Probability theory predicts that there is a 22.4% chance of a particular soccer player making four penalty shots in a row. If the soccer player taking four penalty shots is simulated 2500 times, in about how many of the simulations would you expect at least one missed shot?

Answers

If there is a 22.4% chance that a soccer player will make 4 shots in a row, then the probability that he/she WON'T make 4 shots in a row is...

100 -22.4 = 77.6%

So the number of simulations that he/she will miss at least one shot in 2500 simulations would be...

2500 x 77.6% =
2500 x .776 = 1940

If a woman who has a mass of 115 lb, what is her mass in grams?

Answers

Answer:

Her mass is approximately 52,134.99 grams.

Step-by-step explanation:

To convert a mass from pounds (lb) to grams (g), you can use the following conversion factor:

1 lb = 453.59237 g

So, to find the mass of a woman who weighs 115 lb in grams:

Mass (in g) = 115 lb * 453.59237 g/lb = 52,134.98955 g

Therefore, her mass is approximately 52,134.99 grams.

Brooks built two similar wooden chests in the shape of rectangular prisms. She used 16 pints of paint to cover the outside of the larger chest fully and 9 pints to cover the outside of the smaller chest. What is the ratio of the volume of the larger chest compared to the smaller chest?

Answers

Choices: A. 16/9 B. 4/3 C. 32/9 D. 64/27

Given:
number of pints used for larger chest = 16 pints
number of pints used for smaller chest = 9 pints

Ratio of the volume of the larger chest compared to the smaller chest.

We will use the number of pints used in lieu of the volume of each chest.

16 / 9 is the ratio. Choice A.
