a) The 95% confidence interval for the probability (p) that a randomly selected component lasts more than 350 hours is estimated to be between 0.4947 and 0.8753. b) The 95% confidence interval for the probability (p) that a system consisting of two components connected in series lasts more than 350 hours is estimated to be between p² and 2p - p²

a) To calculate the confidence interval, we can use the formula for the confidence interval of a proportion. The point estimate for p is the proportion of components in the sample that lasted longer than 350 hours, which is 24/37 = 0.6486. We can calculate the standard error (SE) using the formula:

SE = \(\sqrt{\frac{p\times(1-p)}{n}\)

where p is the point estimate and n is the sample size. Plugging in the values, we get:

SE = sqrt[(0.6486*(1-0.6486))/37] ≈ 0.0841

Next, we can use the standard normal distribution (Z-distribution) for a 95% confidence interval, which corresponds to a Z-score of 1.96 (for a two-tailed test). We can then multiply the SE by the Z-score to get the margin of error (ME):

ME = Z * SE = 1.96 * 0.0841 ≈ 0.1648

Finally, we can construct the confidence interval by adding and subtracting the margin of error from the point estimate:

95% Confidence Interval = p ± ME = 0.6486 \(\pm\) 0.1648

So the confidence interval for p is approximately (0.4947, 0.8753), which means we are 95% confident that the true probability of a component lasting more than 350 hours is between 0.4947 and 0.8753.

b) Since the two components in the system are connected in series, the system will operate only if both components operate properly. Therefore, the probability that the system lasts more than 350 hours is the probability that both components operate properly, which is the product of their individual probabilities. Let p1 and p2 be the probabilities of the first and second components lasting more than 350 hours, respectively.

Based on the assumption that the life times of the two components are independent, the probability that both components operate properly is given by p1 * p2. Since p1 and p2 are assumed to be equal to p (the probability of a single component lasting more than 350 hours), we can write the probability of the system lasting more than 350 hours as p * p = p².

To calculate the lower bound of the confidence interval, we can simply square the lower bound of the confidence interval for p (i.e., p²). To calculate the upper bound of the confidence interval, we can subtract the lower bound of the confidence interval for p from 2p (i.e., 2p - p²).

So the 95% confidence interval for the probability that the system lasts more than 350 hours is estimated to be between p² and 2p - p², where p is the probability of a single component lasting more than 350 hours.

According to the given question.

We have an equation

2x + 2/y = 4w + 2

Since, we have to find the value of x for the given equation

2x + 2/y = 4w + 2

Thereofore,

2x + 2/y = 4w + 2

⇒ 2(x + 1)/y = 2(2w + 1)    (taking 2 common from both the sides)

⇒ (x + 1)/y = 2w + 1

⇒ (x + 1) = y(2w + 1)         (multiplying both the sides by y)

⇒ x + 1 = 2yw + y

⇒ x = 2yw + y - 1         ( subtracting 1 both the sides)

Step-by-step explanation:

The given series is an illustration of an arithmetic series, where the sum of first 10 terms of the series is -160.

Given

\(2 + (-2) + (-6) + (-10) +.......\)

First, we calculate the common difference of the series

\(d = T_2 - T_1\)

\(d = -2 -2\)

\(d = -4\)

The sum of the first nth term of an arithmetic series is:

\(S_n = \frac n2(2a + (n - 1)d)\)

Where:

\(n = 10\) ---- i.e. sum of 10 terms

\(a = 2\) --- the first term

\(d = -4\) --- the common difference

So, we have:

\(S_{10} = \frac{10}{2}(2 \times 2 + (10 - 1) \times -4)\)

\(S_{10} = 5(4 + 9 \times -4)\)

\(S_{10} = 5(-32)\)

\(S_{10} = -160\)

Hence, the sum of 10 terms of the series is -160.

Answer:

Step-by-step explanation:

a. The price elasticity of blue jeans on the weekend is approximately -2.14, indicating that a 1% decrease in price will result in a 2.14% increase in quantity demanded.

b. The quantity demanded of blue jeans will increase by approximately 10.7%.

a. The price elasticity of demand measures the responsiveness of the quantity demanded to a change in price. It is calculated as the percentage change in quantity demanded divided by the percentage change in price.

Given:

Price = $40

Price of khakis = $50

Advertising = $2

Weekend (dummy variable) = 1 (indicating it is the weekend)

To calculate the price elasticity of blue jeans on the weekend, we need to use the coefficient for the "Price" variable from the regression results.

Price elasticity of demand = (Coefficient for Price * Price) / Quantity demanded

Coefficient for Price = -4.5 (from regression results)

Price = $40 (given)

Quantity demanded can be calculated using the regression equation:

Quantity demanded = Intercept + (Coefficient for Price * Price) + (Coefficient for Price Khakis * Price of khakis) + (Coefficient for Advertising * Advertising) + (Coefficient for Weekend * Weekend)

Intercept = 200 (from regression results)

Coefficient for Price Khakis = 2.2 (from regression results)

Coefficient for Advertising = 6.5 (from regression results)

Coefficient for Weekend = 10.0 (from regression results)

Quantity demanded = 200 + (-4.5 * 40) + (2.2 * 50) + (6.5 * 2) + (10.0 * 1)

Quantity demanded = 200 - 180 + 110 + 13 + 10

Quantity demanded = 153

Now we can calculate the price elasticity of demand:

