Biology The number of times a cricket chirps per minute depends on the temperature. The number of chirps in 2 seconds for two temperatures are shown below.
What graph models the situation?
First, find the number of chirps per minute.
Let x = temperature in degrees Fahrenheit.
Let y = number of times a cricket chirps.
Plot (40,0) and (93, 240).
Draw a line through the points.
How can you find the number of chirps in a minute given the number of chirps in 2 seconds?
There are 60 seconds in 1 minute. Multiply the number of chirps in 2 seconds by
What is an equation of the line in standard form?
If the temperature is 70°F, how many times would a cricket be expected to chirp in one minute?
Let
If the temperature is 70°F, the cricket would be expected to chirp 135 times in one minute.
