If x and y be  i.i.d. unif(0, 1), then the covariance of x + y and x - y is zero.

Yes, x y are x y independent studysoup.

Here  x and y be i.i.d. unif(0, 1)

The i.i.d stands for independent and identically distributed

unif means that the uniformly distributed

Here x and y are i.i.d unif (0,1)

The covariance is defined as the relationship between the two random variables . Therefore, variance of one variable is equal to the change in another variable

Here we have to find the covariance of x + y and x - y

According to the properties of covariance

Cov(x+ y, x - y) = Cov (x, x) + Cov(y, x) - Cov(x, y) - Cov(y, y) = 0

Because Cov(x, x) = Cov (y, y)

Cov(y, x) = Cov(x, y)

Therefore, the covariance of x+y and x - y is 0.

Answer:

f(-4) = -6

g(2) = -14

Step-by-step explanation:

To evaluate a function we must plug in the values of x. So for:

f(x) = 2x+2

we have:

f(-4) = 2(-4)+2

then we simplify:

f(-4) = -8+2

so f(-4) = -6

Now the same steps are taken for g(x) in which the answer would be -14.

Answer:

50.75

Step-by-step explanation:

We have:

\(E[g(x)] = \int\limits^{\infty}_{-\infty} {g(x)f(x)} \, dx \\\\= \int\limits^{1}_{-\infty} {g(x)(0)} \, dx+\int\limits^{6}_{1} {g(x)\frac{2}{x} } \, dx+\int\limits^{\infty}_{6} {g(x)(0)} \, dx\\\\= \int\limits^{6}_{1} {g(x)\frac{2}{x} } \, dx\\\\=\int\limits^{6}_{1} {(4x+3)\frac{2}{x} } \, dx\\\\=\int\limits^{6}_{1} {(4x)\frac{2}{x} } \, dx + \int\limits^{6}_{1} {(3)\frac{2}{x} } \, dx\\\\=\int\limits^{6}_{1} {8} \, dx + \int\limits^{6}_{1} {\frac{6}{x} } \, dx\\\\\)

Answer:

b = a + 4

Step-by-step explanation:

I just plugged in a to the equation. Heres my work:

b = 4 + 4 , b = 8

b = 8 + 4, b = 12

b = 12 + 4, b = 16

b = 16 + 4, b = 20

After substituting, the correct equation for the table is, b = a + 4

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

We have to given that;

The values of a and b from table is,

a = 4, 8, 12, 16

b = 8, 12, 16, 20

Substitute the values of a and b in all options, we check the correct option as;

By option 2;

The equation is,

⇒ b = a + 4

Substitute a = 4;

⇒ b = 4 + 4

⇒ b = 8

Substitute a = 8;

⇒ b = 8 + 4

⇒ b = 12

Therefore, 'Option 2' shows the correct equation for the given table.

The objective function is given as:

z=−3x+5y

The constraints are

x+y≥−2

3x−y≤2

The total prorations for interest and property taxes to the nearest $100 are:

Proration for interest: $517

Proration for property taxes: $1,754

To calculate the total prorations for interest and property taxes, we need to determine how much the seller owes for each of these expenses up to the closing date of June 15.

First, let's calculate the daily interest rate on the mortgage. We can do this by multiplying the principal amount of the mortgage ($168,745.60) by the annual interest rate (8%) and then dividing by 365 (the number of days in a year):

Daily interest rate = ($168,745.60 x 0.08) / 365 = $36.94

Next, we need to determine the number of days from the start of the month (June 1) to the closing date (June 15):

Number of days = 15 - 1 = 14

Using the daily interest rate and the number of days, we can calculate the proration for interest:

Proration for interest = ($36.94 x 14) = $516.76

To calculate the proration for property taxes, we need to divide the annual property taxes ($3,893.25) by 365 to get the daily property tax rate:

Daily property tax rate = $3,893.25 / 365 = $10.65

Next, we need to determine the number of days from the start of the year to the closing date (June 15):

Number of days = 165

Using the daily property tax rate and the number of days, we can calculate the proration for property taxes:

Proration for property taxes = ($10.65 x 165) = $1,754.25

Therefore, the total prorations for interest and property taxes to the nearest $100 are:

Proration for interest: $517

Proration for property taxes: $1,754

These prorations will be subtracted from the seller's equity, since they are expenses that the seller owes up to the closing date.

