Concept explainers

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

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 miles away.

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.

A biologist looked at the relationship between number of seeds a plant produces and the percent of those seeds that sprout. The results of the survey are shown below. Seeds Produced 63 62 43 43 58 59 67 61 Sprout Percent 55.1 62.4 64.1 74.1 63.6 66.3 51.9 64.7 Use the model to predict the percent of seeds that sprout if the plant produces 50 seeds.Percent sprouting = (Please round your answer to the nearest whole number.) Interpret the slope of the regression line in the context of the question: The slope has no practical meaning since it makes no sense to look at the percent of the seeds that sprout since you cannot have a negative number. As x goes up, y goes down. For every additional seed that a plant produces, the chance for each of the seeds to sprout tends to decrease by 0.55 percent. Interpret the y-intercept in the context of the question: The average sprouting percent is predicted to be 94.37. The best prediction for a plant that has 0 seeds is 94.37…
