Ohio State Test Algebra I Practice
Algebra I practice covers the 43 standards on Ohio’s Algebra I blueprint in three reporting categories: Number, Quantities, Equations and Expressions; Functions; and Statistics. The end-of-course test has two parts, with a calculator on the whole test. It also counts toward graduation.

Pick an answer to see the worked solution.
A pump moves water out of a flooded basement at a rate of 12 gallons per minute. The pump runs for 2.5 hours. How many gallons of water does it move?
Choose an answer to see the worked solution.
Worked solutionThe rate is in gallons per minute, so the time must be in minutes: 2.5 hours × 60 minutes per hour = 150 minutes. Then 12 gallons per minute × 150 minutes = 1,800 gallons; the minutes cancel and gallons are left. 30 gallons multiplies 12 by 2.5 without changing hours to minutes. 720 gallons is the amount for only 1 hour. 4.8 gallons divides 12 by 2.5, which does not give gallons at all.
The lines 2x + y = 7 and x − y = 2 cross at (3, 1). Adding the two equations gives 3x = 9, whose graph is the vertical line x = 3.
Which statement is true?
Choose an answer to see the worked solution.
Worked solutionEvery point that is on both original lines makes both equations true, so it makes their sum true too: (3, 1) gives 3(3) = 9. The new line x = 3 is a different line, but it passes through the same crossing point, and it crosses 2x + y = 7 only there (y = 7 − 6 = 1).
(9, 0) forgets to divide 9 by 3. A new line does not mean a new solution: it is drawn through the old crossing point. An equation with no y is a vertical line, which still crosses 2x + y = 7 exactly once.

Data set A is 10, 12, 14, 16, 18. Data set B is the same five values plus one more value, 50.
Using the median of each half for the quartiles, how do the standard deviation and the interquartile range of B compare with those of A?
Choose an answer to see the worked solution.
Worked solutionFor A, Q1 is the median of 10, 12, which is 11, and Q3 is the median of 16, 18, which is 17, so the IQR is 6. For B the halves are 10, 12, 14 and 16, 18, 50, so Q1 = 12 and Q3 = 18: the IQR is still 6, because the quartiles only look at middle positions, not at how far the largest value is. The standard deviation measures distance from the mean, and 50 is 30 above B's mean of 20, so it jumps from about 3 to about 14 (technology gives 3.16 and 14.97 for the sample standard deviations).
One value is enough to move the standard deviation a lot, so “both stay the same” is wrong. The IQR, not the standard deviation, is the one that resists the outlier. 32 is how far 50 is from 18; neither statistic changes by that amount.

Teacher questions
When should I use each part?
Assign each practice set as you teach its topics, then give the full-length practice test once everything has been taught.
What about calculators?
The practice follows the state's calculator rule for this course: a calculator on the whole test. Check your school's testing guidance for the current rules.
Are these actual state test questions?
No. Every item is original and aligned to the published standards. Nothing is copied from a state test, a released item or a reference sheet.
