A rigid, insulated tank that is initially evacuated is connected through a valve to a supply line that carries steam at 1 MPa and 300°C. Now the valve is opened, and steam is allowed to flow slowly into the tank until the pressure reaches 1 MPa, at which point the valve is closed. Determine the final temperature of the steam in the tank.

The child may have their own version of some of the work they may have, while the teacher only has most of the notes and the grading

Z is between 1.37 and 1.75? d. Z is less than 1.67 or greater than 1.78? 6.5 Given a normal distribution with ? = 90 and ? = 10, what is the probability that a. X > 65? b. X < 60? c. X < 70 or X > 110? 7.1 Given a normal distribution with ? = 100 and ? = 10, if you select a sample of n = 25, what is the probability that X is a. less than 95? b. between 95 and 97.5? c. above 102.2? d. There is a 65% chance that X is above what value? For a standardized normal distribution, determine a value, say z0, so that P(- z0 ? z ? 0) = 0.45. Round to two decimal places as needed. Which of the following is not a characteristic of the normal distribution? A. Mean = median = mode B. Bell-shaped C. Equal positive probabilities at all values of x D.

Prepare 2017 entries for Concord assuming that the warranties are not an integral part of the sale (a service-type warranty). Assume that of the sales total, $55,000 relates to sales of warranty contracts. Concord estimates the total cost of servicing the warranties will be $54,000 for 2 years. Estimate revenues to be recognized on a straight-line basis. (If no entry is required, select \"No Entry\" for the account titles and enter 0 for the amounts. Credit account titles are automatically indented when amount is entered. Do not indent manually. Round intermediate calculations to 5 decimal places, e.g. 1.54657 answers to O decimal places, e.g. 5,125.) Date Account Titles and Explanation Debit Credit ? At Sale Cash ? 3660000 ?
