6 / (x+1) = 1/2
x +1 = 12
x = 11
Answer is d ....(11)
Answer:
1/13
Step-by-step explanation:
There exactly 7 seniors 10 Juniors, 12 sophomores and 11 freshman
in which 4 of the juniors are Female , and exactly 2 of the sophomores are male. Therefore,
10-4= 6 juniors are male
12-2 = 10 female sophomores
Total = 7+10+12+11= 40 students
P(male junior then female soph.)= 
P(female soph then male junior)= 
Therefore the final answer will be = 1/26 +1/26= 1/13
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The capacity of the metal tank is 
The duration usage is 
The cost of 2000-gallon tank 15 years ago is 
The capacity of the second tank considered is
The power sizing exponent is 
The initial construction cost index is 
The new construction after 15 years cost index is 
Equation for the power sizing exponent is mathematically represented as
![\frac{P_n}{P} = [\frac{C_1}{C} ]^{e}](https://tex.z-dn.net/?f=%5Cfrac%7BP_n%7D%7BP%7D%20%3D%20%5B%5Cfrac%7BC_1%7D%7BC%7D%20%5D%5E%7Be%7D)
=> Here
is the cost of 5,000-gallon tank as at 15 years ago
So
![P_n = [\frac{5000}{2000} ] ^{0.57} * 100000](https://tex.z-dn.net/?f=P_n%20%20%3D%20%20%5B%5Cfrac%7B5000%7D%7B2000%7D%20%5D%20%5E%7B0.57%7D%20%2A%20100000)

Equation for the cost index exponent is mathematically represented as

Here
is the cost of 5,000-gallon tank today
So