Step-by-step explanation:

To find the new coordinate of a point after it has been scaled by a factor of 1/2, you can multiply the x- and y-coordinates of the point by 1/2.

For example, to find the new coordinate of point K', you can multiply the x-coordinate of K' (-8) by 1/2 to get the new x-coordinate, and multiply the y-coordinate of K' (8) by 1/2 to get the new y-coordinate. This gives you the new coordinate of K' as (-4,4).

You can use the same method to find the new coordinates of points L' and M'. The new coordinate of L' is (4,4) and the new coordinate of M' is (-2,4).

Answer:

C

Step-by-step explanation:

Let's assume the number of cookies Lily bought is represented by "C," and the number of brownies is represented by "B."

According to the problem, the cost of one cookie is $2, and the cost of one brownie is $3. Lily spent a total of $144.

We can set up two equations based on the given information:

C + B = 60 (equation 1, representing the total number of sweets)

2C + 3B = 144 (equation 2, representing the total cost in dollars)

To solve this system of equations, we can use substitution or elimination method. Here, we'll use the substitution method.

From equation 1, we can rewrite it as C = 60 - B.

Now substitute this value of C in equation 2:

2(60 - B) + 3B = 144

Simplify the equation:

120 - 2B + 3B = 144

Combine like terms:

120 + B = 144

Subtract 120 from both sides:

B = 144 - 120

B = 24

Now substitute the value of B back into equation 1 to find C:

C + 24 = 60

C = 60 - 24

C = 36

Therefore, Lily bought 36 cookies and 24 brownies.

Answer:

a)2.09

b) 0.2

c) 130 correspondents

d) 5.38 hours per day

e) 69%

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ,

where

x is the raw score,

μ is the population mean,

σ is the population standard deviation.

Mean = average of 2.98 hrs/day, Standard deviation = 2.4 hours.

a) What is the Z score for a person who watches more than 8 hrs/day.

z = (x-μ)/σ

= 8 - 2.98/2.4

= 2.09167

≈ 2.09

b) What proportion of people watch 5 hrs/day or more television?

z = (x-μ)/σ

= 5 - 2.98/2.4

= 0.84167

P-value from Z-Table:

P(x<5) = 0.80001

The proportion that watches 5 hrs/day or more television?

P(x>5) = 1 - P(x<5) = 0.19999

≈ 0.2

c) How many does this correspond to in the sample?

From the question we are told:

650 GSS respondents in 2006 watched television for an average of 2.98 hrs/day, with a standard deviation of 2.4 hours.

Hence, the proportion that corresponds to people who watch 5 hrs/day or more television form the samples is

0.2 × 650

= 130 correspondents.

d) What number of television hours per day corresponds to a Z +1.

z = (x-μ)/σ

+1 = x - 2.98/2.4

Cross Multiply

1 × 2.4 = x - 2.98

2.4 = x - 2.98

x = 2.4 + 2.98

x = 5.38 hours per day

e) What is the percentage of people who watch between 1 and 6 hours of television per day?

Step 1

For 1 hour

z = (x-μ)/σ

= 1 - 2.98/2.4

= -0.825

Probability value from Z-Table:

P(x = 1) = 0.20469

Step 2

For 6 hours

z = (x-μ)/σ

= 6 - 2.98/2.4

= 1.25833

Probability value from Z-Table:

P(x = 6) = 0.89586

The percentage of people who watch between 1 and 6 hours of television per day is

P(x = 6) - P(x = 1)

= 0.89586 - 0.20469

= 0.69117

Converting to percentage =

0.69117 × 100

= 69.117 %

Approximately = 69%
