A graph’s vertical axis is labeled “revenue, in thousands of dollars.” A point has vertical coordinate 2.7. What revenue, in dollars, does it represent?
Enter an integer, decimal or fraction without units. Use up to 5 characters, or 6 including a leading minus.
2,700 dollars. A value of 2.7 on an axis measured in thousands of dollars means 2.7(1,000)
Review Test orientation and diagnostic
Write your complete response before opening the model answer. Compare both your answer and your reasoning.
A question’s exact answer is −. Give two valid numeric-entry forms.
For example, -11/4 or -2.75. The improper fraction −11/4 equals −2.75. Both fit the negative-response character limit and retain the minus sign. Do not enter a mixed number, an equals sign, or explanatory text in a numeric field. Repair: Example 1.03.
What is the value of ? Write a matching linear calculator entry.
2; enter (24-8)/(2+6). The fraction bar groups both sums or differences. Compute the numerator 24 − 8
A student gets 16 of 20 practice questions correct but cannot explain 3 of those correct answers. How many answers are secure, and how many questions belong in the review pool?
13 secure answers; 7 review items. Of the 16 correct answers, 3 are not explainable, so 16 − 3
Treat any error in target, entry, or units as worth repairing immediately: those habits recur in every domain. A secure answer includes a reason, not just a matching number. Use a fresh item after reviewing; repeating a memorized answer is not a reliable retest.
You should be able to identify the requested quantity, preserve grouping in calculator entry, read scaled units, enter a numeric answer correctly, and separate a guess from an explainable solution. A test-taking routine supports mathematics; it does not replace it.
