(a) Find the linear equation that relates the temperature t and the number of chirps per minute n.
If the equation is linear, then the equation should have the form of t = mn + b
m = (80 - 70) / (168 - 120) = 5/24
t = 5/24n + b
70 = 5/24(120) + b
b = 45
t = 5/24 n + 45
<span>(b) If the crickets are chirping at 138 chirps per minute, estimate the temperature. (Round your answer to the nearest degree.)
</span><span>t = 5/24 n + 45
</span><span>t = 5/24 (138) + 45 = 74 </span>°F
I used Desmos Graphing Calculator. Helps so much!
Hope this helps!
Answer:
what are the options?
Step-by-step explanation:
Answer:
t = 2n + 3
Step-by-step explanation:
Given
4n = 2(t - 3) ← divide both sides by 2
2n = t - 3 ( add 3 to both sides )
2n + 3 = t
