Use the following table:

Courses Credits Grade Computer Principles   4   D Business Law   2   F Logic   1   A Biology   2   C Marketing   4   D

A = 4, B = 3, C = 2, D = 1, F = 0

Calculate the grade-point average. (Round your answer to the nearest hundredth.) 

A business calculus course is designed with five grade categories: homework, Excel, exams, and final exam. Each category counts as a certain percent of the final course grade as shown in the table below. 

A student in the course has earned average scores in each category as given in the table.

(a) Find the number of points each category contributes toward the overall course grade.

Using the following table, calculate the stock's expected, and return the standard deviation and the coefficient of variation.

The table shows data collected on the relationship between the average daily temperature and coffee sales (in hundreds of dollars) at a coffee shop. The line of best fit for the data is ŷ =−0.68x+85.1. Assume the line of best fit is significant and there is a strong linear relationship between the variables.

According to the line of best fit, what would be the predicted number of coffee sales (in hundreds of dollars) for an average daily temperature of 32 degrees? Round your answer to two decimal places, as needed.
