What is the possible weight between 0 pounds and 10 pounds is in the shape of rectangle

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

Solve the following inequalities and show the solution on a number line. 3/4 (2x-7) ≤ 5

Select the margin of error that corresponds to the sample mean that corresponds to each population: a population mean of 360, a standard deviation of 4, and a margin of error of 2.5%
