An unstable nucleus with a mass of 16.3 × 10−27 kg initially at rest disintegrates into three particles. One of the particles, of mass 4.9 × 10−27 kg, moves along the positive yaxis with a speed of 4.5 × 106 m/s. Another particle, of mass 8.7 × 10−27 kg, moves along the positive x-axis with a speed of 3.4 × 106 m/s.

a) Find the speed of the third particle. Answer in units of m/s.

b) At what angle does the third particle move?

You will invest the following cash flows into an investment account on the following dates.

TIME CASH FLOWS --------------------------------------------------------------

1/1/23 +$6500

1/1/24 +$6500

1/1/25 +$6500

1/1/26 +$6500

1/1/27 +$6500

Assume an interest rate of 10%, compounded annually. (The stated rate is 10%, compounded annually.) How much will you have in your account on 1/1/27 the instant after you make that last investment of $6500 on 1/1/27?

During June, the following changes in inventory item 27 took place:

Perpetual inventories are maintained.

a. What is the cost of the ending inventory for item 27 under the FIFO method?

b. What is the cost of the ending inventory for item 27 under the LIFO method?

Perpetual Inventory Using LIFO

Beginning inventory, purchases, and sales for Item 88-HX are as follows:

Assuming a perpetual inventory system and using the last-in, first-out (LIFO) method, determine (a) the cost of goods sold on Mar. 27 and (b) the inventory on Mar. 31.

The following data give the number of hours 5 5 students spent studying and their corresponding grades on their midterm exams. Hours Studying   Midterm Grades

A statistics instructor wonders whether significant differences exist in her students’ final exam scores in her three different sections. She randomly selects the scores from 10 students in each section. A portion of the data is shown in the accompanying table. Assume exam scores are normally distributed.

Construct an ANOVA table. (Round "Sum Sq" and "Mean Sq" to 1 decimal place, "F value" to 3, and "p-value" to 3 decimal places. Before fitting your model, type options(scipen=10) and options(digits=10) into your R console.)
