Answer:
The number of commercials is 340 and the number of movies are 334.
Step-by-step explanation:
Let the number of commercials be = C
number of movies be = M
According to given conditions:
C = 6 + M --------- eq1
C + M + 6 = $680 ------ eq2
Putting eq1 in eq2:
6 + M + 6 + M = $680
12 + 2M = $680
Subtracting 12 from both sides:
2M = $680 - 12
2M = 668
Dividing both sides by 2:
M = 668/2
M = 334
For finding number of movies put value of M in eq 1
C = 334 + 6
C = 340
So The number of commercials is 340 and the number of movies are 334.

95+(3x+23)+(7x-4)+(9x-6)+90 = (5-2) x 180
x = 18

41+(3x+6)+(7x-11)+62+(4x+7)+(6x-5) = 360
x = 13
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
