A sphere and a cylinder have the same radius and height. The volume of the cylinder is 27nft3. Which equation gives the volume o

inna [77]

Answer:

The volume of the sphere is $V=18\pi\ ft^{3}$

Step-by-step explanation:

we know that

The volume of cylinder is equal to

$V=\pi r^{2}h$

we have

$V=27\pi\ ft^{3}$

substitute

$27\pi=\pi r^{2}h$

simplify

$27=r^{2}h$

Remember that

A sphere and a cylinder have the same radius and height

The height of cylinder is equal to the diameter of sphere

h=2r

substitute

$27=r^{2}(2r)$

$13.5=r^{3}$ -----> equation A

The volume of the sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

substitute equation A in the formula of the volume of sphere

$V=\frac{4}{3}\pi (13.5)$

$V=18\pi\ ft^{3}$

An environmental science teacher at a high school with a large population of students wanted to estimate the proportion of stude

AnnZ [28]

Answer:

60 students

Step-by-step explanation:

The confidence interval of a proportion is given by:

$p\pm z*\sqrt{\frac{p*(1-p)}{n} }$

Where 'p' is the proportion of students who responded 'yes', 'z' is the z-score for a 95% confidence interval (which is known to be 1.960), and 'n' is the number of students in the sample.

If the confidence interval is from 0.584 to 0.816, then:

$p=\frac{0.584+0.816}{2}=0.7 \\0.816-0.584=2*(1.96*\sqrt{\frac{p*(1-p)}{n}}) \\0.116=1.96*\sqrt{\frac{0.7*(1-0.7)}{n}}\\n=16.8966^2*(0.7*0.3)\\n=60\ students$

60 students were in the sample.

Manuel has $600 in a savings account at the beginning of the summer. He wants to have at least $300 in the account at the end of

stiks02 [169]

The answer to this question is 600-28w > 300. This inequality can be described as $600 (money in the savings account) subtracted by $28w (withdrawal of $28 a week for food) should be greater than $300. It proves that the money will not drop below $300.
