<h3>Solution:</h3>
- Here, the whole line segment is AD.
- So, AB + BC + CD = AD.
- Given, AD = 20
- BC = 2
- AB = 12x
- CD = x + 12
- Therefore,
AB + BC + CD = AD
or, 12x + 2 + x + 12 = 20
or, 13x + 14 = 20
or, 13x = 20-14
or, 13x = 6
or, x = 6/13
<h3>Answer:</h3>
x = 6/13

Answer: The correct choice is D.
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
Answer:
to guarantee that both formulas are the same.
Step-by-step explanation:
Dimensionally speaking, the volume is the cube of length. By direct comparison, we find that 
have length units, whereas 
have area unit, that is, the square of length.
Hence, to guarantee that both formulas are the same.
Coefficients are the numbers by themselves so B.
Hope that helped my friend!! :D
