Line ef has an equation of a line y= -1/2x +7. what is the slope of a line that is perpendicular to that

What number should be added to both sides of the equation to complete this square? x^2-10x=7

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
