A biology student is investigating the claim that the temperature can be predicted by counting cricket chirps. She has found a linear regression equation T=42.2+0.21r
where T is the temperature in degrees Fahrenheit and r is the number of chirps per minute. What is the predicted temperature for 90 chirps per minute?(1 point)

The predicted temperature for 90 chirps per minute can be calculated using the regression equation T=42.2+0.21r:
T = 42.2 + 0.21(90)
T = 42.2 + 18.9
T = 61.1°F
Therefore, the predicted temperature for 90 chirps per minute is 61.1°F.
