Using the following information, calculate the expected return and standard deviation of a portfolio with 50 percent in ABC and 50 percent in DEF. Then calculate the expected return and standard deviation of a portfolio where you invest 40 percent in ABC, 40 percent in DEF, and the rest in T-bills with a return of 3.5 percent.

15-24: Consider the following values for the dependent and independent variables:

                                         x                                        y

                                         5                                       10

                                         15                                     15

                                         40                                     25

                                         50                                     44

                                         60                                     79

                                         80                                     112

1. Develop a scatter plot of the dat Does the plot suggest a linear or nonlinear relationship between the dependent and independent variables?
2. Develop an estimated linear regression equation for the data. Is the relationship significant? Test at an α=0.05 level.
3. Develop a regression equation of the form y^=b₀+b₁x+b₂x². Does this equation provide a better fit to the data than that found in part b?

Teradene Corporation purchased land as a factory site and contracted with Maxtor Construction to construct a factory. Teradene made the following expenditures related to the acquisition of the land, building, and equipment for the factory: (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of $1 and PVAD of $1) (Use appropriate factor(s) from the tables provided.): Purchase price of the land $ 1,230,000 Demolition and removal of old building 83,000 Clearing and grading the land before construction 165,000 Various closing costs in connection with acquiring the land 45,000 Architect's fee for the plans for the new building 53,000 Payments to Maxtor for building construction 3,280,000 Equipment purchased 875,000 Freight charges on equipment 35,000 Trees, plants, and other landscaping 48,000 Installation of a sprinkler system for the landscaping 5,300 Cost to build special platforms and install wiring for the equipment 15,000 Cost of trial runs to ensure proper installation of the equipment 7,300 Fire and theft insurance on the factory for the first year of use 27,000 In addition to the above expenditures, Teradene purchased four forklifts from Caterpillar. In payment, Teradene paid $19,000 cash and signed a noninterest-bearing note requiring the payment of $73,000 in one year. An interest rate of 8% properly reflects the time value of money for this type of loan. Required: Determine the initial valuation of each of the assets Teradene acquired in the above transactions. (Round your answers to the nearest whole dollars.)

Problem Set 01:

The network for this task has two input nodes, one hidden layer consisting of two nodes, and one output node. It uses a ReLU activation

function. For the hidden layer, the weights for the first hidden node (from the input nodes) are (2.3, -0.64, 2). The last number is the

weight for the bias term. The weights for the second hidden node are (-3, -2, -1).

For the output layer, the weights are (5, 3, -34).

Calculate the output for the following inputs (where the bias term is the last value of each vector). Show your work.

1. (-4, -2, 1)

2. (0, -2, 1)

3. (4, -2, 1)

4. (0, -3, 1)

THE FOLLOWING QUESTION IS FOR C PROGRAMMING LANGUAGE

Printing the decimal equivalent of a binary number. Write a program that accepts an integer (5 digits or fewer) containing only 0s and 1s (i.e., binary) and prints out its decimal equivalent using the remainder and division operator to select the "binary" digits one at a time. Make sure your input is tested for multiple options: incorrect characters, too many, too few, etc.

I need help making this program. No loops, if else, or while statements are allowed. Thank you!
