Acircle has diameter endpoints at (7,2) and (p,8), p > 0, and the circle is tangent to the x axis. the circle’s equation can be written (x-h)^2+(y-k)^2=n.

what is the value of h+k+n?

Asystem of equation is shown below 6x - 2y equals 3 . and 5x + 3y equals 4. would you solve by substitution or elimination? and why

An assembly consists of two mechanical components. suppose that the probabilities that the first and second components meet specifications are 0.87 and 0.84. assume that the components are independent. determine the probability mass function of the number of components in the assembly that meet specifications. x
