Answer:
The cricket make approximately 3 chirps in 15 seconds if the temperature is 80°F.
Step-by-step explanation:
We are given the following in the question:
[tex]y = 15x + 37[/tex]
The above equation is used approximate the temperature y in degrees Fahrenheit based on the number of chirps x a cricket makes in 15 seconds.
The attached image shows the graph for the given equation.
Now, we have to find the number of chirps a cricket will make in 15 seconds if the temperature is 80°F.
Putting y = 80 in the given equation, we get:
[tex]y = 15x + 37\\80 = 15x+37\\15x = 80-37\\15x = 43\\x = 2.8667 \approx 3[/tex]
Thus, the cricket make approximately 3 chirps in 15 seconds if the temperature is 80°F.
