Answer:
8 inches
Step-by-step explanation:
Given: Dimension of rectangular container=
Water is filled up to a level 2 inches from the top.
As given that container is sitting on its largest face, then it is standing on
Which means the height of container is 6 inches and it ie filled with water up to 2 inches from the top.
∴ Height of water inside the container=
Now, finding the volume of water inside.
we know, Volume=
Volume=
Next, if container is placed in its smallest face then it is standing on and lets assume height to be "x"
Forming an equation now to express the volume conservation law.
⇒
⇒
dividing both side by 60
⇒
∴ x= 8 inches
Hence, 8 inches from the bottom will the water level reach if the container is placed on its smallest face
Answer:
Step-by-step explanation:
According to the empirical rule, the 95% confidence interval for the true population proportion is given by :-
Given : . The survey resulted in a sample proportion of p′=0.14, with a sampling standard deviation of σp′=0.02, who preferred reading an e-book.
Then, the 95% confidence interval for the true proportion of adults who prefer e-books will be :-
Hence, the 95% confidence interval for the true proportion of adults who prefer e-books=
Answer:
and
Step-by-step explanation:
The null hypothesis states that a population parameter (such as the mean, the standard deviation, and so on) is equal to a hypothesized value. We can write the null hypothesis in the form
In this context, the investigator's null hypothesis should be that the average total weight is no different than the reported value by the FAA. We can write it in this form .
The alternative hypothesis states that a population parameter is smaller, greater, or different than the hypothesized value in the null hypothesis. We can write the alternative hypothesis in one of three forms
The investigator wants to know if the average weight of passengers flying on small planes exceeds the FAA guideline of the average total weight of 185 pounds. He should use as his alternative hypothesis.
