A random variable X has a mean of 120 and a standard deviation of 15. A random variable Y has a mean of 100 and a standard deviation of 9. If X and Y are independent, approximately what is the standard deviation of X - Y
The standard deviation of x - y is 12
X and Y are independent random variables
For random variable X, mean =120 and standard deviation =15
For random variable Y, mean =100 and standard deviation = 9
Let D be the difference of standard deviation of X and Y.
Variance can be defined as the square of standard deviation.
Hence, Variance of X = (standard deviation of X)2 = (15)2 = 225
And, variance of Y = (standard deviation of Y)2 = (9)2 = 81
SD(X - Y) = sqrt(SD(X)2 - SD(Y)2)
Hence, D = sqrt(225 - 81) = sqrt(14) = 12
Hence, the standard deviation of x - y is 12

To whom are most interest group campaign contributions given in Congress?
Answer:
hm
Explanation:
Interest group campaign contributions in Congress are often given to lawmakers who hold positions of power or influence over policies that are of interest to the interest groups. This includes members of committees that have jurisdiction over issues that the interest group is concerned about, as well as members of leadership and those who are in tight re-election races.
In general, interest groups tend to donate more money to incumbents who have a track record of supporting their interests, as they are more likely to be re-elected and able to influence policy outcomes. However, interest groups also give money to challengers in races where the incumbent is not supportive of their interests, in the hopes of influencing the outcome of the election.
Some interest groups may also give more to one political party over the other, depending on which party's policies align more closely with their interests.
It's worth noting that there are regulations on campaign contributions, including limits on how much individuals and interest groups can give to candidates and parties. However, there are also loopholes and ways to get around these limits, such as through the use of Super PACs and other outside spending groups.

Each party presents a coherent set of programs to voters, consistent with its ideology and clearly different from those of the other party.
The candidates for each party pledge to support their party’s platform and to implement their party’s programs if elected.
Voters make choices based on which party’s programs most closely reflect their own ideas and hold the parties responsible for unkept promises by voting members out of office.
While governing, each party exercises control over its elected officials to ensure that party officials are promoting and voting for its programs, thereby providing accountability to voters.
What do the parties stand for?
Party ideology
Party membership
Policy differences between the parties
The dilemma party candidates face
Most Republican primary voters are very conservative, whereas most Democratic primary voters are very liberal, meaning that candidates must run to the extremes to win the party’s nomination

Answer: need more material.
Explanation:
As the Operations Manager at company, you must decide which product design, A or B,
has the higher reliability. B is designed with backup units for components R3 and R4 .
Determine the reliability of each design shown below?
product A
r1 r2 r3 r4
0.99--0.95--0.998--0.995-->
product b
r1 r2 r3 r4
0.99--0.95--0.985---0.99-->
----------------- l----------l
------------------0.95-----0.99
Answer:
To calculate the overall reliability of each product design, we need to use the formula for parallel and series connections of components.
For Product A, the overall reliability is:
0.99 x 0.95 x 0.998 x 0.995 = 0.9367 or 93.67%
For Product B, we can see that R3 and R4 are in parallel with each other, so we need to calculate their combined reliability first:
R3&R4 = 1 - (1-0.985) x (1-0.99) = 0.99415
Then, we can calculate the overall reliability of Product B:
0.99 x 0.95 x 0.99415 = 0.9316 or 93.16%
Therefore, based on these calculations, Product A has a higher reliability than Product B.
2: The pristine lake could be found high in the mountains, far away from the gritty metropolis.
A. pure
B. forgotten
C. mysterious
D. frozen
Answer:
A.) pure
The word "pristine" means in perfect condition, clean, and unspoiled. Therefore, in this context, the word "pristine" is used to describe the lake as being pure, untouched, and unspoiled, and free from pollution, dirt, or contamination. The other options, "forgotten," "mysterious," and "frozen," do not accurately describe the condition of the lake as portrayed in the sentence.

We have [tex] R(x,y)=p(x,y)+q(x,y) [\tex] because is the weekly total revenue function. If [tex] R(x,y)=R(80,40) [\tex], then we have,
[tex] x=80 [\tex]:
[tex] y=40 [\tex]:

[tex] p=200 -\frac{80}{5} -\frac{40}{10} [\tex]
[tex] p=200 -16 -4 [\tex]
[tex] p=180 [\tex]
and,

[tex] q=160 -8 -10 [\tex]
[tex] q=142 [\tex]
Then [tex] R(80,40)=180+142=322 [\tex], that means that Country Workshops earns 322 dollars per month under those conditions.
Analogously, If [tex] R(x,y)=R(60,100) [\tex] then [tex] p=178, q=129 [\tex], and [tex] R(60,100)=178+129=307 [\tex]. Country Workshops earns 307 dollars per month under those new conditions.

Lights, Camera, and More sells filmmaking equipment. The company offers three purchase options: (1) pay full cash today, (2) pay one-half down and the remaining one-half plus 10% in one year, or (3) pay nothing down and the full amount plus 15% in one year. George is considering buying equipment from Lights, Camera, and More for $60,000 and therefore has the following payment options: Payment Today Payment in One Year Total Payment Option 1 $60,000 $ 0 $60,000 Option 2 30,000 33,000 63,000 Option 3 0 69,000 69,000 Required: 1-a. Assuming an annual discount rate of 12%, calculate the present value and the total cost. 1-b. Which option's cost has the lowest present value?
Answer:
1-a. The present value for each payment option is:
Option 1: PV = $60,000 / (1 + 0.12)¹ = $53,571.43
Option 2: PV = [$30,000 / (1 + 0.12)¹] + [($33,000 / (1 + 0.12)²] = $50,446.43
Option 3: PV = $69,000 / (1 + 0.12)² = $53,571.43
The total cost for each payment option is:
Option 1: $60,000
Option 2: $63,000
Option 3: $69,000
1-b. Based on the present value calculations, option 2 has the lowest present value of $50,446.43. Therefore, option 2 is the best choice for George if he wants to minimize his total cost while taking into account the time value of money.
