For a given input value x, the function h outputs a value y to satisfy the following equation 6x+y=4x+11y. Write a formula for h
Tanzania [10]

Answer: h(x) = \frac{1}{5}x

<u>Step-by-step explanation:</u>

6x + y = 4x + 11y

<u>      -y </u>    <u>        -y  </u>

6x       = 4x + 10y

<u>-4x   </u>      <u>-4x         </u>

2x       =         10y

<u>÷10    </u>     <u>       ÷10 </u>

\frac{1}{5}x    =            y

Since "y" represents h(x), then h(x) = \frac{1}{5}x

garri49 [273]

Answer:

The degrees of freedom first given by:  

df=n-1=12-1=11  

Then we can find the critical value taking in count the degrees of freedom and the alternative hypothesis and then we need to find a critical value who accumulates 0.05 of the area in the right tail and we got:

t_{\alpha}= 1.796

And for this case the rejection region would be:

b) Reject H0 if tcalc >1.7960

Step-by-step explanation:

Information given

5, 7, 4, 6, 7, 5, 5, 6, 4, 4, 7, 5.

System of hypothesis

We want to test if the true mean is higher than 5, the system of hypothesis are :  

Null hypothesis:\mu \leq 5  

Alternative hypothesis:\mu > 5  

The statistic is given by:

t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}} (1)  

The degrees of freedom first given by:  

df=n-1=12-1=11  

Then we can find the critical value taking in count the degrees of freedom and the alternative hypothesis and then we need to find a critical value who accumulates 0.05 of the area in the right tail and we got:

t_{\alpha}= 1.796

And for this case the rejection region would be:

b) Reject H0 if tcalc >1.7960