Percentage change in quantity demanded = (Quantity demanded - Quantity demanded with a 5% price decrease) / Quantity demanded

Percentage change in quantity demanded = (153 - Quantity demanded with a 5% price decrease) / 153

Percentage change in price = 5% (given)

Price elasticity of demand = (Percentage change in quantity demanded / Percentage change in price) * (Price / Quantity demanded)

Price elasticity of demand = ((153 - Quantity demanded with a 5% price decrease) / 153) / 0.05 * (40 / 153)

To find the quantity demanded with a 5% price decrease, we calculate:

New price = $40 - (5% of $40) = $40 - ($2) = $38

New quantity demanded = 200 + (-4.5 * 38) + (2.2 * 50) + (6.5 * 2) + (10.0 * 1)

New quantity demanded = 200 - 171 + 110 + 13 + 10

New quantity demanded = 162

Substituting the values into the formula:

Price elasticity of demand = ((153 - 162) / 153) / 0.05 * (40 / 153)

Price elasticity of demand = (-0.059 / 0.05) * (40 / 153)

Price elasticity of demand ≈ -2.14

The price elasticity of blue jeans on the weekend is approximately -2.14, indicating that a 1% decrease in price will result in a 2.14% increase in quantity demanded.

b. We already calculated the price elasticity of demand (-2.14). Now, we can use this elasticity to determine the percentage change in quantity demanded when the price is reduced by 5%.

Percentage change in price = -5% (given)

Percentage change in quantity demanded = Price elasticity of demand * Percentage change in price

Percentage change in quantity demanded = -2.14 * (-5%)

Percentage change in quantity demanded = 10.7%

Therefore, if the price of blue jeans is reduced by 5%, the quantity demanded will increase by approximately 10.7%.

In a scatter plot, if all data points were aligned along a 44º angle, the correlation would be 0. The correct answer is D.

In a scatter plot, the correlation coefficient measures the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative linear relationship, 1 indicates a perfect positive linear relationship, and 0 indicates no linear relationship.

When all data points are aligned along a 44º angle, it means that the points are distributed randomly and do not follow a clear linear pattern. There is no consistent increase or decrease in one variable as the other variable changes. Therefore, the correlation between the variables is 0, indicating no linear relationship or strength of association.

In other words, the angle of 44º suggests that the variables are unrelated and have no linear dependency on each other.

Answer:

Step-by-step explanation:

If you want to know what you have to multiply by 5 to get a product of 70, you would divide 70 by 5 to get that other number. Because 70 divided by 5 is 14, you know that the other number is 14. It's the same when you have one factor of a polynomial and want to know the other. You divide your polynomial by the one factor to get to the other factor, because when you multiply them together, you get back the polynomial you started with. Like when we found that 70 / 5 = 14, we know that when we multiply 14 by 5 we'll get the 70 we started with.

Long division of polynomials will be difficult to illustrate within this forum, but I'll do my best. What we want to do is divide \(6x^2+x-15\) by 2x - 3:

          __________

2x - 3 | \(6x^2+x-15\)

First divide the 6 x-squared by the 2x (forget about the rest of what's inside the box for now, and also forget about the -3 for now. We'll deal with them later).  2x goes into 6 x-squared 3x times, because 2x * 3x = 6x-squared, right? So the 3x goes above the 6x-squared:

           3x_______

2x - 3 | \(6x^2+x-15\)

Now we multiply the 3x by the 2x and put that product under the 6x-squared. The product is 6x-squared (which will always be the case in division that they will subtract each other away. That's why we do this!)Then multiply the 3x by the -3 which is -9 and put that under the "+x" term:

           3x________

2x - 3 | \(6x^2+x-15\)

           6x^2-9x        

At this point we change the signs and have

            3x                

2x - 3   | 6x^2 + x - 15

          -  6x^2 +9x

And then we add and bring down the -15:

           3x                  

2x - 3 | 6x^2  + x - 15

         - 6x^2 + 9x

                       10x - 15

Now do the division process again, this time dividing 10x by 2x (again the -3 will wait). 10x divided by 2x is 5 (because 2x * 5 = 10x, right?). The 5 goes above the +x on top:

           3x    +   5      

2x - 3 | 6x^2 +  x - 15

        -  6x^2 + 9x

                       10x - 15

Now we wwill multiply the 5 by both the 2x and the -3 and subtract:

           3x     +  5    

2x - 3 | 6x^2 +  x - 15

         - 6x^2 + 9x

                       10x - 15

                     - 10x + 15

Notice that when we subtracted, the 10x changed from + to -, and the -15 changed to a positive. The remainder is 0.

That tells us that the other factor of the polynomial is 3x + 5. You could also have done synthetic division, but it would be more difficult than this to illustrate because you would be dividing by 3/2.  :/

The total possibilities (outcomes) of 9 elements in a row is:

P(₉) = 9!

P(₉) = 9*8*7*6*5*4*3*2*1

P(₉) = 362880

And the outcomes in which they are adjacent to each other is:

We consider them as one unit them we in this situation have 8 elements

P(₈) = 8!

P(₈) = 8*7*6*5*4*3*2*1

P(₈) = 40320

Then the probability that the married couple will have nonadjacent desks is:

P = P(₉)  -  P(₈) / P(₉)
