A restaurant offers 20 appetizers and 40 main courses. In how many ways can a person order a two-course meal?

To calculate: The number of ways to order a two-course meal.
Answer to Problem 1RE
Solution:
The number of ways to order a two-course meal is
Explanation of Solution
Given:
Number of appetizers is 20, and the number of main courses is 40.
Formula used:
The Fundamental Counting Principle
If you can choose one item from a group of M items and a second item from a group of N items, then the total number of two-item choices is
Calculation:
The number of ways to order a two-course meal can be calculated by multiplying the given number of appetizers to the given number of the main courses.
Compute the number of ways to order two-course meal using the equation as shown below:

- The population mean and standard deviation are given below. Find the required probability and determine whether the given sample mean would be considered unusual. For a sample of n = 65, find the probability of a sample mean being greater than 225 if μ = 224 and σ = 3.5. For a sample of n = 65, the probability of a sample mean being greater than 225 if μ=224 and σ = 3.5 is 0.0102 (Round to four decimal places as needed.)arrow_forwarduestion 10 of 12 A Your answer is incorrect. L 0/1 E This problem concerns hybrid cars such as the Toyota Prius that are powered by a gas-engine, electric-motor combination, but can also function in Electric-Vehicle (EV) only mode. The figure below shows the velocity, v, of a 2010 Prius Plug-in Hybrid Prototype operating in normal hybrid mode and EV-only mode, respectively, while accelerating from a stoplight. 1 80 (mph) Normal hybrid- 40 EV-only t (sec) 5 15 25 Assume two identical cars, one running in normal hybrid mode and one running in EV-only mode, accelerate together in a straight path from a stoplight. Approximately how far apart are the cars after 15 seconds? Round your answer to the nearest integer. The cars are 1 feet apart after 15 seconds.
