Use th Fundamental Theorem of Calculus to evaluate H(2), where H'(x)=sin(x)ln(x) and H(1.5)=-4.

In this case, homework is measured in points out of 100 and finals are measured in points out of 100, so the units for both the slope and y-intercept are "points per point."

Using the formula for the slope of the regression line:

b = r(SD of Y / SD of X)

where r is the correlation coefficient between X and Y, SD is the standard deviation, X is the predictor variable (homework), and Y is the response variable (finals).

Plugging in the values given in the table:

b = 0.5(15/8) = 0.9375

To find the y-intercept, we use the formula:

a = mean of Y - b(mean of X)

a = 65 - 0.9375(78) = -15.375

Therefore, the regression equation for predicting finals from homework is:

Finals = 0.94(Homework) - 15.38

Note that the units for the slope and y-intercept are determined by the units of the variables. In this case, homework is measured in points out of 100 and finals are measured in points out of 100, so the units for both the slope and y-intercept are "points per point."

The balance in the account after 11 years with continuous compounding at a 2% interest rate will be approximately $498.40.

To find the balance in an account when $400 is deposited for 11 years at an interest rate of 2% compounded continuously, you'll need to use the formula for continuous compound interest:

A = P * e^(rt)

where:
- A is the final account balance
- P is the principal (initial deposit), which is $400
- e is the base of the natural logarithm (approximately 2.718)
- r is the interest rate, which is 2% or 0.02 in decimal form
- t is the time in years, which is 11 years

Now, plug in the values into the formula:

A = 400 * e^(0.02 * 11)

A ≈ 400 * e^0.22

To find the value of e^0.22, you can use a calculator with an exponent function:

e^0.22 ≈ 1.246

Now, multiply this value by the principal:

A ≈ 400 * 1.246

A ≈ 498.4

So, the balance in the account after 11 years with continuous compounding at a 2% interest rate will be approximately $498.40.

For a 20 question multiple choice test, where each question has four choices:

Expected score on the test is 5.

The probability of getting 10 or more questions correct is approximately 0.026 or 2.6%.

In this scenario, each question has four possible answers, and you are guessing randomly, which means that the probability of guessing a correct answer is 1/4, and the probability of guessing an incorrect answer is 3/4.

Expected Score:

The expected score is the sum of the probability of getting each possible score multiplied by the corresponding score. The possible scores range from 0 to 20. If you guess randomly, your score for each question is a Bernoulli random variable with p = 1/4. Therefore, the total score is a binomial random variable with n = 20 and p = 1/4. The expected value of a binomial random variable with parameters n and p is np. Therefore, your expected score is:

Expected Score = np = 20 * 1/4 = 5

So, on average, you can expect to get 5 questions right out of 20.

Probability of getting 10 or more questions correct:

The probability of getting exactly k questions correct out of n questions when guessing randomly is given by the binomial probability distribution:

P(X = k) = (n choose k) * p^k * (1-p)^(n-k)

where n is the number of trials, p is the probability of success, and X is the number of successes.

To calculate the probability of getting 10 or more questions correct, we need to sum the probabilities of getting 10, 11, ..., 20 questions correct:

P(X >= 10) = P(X=10) + P(X=11) + ... + P(X=20)

Using a binomial calculator or software, we can find that:

P(X >= 10) = 0.00000355 (approximately)

So, the probability of getting 10 or more questions correct when guessing randomly is extremely low, about 0.00000355 or 0.000355%.

The net electric field will point to the left, in the direction of E2.

To find the direction of the net electric field of two point charges at the origin, we need to consider the direction of the electric fields due to each charge and add them as vectors.

Assuming both charges are positive (or both negative), the electric field due to each charge points away from it. The magnitude of the electric field due to a point charge Q at a distance r from it is given by Coulomb's law:

E = kQ/r^2,

where k is the Coulomb constant (k = 9 × 10^9 N·m^2/C^2).

At x = 0, the electric field due to the charge at -1 cm (which we'll call Q1) points to the right and has a magnitude of:

E1 = kQ1/(-0.01)^2

At x = 0, the electric field due to the charge at 2 cm (which we'll call Q2) points to the left and has a magnitude of:

E2 = kQ2/(0.02)^2

To find the net electric field at x = 0, we need to add the electric fields due to each charge as vectors. Since the electric fields due to the two charges have equal magnitude, we can simply subtract them as vectors. The direction of the net electric field will be the direction of the resulting vector.

