Math HESI A2 Practice Test

1. What is the probability of rolling an even number on a six-sided die?

Correct answer: A

Rationale: The correct answer is A, 50%. A standard six-sided die has three even numbers (2, 4, 6) out of six possible outcomes. The probability of rolling an even number is therefore 3 out of 6, which simplifies to 50%. Choices B, C, and D are incorrect because they do not accurately reflect the probability of rolling an even number on a six-sided die.

2. The plane is due to land at 6:20 P.M. What would that be in military time?

Correct answer: B

Rationale: In military time, the afternoon and evening hours are represented by adding 12 to the standard time. Therefore, 6:20 P.M. would be equivalent to 18:20 in military time. To convert from P.M. to military time, simply add 12 hours to the given time. Choice A, '620,' is incorrect because it does not account for converting to military time. Choice C, '6020,' is incorrect as military time uses a 24-hour clock format, and the hour digit should not exceed 23. Choice D, '6200,' is incorrect as it does not follow the military time format where the hour part ranges from 00 to 23.

3. What is the primary function of the liver in the digestive system?

Correct answer: A

Rationale: The correct answer is A: 'To produce bile.' The liver's primary role in the digestive system is to produce bile. Bile is essential for emulsifying fats, aiding in their digestion and absorption in the small intestine. Choice B is incorrect because while the liver does secrete some digestive enzymes, its primary function is bile production. Choice C is incorrect because while the liver does store glucose, it is not its primary function in the digestive system. Choice D is incorrect because the liver produces bile, but it does not store it.

4. Which, if any, of the following statements about the biosphere is correct?

Correct answer: A

Rationale: Statement A is correct. The biosphere refers to the part of the Earth where life exists, including the land, water bodies, and atmosphere. It is the zone where living organisms and ecosystems exist. Statement B is incorrect because the biosphere covers various ecosystems on Earth but does not encompass the entire surface of the planet. The biosphere includes regions such as the lithosphere (land), hydrosphere (water bodies), and atmosphere, but not every part of the Earth's surface. Therefore, option C, stating both A and B are correct, is inaccurate. The correct answer is option A, as it accurately defines the biosphere.

5. How does the author want the reader to feel after reading about Bridge?

Correct answer: C

Rationale: The author wants the reader to feel confident and excited about learning the game of Bridge. In the text, the author acknowledges that Bridge can be complicated for beginners but emphasizes that with time, effort, and a good teacher, even novices can become proficient. The tone of the writing is encouraging and informative, providing tips and explanations to help the reader understand the game better and increase their interest in playing Bridge. Choices A, B, and D are incorrect because the text does not convey that the game is too hard for novices, aims to frustrate or confuse the reader, or overwhelm them with rules. Instead, the author's intention is to inspire confidence and excitement in learning this exciting card game.
