The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…

Chapter 8.2, Problem 44E

Assume that we are using simple interest to do the calculations in Exercises 41-44.

Borrowing from a bail bondsman. If a person accused of a crime does not have sufficient resources, he may have a bail bondsman post bail to be released until a trial is held. Assume that a bondsman charges a $50 fee plus 8% of the amount of the bail. If a bondsman posts $2 0 , 0 00 for a trial that takes place in 2 months, what is the interest rate being charged by the bondsman? (Treat the $50 fee plus the 8% as interest on a $2 0 , 0 00 loan for two months.)

Q3 (8 points) Q3. A survey classified a large number of adults according to whether they were diag- nosed as needing eyeglasses to correct their reading vision and whether they use eyeglasses when reading. The proportions falling into the four resulting categories are given in the following table: Use Eyeglasses for Reading Needs glasses Yes No Yes 0.44 0.14 No 0.02 0.40 If a single adult is selected from the large group, find the probabilities of the events defined below. The adult (a) needs glasses. (b) needs glasses but does not use them. (c) uses glasses whether the glasses are needed or not.
