

> Speed = 105 miles/1.5 hours

> 105 miles = 1.5 hours × speed

Step-by-step explanation:

From the image attached, the distance of the first mile marker is given as 50 miles while the distance of the second mile marker is given as 155 miles.

Thus, difference in distance between the two markers; d = 155 - 50 = 105 miles

Also, we see that the time of first marker is 3 pm while the second marker is 4:30 pm.

Thus, difference in time = 4:30 - 3 = 1 hour 30 minutes or 1.5 hours.

We know that;

Speed = distance/time

Thus;

Speed = 105/1.5

Speed = 70 mph

Thus, the 3 equations that represent this situation from the options are;

> 1.5 hours = 105 miles/speed

> Speed = 105 miles/1.5 hours

> 105 miles = 1.5 hours × speed

Answer:

1.5 hours = 105 miles/speed

Speed = 105 miles/1.5 hours

105 miles = 1.5 hours × speed

Step-by-step explanation:

From the given function f(x) the value of expression f(f(81)) is equal to 3.

Let's see how to find the answer to the question:

Find (f0f)(81)

In the given question, we need to find the value of (f0f)(81). This notation means (f◦f)(81).

Given that f(x)= sqrt(x) and g(x) =\((x - 7)^2\).

We know that to find (f◦f)(x), we need to evaluate f(f(x)).

This means we need to first evaluate f(x), and then evaluate f(f(x)).

To find (f◦f)(81), we need to find f(f(81)).

Using the function f(x), we find f(81):

f(81) = sqrt(81) = 9

Now, we use the function f(x) again to find f(f(81)):

f(f(81)) = f(9)

= sqrt(9)

= 3

Thus, we have found that

(f◦f)(81) = f(f(81))

= 3

Hence, the value of (f0f)(81) is 3.

Therefore, the value of (f0f)(81) is 3.

Answer: Let's represent the value of car 1 as x. Then, the value of car 2 is 3/4 of x, and the value of car 3 is 4/5 of the value of car 2.

So, we can write the following equations:

x = (3/4) * y

y = (4/5) * z

Where y is the value of car 2, and z is the value of car 3.

Adding all the values, we have:

x + y + z = 1115900

We can substitute the values of y and z in terms of x:

x + (3/4) * x + (4/5) * (3/4) * x = 1115900

Simplifying the expression on the left side, we get:

7/4 * x = 1115900

Finally, dividing both sides by 7/4, we get:

x = 359900

So, the value of car 1 is $359900, the value of car 2 is (3/4) * x = (3/4) * 359900 = 269925, and the value of car 3 is (4/5) * (3/4) * x = (4/5) * (3/4) * 359900 = 213140.

Step-by-step explanation:

Answer: the value of car 1 is $467125, the value of car 2 is $623033.33, and the value of car 3 is $350937.5.

Step-by-step explanation:

Let's call the value of car 1 "x".

From the first ratio, we know that the value of car 2 is 4/3 times greater than the value of car 1, and the value of car 3 is 3/4 times greater than the value of car 1.

So, the value of car 2 is 4/3 * x, and the value of car 3 is 3/4 * x.

From the second ratio, we know that the value of car 2 is 8/5 times greater than the value of car 3.

So, the value of car 2 is 8/5 * (3/4 * x) = 6/5 * x.

The total value of all three cars is $1115900, so we can set up an equation to solve for x:

x + 4/3 * x + 3/4 * x = 1115900

Expanding and simplifying the right side:

x + 4/3 * x + 3/4 * x = 1115900

8/3 * x = 1115900

x = 1115900 * 3 / 8

x = 467125

So, the value of car 1 is $467125, the value of car 2 is $623033.33, and the value of car 3 is $350937.5.

