Answer:
![h^{-1}(x) = \dfrac{5x - 6}{2}](https://tex.z-dn.net/?f=h%5E%7B-1%7D%28x%29%20%3D%20%5Cdfrac%7B5x%20-%206%7D%7B2%7D)
Step-by-step explanation:
![h(x)= \dfrac{2x + 6}{5}](https://tex.z-dn.net/?f=h%28x%29%3D%20%5Cdfrac%7B2x%20%2B%206%7D%7B5%7D)
(a) Rename h(x) as y
![y = \dfrac{ 2x+ 6}{5}](https://tex.z-dn.net/?f=y%20%3D%20%5Cdfrac%7B%202x%2B%206%7D%7B5%7D)
(b) Solve for x :
![\begin{array}{rcl}y& = &\dfrac{2x + 6}{5}\\\\5y & = & 2x + 6\\5y - 6 & = & 2x\\x & = & \mathbf{\dfrac{5y - 6}{2}}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Brcl%7Dy%26%20%3D%20%26%5Cdfrac%7B2x%20%2B%206%7D%7B5%7D%5C%5C%5C%5C5y%20%26%20%3D%20%26%202x%20%2B%206%5C%5C5y%20-%206%20%26%20%3D%20%26%202x%5C%5Cx%20%26%20%3D%20%26%20%5Cmathbf%7B%5Cdfrac%7B5y%20-%206%7D%7B2%7D%7D%5Cend%7Barray%7D)
(d) Switch x and y
![y = \dfrac{5x -6}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cdfrac%7B5x%20-6%7D%7B2%7D)
(e) Rename y as the inverse function
![h^{-1}(x) = \mathbf{\dfrac{5x - 6}{2}}](https://tex.z-dn.net/?f=h%5E%7B-1%7D%28x%29%20%3D%20%5Cmathbf%7B%5Cdfrac%7B5x%20-%206%7D%7B2%7D%7D)
The graphs of inverse functions are reflections of each other across the line y = x.
In the diagram, the graph of h⁻¹(x) is the reflection of h(x) about the line y = x.
Answer:
We reject the null hypothesis and accept the alternate hypothesis. Thus, it be concluded that the population mean is less than 20.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 60
Sample mean,
= 19.5
Sample size, n = 60
Alpha, α = 0.05
Population standard deviation, σ = 1.8
First, we design the null and the alternate hypothesis
We use One-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, it be concluded that the population mean is less than 20.
