What translation maps the function f(x) = x2 + 3 onto the function g(x) = (x+2)2 ‒ 4? A. move f(x) to the right 2 units and up 7 units B. move f(x) to the left 2 units and down 7 units C. move f(x) to the right 7 units and up 2 units D. move f(x) to the left 7 units and down 2 units

Facial shaving brushes are either bulb-shaped or fan-shaped. an experiment is to be conducted to determine whether the lather thickness is the same for both types of shaving brushes. in previous studies, it was determined that shaving brush size (small, medium, large) is associated with lather thickness, but shaving brush type (wolf whiskers, maggard razors, frank shaving, and so on) is not associated with lather thickness. how could the experiment best be conducted? by blocking on shaving brush size by blocking on shaving brush type by blocking on shaving brush shape by blocking on lather thickness without blocking

Arandom variable x has a mean of 10 and a standard deviation of 3. if each value of x is multiplied by 2, what will the new mean and standard deviation be?

Aparticular electrical signal being transmitted to a neuron is sufficient to generate an action potential. if the magnitude of the incoming electrical signal is doubled, the action potential will
