Find the inverse function for y=3/4+x
Sonja [21]

The inverse of this function is y = x - \frac{3}{4}


You can find the inverse of any function by switching the x and y values and then solving for the new y value. Once you've done that, what will be left over is the inverse function.


y = \frac{3}{4} + x ----> Swap x and y

x = \frac{3}{4} + x -----> Subtract 3/4 from both sides.

x - \frac{3}{4} = y ----> rearrange to appropriate order

y = x - \frac{3}{4}


And that is your inverse function.

We have a null hypothesis that u=3.75, but we are reluctant to accept this as the population value in case the true value is dif
Gala2k [10]

Answer:

option A

Step-by-step explanation:

To Test

H₀ : μ = 3.75            

H₁ : μ ≠ 3.75                

now,                                        

If μ = 3.95 then it means H₀ is not true.                  

then the probability is rejecting the null hypothesis.        

Hence, the probability is the power of the test against the alternative μ=3.95                      

The correct answer is option A
