Answer:
Expected number of guests is 100.4.
Step-by-step explanation:
It is given that there are 161 guest if there is a heavy snow fall.
Also, the probability for a heavy snow fall is 0.40.
Therefore, P(X = 161) =0.4.
It is also given that there are 60 guests if there is a light snow fall.
The probability for a light snow fall is 1 - 0.4 = 0.6.
Therefore, P(X = 60) = 0.6.
Expected number of guests = (161)P(X = 161) + (60)P(X = 60)
= 161(0.4) + 60(0.6)
= 64.4 + 36
= 100.4
No of those are correct it would be 1.416 repeating
Answer:
y = 1/4x + 7
Step-by-step explanation:
A perpendicular line will have an opposite reciprocal slope, so the slope will be 1/4
Plug in the given point and slope into y = mx + b, then solve for b
y = mx + b
5 = 1/4(-8) + b
5 = -2 + b
7 = b
Plug in b and the slope into y = mx + b
y = 1/4x + 7
So, the equation of the line is y = 1/4x + 7
