Nonvoters are less affluent and less educated. Nearly half of nonvoters (46%) have family incomes less than $30,000, compared with 19% of likely voters. Most nonvoters (54%) have not attended college; 72% of likely voters have completed at least some college (Source: Pew Research Center, October, 2014, "The Party of Nonvoters"). Suppose you interview 12 people who are considered nonvoters. Round answers to 4 decimal places.a.) What is the probability that 12 nonvoters have a family income of less than $30,000? b.) What is the probability that more than 8 nonvoters have a family income of less than $30,000 ? c.) What is the probability that at least 8 nonvoters have not attended college? d.) What is the probability that fewer than 12 nonvoters have not attended college?
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.
