Homework Help Overview

The discussion revolves around translating a word problem involving the relationship between temperature and the number of chirps per minute into a mathematical equation. The context is linear relationships in a real-world scenario, specifically relating to chirping rates of crickets or similar creatures at different temperatures.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the reasoning behind placing temperature and chirps in specific positions when calculating slope. There is a discussion about whether chirps or temperature should be considered the dependent variable.

Discussion Status

Some participants have provided insights into the phrasing of the problem and its implications for determining the dependent and independent variables. There is an acknowledgment of the need for clarity regarding the original question posed in the homework.

Contextual Notes

There is a mention of a missing question from the original problem statement that could provide further clarity. Additionally, some participants express confusion about the term "chirp," indicating a potential gap in understanding the context of the problem.

Homework Statement


We know relationship between temp and number of chirps per minute is linear. 113 chirps per minute at a 70degrees F. 173 chirps per minute at 80 degrees F.


Homework Equations


In this problem why do we put degrees on top of chirps in finding the slope.


The Attempt at a Solution


I understand that it would be 80-70/(173-113) because my original answer didnt seem right. I am just curious as to how to know logically through the problem that I would put the chirps on bottom not on top to begin with

Technically you could do it either way. In this problem, the way it is phrased, it says when the temp is 70 you get 113 cpm and when the temp is 80 you get 173 cpm. So it is suggesting that chirps/minute is a function of temperature. That would suggest temperature is the dependent variable.

The real answer to your question may be in the statement of the problem where it asks you to calculate something. You never stated the question that you were asked to solve in part 1 of the homework template. If I knew that I might be able to give a better answer.

What's a chirp?

Oops, LKC beat me to it...
 
Thank you lkc. You are right, in the question it says right a function that models temp t as a function of chirps per minute N. Thank you.

No birds or crickets where you live?

You, of all people, should know. It's a cw signal when the frequency isn't stable. :cool:
