Practice Math TEAS TEST

Correct Answer: A

Rationale: The correct way to display the frequency for each day of the week when students get up after 8 a.m. is through a histogram. Histograms are used to display the distribution of continuous data into intervals or bins, making them ideal for showing frequency distributions. In this case, each day of the week can be represented along the x-axis, with the frequency of students getting up after 8 a.m. on the y-axis. By using a histogram, we can easily visualize and compare the frequency of waking up late on different days. Summary: - Choice A (Histogram) is correct as it effectively displays frequency distributions. - Choice B (Pie chart) is not suitable for showing frequency distributions of days of the week. - Choice C (Bar graph) could work but histograms are more specifically designed for this purpose. - Choice D (Scatter plot) is used to show relationships between two continuous variables, not frequency distributions.

Correct Answer: A

Rationale: The correct answer is A: One. Any number raised to the power of zero equals one. This is because the rule for exponents states that any number raised to the power of zero is equal to one, regardless of the base number. This rule is derived from the properties of exponents and is a fundamental concept in mathematics. Choices B, C, and D are incorrect because raising a number to the power of zero does not result in the number itself, zero, or two. The key to remember is that any number raised to the power of zero is always equal to one, making choice A the correct answer.

Correct Answer: A

Rationale: The correct answer is A: Itself. Any number raised to the power of 1 remains the same number. This is because any number to the power of 1 is equivalent to multiplying that number by 1, which does not change the value of the number. Therefore, when a number is raised to the power of 1, the result is the number itself. Summary of incorrect choices: B: One - Raising any number to the power of 1 does not always result in 1, it results in the original number itself. C: Zero - Raising any non-zero number to the power of 1 does not result in 0. D: The number multiplied by 2 - Raising a number to the power of 1 does not double the number, it remains the same.

Correct Answer: A

Rationale: The correct answer is A: 1000 mL. This is because there are 1000 milliliters in a liter based on the metric system conversion. 1 liter is equal to 1000 milliliters. Therefore, to convert liters to milliliters, you simply multiply the number of liters by 1000. Choice B: 100 mL is incorrect because it is not the standard conversion factor for liters to milliliters. Choice C: 10 mL is incorrect as it is too small of a quantity to be equivalent to a liter. Choice D: 1 mL is incorrect as it is significantly less than a liter.

Correct Answer: A

Rationale: The correct answer is A: 9.0 inches. To calculate the total rainfall for May, June, and July, we add up the rainfall values for these months on the graph. May has 3 inches, June has 2.5 inches, and July has 3.5 inches. Adding these values together gives us 3 + 2.5 + 3.5 = 9.0 inches. Therefore, the correct total rainfall for these months is 9.0 inches. Choice B (8.4 inches) is incorrect because it does not match the sum of the rainfall values for May, June, and July. Choice C (7.5 inches) is also incorrect as it is lower than the actual total. Choice D (10.5 inches) is incorrect as it is higher than the actual total calculated from the graph.