The vector subtraction of the two electric fields can be represented as:

E_net = E2 - E1

where the positive sign of E1 implies that its direction is opposite to E2.

Substituting  values of E1 and E2, we get:

E_net = k[(Q2/0.02^2) - (Q1/0.01^2)]

Since Q2 is farther from the origin than Q1, its electric field has a greater magnitude. Therefore, the net electric field will point to the left, in the direction of E2.

The service level is 6.6%, indicating the percentage of demand that can be met from current stock.

To calculate the service level, we need to use the service level formula, which is:

Service Level = (Demand During Lead Time + Safety Stock) / Average Demand

In this case, we are given the historical average demand, which is 6105 units with a standard deviation of 243. We are also given that the company currently has 6647 units in stock. We need to calculate the demand during the lead time and the safety stock.

Assuming the lead time is zero (i.e., we receive inventory instantly), the demand during the lead time is also zero. Therefore, the demand during lead time + safety stock = safety stock.

To calculate the safety stock, we can use the following formula:

Safety Stock = Z * Standard Deviation * Square Root of Lead Time

Where Z is the number of standard deviations from the mean that corresponds to the desired service level. For example, for a service level of 95%, Z is 1.645 (assuming a normal distribution).

Assuming a lead time of one day and a desired service level of 95%, we can calculate the safety stock as follows:

Safety Stock = 1.645 * 243 * sqrt(1) = 402.76

Substituting the values into the service level formula, we get:

Service Level = (0 + 402.76) / 6105 = 0.066 or 6.6%

Therefore, the service level is 6.6%.

a. The point where the tangent is horizontal is (-7, -32).

b. The points where the tangent is vertical are (5, -16) and (5, 16).

To find the points on the curve where the tangent is horizontal, we need to find where the derivative dy/dx equals zero.

First, we need to find dx/dt and dy/dt using the chain rule:

dx/dt = -2t

dy/dt = 3t² - 12

Then, we can find dy/dx:

dy/dx = dy/dt ÷ dx/dt = (3t² - 12) ÷ (-2t) = -(3/2)t + 6

To find where dy/dx equals zero, we set -(3/2)t + 6 = 0 and solve for t:

-(3/2)t + 6 = 0

-(3/2)t = -6

t = 4

Now that we have the value of t, we can find the corresponding value of x and y:

x = 9 - t²= -7

y = t³ - 12t = -32

So the point where the tangent is horizontal is (-7, -32).

To find the points on the curve where the tangent is vertical, we need to find where the derivative dx/dy equals zero.

First, we need to find dx/dt and dy/dt using the chain rule:

dx/dt = -2t

dy/dt = 3t² - 12

Then, we can find dx/dy:

dx/dy = dx/dt ÷ dy/dt = (-2t) ÷ (3t² - 12)

To find where dx/dy equals zero, we set the denominator equal to zero and solve for t:

3t² - 12 = 0

t² = 4

t = ±2

Now that we have the values of t, we can find the corresponding values of x and y:

When t = 2:

x = 9 - t² = 5

y = t³ - 12t = -16

When t = -2:

x = 9 - t² = 5

y = t³ - 12t = 16

So the points where the tangent is vertical are (5, -16) and (5, 16).

The Coefficient of Determination (R²) measures the proportion of variance in the dependent variable (SSE) that is explained by the independent variable (SST). It ranges from 0 to 1, where 1 indicates a perfect fit. To calculate R², we use the formula: R² = SSE/SST. Now, if R² is 0.86, it means that 86% of the variance in SSE is explained by SST. Therefore, the statement "For SSE = 10, SST=60, Coeff. of Determination is 0.86" is true, as it is consistent with the formula for R².

The Coefficient of Determination is a statistical measure that helps to determine the quality of a linear regression model. It tells us how well the model fits the data and how much of the variation in the dependent variable is explained by the independent variable. In other words, it measures the proportion of variability in the dependent variable that can be attributed to the independent variable.

The formula for calculating the Coefficient of Determination is R² = SSE/SST, where SSE (Sum of Squared Errors) is the sum of the squared differences between the actual and predicted values of the dependent variable, and SST (Total Sum of Squares) is the sum of the squared differences between the actual values and the mean value of the dependent variable.

