Abox contains 13 red hats, 15 white hats, 18 blue hats, and 14 brown hats. nina randomly chooses a hat from the box.

what is the probability that it will not be white? write your answer as a decimal.

13 + 15 + 18 +14 = 60 total hats

15 are white

60-15 = 45 hats that are not white

45/60 reduces to 3/4

 3/4 =0.75 probability the hat will not be white

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)
