A use case diagram shows how customers place orders without revealing internal system logic. Which statements are correct?

Why does Agile favor short iterations?

This test has a time limit of 40 minutes.This test consists of 13 multiple choice questions and 12 fill-in-the blank (code assignment) questions.Each question is worth 4 points.       Partial credit is provided for questions requiring two codes, however sequencing guidelines must be followed.This test will save and submit automatically when the time expires and/or when the due date/time have been reached.The timer will continue to run if you leave the test, so you should plan to take this test in one sitting.This test is due on April 27, 2026 11:59:00 PM EDT.The use of a secondary device (laptops, smartphones, smartwatches, tablets, etc.) is not allowed and considered a form of academic dishonesty and the consequences of doing so may result in a zero for a first offense and WF for repeated offenses. Honorlock flags students who are caught using a secondary device. Also prohibited are the following: notes, texts, online materials or other such unauthorized materials; For example, connecting with classmates by phone, email, Snapchat, GroupMe etc. while taking quizzes and tests.You are PERMITTED to use your ICD-10-CM 2026 Coding Manual. This is the ONLY resource that may be used. You may use blank scratch paper to write down code possibilities. 

One major criticism of Freud’s theory discussed in the text is that it:

Using course concepts from Modules 1–2, explain the role of prenatal care in healthy development before birth. In your answer, describe at least one possible complication that can occur when prenatal care is limited and connect it to a real-world example, current event, or personal experience. Be sure to clearly explain how your example relates to the course material.  (Partial credit is possible on this question).

Semiconductor lasers used in optical storage productsrequire higher power levels for write operations than for read operations.  High-power-level operations lower the useful life of the laser.  Lasers in products used for backup of higher-speed magnetic disks primarily write, and the probability that the useful life exceeds five years is 0.95. Lasers that are in products that are used for main storage spend approximately an equal amount of time reading and writing, and the probability that the useful life exceeds five years is 0.995. Now assume 25% of the products from a manufacturer are used for backup and 75% of the products are used for main storage.What is the probability that the useful life of a laser exceeds five years? What is the probability that a laser that failed before five years came from a product used for backup?

An ideal gas is compressed isothermally.  The change in entropy for this process is

A 1 kg block of ice at 0.00°C is thrown into a swimming pool at 22.0°C and melts (assume all the melted ice becomes water at exactly 0°C). If the pool remains at 22.0°C, calculate the change in entropy of the ice. Calculate the solution in J/K.  Type only the number part of the answer – do not include units.  Include negative signs where appropriate.   specific heats.JPGLatent Heat.JPG
