Question

the table shows the number of minutes drew spends in each class for each of two weeks. assume that biology lab is the one class drew may or may not have on certain weeks, and that the duration of each class will only be one of the times shown in the table for any given week. complete parts (a) and (b)
(the question about the range is here, with table:
class | week 1 time (min) | week 2 time (min)
english | 60 | 60
math | 90 | 60
history | 45 | 45
biology | 45 | 45
biology lab | 0 | 60
what is the range? select the correct choice below, and fill in the answer box to complete your choice.
a. the range is {y | y = (type your answer(s) as whole numbers. use a comma to separate answers as needed) }
b. the range is {y | (type an inequality or a compound inequality) }

Explanation:

Step1: Find the minimum and maximum values

The minimum value of the data set (0,45,45,90,60,60,45,45,60,60) is \(0\), and the maximum value is \(90\).

Step2: Calculate the range

The range \(y\) is given by the formula \(y=\text{Max}-\text{Min}\). So \(y = 90 - 0=90\).

Answer:

A. The range is \(\{y|y = 90\}\)
