TEAS Practice Test Math

Correct Answer: C

Rationale: To find out how much ammonia is needed, we first calculate the total amount of ammonia needed for 230 gallons of solution. Since 1 gallon requires 6 oz of ammonia, for 230 gallons, we multiply: 230 (gallons) x 6 (oz) = 1380 oz of ammonia. Therefore, the correct answer is C: 1380 oz. Other choices are incorrect because: A: 1380 gallons - This does not make sense as we are calculating the amount of ammonia, not the total volume of cleaning solution. B: 6900 gallons - This is not a logical calculation based on the given information. D: 1400 oz - This is close to the correct answer but miscalculates the total amount of ammonia required.

Correct Answer: C

Rationale: The correct answer is C: Dependent. In this study, the weight of the babies is the variable being measured and studied in relation to different time intervals after birth. The weight of the babies depends on the time intervals, making it the dependent variable. Other choices are incorrect because: A: Independent variable is the variable that is manipulated or controlled by the researcher, in this case, time intervals are the independent variable. B: Control variable is a variable that is kept constant to prevent it from influencing the results, weight is not a control variable. D: Constant is not applicable in this context as weight is not a constant value in the study, it varies with time intervals.

Correct Answer: D

Rationale: To determine the correct order of the groups, we need to compare the fractions given for each group. Group X has 1/4 of the doctors, Group Y has 1/3, and Group Z has 1/6. Comparing the fractions, we see that 1/3 is larger than 1/4 but smaller than 1/6. Therefore, Group Y has the most doctors, followed by Group X, and then Group Z. Hence, the correct order is D: Group Y, Group X, Group Z. This is because Group Y has the largest fraction of doctors, followed by Group X, and then Group Z. Choices A, B, and C can be eliminated because they do not follow the correct order based on the fractions provided.
