Answer:
well you find. out how many all of them measure. and add them and then that answer multiply of the main number
Step-by-step explanation:
first add up all of the lengths and then find that answer multiply it to the main number and then you will get your anwer it's a 2 step problem
Answer:
Step-by-step explanation:
![(\sqrt[4]{9})^{\frac{1}{2}x}=(9^{\frac{1}{4}})^{\frac{1}{2}x}\\\\=9^{\frac{1}{4}*\frac{1}{2}x}\\\\=9^{\frac{1}{8}x}](https://tex.z-dn.net/?f=%28%5Csqrt%5B4%5D%7B9%7D%29%5E%7B%5Cfrac%7B1%7D%7B2%7Dx%7D%3D%289%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D%29%5E%7B%5Cfrac%7B1%7D%7B2%7Dx%7D%5C%5C%5C%5C%3D9%5E%7B%5Cfrac%7B1%7D%7B4%7D%2A%5Cfrac%7B1%7D%7B2%7Dx%7D%5C%5C%5C%5C%3D9%5E%7B%5Cfrac%7B1%7D%7B8%7Dx%7D)
Answer:
since -3.73 is less than 1.645, we reject H₀.
Therefore this indicate that the proposed warranty should be modified
Step-by-step explanation:
Given that the data in the question;
p" = 13/20 = 0.65
Now the test hypothesis;
H₀ : p = 0.9
Hₐ : p < 0.9
Now lets determine the test statistic;
Z = (p" - p ) / √[p×(1-p)/n]
= (0.65 - 0.9) /√[0.9 × (1 - 0.9) / 20]
= -0.25 / √[0.9 × 0.1 / 20 ]
= -0.25 / √0.0045
= -0.25 / 0.067
= - 3.73
Now given that a = 0.05,
the critical value is Z(0.05) = 1.645 (form standard normal table)
Now since -3.73 is less than 1.645, we reject H₀.
Therefore this indicate that the proposed warranty should be modified
