Answer: C

Step-by-step explanation:

First, find the y-intercept of the graph -> when x = 0

In this case, y-intercept is +4. Hence answer is C immediately.

To double confirm the answer, find the gradient.

Gradient of graph is (4-0)/(0-(-2)) = 4/2 = 2 (any two fixed points on the graph can be obtained)

Hence, equation of graph is y = 2x+4 (form y = mx+c, where m is the gradient and c is the y-intercept of the graph)

The exact length of the curve is given by the integral of √(dx/dt)^2 + (dy/dt)^2 from t = 0 to t = 3.

130 words: To find the exact length of the curve defined by x = 6 + 3t^2 and y = 4 + 2t^3, where t ranges from 0 to 3, we can use the formula for arc length. The arc length, denoted as L, is given by the integral of the square root of the sum of the squares of the derivatives of x and y with respect to t, integrated over the range of t.

L = ∫[0 to 3] √((dx/dt)^2 + (dy/dt)^2) dt

First, we find the derivatives:

dx/dt = 6t

dy/dt = 6t^2

Substituting these derivatives into the arc length integral, we have:

L = ∫[0 to 3] √((6t)^2 + (6t^2)^2) dt

L = ∫[0 to 3] √(36t^2 + 36t^4) dt

Simplifying the expression under the square root, we get:

L = ∫[0 to 3] √(36t^2(1 + t^2)) dt

L = ∫[0 to 3] 6t√(1 + t^2) dt

Evaluating this integral will give us the exact length of the curve.

Answer:

1 1/6

Step-by-step explanation:

You can convert 7/6 into a mixed number by subtracting 1 from the improper fraction, because 1= 6/6

7/6 -6/6= 1 1/6

Answer:

7/6 would be 1 1/6

Step-by-step explanation:

To make it a number in general turn into a decimal.

Therefore, the MLE of θ is θ = -(1/n) ∑ln(x_i). Therefore, θ is an unbiased estimator of θ.

(a) To find the maximum likelihood estimator (MLE) of θ, we first write the likelihood function as follows:

L(θ|x_1, x_2, ..., x_n) = ∏(i=1 to n) f(x_i; θ)

= ∏(i=1 to n) [(1/θ)x_i(1-θ)/θ]

= (1/θ^n) ∏(i=1 to n) x_i(1-θ)

Taking the natural logarithm of L(θ|x_1, x_2, ..., x_n), we have:

ln(L(θ|x_1, x_2, ..., x_n)) = -n ln(θ) + (1-θ) ∑ln(x_i)

To find the MLE of θ, we differentiate ln(L(θ|x_1, x_2, ..., x_n)) with respect to θ and set the derivative to zero:

d/dθ ln(L(θ|x_1, x_2, ..., x_n)) = -n/θ + ∑ln(x_i) = 0

Solving for θ, we get:

θ = -(1/n) ∑ln(x_i)

(b) To show that θ is an unbiased estimator of θ, we need to find its expected value:

E(θ) = E[-(1/n) ∑ln(x_i)]

= -(1/n) ∑E[ln(x_i)]

= -(1/n) ∑[∫0^1 ln(x_i) (1/θ)x_i(1-θ)/θ dx_i]

= -(1/n) ∑[∫0^1 (1/θ)ln(x_i)x_i(1-θ) d(x_i)]

= -(1/n) ∑[θ(-1/(θ^2))(1/2)ln(x_i)^2|0^1 + (1/θ)(1/2)x_i^2(1-θ)|0^1]

= -(1/n) ∑[(1/2θ)ln(x_i)^2 - (1/2θ)x_i^2(θ-1)]

= -(1/n) [(1/2θ)∑ln(x_i)^2 - (1/2θ)(θ-1)∑x_i^2]

Note that ∑ln(x_i)^2 and ∑x_i^2 are constants with respect to θ. Therefore, we have:

E(θ) = -(1/n) [(1/2θ)∑ln(x_i)^2 - (1/2θ)(θ-1)∑x_i^2]

= (1/2) - (1/2nθ)

Since E(θ) = θ, we have:

θ = (1/2) - (1/2nθ)

Solving for θ, we get:

θ = 1/(n+2)

The solution in two parts:

* **a)** 15,000 cars will be ticketed that day.

* **b)** 45,000 cars will be traveling at a speed between 70 and 90 km/hour.

* **c)** 50% of cars will be traveling at a speed of less than 75 km/hour.

* **d)** The probability that a car traveling at a speed of more than 120 km/hour is 0.1587.

