a) The analysts’ stock recommendations are of considerable interest to investors.

A sell recommendation is ‘successful’ if the stock underperforms the benchmark by at least 2% over the next year. (iii) What is the probability that a chosen recommendation is either a new buy or successful?
Unitary Method
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

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 experiments to set up the devices.