I will base my answer on that assumption.

the area of a rhombus is

p×q/2

p, q being the diagonals.

so, all 4 sides are equally long (5 cm).

the angle(s) between the diagonals is (are) 90°.

opposing angles are equally sized (B = D, A = C), and they are split in half by the diagonals.

and always remember : the sum of all angles in a triangle is always 180°.

so,

b1 = b2 = d1 = 50°.

a1 = a2 = c1 = c2 = 180 - 90 - 50 = 40°.

law of cosine :

c² = a² + b² - 2ab×cos(C)

with c being the side opposite of angle C. a, b are the kthe 2 sides.

1. In the context of spacetime, the locus of points equidistant from the origin of a spacetime plane is a hyperbola.

In Euclidean space, the distance between two points is given by the Pythagorean theorem, which only considers spatial dimensions. However, in spacetime, the concept of distance is extended to include both spatial and temporal components. The spacetime distance, also known as the interval, is given by the Minkowski metric:

ds^2 = -c^2*dt^2 + dx^2 + dy^2 + dz^2,

where c is the speed of light, dt represents the temporal component, and dx, dy, dz represent the spatial components.

To determine the locus of points equidistant from the origin, we need to find the set of points where the spacetime interval from the origin is constant. Setting ds^2 equal to a constant value, say k^2, we have:

-c^2*dt^2 + dx^2 + dy^2 + dz^2 = k^2.

If we focus on a spacetime plane where dy = dz = 0, the equation simplifies to:

-c^2*dt^2 + dx^2 = k^2.

This equation represents a hyperbola in the spacetime plane. It differs from a circle in Euclidean space due to the presence of the negative sign in front of the temporal component, which introduces a difference in the geometry.

Therefore, the locus of points equidistant from the origin in a spacetime plane is a hyperbola.

(Note: The explanation provided assumes a flat spacetime geometry described by the Minkowski metric. In the case of a curved spacetime, such as that described by general relativity, the shape of the locus of equidistant points would be more complex and depend on the specific curvature of spacetime.)

A firm experiences increasing returns to scale if inputs are doubled and output more than doubles.

When the firm's output grows at a faster rate than the growth in inputs, increasing returns to scale result. In this case, the company experiences economies of scale, which makes it more effective as it grows its production.

The firm is able to boost productivity and efficiency as it expands its scale of operations if inputs are doubled and output more than doubles.

This can be ascribed to a number of things, including specialisation, labour division, the use of capital-intensive technology, discounts for bulk purchases, and spreading fixed costs over a higher output. Lower average costs per unit of output result in higher profitability and competitiveness for the company.

Step-by-step explanation:

Yes, we can write 2.797979... as the decimal expansion of an irrational number.

We can express this number in the form of a repeating decimal, which is of the form p/q, where p is a finite decimal and q is the number of repeating decimals.

Let x = 2.797979...

Multiplying both sides by 100 gives us:

100x = 279.797979...

Subtracting x from 100x, we get:

99x = 277

x = 277/99

This is a rational number because it can be expressed as a fraction of two integers.

However, we can express this number in terms of an irrational number by taking the square root of 3.

Let y = sqrt(3)

We can write y in terms of a continued fraction, which is an expression of the form:

a0 + 1/(a1 + 1/(a2 + 1/(a3 + ...)))

where a0, a1, a2, a3, ... are integers.

The continued fraction for sqrt(3) is:

sqrt(3) = [1; 1, 2, 1, 2, 1, 2, ...]

This means that:

sqrt(3) = 1 + 1/(1 + 1/(2 + 1/(1 + 1/(2 + 1/(1 + 1/(2 + ...))))))

We can approximate this expression to get a decimal expansion of sqrt(3):

sqrt(3) ≈ 1.73205080757...

If we multiply this by 1.61616161... (which is the repeating decimal expansion of 0.797979...), we get:

sqrt(3) * 1.61616161... = 2.7979594554...

This is very close to the original number 2.797979..., but it is not the same. Therefore, 2.797979... is not a decimal expansion of an irrational number.
