TEAS Math Questions
1. If you pull an orange block from a bag of 3 orange, 5 green, and 4 purple blocks, what is the probability of consecutively pulling two more orange blocks without replacement?
- A. 1/12
- B. 3/55
- C. 1/55
- D. 2/33
Correct answer: B
Rationale: To calculate the probability of pulling two more orange blocks consecutively without replacement after the initial orange block is pulled, we need to multiply the probabilities. After the first orange block is pulled, there are 2 orange blocks left out of a total of 11 blocks remaining. So, the probability of pulling a second orange block is 2/11. Therefore, the overall probability is (3/12) * (2/11) = 3/55. Choice A (1/12) is incorrect because it only considers the probability of the first orange block being pulled. Choice C (1/55) is incorrect as it represents the probability of pulling two orange blocks in a row, not the consecutive pulls after the initial pull. Choice D (2/33) is incorrect as it does not reflect the correct calculation for the consecutive pulls of orange blocks.
2. Vacuoles are large sacs for storage in plant cells. What is their main function in animal cells?
- A. Protein synthesis
- B. Waste storage and disposal
- C. Photosynthesis
- D. Cellular respiration
Correct answer: B
Rationale: Vacuoles in animal cells primarily function in waste storage and disposal, helping to maintain cellular homeostasis by storing waste products and aiding in their removal from the cell. Unlike plant cells, animal cells do not typically use vacuoles for storage purposes such as water, nutrients, or pigments. Instead, animal cells rely on other organelles like lysosomes for waste management and maintaining cellular balance. Choices A, C, and D are incorrect because protein synthesis occurs in ribosomes, photosynthesis takes place in chloroplasts (absent in animal cells), and cellular respiration mainly occurs in mitochondria, respectively. Vacuoles in animal cells serve a different purpose compared to plant cells.
3. Which of the following sentences contains a correct example of subject-verb agreement?
- A. All of the board members are in agreement on the issue.
- B. Each of the students was concerned about the test scores for the final exam.
- C. Neither of the children is at home right now.
- D. Any of the brownie recipes is perfect for the bake sale.
Correct answer: A
Rationale: The correct answer is A. In this sentence, the subject 'all of the board members' is plural, and the verb 'are' agrees with it. In choice B, 'each of the students' is singular, so the verb should be 'was' instead of 'were.' Choice C should use 'is' instead of 'are' since 'neither of the children' is singular. In choice D, 'any of the brownie recipes' is singular, so 'is' should be used instead of 'are.' Therefore, only choice A demonstrates proper subject-verb agreement.
4. What is 0.875 as a simplified fraction?
- A. 7/8
- B. 9/10
- C. 5/6
- D. 3/4
Correct answer: A
Rationale: To convert 0.875 to a fraction, we write it as 875/1000. Then, simplify the fraction by dividing both the numerator and denominator by 125 to get 7/8, which is the simplest form of the fraction. Choice B (9/10), Choice C (5/6), and Choice D (3/4) are all incorrect because they do not represent the value of 0.875 when expressed as a fraction.
5. Which of the following is NOT a symptom of asthma, a chronic respiratory condition?
- A. Wheezing
- B. Difficulty breathing
- C. Chest tightness
- D. Fever
Correct answer: D
Rationale: The correct answer is 'Fever.' Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing, difficulty breathing, and chest tightness due to inflammation and narrowing of the airways. Fever is more commonly seen in conditions such as infections or inflammatory diseases rather than asthma. Choices A, B, and C are common symptoms of asthma and are related to the constriction and inflammation of the airways, leading to breathing difficulties and chest discomfort.
