A study found that 9% of dog owners brush their dog’s teeth. Of 578 dog owners, about how many would be expected to brush their dog’s teeth? Explain.
1 point
50; 9% ≈ 10% and 578 should be rounded down to 500; 10% of 500 = 50
60; 9% ≈ 10% and 578 ≈ 600; 10% of 600 = 60
70; 9% ≈ 10% and 578 ≈ 700; 10% of 700 = 70
100; 9% ≈ 10% and 578 should be rounded up to 1,000; 10% of 1,000 = 100

Solve the inequality, then identify the graph of the solution. 2x – 1 > x + 2

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

What number line represents the solution set for the inequality -1/2 greater than or equal to 4
