A box contains 500 marbles. The result of 20 marbles pulled at random from the box is given below.

Anni [7]

Answer:

100 black marbles

Step-by-step explanation:

The experimental probability of a black marble is

P(black) = 4/20 = 1/5

We expect that out of the 500 marbles in the box, 1/5 of them are black

1/5 (500) = 100

There should be 100 black marbles

vodka [1.7K]

3 days. If every day he runs 10 laps then that would be 4000 meters. 1 kilometer is equal to 1000 meters. That means everyday he runs 4 kilometers. Then after 3 days he would have ran 12 kilometers.

Answer:

(1) 23.55mm³

(2) 340.17in³

Step-by-step explanation:

Volume of a cone is: $V=\frac{1}{3} \pi r^2h$

'r' - radius

'h' - height

The height of Cone 1 is 10 mm. The Diameter of Cone 1 is 3mm.

Radius is half the Diameter.

$3/2=1.5$

The radius is 1.5 mm.

$\text {Using 3.14 as pi: }\\V=(1/3)3.14*1.5^2*10\\V=(1/3)3.14*2.25*10\\V=(1/3)70.65\\\boxed{V=23.55}$

The volume of Cone 1 should be about 23.55mm³.

The height of Cone 2 is 13 in. The Radius of Cone 2 is 5 in.

Using 3.14 as pi:

$V=(1/3)3.14*5^2*13\\V=(1/3)3.14*25*13\\V=(1/3)1020.5\\\boxed {V=340.166666667}$

340.166666667 ≈ 340.17

The volume of Cone 2 should be about 340.17in³.
