Yes. The graph is bell-shaped and roughly symmetric. b. No. The graph is skewed to the left the distribution of values is not very close in following the 68-95-99.7 rule for a normal distribution. c. Yes. While the graph is skewed to the left, the distribution of values is very close in following the 68-95-99.7 rule for a normal distribution, d. There is not enough information to determine if the distribution of these values is approximately normal. a. seJ Aoanba

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.

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.