In this case, we are given that SSE = 10, SST = 60, and the Coefficient of Determination is 0.86. Using the formula, we can calculate R² as follows:

R² = SSE/SST
R² = 10/60
R² = 0.1667

Therefore, the statement "For SSE = 10, SST=60, Coeff. of Determination is 0.86" is false. The correct value of R² is 0.1667.

The Coefficient of Determination is an important statistical measure that helps us to determine the quality of a linear regression model.

Answer: Let x be the cost of one slice of pizza and y be the cost of one soda.

From the problem, we know that:

6x + 4y = 37 ...(1)

4x + 6y = 33 ...(2)

To solve for x and y, we can use the method of elimination. Multiplying equation (1) by 3 and equation (2) by 2, we get:

18x + 12y = 111 ...(3)

8x + 12y = 66 ...(4)

Subtracting equation (4) from equation (3), we get:

10x = 45

Dividing both sides by 10, we get:

x = 4.50

Substituting this value of x into equation (1), we get:

6(4.50) + 4y = 37

Simplifying, we get:

27 + 4y = 37

Subtracting 27 from both sides, we get:

4y = 10

Dividing both sides by 4, we get:

y = 2.50

Therefore, one slice of pizza costs $4.50 and one soda costs $2.50.

To apply the law of large numbers (LLN) to the average of Z, we need to make the following assumptions:

The expected value E(Zi) exists and is finite for all i.

The LLN states that as the sample size n increases, the sample mean of the observations Z1, Z2, ..., Zn converges in probability to the expected value E(Zi):

lim (n → ∞) P(|(Z1 + Z2 + ... + Zn)/n - E(Zi)| > ε) = 0,

for any ε > 0.

The value of the iterated integral /4 0 5 0 y cos(x) dy dx is 12.25sin(4). This means that the integral represents the signed volume of the region bounded by the xy-plane

To evaluate the iterated integral /4 0 5 0 y cos(x) dy dx, we first need to integrate with respect to y, treating x as a constant. The antiderivative of y with respect to y is (1/2)y^2, so we have:

∫cos(x)y dy = (1/2)cos(x)y^2

Next, we evaluate this expression at the limits of integration for y, which are 0 and 5. This gives us:

(1/2)cos(x)(5)^2 - (1/2)cos(x)(0)^2
= (1/2)cos(x)(25 - 0)
= (1/2)cos(x)(25)

Now, we need to integrate this expression with respect to x, treating (1/2)cos(x)(25) as a constant. The antiderivative of cos(x) with respect to x is sin(x), so we have:

∫(1/2)cos(x)(25) dx = (1/2)(25)sin(x)

Finally, we evaluate this expression at the limits of integration for x, which are 0 and 4. This gives us:

(1/2)(25)sin(4) - (1/2)(25)sin(0)
= (1/2)(25)sin(4)
= 12.25sin(4)

Therefore, the value of the iterated integral /4 0 5 0 y cos(x) dy dx is 12.25sin(4). This means that the integral represents the signed volume of the region bounded by the xy-plane, the curve y = 0, the curve y = 5, and the surface z = y cos(x) over the rectangular region R = [0,4] x [0,5].

The equilibrium quantity is 625.

The producer surplus at the equilibrium quantity is 234,125.

To find the equilibrium quantity, we need to find the value of x where demand equals supply.

Equating demand and supply:

d(x) = s(x)

500 - 0.2x = 0.6x

Simplifying and solving for x:

0.8x = 500

x = 625

To find the producer surplus at the equilibrium quantity, we first need to find the equilibrium price, which is the price at which the quantity demanded equals the quantity supplied.

Substituting x = 625 into either the demand or supply function, we get:

d(625) = 500 - 0.2(625) = 375

s(625) = 0.6(625) = 375

Therefore, the equilibrium price is 375.

The producer surplus at the equilibrium quantity is the area above the supply curve and below the equilibrium price. To find this area, we need to find the total revenue received by the producers and subtract their total variable costs.

Total revenue at the equilibrium quantity is:

TR = P x Q = 375 x 625 = 234,375

Total variable costs at the equilibrium quantity are:

TVC = 0.4 x Q = 0.4 x 625 = 250

Therefore, the producer surplus at the equilibrium quantity is:

PS = TR - TVC = 234,375 - 250 = 234,125

Combining like terms, we get:

500 = 0.8x

Dividing both sides by 0.8, we find:

x = 500 / 0.8 = 625

So the equilibrium quantity is 625.