The speed of cars is normally distributed with an average of 90 km/hour and a standard deviation of 10 km/hour. This means that 68% of cars will be traveling between 80 and 100 km/hour, 16% of cars will be traveling less than 80 km/hour, and 16% of cars will be traveling more than 100 km/hour.

**a)** The number of cars that will be ticketed that day is equal to the percentage of cars traveling more than 100 km/hour multiplied by the total number of cars. This is 16% * 150,000 cars = 15,000 cars.

**b)** The number of cars traveling at a speed between 70 and 90 km/hour is equal to the area under the normal distribution curve between 70 and 90 km/hour. This area is equal to 0.6826, which means that 45,000 cars will be traveling at this speed.

**c)** The percentage of cars traveling at a speed of less than 75 km/hour is equal to the area under the normal distribution curve below 75 km/hour. This area is equal to 0.50, which means that 50% of cars will be traveling at this speed.

**d)** The probability that a car traveling at a speed of more than 120 km/hour is equal to the area under the normal distribution curve above 120 km/hour. This area is equal to 0.1587, which means that there is a 15.87% chance that a car will be traveling at this speed.

$a^4 - 3a^2 + 9$ can be factorised as $(a^2 - 3)(a^2 + 3)$

To factor $a^4 - 3a^2 + 9$ as a product of two monic quadratics with integer coefficients, we can use the difference of squares factorization.

When an expression has the general form a²+2ab+b², then we can factor it as (a+b)². For example, x²+10x+25 can be factored as (x+5)². This method is based on the pattern (a+b)²=a²+2ab+b², which can be verified by expanding the parentheses in (a+b)(a+b).

$a^4 - 3a^2 + 9$ can be factored as $(a^2 - 3)(a^2 + 3)$

Notice that both factors are monic quadratics with integer coefficients.

Answer:

57/99

Step-by-step explanation:

let's set up an equation:

x = 0.5757...

set up a second equation so the numbers after the decimal places are equal

100x = 57.5757...

subtract

100x = 57.5757...

- x = 0.5757

99x = 57

divide by 99

x = 57/99

0.57 repeating can be expressed as the fraction 19/33 in simplest form.

We have,

Let x = 0.575757... (with 57 repeatings)

Multiplying x by 100,

100x = 57.575757...

Subtracting the original x from 100x,

100x - x = 57.575757... - 0.575757...

99x = 57

To obtain x, divide both sides by 99:

x = 57/99

Dividing both the numerator and denominator by 3,

x = (57/3) / (99/3)

x = 19/33

Therefore,

0.57 repeating can be expressed as the fraction 19/33 in simplest form.

The equation of a line perpendicular to y=4/24x that pass through the point (-8, -4) is -6x-4y=16 where x-intercept is -6 and y-intercept is -4.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables.

a. The price of the consol is approximately $133.33.

b. The new price of the consol would be $100. The price of the consol falls by 24.99% and the interest rate rises by 1%.

c. Your holding period return is approximately -49.99%.

a. The price of the consol can be calculated using the formula for the present value of a perpetuity:

Price = Annual Payment / Interest Rate

In this case, the annual payment is $4 and the interest rate is 3%. Substituting these values into the formula:

Price = $4 / 0.03 ≈ $133.33

Therefore, the price of the consol is approximately $133.33.

b. To calculate the new price of the consol if the interest rate rises to 4%, we use the same formula:

New Price = Annual Payment / New Interest Rate

Substituting the values, we get:

New Price = $4 / 0.04 = $100

The percentage change in the price of the consol can be calculated using the formula:

Percentage Change = (New Price - Old Price) / Old Price * 100

Substituting the values, we have:

Percentage Change in Price = ($100 - $133.33) / $133.33 * 100 ≈ -24.99%

The percentage change in the interest rate is simply the difference between the old and new interest rates:

Percentage Change in Interest Rate = (4% - 3%) = 1%

Comparing the two percentages, we can see that the price of the consol falls by approximately 24.99%, while the interest rate rises by 1%.

c. The holding period return can be calculated using the formula:

Holding Period Return = (Ending Value - Initial Value) / Initial Value * 100

The initial value is the purchase price of the consol, which is $133.33, and the ending value is the price of the consol after one year with an interest rate of 6%. Using the formula for the present value of a perpetuity, we can calculate the ending value:

Ending Value = Annual Payment / Interest Rate = $4 / 0.06 = $66.67

Substituting the values into the holding period return formula:

Holding Period Return = ($66.67 - $133.33) / $133.33 * 100 ≈ -49.99%

Therefore, the holding period return is approximately -49.99%.
