Null Hypothesis: The proportion of clients satisfied at the downtown office is greater than the proportion of clients satisfied at the uptown office.

Alternative Hypothesis: Downtown clients are less satisfied with the dental office staff than uptown clients.

Null Hypothesis: The proportion of clients satisfied at the downtown office is 84%.

Alternative Hypothesis: Uptown clients are more satisfied with the dental office staff than downtown clients.

Null Hypothesis: The proportion of clients satisfied at the downtown office is equal to the proportion of clients satisfied at the uptown office.

My number is a perfect square the only prime number in its prime factorization is 2

Semenov [28]

I think the number would be 256 because

256 :
128*2
64*2
32*2
16*2
8*2
4*2
2*2

secondly if u divide 256 by 32 it gives 8 so it's a factor of 32

and lastly 2+5+6 = 13 which is an odd number

hope this helps!

A cylindrical base has a diameter of 6 inches. At the bottom of the vase, there are 9 marbles, each of the diameter 3 inches. Th

alexandr1967 [171]

Answer:

$\sf C. \quad \pi (3\:in)^2(12\:in)-9 \left(\dfrac{4}{3} \pi (1.5\:in)^3 \right)$

Step-by-step explanation:

To find the volume of water in the vase, subtract the volume of the marbles from the volume of the cylindrical vase.

..............................................................................................................................

The marbles can be modeled as <u>spheres</u>.

<u>Volume of a sphere</u>

$\sf V=\dfrac{4}{3}\pi r^3 \quad \textsf{(where r is the radius)}$

<u>Radius</u>

$\sf r = \dfrac{1}{2}d \quad \textsf{(where d is the diameter)}$

Therefore, the volume of 9 marbles, each of diameter 3 inches is:

$\sf Volume & = \sf 9 \left(\dfrac{4}{3} \pi (1.5\:in)^3 \right)$

..............................................................................................................................

The vase can be modeled as a <u>cylinder</u>.

<u>Volume of a cylinder</u>

$\sf V=\pi r^2 h \quad \textsf{(where r is the radius and h is the height)}$

Therefore, the volume of a cylinder with a base of diameter 6 in and a height of 12 in is:

$\sf Volume =\pi (3\:in)^2(12\:in)$

..............................................................................................................................

<u>Volume of water</u>

<u />

$\begin{aligned}\implies \sf Volume\:of\:water & = \sf Volume\:of\:vase- Volume\:of\:marbles\\& = \sf \pi (3\:in)^2(12\:in)-9 \left(\dfrac{4}{3} \pi (1.5\:in)^3 \right)\end{aligned}$
