Step-by-step explanation:
Hello!
The population variance is symbolized σ² and the standard deviation σ (remember that for estimations and statistics test, the parameter of study is always the variance)
The sentence "The standard deviation of pulse rates of adult males is less than 12 bpm." is symbolized σ <12
The sample variance is symbolized S² and the standard deviation is S.
The sample standard deviation is S= 11.5.
I hope it helps!
Answer:
Step-by-step explanation:
Note that the cost function is
, which gives us the cost of electricity for x hours of consumption
a). The function ![c^{-1}(x)[tex] which is the inverse function, tells us given a cost, the amount of hours we can consume electricty. b) Consider the equation [tex]y=7.1+23\ln(x)](https://tex.z-dn.net/?f=c%5E%7B-1%7D%28x%29%5Btex%5D%20which%20is%20the%20inverse%20function%2C%20tells%20us%20given%20a%20cost%2C%20the%20amount%20of%20hours%20we%20can%20consume%20electricty.%20%3C%2Fp%3E%3Cp%3Eb%29%20Consider%20the%20equation%20%3C%2Fp%3E%3Cp%3E%5Btex%5Dy%3D7.1%2B23%5Cln%28x%29)
To find out the inverse function, we interchange the labels of x and y and solve for y, that is
when solved for y we have

So the inverse function is given by
.
c) We will use the inverse function to find the amount of hours the customer can use eelectricity. It is simple obtained by evaluating the inverse function at the desired cost (i.e
)
that is

that is, the custome can consume at most 1.41 hours of electricity.
