The probability in the two fair dice problem is given as [tex]P(A|B) = 1/6[/tex].

To find [tex]P(A|B)[/tex], we first need to find [tex]P(B)[/tex], which is the probability that two dice are showing different faces.

The total number of possible outcomes when rolling two dice is [tex]6x6 = 36[/tex]. Out of these [tex]36[/tex] possible outcomes, there are [tex]6[/tex] outcomes where both dice show the same face (e.g., both dice show a 1). Therefore, there are [tex]36-6=30[/tex] outcomes where two dice show different faces.

Hence, P(B) = [tex]30/36 = 5/6[/tex].

Next, we need to find the probability of A and B occurring together, i.e., P(A and B).

The possible pairs of faces that add up to 10 are [tex](4,6), (6,4),[/tex] and [tex](5,5)[/tex]. Each of these pairs can occur in 2 ways (e.g., the pair [tex](4,6)[/tex] can occur as [tex](4,6) or (6,4))[/tex]. Therefore, there are 6 ways in total for the sum of two dice to be 10.

Out of these 6 outcomes, only one outcome (the pair (5,5)) violates condition B (i.e., both dice showing the same face). Therefore, there are [tex]6-1=5[/tex] outcomes where the sum of the two dice is 10 and the two dice show different faces.

Hence, P(A and B) [tex]= 5/36[/tex].

Using the formula for conditional probability, we can find P(A|B) as:

[tex]P(A|B) = P(A and B) / P(B) = (5/36) / (5/6) = 1/6.[/tex]

Therefore, [tex]P(A|B) = 1/6[/tex], which is the required probability.

The stocks would need to increase in value by 23% to return to their original value. Rounding to the nearest tenth of a percent, the answer is 23.0%.

Let x be the percentage increase in the value of the stocks needed to return to their original value. Since the value of the stocks decreased by 23%, the new value of the stocks is 100% - 23% = 77% of the original value.

Therefore, we can set up the equation:

(100% + x%) = (77%)*(100%)

Simplifying this equation, we get:

100% + x% = 77%

x% = 77% - 100%

x% = -23%

Since we want to find the percentage increase, we need to take the absolute value of -23%, which is 23%.

Therefore, the stocks would need to increase in value by 23% to return to their original value. Rounding to the nearest tenth of a percent, the answer is 23.0%.

The function giving the distance between the point (0,-6) and the line y = 8x - 5 is: S = 47 / sqrt(65).

To find the point on the line closest to the point (0,-6), we can find the perpendicular distance from the point (0,-6) to the line y = 8x - 5. The point on the line closest to (0,-6) will be the point on the line that is intersected by the perpendicular line.

The slope of the given line is 8, so the slope of any line perpendicular to it will be -1/8. Let (a,b) be the point on the line y = 8x - 5 that is closest to (0,-6). The equation of the line passing through (0,-6) with slope -1/8 is:

y + 6 = (-1/8)x

Simplifying this equation, we get:

y = (-1/8)x - 6

The point (a,b) will lie on both the given line and the perpendicular line. Therefore, we can substitute y = 8x - 5 in the equation y = (-1/8)x - 6 to obtain:

8x - 5 = (-1/8)x - 6

Solving for x, we get:

x = 37/65

Substituting x = 37/65 in y = 8x - 5, we get:

y = 231/65

Therefore, the point on the line y = 8x - 5 closest to the point (0,-6) is (37/65, 231/65).

The distance S between the point (0,-6) and the line y = 8x - 5 can be found by using the formula:

S = |ax + by + c| / sqrt(a^2 + b^2)

where a, b, and c are the coefficients of the general form of the line equation, which is ax + by + c = 0.

In this case, the equation of the line is y - 8x + 5 = 0. Therefore, a = -8, b = 1, and c = 5. Substituting these values in the formula for S, we get:

S = |(-8)(0) + (1)(-6) + 5| / sqrt((-8)^2 + 1^2)

= 47 / sqrt(65)

Therefore, the function giving the distance between the point (0,-6) and the line y = 8x - 5 is:

Numerator: e^(1 + ln ∞) * (1/∞) = e^(1 + ∞) * 0 = 0, Denominator: 1 + e^∞ = ∞. So, the limit of the expression is: lim (x→∞) [e^(1 + ln x) / ln (1 + e^x)] = 0/∞ = 0

To find the limit of the given function, let's first rewrite the terms using the provided limit notation:

lim (x→∞) [e^(1 + ln x) / ln (1 + e^x)]

To solve this limit, we will apply L'Hôpital's rule, which states that if the limit has the form 0/0 or ∞/∞, we can find the limit by taking the derivative of the numerator and denominator with respect to x:

Numerator: d(e^(1 + ln x))/dx = e^(1 + ln x) * d(1 + ln x)/dx = e^(1 + ln x) * (1/x)
Denominator: d(ln(1 + e^x))/dx = (1/(1 + e^x)) * d(e^x)/dx = (1/(1 + e^x)) * e^x

Now, we will find the limit of the new expression:

lim (x→∞) [(e^(1 + ln x) * (1/x)) / ((1/(1 + e^x)) * e^x)]

Simplify the expression by canceling out the e^x terms:

lim (x→∞) [(e^(1 + ln x) * (1/x)) / (1 + e^x)]

Now, let's substitute x→∞:

Numerator: e^(1 + ln ∞) * (1/∞) = e^(1 + ∞) * 0 = 0
Denominator: 1 + e^∞ = ∞

The pickup truck wheel travels 37.7 inches farther in one revolution than the compact car wheel.

