A merchant has announced 25% rebate on prices of ready made garments at the time of sale. If a purchaser needs to have a rebate of X 400, then how many shirts, each costing X 320, should he purchase?

Four waves are to be sent along the same string, in the same direction : y_(1) (x,t)=(5.00 mm) sin (4pi x-400pit) y_(2) (x,t) =(5.00 mm) sin (4pi x-400 pit+0.8pi) y_(3) (x,t) =(5.00 mm) sin (4pi x-400pit+pi) y_(4) (x,t)=(5.00 mm) sin (4pi x-400 pit+1.8pi) What is the amplitude of the resultant wave?

The electric field in a region of space has the components E_(y) = E_(z) =0 and E_(x)= (4.00 N//C)x^(2) . Point A is on the y axis at y = 3.00 m, and point B is on the x axis at x = 4.00 m. What is the potential difference V_(B) - V_(A) ?

X ~ B(400, 1//5) then find its standard deviation
