a.
To construct: The table which represents x as minutes and y as no. of times the person breathes.
a.

Answer to Problem 12PPS
Explanation of Solution
Given information:
Person breathes 20 times per minute.
Formula:
No. of times person breathes=minutes
Consider the statement that Person breathes 20 times per minute.
Recall that No. of times person breathes=minutes
Therefore in
Therefore no. of times person breathes
No. of times person breathes
No. of times person breathes
No. of times person breathes
No. of times person breathes
Therefore the ordered pair table is
b.
To graph: To graph the
b.

Answer to Problem 12PPS
Explanation of Solution
Given information:
The ordered table is mentioned below.
Formula:
Use the ordered pair from the table mentioned above.
Graph:
The graph plotted below is a scatter plot on which minutes represents x axis and no. of times person breathes represents y axis.
Interpretation:
Considered the ordered pair of the table mentioned above.
Recall that x axis represents minutes and y axis represents no. of times person breathes.
Now we use the ordered pair table for the points to be plot.
Therefore we get the scatter plot as mentioned above.
c.
To write: An equation which relates the x and y where x represents minutes and y represents no. of times person breathes.
c.

Answer to Problem 12PPS
The algebraic equation relating x and y is
Explanation of Solution
Given information:
The ordered pair table is mentioned below.
Formula:
x represents minutes and y represents no. of times person breathes.
Consider the ordered pair table as mentioned above.
Recall that x represents minutes and y represents no. of times person breathes.
Therefore person breathes
Therefore

- A professor gives two types of quizzes, objective and recall. He plans to give at least 15 quizzes this quarter. The student preparation time for an objective quiz is 15 minutes and for a recall quiz 30 minutes. The professor would like a student to spend at least 5 hours total (300 minutes) preparing for these quizzes. It takes the professor 1 minute to grade an objective quiz, and 1.5 minutes to grade a recall type quiz. How many of each type of quiz should the professor give in order to minimize his grading time (why still meeting the other requirements outlined)?arrow_forwardTable 15-21 shows the relative frequencies of the scores of a group of students on a philosophy quiz.Table 15-21 Score45678 Relative frequency7%11%19%24%39%arrow_forwardInstructions: Answer each question showing all work. 1.

Convert the table from number 1 into a two-way relative frequency table. Instructions: Based on the tables created in questions 1 and 2 above, answer questions 3-7. 3. What percentage of cats from the total animals are vaccinated? 4. What is the relative frequency of dogs from the total animals that are not yet vaccinated? 5. What is the conditional frequency of cats that have not been vaccinated? 6. What is the marginal frequency of the total number of animals vaccinated? 7.