The distance traveled by a wheel in one revolution is directly proportional to the diameter of the wheel.

Since the diameter of the compact car wheel is 33 inches, its circumference (the distance traveled in one revolution) is 103.67 inches (C = πd). On the other hand, the radius of the pickup truck wheel is 19 inches, making its diameter 38 inches and its circumference 119.38 inches.

Therefore, the pickup truck wheel travels 15.71 inches more in one revolution than the compact car wheel (119.38 - 103.67 = 15.71). However, the question asks for the distance in inches farther, which means we need to subtract the circumference of the compact car wheel from that of the pickup truck wheel.

Hence, the answer is 37.7 inches (2 × 15.71 + 2 × 103.67 = 241.76 - 204.06 = 37.7).

| 5([tex]k(-1)^k + 1) / k^2[/tex] |
Step 2: Simplify the absolute value
[tex]5(k + (-1)^k) / k^2[/tex]
Step 3: Use the Comparison Test
We will compare this series to the series ∑ 5k / [tex]k^2,[/tex] k = 1 to ∞.

Since [tex](-1)^k[/tex] is always either 1 or -1, we know that [tex]5(k + (-1)^k) / k^2 \leq 5k / k^2.[/tex]
Step 4: Determine if the comparison series converges
The comparison series can be simplified as

∑ 5 / k, k = 1 to ∞, which is a harmonic series that is known to be divergent.
Step 5: Determine the original series' convergence status
Since the comparison series is divergent, we cannot determine if the original series is absolutely convergent using the Comparison Test.
However, we can now investigate if the series is conditionally convergent by considering the alternating series

∑ (-1)^k(5k) / [tex]k^2[/tex], k = 1 to ∞.
Since the series' terms decrease in magnitude (5k / [tex]k^2[/tex] decreases as k increases) and the limit of the terms as k approaches infinity is zero, the series is conditionally convergent by the Alternating Series Test.

The 98% confidence interval for the true mean salary of employees in the Department of Health and Human Services is (34.85, 42.27) thousands of dollars
To find the 98% confidence interval for the true mean salary of employees in the Department of Health and Human Services, we can use the following formula:

CI = x ± t*(s/√n)

where:

x is the sample mean
t is the critical t-value from the t-distribution with n-1 degrees of freedom and a confidence level of 98%
s is the sample standard deviation
n is the sample size
First, we need to calculate the sample mean and sample standard deviation:

Sample mean:
x= (28.5 + 32.1 + ... + 44.8) / 27 = 38.56

Sample standard deviation:
s = sqrt[((28.5-38.56)^2 + (32.1-38.56)^2 + ... + (44.8-38.56)^2) / (27-1)] = 6.05

Next, we need to find the critical t-value using a t-distribution table or Excel function.


Since we have a sample size of n = 27 and a confidence level of 98%, the degrees of freedom is n-1 = 26. Using Excel function "=TINV(0.01, 26)", we get a t-value of 2.485.

Substituting the values into the formula, we get:

The function that can be used to find the amount in dollars a passenger has to pay to fly with `p` pieces of luggage, where `p > 2` is: `C(p) = 439 + 25(p-2)`

- The base cost of the flight is $439.

- Customers may check 2 pieces of luggage without any additional fee.

- For each additional piece of luggage beyond 2, there is a fee of $25.

- If `p` is the number of pieces of luggage checked, then the number of additional pieces of luggage beyond 2 is `p - 2`.

- Therefore, the additional fee for `p` pieces of luggage beyond the first 2 is `25(p - 2)`.

- Adding this fee to the base cost gives the total cost `C(p)`:

the value of y is -5/8. So, In part (a), we found that the rational function f(x) = (5x + 20)/(x^2 - 20) had a vertical asymptote at x = -2√5 and x = 2√5, a horizontal asymptote at y = 0, an x-intercept at (-4, 0), a y-intercept at (0, -1), and a hole at (-4, 5/18).

To find the value of y when x = -6, we simply substitute -6 for x in the function:

f(-6) = (5(-6) + 20)/((-6)^2 - 20)

We simplify this expression by first multiplying 5 and -6 to get -30, and then adding 20 to get -10 in the numerator. In the denominator, we evaluate (-6)^2 to get 36, and then subtract 20 to get 16. So, we have:

f(-6) = -10/16

This fraction can be simplified by dividing both the numerator and denominator by 2:

The function with the larger y-intercept is h, because it intersects the y-axis at a higher point than f.

To determine which function, f or h, has a larger y-intercept, we need to look at the graphs of the two functions. From the graph, we can see that function h has a larger y-intercept than function f.

The y-intercept of function h is approximately 4, while the y-intercept of function f is approximately 2. Therefore, we can conclude that the x-value of function h's y-intercept is larger than that of function f.

This is because the y-intercept of a function is the point at which it intersects with the y-axis, and the value of the x-coordinate at that point determines the x-value of the y-intercept.

= ∫[0,1] [(4-2y)∫[0,1]S SCH dx]dy

= ∫[0,1] [(4-2y)(1-0)]dy

= ∫[0,1] (4-2y)dy

= 4y-y^2/2 | from 0 to 1

= 4-2-0

= 2

Therefore, the double integral is equal to 2, which represents the volume of the solid over the region R=[0, 1] x [0, 1].
