Using a number cube and this hat with 5 different-colored marbles, which simulation would help you answer this question? During
Arlecino [84]

Answer:

  see the attachment

Step-by-step explanation:

We assume that the question is interested in the probability that a randomly chosen class is a Friday class with a lab experiment (2/15). That is somewhat different from the probability that a lab experiment is conducted on a Friday (2/3).

Based on our assumption, we want to create a simulation that includes a 1/5 chance of the day being a Friday, along with a 2/3 chance that the class has a lab experiment on whatever day it is.

That simulation can consist of choosing 1 of 5 differently-colored marbles, and rolling a 6-sided die with 2/3 of the numbers being designated as representing a lab-experiment day. (The marble must be replaced and the marbles stirred for the next trial.) For our purpose, we can designate the yellow marble as "Friday", and numbers greater than 2 as "lab-experiment".

The simulation of 70 different choices of a random class is shown in the attachment.

<em>Comment on the question</em>

IMO, the use of <em>70 trials</em> is coincidentally the same number as the first <em>70 days</em> of school. The calendar is deterministic, so there will be exactly 14 Fridays in that period. If, in 70 draws, you get 16 yellow marbles, you cannot say, "the probability of a Friday is 16/70." You need to be very careful to properly state the question you're trying to answer.

Which point on the number line represents the approximate volume of a cone with the radius of 3 units and a height of 4 units? U
alekssr [168]

Answer: Third red dot after 30 on the number line represents the approximate volume of a cone.

Step-by-step explanation:

Since we have have given that

Radius of cone = 3 units

Height of cone = 4 units

So, Volume of cone is given by

Volume=\frac{1}{3}\pi^2\times h\\\\Volume=\frac{1}{3}\times 3.14\times 3\times 3\times 4\\\\Volume=37.68\ units^3

Hence, Third red dot after 30 on the number line represents the approximate volume of a cone.

I got this answer by doing 24.61/21.40 which equals 1.15

You can check this answer by doing 21.40 * .15 on a calculator and when you do this you get 3.21 which you can then add back to 21.40 to get $24.61
