Question

dolbears law states the relationship between the rate at which snowy tree crickets chirp and the air - temperature of their environment. the formula is t = 50+\frac{n - 40}{4}, where t is a temperature in degrees fahrenheit and n is a number of chips per minute. if n = 78, find the temperature in degrees fahrenheit, t. t = \square° (type an integer or a decimal.)

Explanation:

Step1: Substitute N value

Given the formula $T = 50+\frac{N - 40}{4}$ and $N = 78$. Substitute $N = 78$ into the formula: $T=50+\frac{78 - 40}{4}$.

Step2: Calculate the numerator

First, calculate the value in the numerator of the fraction: $78−40 = 38$. So the formula becomes $T = 50+\frac{38}{4}$.

Step3: Calculate the fraction value

Then, calculate $\frac{38}{4}=9.5$. So $T = 50 + 9.5$.

Step4: Calculate the final T value

Finally, add the two - values: $T=59.5$.

Answer:

$59.5$