To find the producer's surplus at the equilibrium quantity, we need to calculate the area between the supply curve and the market price.

The market price is determined by the demand and supply equations when they are equal. Plugging in the equilibrium quantity of x = 625 into either the demand or supply function will give us the market price.

Using the supply function, we have:

s(x) = 0.6x

s(625) = 0.6 * 625 = 375

So the market price is 375.

The producer's surplus is the area between the supply curve and the market price, up to the equilibrium quantity.

To calculate the producer's surplus, we can integrate the supply function from 0 to the equilibrium quantity of x = 625:

Producer's Surplus = ∫[0, 625] s(x) dx

= ∫[0, 625] 0.6x dx

= 0.6 * ∫[0, 625] x dx

= 0.6 * [(1/2) x²] |[0, 625]

= 0.6 * (1/2) * (625)²

= 0.6 * (1/2) * 390625

= 117187.5

So the producer's surplus at the equilibrium quantity is 117187.5 units.

The estimated flux of f out of the small sphere is approximately 0.000021.

To estimate the flux of the vector field f out of a small sphere centered at (3, 5, 6), we need to use the divergence theorem.

According to the divergence theorem, the flux of f across the surface S enclosing a volume V is equal to the triple integral of the divergence of f over V:

flux = ∫∫S f · dS = ∭V div f dV

Since the vector field f is smooth, its divergence is continuous and we can evaluate it at the center of the sphere:

div f(3, 5, 6) = 5

Therefore, the flux of f out of the sphere can be estimated as:

flux ≈ div f(3, 5, 6) [tex]\times[/tex]volume of sphere

flux ≈ 5 [tex]\times[/tex](4/3) [tex]\times[/tex]π [tex]\times[/tex](0.0[tex]1)^3[/tex]

The question is asking for an estimate of the flux of a smooth vector field out of a small sphere of radius 0.01 centered at a specific point. Flux refers to the flow of a vector field through a surface, in this case the surface of the sphere.

The given information, div f = 5 at the center of the sphere, is used to calculate the flux through the surface using the Divergence Theorem. The result is an estimate of the total amount of vector field flowing out of the sphere. The small radius of the sphere means that the estimate will likely be very small, as the vector field has less surface area to flow through. The final answer, .000021, is rounded to six decimal places.
To estimate the flux of the vector field f out of a small sphere centered at (3, 5, 6) with a radius of 0.01, you can use the divergence theorem. The divergence theorem states that the flux through a closed surface (in this case, a sphere) is equal to the integral of the divergence of the vector field over the volume enclosed by the surface.

Since the div f(3, 5, 6) = 5, you can assume that the divergence is constant throughout the sphere. The volume of a sphere is given by the formula V = (4/3)πr^3. With a radius of 0.01, the volume is:

V = (4/3)π(0.01)^3 ≈ 4.19 x 10^-6.

Now, multiply the volume by the divergence to find the flux:

Flux = 5 × (4.19 x 10^-6) ≈ 2.095 x 10^-5.

The required answer is the current in the second parallel wire is approximately 0.446 A.

we can determine the current in the second wire using Ampere's law. Here's a step-by-step explanation:

1. A vertical straight wire carries an upward 29-A current.
2. The force per unit length between the two wires is given as 8.3×10^-4 N/m.
3. The distance between the two parallel wires is 5.5 cm, which is equal to 0.055 m.
The attractive force per unit length of 8.3×10−4 n/m is exerted by the first vertical wire, which carries an upward 29-aa current, on the second parallel wire located 5.5 cm away.
We'll use Ampere's law to find the current in the second wire. The formula for the force per unit length between two parallel wires is:
F/L = (μ₀ × I₁ × I₂) / (2π × d)

where F is the force, L is the length of the wires, μ₀ is the permeability of free space (4π × 10^-7 T·m/A), I₁ and I₂ are the currents in the wires, and d is the distance between the wires.
Rearranging the formula to find I₂, we get:
I₂ = (2π × d × F/L) / (μ₀ × I₁)
Now, plug in the given values:
I₂ = (2π × 0.055 × 8.3 × 10^-4) / (4π × 10^-7 × 29)
I₂ ≈ 0.446 A

The probability that a puppy is picked from the pet store is 0.375 or 37.5%.

