Step-by-step explanation:
Answer:
![4.91 in](https://tex.z-dn.net/?f=4.91%20in)
Step-by-step explanation:
a bucket has the form of a cylinder, which has the following formula for its volume:
![V=\pi r^2h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2h)
where r is the radius and h is the height.
Since we need to find the radius, we solve for r:
![r^2=\frac{V}{\pi h}\\ \\r=\sqrt{\frac{V}{\pi h} }](https://tex.z-dn.net/?f=r%5E2%3D%5Cfrac%7BV%7D%7B%5Cpi%20h%7D%5C%5C%20%5C%5Cr%3D%5Csqrt%7B%5Cfrac%7BV%7D%7B%5Cpi%20h%7D%20%7D)
and since we know according to the problem that:
![V=885in^3](https://tex.z-dn.net/?f=V%3D885in%5E3)
and
![h=11.7in](https://tex.z-dn.net/?f=h%3D11.7in)
substituing these values:
![r=\sqrt{\frac{885in^3}{(3.14)(11.7in)}}\\ \\r=\sqrt{\frac{885in^3}{36.738in}}\\\\r=\sqrt{24.0895in^2}\\\\r=4.908in](https://tex.z-dn.net/?f=r%3D%5Csqrt%7B%5Cfrac%7B885in%5E3%7D%7B%283.14%29%2811.7in%29%7D%7D%5C%5C%20%5C%5Cr%3D%5Csqrt%7B%5Cfrac%7B885in%5E3%7D%7B36.738in%7D%7D%5C%5C%5C%5Cr%3D%5Csqrt%7B24.0895in%5E2%7D%5C%5C%5C%5Cr%3D4.908in)
the radius is:
which can be rounded to ![4.91 in](https://tex.z-dn.net/?f=4.91%20in)
Answer:
Step-by-step explanation:
a) A test of H0: p = 0.6 vs. HA: p < 0.6 fails to reject the null hypothesis. Later it is discovered that p = 0.7.
Answer: No error has been made since there is not enough statistical evidence to reject the null.
b) A test of H0: μ = 30 vs. HA: μ > 30 rejects the null hypothesis. Later it is discovered that μ = 29.9.
A type I error has been made. Rejecting the null hypothesis when it is actually true.
c) A test of H0: p = 0.4 vs. HA: p /= 0.4 rejects the null hypothesis. Later it is discovered that p = 0.55.
A type I error has been made since the p value was greater than 0.4, one will fail to reject the null but in the case the null was rejected.
d) A test of H0: p = 0.7 vs. HA: p < 0.7 fails to reject the null hypothesis. Later it is discovered that p = 0.6.
A type II error has been made since the p value is less than 0.7 and it was expected that the null should be rejected but that ws not the case.
Answer:
D. w < 3.3
Step-by-step explanation:
It cannot be A because a book is 2.3 pounds. (w > 2.3) it would be correct if it was (w ≥ 2.3)
It cannot be B because majority of the books has a greater mass than 2.4 pounds. (w < 2.4)
It cannot be C because all books have a lesser mass(or equal mass) than 3.2 pounds (w > 3.2)
It is D because W is less than 3.3 pounds ( w < 3.3)
The answer is when time started it was 5 feet. I took the test and that was right for me
