Question Solved1 Answer please please solve all parts of this question. i will rate your work 2. (a) You are stranded on a deserted island. Mushrooms of various types grow wildly all over the island, but no other fod is anywhere to be found. Some of the mushrooms have been determined as poisonous and others as not determined by your former companions' trial and error). You are the only one remaining on the island. You have the following data to consider. Example IsHeavy IsSmelly IsSpotted IsSmooth isPoisonous A 0 0 0 0 0 1 0 0 0 B 0 0 с 1 1 1 0 1 1 E 0 1 1 0 0 0 1 1 1 0 0 0 1 1 1 1 0 1 LUI > 3 1 U 1 1 1 ? 0 1 ? ? w 1 1 0 0 You know whether or not mushrooms A through H are poisonous, but you do not know about through W. For the first couple of questions, consider only mushrooms A through H. (1) What is the entropy of IsPoisonous ? (1) Which variable should you choose as the root of a decision tree? (H) What is the information gain of the variable you chose in the previous question? (iv) Build a decision tree to classily mushrooms as poisonous or not. (v) Classily mushrooms U, V, and W using this decision tree as poisonous or not pol- sonous (vi) If the mushrooms of A through H that you know are poisonous suddenly became scarce, should you consider trying U, V, and W? Which one(s) and why? Or if none of them, then why not?

You find that you have significantly overcharged one of your clients. The error was discovered when you received his cheque. It is unlikely that the customer or your company will become aware of the overcharge. Because of this error, the company realized a high net profit on the sale. Your commissions are based on this profit. What if anything, will you do about the overcharge?

Please include a brief explanation of your steps if you could, thank you!! TENSION MEMBERS Show all of your work for all calculations. Itemize from where in the AISC Manual or Specification you are getting your data and equations. This is important: it must be clear what you are doing and why. Use short statements to describe your work. Note: for calculations, always use the decimal tabulated dimensions of the sections, not their nominal or fractional dimensions. (30 pts.) For the truss from Homework #1, DESIGN the specified tension member P2 P2 P2 Wleft Wright b d 16 ft 4 10 12 ft g 11 P1 12 ft 12 ft DESIGN member 2 for tension for the following maximum factored force: Member # Maximum Factored Force (kips) 2 100.5 k Do not worry if the factored force does not match your answer in Homework 1. Design Criteria: Use A36 steel (F, = 36 ksi, F, = 58 ksi) Use the most economical LLBB double angles. Check the slenderness ratio (L/r) for both the double angles as a "built up” member, and also for the single angles that make up that member. If necessary, add intermediate fillers to shorten the unsupported length of the single angles until their slenderness is less than or equal to that of the built up member. Connection Details: Assume one row of 3/4” diameter A490 high strength steel bolts. Assume that there are at least 3 bolts in a row (along the length of the member). Assume the members are connected by a 3/8" thick gusset plate (A36 steel).

HANDS-ON ACTIVITY 2A Tracing Your Email Most email today is spam, unwanted commercial email, or phishing, fake email designed to separate you from your money. Criminals routinely send fake emails that try to get you to tell them your log-in information for your bank or your PayPal account, so they can steal the information, log-in as you, and steal your money. It is very easy to fake a return address on an email, so sim- ply looking to make sure that an email has a valid sender is not sufficient to ensure that the email was actually sent by the person or company that claims to have sent it. However, every SMTP email packet contains information in its header about who actually sent the email. You can read this infor- mation yourself, or you can use a tool designed to simplify the process for you. The objective of this Activity is for you to trace an email you have received to see if the sending address on the email is actually the organization that sent it. There are many tools you can use to trace your email. We like a tool called eMail Tracker Pro, which has a free version that lasts 15 days. 1. Go to www.emailtrackerpro.com and download and install eMail Tracker Pro. 2. Log-in to your email and find an email message you want to trace. I recently received an email supposedly from Wachovia Bank; the sender's email address was aw-login@wachovia.com. 3. Alter you open the email, find the option that enables you to view the Internet header or source of the mes- sage (in Microsoft Outlook, click the Options tab and look at the bottom of the box that pops up). Figure 2-19 shows the email I received and how to find the SMTP header (which Outlook calls the Internet header). Copy the entire SMTP header to the clip- board. 4. Start eMail Tracker Pro. Select Trace an email, and paste the SMTP header into the box provided. Click Trace to start the trace. 5. It may take up to 30 seconds to trace the email, so be patient. Figure 2-20 shows the results from the email I received. The email supposedly from Wachovia Bank was actually from a company named Musser and Kouri Law whose primary contact is Musser Ratliff, CPA, which uses SBC in Plano, Texas, as its Internet service provider. We suspect that someone broke into this company's network and used their email server without permission, or fraudulently used this com pany's name and contact information on its domain registration De Trace one email. Print the original email message and the trace results.

A flat puck (mass M ) is revolved in a circle on a frictionless air hockey table top, and is held in this orbit by a massless cord which is connected to a dangling mass (mass m ) through a central hole as shown in Fig. 5-46 . Show that the speed of the puck is given by $v=\sqrt{m g R / M}$ . FIGURE 5-46 Problem 68 .

The composite plate is made from both Steel (A) and brass (B) segments. Determine the mass and location (x, y, z) of its mass center G. Take rho_st = 7.85 Mg/m^3 and rho_br = 8.74 Mg/m^3.

The trial balance for Cullumber Fireplaces Inc. far December 31, 2024, follaws: 1. The deposits from customers were far future deliveries. As at December 31 , three-quarters of these goods had been delivered. 2. There is \( \$ 2,020 \) in wages awed at year end. 3. Rent is paid in advance on the las day of each month. There was a balance of \( \$ 3,040 \) The trial balance for Cullumber Fireplaces Inc. far December 31, 2024, follaws: 1. The deposits from customers were far future deliveries. As at December 31 , three-quarters of these goods had been delivered. 2. There is \( \$ 2,020 \) in wages awed at year end. 3. Rent is paid in advance on the las day of each month. There was a balance of \( \$ 3,040 \) in the Prepaid Rent account on January 1 , 2024. At the end of January, \$3,040 was paid for the February rent and was debited to the Prepaid Rent account. All the rent payments during the year were treated the same way. The rent for July to December increased to \( \$ 4,040 \) per month (Hint Determine the amount of rent expense for 2024 , as well as the correct amount that has been prepaid for 2025 , and make an adjustment that will bring bath these accounts to the carrect balances.) 4. A count of the supplies at year end revealed that \( \$ 510 \) of supplies were still on hand. 5. The building is being depreciated over 20 years with a residual value of \( \$ 20,200 \). 6. The bank loan was taken cut on Appril 1, 2024. The first interest payment is due an April 1, 2025. The interest rate is 10\%. 7. Income tax for the year should be calculated using a tax rate of \( 30 \% \). (Hint After you finish the other ad/usting entries, you will have to determine the income before income tax and then calculate the tax as \( 30 \% \) of this amaunt.] Prepare the adjusting entries for the year 2024.
