Chirps and Temperature Relationships

The video tutorial explains how the number of chirps per minute by tree crickets is linearly dependent on temperature in Fahrenheit. It starts by establishing the relationship using ordered pairs and derives a linear equation in slope-intercept form. The tutorial then calculates the slope and intercept, and applies the equation to determine the number of chirps at a given temperature, specifically at 60 degrees Fahrenheit.

What is the relationship between the number of chirps per minute and temperature?

• Linear

• Logarithmic

• Exponential

• Quadratic

At what temperature do crickets start chirping according to the given data?

• 60 degrees Fahrenheit

• 50 degrees Fahrenheit

• 40 degrees Fahrenheit

• 30 degrees Fahrenheit

What is the ordered pair for 50 degrees and 42 chirps per minute?

• (50, 42)

• (42, 50)

• (50, 0)

• (0, 42)

What is the formula for a linear equation in slope-intercept form?

• y = ax^2 + bx + c

• y = mx + b

• y = log(x)

• y = a^x

How do you calculate the slope between two points?

• Divide the change in y by the change in x

• Add the change in x and y

• Divide the change in x by the change in y

• Multiply the change in y by the change in x

What is the slope of the line relating chirps to temperature?

• 6.1

• 3.5

• 4.2

• 5.0

What is the y-intercept of the equation derived?

• -168

• 0

• 168

• 42

What is the equation for chirps in terms of temperature?

• c = t - 168

• c = 4.2t

• c = 4.2t + 168

• c = 4.2t - 168

How many chirps per minute are expected at 60 degrees?

• 108

• 72

• 84

• 96

What unit is used for the number of chirps?

• Chirps per hour
