Suppose you are considering purchasing a 2-stock portfolio that will hold shares in IBM and PepsiCo and that you believe the stocks will perform as follows: IBM PepsiCo Expected Return 15% 10% Standard Deviation 25% 16% Assume there is -0.20 correlation between the two stocks. Question 46 (1 point) What is the Covariance between IBM and PepsiCo? Question 46 options: a) 0.0080 b) 0.0000 c) -0.2000 d) -0.0080 Question 47 (1 point) What is the Portfolio Return of a Portfolio split 70% in IBM and 30% in PepsiCo? Question 47 options: a) 12.78% b) 13.00% c) 13.50% d) 14.00% Question 48 (1 point) What is the Portfolio Standard Deviation of a Portfolio split 80% in IBM and 20% in PepsiCo? Question 48 options: a) 12.17% b) 12.78% c) 17.20% d) 19.61% Question 49 (1 point) Looking at a Portfolio split 60% in IBM and 40% in PepsiCo, which of the following statements is true? Question 49 options: a) The subject portfolio has an expected return of 11.00% and standard deviation of 12.78% which makes an inefficient portfolio b) The subject portfolio has an expected return of 13.00% and standard deviation of 15.09% which makes an inefficient portfolio c) The subject portfolio has an expected return of 11.00% and standard deviation of 12.78% which makes an efficient portfolio d) The subject portfolio has an expected return of 13.00% and standard deviation of 15.09% which makes an efficient portfolio Question 50 (1 point) Looking at a Portfolio split 20% in IBM and 80% in PepsiCo, which of the following statements is true? Question 50 options: a) The subject portfolio has an expected return of 11.00% and standard deviation of 12.78% which makes an inefficient portfolio b) The subject portfolio has an expected return of 13.00% and standard deviation of 15.09% which makes an inefficient portfolio c) The subject portfolio has an expected return of 11.00% and standard deviation of 12.78% which makes an efficient portfolio d) The subject portfolio has an expected return of 13.00% and standard deviation of 15.09% which makes an efficient portfolio

1. Comparing Performance Characteristics of Two Computing Systems: (5 points) Computing system #1 has a single issue, scalar, in-order pipeline and a system clock rate of 3 GHz. It is being used to run a vector multiply-add (axpy) benchmark with a 10,000 element, 32-bit, integer data type vector. The benchmark executes at a sustained rate of 10 cycles per arithmetic operation (CPO = 10). Assume there is no (zero) overhead/penalty for memory fetches. Computing system #2 is also a single issue, scalar, in-order pipeline machine. It has a clock rate of 4.1 GHz, and different architecture which will execute the benchmark at 8 cycles per arithmetic operation (CPO =8). (a) What will the execution time be for the vector multiply add benchmark when it is run on computing system #2? Show all the steps used to evaluate the execution time, and clearly state any additional assumptions you make in your analysis. (b) What will the speed up of Computing System #2 relative to Computing System #1 be ? Show all the steps used to evaluate the execution time, and clearly state any additional assumptions you make in your analysis.

Let \( I \) be an interval and \( f: I \rightarrow \mathbb{R} \) be a continuous function. Select the statements that are true. If \( f \) is monotone, then \( f \) is injective. If \( f \) is injective, then \( f \) is strictly increasing. If \( f \) is injective, then \( f \) is strictly monotone. If \( f \) is injective, then the inverse function \( f^{-1}: f(I) \rightarrow I \) is continuous.

How is Hashing different from encryption? They are the same Unlike Encryption which is 2 way- meaning it can be decrypted. Hashing is a one-way encryption method meaning it can not be decrypted. Unlike Encryption which is 1 way meaning it can’t be decrypted. Hashing is a two-way encryption method allowing for decryption Encryption is the term used to explain our modern encryption process, while hashing is purely a theoretical model of encryption used for teaching

Suppose during 2022 that Cypress Semiconductor Corporation reported net cash provided by operating activities of $108,056,630, cash used in investing of $52,182,460, and cash used in financing of $8,915,280. In addition, cash spent for fixed assets during the period was $31,245,830. No dividends were paid. Calculate free cash flow. (Show a negative free cash flow with either a - sign e.g. -15,000 or in parenthesis e.g. (15,000).) Free cash flow $

Tutorial Exercise Find $\frac{dx}{dt}$, $\frac{dy}{dt}$, and $\frac{dy}{dx}$. $x = 8t^3 + 6t$, $y = 9t - 7t^2$ Step 1 We are given the following parametric equations and asked to find derivatives with respect to t and also $\frac{dy}{dx}$. $x = 8t^3 + 6t$ $y = 9t - 7t^2$ Recall that x and y are simply functions of t, so we find their derivatives with respect to t as usual. $\frac{dx}{dt} = $ $\frac{dy}{dt} = $
