Dupree Company produces three products - DBB-1, DBB-2, and DBB-3 from a joint process. Each product may be sold at the split-off point or processed further. Additional processing requires no special facilities, and production costs of further processing are entirely variable and traceable to the products involved. Key information about Dupree's production, sales, and costs follows. Units Sold Price (after additional processing) Separable Processing cost Units Produced Total Joint Cost Sales Price at Split-off DBB-1 16,000 $ 65 $ 110,000 16,000 $ 25 DBB-2 24,000 $ 50 $ 44,000 24,000 $ 35 DBB-3 36,000 $ 75 $ 66,000 36,000 $ 55 Total 76,000 $ 220,000 76,000 $ 3,600,000 The amount of joint costs allocated to product DBB-2 using the sales value at split-off method is: Multiple Choice $216,870. $939,130.

To determine whether the series $\sum_{n=2}^{\infty} \frac{1}{(4n+4)^5}$ converges or diverges, we will use the integral test. Step 1: What are the conditions to be able to apply the integral test? (Mark all that apply) $\frac{1}{(4x+4)^5}$ is positive on $[2, \infty)$ $\frac{1}{(4x+4)^5}$ is differentiable $\frac{1}{(4x+4)^5}$ is decreasing on $[2, \infty)$ Step 2: Compute the class of anti-derivatives of $\frac{1}{(4x+4)^5}$. (Hint: u substitution) $-\frac{1}{16(4x+4)^4}+C$ Step 3: Compute $\int_2^M \frac{1}{(4x+4)^5} dx$ (Give your answer using variable $M$) $-\frac{1}{16(4M+4)^4}+\frac{1}{331776}$ Step 4: Compute the value of the improper integral (If the integral diverges to $\infty$, type oo; if the integral diverges to $-\infty$, type -oo; and if the integral diverges for some other reason, type DNE.) $\int_2^{\infty} \frac{1}{(4x+4)^5} dx = \frac{1}{331776}$ Use your answer to help determine whether the series $\sum_{n=2}^{\infty} \frac{1}{(4n+4)^5}$ converges or diverges. Enter C if the series is convergent, D if the series is divergent, or ? if the Integral Test does not apply: C To determine whether the series $\sum_{n=2}^{\infty} \frac{1}{\sqrt{4n+4}}$ converges or diverges, we will use the integral test. Step 1: What are the conditions to be able to apply the integral test? (Mark all that apply) $\frac{1}{\sqrt{4x+4}}$ is decreasing on $[2, \infty)$ $\frac{1}{\sqrt{4x+4}}$ is positive on $[2, \infty)$ $\frac{1}{\sqrt{4x+4}}$ is differentiable Step 2: Compute the class of anti-derivatives of $\frac{1}{\sqrt{4x+4}}$ $\frac{\sqrt{4x+4}}{2}+C$ Step 3: Compute $\int_2^M \frac{1}{\sqrt{4x+4}} dx$ (Give your answer using variable $M$) $\frac{\sqrt{4M+4}}{2}-\sqrt{3}$ Step 4: Compute the value of the improper integral (If the integral diverges to $\infty$, type oo; if the integral diverges to $-\infty$, type -oo; and if the integral diverges for some other reason, type DNE.) $\int_2^{\infty} \frac{1}{\sqrt{4x+4}} dx = oo$ ```

The figure above shows a solid insulating sphere of radius $R_2$ with charge $-Q$ (where $Q > 0$) distributed uniformly throughout the volume. This sphere is centered within a thin spherical shell of radius $R_1$, and a charge $+Q$ is distributed uniformly on the surface of the spherical shell. Far away from the sphere and the spherical shell, the electric potential is zero. Use $k$ for Coulomb's constant. A. At point $A$ on the surface of the spherical shell, what is the electric potential $V_A$? B. Point $B$ is on the surface of the sphere. What is the potential difference, $V_B - V_A$? C. Point $C$ is at the center of the sphere. What is the potential difference, $V_C - V_B$?

For a function $f(x)$ that is integrable on the interval $[a, b]$, the average value of $f$ on $[a, b]$ is given by $$f_{avg} = \frac{1}{b - a} \int_a^b f(x) dx$$ Consider the function $f(x) = 5x^2 - 20x + 15$. (a) Find the average value of $f$ on the interval $[-6, 6]$ $f_{avg} = \text{_____}$ (b) Find all possible values of $c \in [-6, 6]$ (including endpoints) such that $f(c) = f_{avg}$. $c = \text{_____}$ Note: Since $f$ is continuous on $[-6, 6]$, the Mean Value Theorem for Integrals states that at least one $c$ must exist.

Question 13 Suppose that, in a Hidden Markov Model with three states, we have the estimates $ \xi_{t \mid t}=(0.2,0.6,0.2), \xi_{t+1 \mid t}=(0.3,0.4,0.3) $, and $ \xi_{t+1 \mid T}=(0.15,0.7,0.15) $. The transition matrix is given by: \[ P=\left(\begin{array}{ccc} 0.5 & 0.25 & 0.25 \\ 0.25 & 0.5 & 0.25 \\ 0.25 & 0.25 & 0.5 \end{array}\right) \] What are the optimal forecasts $ \xi_{t \mid T}(j) $ for each state $ j=\{1,2,3\} $ using backward smoothing (aka the Kim smoother)? $ \xi_{t \mid T}=(0.1625,0.675,0.1625) $ $ \xi_{t \mid T}=(0.125,0.75,0.125) $ $ \xi_{t \mid T}=(0.1125,0.775,0.1125) $ $ \xi_{t \mid T}=(0.15,0.7,0.15) $
