Distance = (rate)(time)
In this problem, note that both girls traveled the same distance.

Karens distance = r * 1.5 hrs          we dont know her rate
Nancy distance = 50 * 1 hr              we know she started 30 min later
                                                         but arrived at the same time

since the distances are equal
r*1.5 = 50 * 1          all you have to do is solve for r

1.5r = 50
r = 50/1.5
r = 33 1/3 miles per hour

The probability is 0.8997.

We will use a z-score to answer this question.  z-scores are given by the formula
z=\frac{X-\mu}{\sigma}

With our information, we have
z=\frac{622-590}{25}=\frac{32}{25}=1.28

Looking this up in a z-table (http://www.z-table.com) we see that the area to the left of this (everything less than, up to this value) is 0.8997.

Find the radius of the cylinder when volume is 304 cm^3 and height is 10 cm
aleksandr82 [10.1K]

Answer:

<h2>3.11 cm</h2>

solution,

Volume of cylinder=304 cm^3

height=10 cm

Radius=?

Now,

volume = \pi  {r}^{2} h \\ or \: 304 = 3.14 \times  {r}^{2}  \times 10 \\ or \: 304 = 31.4 \times  {r}^{2}  \\ or \:  {r}^{2}  =  \frac{304}{31.4}  \\ or \:  {r}^{2}  = 9.68 \\ or \: r =   \sqrt{9.68}  \\ or \: r =  \sqrt{ {(3.11)}^{2} }  \\ r = 3.11 \: cm

Hope this helps..

Good luck on your assignment..
