英语翻译
Find a linear equation that models the temperature T as a function of the number of chirps per minute N.
请问T和N 谁是Y 谁是X
英语翻译Find a linear equation that models the temperature T as a function of the number of chirps per minute N.请问T和N 谁是Y 谁是X
写出函数:温度T随时间N(每分)变化.
所以一般来说T是Y,N是X

Biologists have noticed that the chirping rate of crickets of a certain species is related to temperature, and the relationship appears to be very nearly linear. A cricket produces 113 chirps per minute at 70°F and 173 chirps per minute at 80°F.
a. Find a linear equation that models the temperature T as a function of the number of chirps per minute N
b. what is the slope of this graph?
slope: (173-113) / (80-70) =
60 / 10 =
6
y=mx+b : m=6, pick any of the two points for x,y
113=(70)(6)+b
113=420+b
b= -307
y=6x-307 however it is not logical if the answer produces less than 0 chirps so....
0=6x-307
6x=307
x=51and1/6
now let x=T and y=N
N=6T-307 N>= 51and 1/6 degrees
他设的是T为x, N为y
题目是让你用一次等式表示温度T和每分钟蟋蟀声数量的关系
收起
找出一个线性方程,建立温度T随每分钟脉冲数量N变化的函数模型
T=f(N)