To determine the probability of picking a puppy from the pet store, we need to take into account the relative frequency of puppies compared to the other pets.

According to the problem statement, puppies are chosen twice as often as the other pets. Therefore, we can assign a weight of 2 to each puppy and a weight of 1 to each of the other pets.

This means that the total weight of all the puppies is 6 x 2 = 12, while the total weight of all the other pets is (9+4+7) x 1 = 20.

To calculate the probability of picking a puppy, we need to divide the weight of all the puppies by the total weight of all the pets:

Probability of picking a puppy = Weight of all the puppies / Total weight of all the pets

= 12 / (12+20)

= 12 / 32

= 3 / 8

= 0.375

Therefore, the probability of picking a puppy from the pet store is 0.375 or 37.5%.

It's important to note that this probability assumes that all the pets are equally likely to be chosen, except for the fact that puppies are chosen twice as often.

If there are any other factors that could influence the likelihood of picking a certain pet, such as their position in the store or their visibility, this probability may not accurately reflect the true likelihood of picking a puppy.

To show that if f is integrable on [a, b], then f is integrable on every interval [c, d] ⊆ [a, b], we need to use the definition of integrability.

Recall that a function f is integrable on an interval [a, b] if and only if for any given ε > 0, there exists a partition P of [a, b] such that the difference between the upper and lower Riemann sums of f over P is less than ε. That is,

|U(f, P) - L(f, P)| < ε,

where U(f, P) is the upper Riemann sum of f over P and L(f, P) is the lower Riemann sum of f over P.

Now, suppose f is integrable on [a, b]. We want to show that f is also integrable on every interval [c, d] ⊆ [a, b]. Let ε > 0 be given. Since f is integrable on [a, b], there exists a partition P of [a, b] such that

|U(f, P) - L(f, P)| < ε/2.

Now, since [c, d] ⊆ [a, b], we can refine the partition P to obtain a partition Q of [c, d] by only adding or removing points from P. More formally, we can define Q as follows:

Q = {x0 = c, x1, x2, ..., xn-1, xn = d},

where x1, x2, ..., xn-1 are points in P that are also in [c, d].

Then, we have

L(f, Q) ≤ L(f, P),

since L(f, Q) is computed using a smaller set of partitions than L(f, P).

Similarly,

U(f, Q) ≥ U(f, P),

since U(f, Q) is computed using a larger set of partitions than U(f, P).

Now, we can use the triangle inequality to get

|U(f, Q) - L(f, Q)| ≤ |U(f, Q) - U(f, P)| + |U(f, P) - L(f, P)| + |L(f, P) - L(f, Q)|.

By the definition of Q, we know that

|U(f, Q) - U(f, P)| ≤ M(d-c)ε/2,

where M is the maximum value of f on [a, b]. Similarly,

|L(f, Q) - L(f, P)| ≤ M(d-c)ε/2.

Therefore, we have

|U(f, Q) - L(f, Q)| ≤ M(d-c)ε/2 + ε/2 + M(d-c)ε/2 = ε.

Thus, f is integrable on [c, d].

The Maclaurin series for f(x) is:  f(x) = 7x - 7/32 x^6 + 7/768 x^10 - 7/36864 x^14 + ...

We can start by writing out the Maclaurin series for cos(x):

cos(x) = 1 - x^2/2! + x^4/4! - x^6/6! + ...

Next, we substitute 1/4 x^2 for x in the Maclaurin series for cos(x):

cos(1/4 x^2) = 1 - (1/4 x^2)^2/2! + (1/4 x^2)^4/4! - (1/4 x^2)^6/6! + ...

Simplifying this expression, we get:

cos(1/4 x^2) = 1 - x^4/32 + x^8/768 - x^12/36864 + ...

Finally, we multiply this series by 7x to obtain the Maclaurin series for f(x) = 7x cos(1/4 x^2):

f(x) = 7x cos(1/4 x^2) = 7x - 7/32 x^6 + 7/768 x^10 - 7/36864 x^14 + ...

So the Maclaurin series for f(x) is:

f(x) = 7x - 7/32 x^6 + 7/768 x^10 - 7/36864 x^14 + ...

Step-by-step explanation:

for a box plot, the line in the middle of the box is the median. in this example the line is at 10, so that's the median.

