Math HESI A2 Practice Test
1. What is the result of dividing 3.44 by 0.6?
- A. 11.41
- B. 5.73
- C. 2.33
- D. 0.57
Correct answer: B
Rationale: The correct answer is B: 5.73. When dividing 3.44 by 0.6, the calculation is 3.44 รท 0.6 = 5.73. Choice A (11.41) is incorrect because it is the result of multiplying, not dividing. Choice C (2.33) and Choice D (0.57) are also incorrect results obtained by incorrect calculations.
2. A set of temperature readings has a range of 5 degrees Celsius. What does this tell you about the data?
- A. The average temperature is 5 degrees Celsius.
- B. All temperatures are within 5 degrees of each other.
- C. The difference between the highest and lowest temperatures is 5 degrees.
- D. There are exactly 5 temperatures in the set.
Correct answer: C
Rationale: Option A is incorrect because the range of 5 degrees does not necessarily mean that the average temperature is 5 degrees Celsius. The average temperature could be any value within the range. Option B is incorrect because the range of 5 degrees does not mean that all temperatures are within 5 degrees of each other. It only indicates the difference between the highest and lowest temperatures. Option C is correct because the range of 5 degrees specifically refers to the difference between the highest and lowest temperatures in the set. This is a common definition of range in statistics. Option D is incorrect because the range of 5 degrees does not determine the number of temperatures in the set. The set could have more or fewer than 5 temperatures.
3. The development of the disease was INSIDIOUS.
- A. Momentous
- B. Sudden
- C. Innocuous
- D. Gradual
Correct answer: D
Rationale: The term 'insidious' typically describes something that occurs gradually and subtly, often without being noticed until it has become more serious or established. Therefore, the development of the disease being insidious suggests that it was gradual, aligning best with the meaning of the word in this context. Choice A, 'momentous,' means significant or important, which is opposite in meaning to insidious. Choice B, 'sudden,' indicates something happening quickly and unexpectedly, contrary to the gradual nature of an insidious development. Choice C, 'innocuous,' means harmless or not likely to cause harm, which does not accurately reflect the negative and harmful connotation associated with an insidious disease development.
4. In the following sentence, which word or phrase is the subject: 'The nurses went to the conference room.'
- A. conference
- B. went to
- C. room
- D. nurses
Correct answer: D
Rationale: In the sentence, 'The nurses went to the conference room,' 'nurses' is the subject. The subject of a sentence is typically the noun or pronoun that carries out the action or is described in the sentence. In this case, 'nurses' is the noun performing the action of going to the conference room. Choices A, B, and C are not the subject. 'Conference' and 'room' are objects of the prepositions 'to' and 'the,' while 'went to' is the verb phrase indicating the action performed by the subject.
5. Why was the roadway so dangerous to build?
- A. There weren't enough materials available to build the road
- B. The workers might get hit by passing cars
- C. The men would fall to their deaths
- D. The men would be attacked by animals.
Correct answer: C
Rationale: The roadway was dangerous to build because the men involved in the construction were at risk of falling to their deaths. The excerpt mentions that the construction of the roadway was the most dangerous and treacherous part of the entire task, indicating a high risk of falling due to the height and precarious nature of the construction site. Choice A is incorrect because the danger was due to the physical risks of falling and not due to a lack of materials. Choice B is incorrect as passing cars were not the primary danger during the construction of the roadway. Choice D is incorrect since there is no mention of workers being attacked by animals during the construction of the Golden Gate Bridge.
