Answer:

0.382

0.4

option (a)

Step-by-step explanation:

Formula to calculate probability

probability = number of times event occur / total number of trials

Experimental probability of landing on white = 191/500 = 0.382

probability = favourable outcome / total outcome

Theoretical probability of landing on white = 2/5 = 0.4

As more trials are conducted, the experimental probability generally gets closer to the theoretical probability.

A local artist creates a piece with two glass cylinders filled with colored water. The second cylinder has the same radius, but

KonstantinChe [14]

The formula for calculating volume of the cylinder is

V= B * H

First volume V1= B * H1 and second volume V2= B * H2

H1= 2 H2

when we divide V2/V1 = (B*H2)/(B*H1) => when we shorten B and B we get

V2/V1 = H2 / H1 when we replace H1 we get V2/V1 = H2/ 2H2

when we shorten H2 and H2 we get V2/V1 = 1/2

The correct answer is the volume of the second cylinder is one-half the volume of the first cylinder.

Good luck!!!

Sandra calculated the height of a cylinder that has a volume of 576 π cubic centimeters and a radios of 8 centimeters. Her work

Julli [10]

Answer:

$\boxed{Height \: of \: cylinder = 9 \: centimeters}$

Given:

Volume of cylinder = 576π cubic centimeters

Radius of cylinder (r) = 8 centimeters

Step-by-step explanation:

Let the height of cylinder be 'h'

$= > Volume \: of \: cylinder = \pi {r}^{2} h \\ \\ = > 576 \cancel{\pi} = \cancel{ \pi}( {8}^{2} )h \\ \\ = > 576 = 64h \\ \\ = > 64h = 576 \\ \\ = > h = \frac{576}{64} \\ \\ = > h = 9 \: centimeters$