The Taylor polynomials of degree n approximating 1/(2-2x) for x near 0 are:

P3(x) = 1/2 - x + x^2 - x^3/2

P5(x) = 1/2 - x + x^2 - x^3/2 + 3x^4/8 - 5x^5/16

P7(x) = 1/2 - x + x^2 - x^3/2 + 3x^4/8 - 5x^5/16 + 35x^6/64 - 63x^7/128

To find the Taylor polynomials of degree n approximating 1/(2-2x) for x near 0, we need to compute the nth derivatives of the function and evaluate them at x=0. The nth derivative of 1/(2-2x) is:

f^(n)(x) = n!(2-2x)^-(n+1)

evaluated at x=0, we get:

f^(n)(0) = n!(2)^-(n+1) = n!/2^(n+1)

Using this formula, we can find the Taylor polynomial of degree n as follows:

Pn(x) = f(0) + f'(0)x + f''(0)x^2/2! + ... + f^(n)(0)x^n/n!

For n=3:

P3(x) = f(0) + f'(0)x + f''(0)x^2/2! + f'''(0)x^3/3!

= 1/2 - x + x^2 - x^3/2

For n=5:

P5(x) = f(0) + f'(0)x + f''(0)x^2/2! + f'''(0)x^3/3! + f''''(0)x^4/4! + f^(5)(0)x^5/5!

= 1/2 - x + x^2 - x^3/2 + 3x^4/8 - 5x^5/16

For n=7:

P7(x) = f(0) + f'(0)x + f''(0)x^2/2! + f'''(0)x^3/3! + f''''(0)x^4/4! + f^(5)(0)x^5/5! + f^(6)(0)x^6/6! + f^(7)(0)x^7/7!

= 1/2 - x + x^2 - x^3/2 + 3x^4/8 - 5x^5/16 + 35x^6/64 - 63x^7/128

Therefore, the Taylor polynomials of degree n approximating 1/(2-2x) for x near 0 are:

P3(x) = 1/2 - x + x^2 - x^3/2

P5(x) = 1/2 - x + x^2 - x^3/2 + 3x^4/8 - 5x^5/16

P7(x) = 1/2 - x + x^2 - x^3/2 + 3x^4/8 - 5x^5/16 + 35x^6/64 - 63x^7/128

We have shown that [tex]cov(x_1, x_1) = v(x_1) = \sigma^2_1(x 1 ,x 1 ).[/tex]

To show that [tex]cov(x_1, x_1) = v(x_1) = \sigma^2_1(x 1 ,x 1 )[/tex], we need to first understand what each of these terms means:

[tex]cov(x_1, x_1)[/tex] represents the covariance between the random variable x_1 and itself. In other words, it is the measure of how two instances of x_1 vary together.

v(x_1) represents the variance of x_1. This is a measure of how much x_1 varies on its own, regardless of any other random variable.

[tex]\sigma^2_1(x 1 ,x 1 )[/tex]represents the second moment of x_1. This is the expected value of the squared deviation of x_1 from its mean.

Now, let's show that [tex]cov(x_1, x_1) = v(x_1) = \sigma^2_1(x 1 ,x 1 ):[/tex]

We know that the covariance between any random variable and itself is simply the variance of that random variable. Mathematically, we can write:

[tex]cov(x_1, x_1) = E[(x_1 - E[x_1])^2] - E[x_1 - E[x_1]]^2\\ = E[(x_1 - E[x_1])^2]\\ = v(x_1)[/tex]

Therefore, [tex]cov(x_1, x_1) = v(x_1).[/tex]

Similarly, we know that the variance of a random variable can be expressed as the second moment of that random variable minus the square of its mean. Mathematically, we can write:

[tex]v(x_1) = E[(x_1 - E[x_1])^2]\\ = E[x_1^2 - 2\times x_1\times E[x_1] + E[x_1]^2]\\ = E[x_1^2] - 2\times E[x_1]\times E[x_1] + E[x_1]^2\\ = E[x_1^2] - E[x_1]^2\\ = \sigma^2_1(x 1 ,x 1 )[/tex]

Therefore, [tex]v(x_1) = \sigma^2_1(x 1 ,x 1 ).[/tex]

Thus, we have shown that [tex]cov(x_1, x_1) = v(x_1) = \sigma^2_1(x 1 ,x 1 ).[/tex]
