Answer:
There is enough statistical evidence to claim that the average length is not 10 cm.
Step-by-step explanation:
The claim that the average lenght is 10 cm, is the null hypothesis (has the "equal" sign). The claim that the average length is not 10 cm is the alternative hypothesis.
The significance level is assumed to be 0.10.
The sample mean is 7 cm and the sample standard deviation is 1 cm.
The degrees of freedom are
The t-statistic is:
The P-value of t=-30 is P=0.
This means there is almost no chance of getting this sample if the mean is really 10 cm.
There is enough statistical evidence to claim that the average length is not 10 cm.
The average rate of change of a function, g(x), over an interval [a, b] is given by
Thus, the average rate of change of
over the interval 
is given by:
![Average\ rate\ of\ change= \frac{[-(8)^2-4(8)]-[-(6)^2-4(6)]}{8-6} \\ \\ = \frac{(-64-32)-(-36-24)}{2} = \frac{-96-(-60)}{2} = \frac{-96+60}{2} = \frac{-36}{2} \\ \\ -18](https://tex.z-dn.net/?f=Average%5C%20rate%5C%20of%5C%20change%3D%20%5Cfrac%7B%5B-%288%29%5E2-4%288%29%5D-%5B-%286%29%5E2-4%286%29%5D%7D%7B8-6%7D%20%5C%5C%20%20%5C%5C%20%3D%20%5Cfrac%7B%28-64-32%29-%28-36-24%29%7D%7B2%7D%20%3D%20%5Cfrac%7B-96-%28-60%29%7D%7B2%7D%20%3D%20%5Cfrac%7B-96%2B60%7D%7B2%7D%20%3D%20%5Cfrac%7B-36%7D%7B2%7D%20%20%5C%5C%20%20%5C%5C%20-18)
Thus, the average rate of change of
8. To find the answer you can eather multipy it for each of the sides or you can add it 6 times once for each side
9. You basicly do the same thing as the previous problem but with the new numbers and you add each number 2 times
10. For are you multiply Base × Height So all you have to do is Multiply the 2 numbers shown together
11-12 Is the same but witb the new numbers
I hope this helps!
