The management of white industries is considering a new method of assembling its golf cart. the present method requires a mean time of 42.3 minutes to assemble a cart. the mean assembly time for a random sample of 24 carts, using the new method, was 40.6 minutes, and the standard deviation of the sample was 2.7 minutes. using the 0.10 level of significance, can we conclude that the assembly time using the new method is faster

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

the correct answer is c
