Assume that women's heights are normally distributed with a mean given by h = 62.3 in, and a standard deviation given by 0 = 3.1 in. (a) If 1 woman is randomly selected, find the probability that her height is less than 63 in.
(b) If 49 women are randomly selected, find the probability that they have a mean height less than 63 in.
(a) The probability is approximately
(Round to four decimal places as needed.)

i used to know but i learned it a long time ago sorry

step-by-step explanation:

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

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)
