4) Experience shows that a ski lodge will be full (162 guests) if there is a heavy snow fall in December, while only partially full (53 guests) with a light snow fall.
What is the expected number of guests if the probability for a heavy snow fall
is.40? Assume that heavy snowfall and light snowfall are the only two
possibilities.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the answer would be 0.54
