Exploring STAAR Algebra 1 EOC Released Exam Questions 11-15

The video tutorial covers problems 11 to 15 from a released Algebra 1 exam. It begins with solving problem 11 using a calculator to find the correct answer from a table of values. Problem 12 involves calculating the volume of a rectangular prism using a formula. Problem 13 focuses on graphing and understanding the slope of a line. Problem 14 requires calculating the pay difference between senior and junior employees. Finally, problem 15 discusses the concepts of independent and dependent variables in the context of burning calories over time.

What is the first step in solving problem 11 using a calculator?

• Input the entire equation and solve for x

• Convert the equation to a simpler form

• Cross out incorrect options based on the table

• Use the 'second graph' function to find a table of values

What does plugging in 5 into the equation in problem 11 yield?

• A value of 0

• A value of 5

• A value of 78.5

• An undefined result

What does the 'Big B' represent in the volume formula for a prism?

• The height of the prism

• The width of the prism

• The volume of the prism

• The area of the base of the prism

What is the formula for the volume of a prism?

• Length + Width + Height

• Length x Width x Height

• Base Area x Height

• 2(Base Area + Height)

How is the slope of a line determined from its graph?

• By comparing the x-intercept to the y-intercept

• By measuring the vertical distance only

• By the length of the line

• By the rise over run method

Which slope is steeper than -1/2?

• -1/3

• 2/3

• -2/3

• 1/2

What is the hourly wage of the junior employee?

• $10.25

• $39.50

• $14.00

• $18.45

How many hours did the senior employee work?

• 20 hours

• 16 hours

• 18 hours

• 14 hours

In the context of burning calories, what is the independent variable?

• The type of exercise performed

• The number of calories burned

• The duration of the exercise in minutes

• The intensity of the exercise

What determines the dependent variable in an experiment?

• The control variable

• The constant variable

• The variable that is measured

• The variable that is manipulated
