ivann1987 [24]

Answer:

Even numbers are 2,4,6 for this case and the experimental probability of being even is given by:

p = \frac{30+25+17}{120}= \frac{72}{120}= 0.6

Now we can find the theorical probability since we have 6 possible outcomes 2, 2, 3, 4, 5, and 6 we have 4 even numbers in the sample space and the theorical probability is given by:

p= \frac{4}{6}= 0.667

Then we can conclude that the empirical probability is lower than the theorical probability (0.6<0.667)  for this experiment

Step-by-step explanation:

For this case we wan find the probability associated to the experiment we know that. The pointer lands 30 times on a section numbered 2, 19 times on 3, 25 times on 4, 29 times on 5, and 17 times on 6.

Even numbers are 2,4,6 for this case and the experimental probability of being even is given by:

p = \frac{30+25+17}{120}= \frac{72}{120}= 0.6

Now we can find the theorical probability since we have 6 possible outcomes 2, 2, 3, 4, 5, and 6 we have 4 even numbers in the sample space and the theorical probability is given by:

p= \frac{4}{6}= 0.667

Then we can conclude that the empirical probability is lower than the theorical probability (0.6<0.667)  for this experiment

What is the volume of the figure?
serious [3.7K]

Answer:

188 ft^{3}

Step-by-step explanation:

So we can split up this shape into two prisms and then add the two areas.

The volume of a rectangular prism is V = l*w*h

For the first prism, we have our length as 3, our width as 4, and our height as 9. Substituting these values into our volume equation gives us V = (3)(4)(9) = 108 ft^{3}.

Now for the second prism, we have our length as 5, our width as 4, and our height as 4. Substituting these values into our volume equation give us V = (5)(4)(4) = 80 ft^{3}

Now adding these two values will give us the area of the entire figure: 108ft^{3} +80ft^{3} = 188 ft^{3}
