What is the term that is described by the assumption that which treatment a subject gets makes absolutely no difference in an experiment?
What is null hypothesis.
Write the following conjecture in equation form (use x for the smaller number): "The sum of two consecutive odd numbers is equal to 35."
What is "If a and b are two consecutive odd numbers, then (x + (x+2))=35."

What is, "No Solution"?
When a shape undergoes a size transformation of size 5, what happens to the angles and sides of the new image?
What is the angles stay the same and the sides are 5 times larger.
What are the three types of statistical studies?
What is sample survey or poll, experiment, and observational study.

What is 32%.
Write an equation for the following number trick in simplest form: "Pick a number. Triple it. Subtract 3 to the result. Multiply that result by 4. Subtract 8 from that result."
What is, "12x - 20"?

What is, (show a graph with one line with x intercepts at -6 and y intercept on -4 shaded below the line, and the second line with x intercept at 1 and y intercept at 2 shaded above)
What does CPCTC stand for?
What is Corresponding Parts of Congruent Triangles are Congruent.
