TEAS Math Questions

1. What is the range in the number of flights made per month by the flight attendant?

Correct answer: C

Rationale: The range is calculated by finding the difference between the highest and lowest values. In this case, the highest number of flights made per month is 32, and the lowest is 3. Therefore, the range is 32 - 3 = 29. Choice C, '29', is the correct answer. Choice A, '20', Choice B, '25', and Choice D, '32', are incorrect as they are individual data points and do not represent the range, which is a measure of spread between the highest and lowest values.

2. Which of the following hormones is produced by the adrenal medulla and prepares the body for a stressful situation?

Correct answer: C

Rationale: The correct answer is C: Epinephrine (adrenaline). Epinephrine is produced by the adrenal medulla and is responsible for preparing the body for a stressful situation. It increases heart rate, dilates airways, and mobilizes energy stores to help the body respond to a fight-or-flight scenario. Testosterone (Choice A) is a sex hormone produced by the testes in males and in smaller amounts by the ovaries in females, not by the adrenal medulla. Cortisol (Choice B) is a stress hormone produced by the adrenal cortex, not the adrenal medulla. Growth hormone (Choice D) is produced by the pituitary gland and is involved in growth, metabolism, and various bodily functions, not by the adrenal medulla.

3. Which measure for the center of a small sample set would be most affected by outliers?

Correct answer: A

Rationale: The mean is calculated by summing all values in a dataset and then dividing by the total number of values. Outliers, which are data points significantly different from the other values, can greatly impact the mean because they affect the sum. The mean is sensitive to extreme values, making it the measure for the center of a small sample set most affected by outliers. The median, on the other hand, is not influenced by outliers as it represents the middle value when the data points are ordered. The mode is the value that appears most frequently in the dataset and is not directly influenced by outliers. Therefore, the correct answer is the mean, as it is highly influenced by outliers in a small sample set.

4. The first midwife uses 2/5 of her monthly contribution to pay for rent and utilities. She saves half of the remainder for incidental expenditures, and uses the rest of the money to purchase medical supplies. How much money does she spend on medical supplies each month?

Correct answer: A

Rationale: The first midwife contributes $2000. She spends $800 on rent and utilities. After paying for rent and utilities, $1200 remains. Half of this amount, which is $600, is saved for incidental expenditures. Therefore, the first midwife spends the remaining $600 on purchasing medical supplies each month. Choice A, $600, is the correct answer. Choices B, C, and D are incorrect as they do not accurately reflect the amount spent on medical supplies as calculated in the given scenario.

5. Which organ system is primarily responsible for transporting nutrients throughout the body?

Correct answer: C

Rationale: The circulatory system, also known as the cardiovascular system, is primarily responsible for transporting nutrients and oxygen throughout the body. The heart pumps blood through blood vessels, delivering essential nutrients to cells and tissues. This system consists of the heart, blood vessels, and blood, working together to ensure the proper distribution of nutrients and removal of waste products. Choice A, the respiratory system, is responsible for gas exchange (oxygen and carbon dioxide) and not primarily involved in nutrient transportation. Choice B, the digestive system, is responsible for breaking down food and absorbing nutrients but does not transport nutrients throughout the body. Choice D, the nervous system, controls and coordinates body functions through electrical signals and is not directly involved in nutrient transportation.
