The statement which best explains how algorithms running on a computer can be used to solve problems is; D. Some problems cannot be solved by an algorithm.
<h3>What is an algorithm?</h3>
An algorithm is simply a standard formula or procedures which is made up of a set of finite steps and instructions that must be executed on a computer, so as to proffer solutions to a problem or solve a problem under appropriate conditions.
However, it should be noted that it is not all problems that can be solved by an algorithm, especially because the required parameters and appropriate conditions are not feasible or met.

Without middleware, different BI programs cannot easily connect to the data warehouse: True.
<h3>What is a data warehouse?</h3>
A data warehouse can be defined as a logical collection of information that are gathered or obtained from many different operational databases, in order to both support and enhance day-to-day business analysis activities and decision-making tasks of various employees who are working in a business organization.
This ultimately implies that the primary purpose of a data warehouse is to logically aggregate a collection of information from all the departments in a business organization into a single repository.
However, we can infer and logically deduce that without middleware such as application server, different Business intelligence (BI) programs won't easily connect to the data warehouse.
