Biologists have noticed that the chirping of crickets of a certain species is related to temperature, and the relationship appears to be very nearly linear. A cricket produces 119 chirps per minute at 67 degrees Fahrenheit and 172 chirps per minute at 88 degrees Fahrenheit. Find a linear equation that models the temperature as a function of the number of chirps per minute .

If the crickets are chirping at 152 chirps per minute, estimate the temperature:
Temperature =

hirps = 119 + (172-119)(T-67)/(88-67)

To find a linear equation that models the temperature as a function of the number of chirps per minute, we can use the two data points provided and apply the slope-intercept form of a linear equation, y = mx + b.

Let's label the temperature as "T" and the chirps per minute as "C". We are given two sets of data:

At 67 degrees Fahrenheit, the cricket produces 119 chirps per minute, which we can write as (67, 119).
At 88 degrees Fahrenheit, the cricket produces 172 chirps per minute, which we can write as (88, 172).

To find the slope (m) of the linear equation, we can use the formula:

m = (y2 - y1) / (x2 - x1)

Plugging in the values, we get:

m = (172 - 119) / (88 - 67)
= 53 / 21
= 2.5238

Now, we can use the slope-intercept form and one of the points to find the y-intercept (b). Let's use the first data point (67, 119):

119 = 2.5238 * 67 + b
119 = 169.4856 + b

b = 119 - 169.4856
b = -50.4856

Therefore, the linear equation that models the temperature as a function of the number of chirps per minute is:

T = 2.5238C - 50.4856

Now, to estimate the temperature when the crickets are chirping at 152 chirps per minute, we can substitute C = 152 into the equation:

T = 2.5238 * 152 - 50.4856
T = 383.6976 - 50.4856
T = 333.212

Therefore, the estimated temperature when the crickets are chirping at 152 chirps per minute is approximately 333.212 degrees Fahrenheit.
