15 sqrt a ^4
Step-by-step explanation:
Answer: 1, 3, 6
Step-by-step explanation:
With the concept of first in, first out method, then we
can use the formula below to solve for the number of equivalent units of
production for that period.
number of equivalent units of production
= Total number of units completed during that period (A) –
Number of units completed in process at the beginning of the period (B) +
Number of units completed at the end of the period (C)
= A – B + C
We know that,
A = 9000 units
So we solve for B and C.
B is 60% of the 500 units, therefore:
B = 0.60 * 500 = 300
C is 30% of the 600 units, therefore:
C = 0.30 * 600 = 180
Substituting the values into the equation:
number of equivalent units of production = 9000 – 300 + 180
number of equivalent units of production = 8880 units
Answer:
A. 8880
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The number of keys is n
The number of keys remaining after the first key is chosen is n-1
The probability that he gains entrance with the first key he selects is 
Generally the probability that the first key does not open the door is

Generally the number of keys remaining after the second key is chosen is
n-2
Generally the probability that he gains entrance with the second key he selects is

Generally the probability that the second key does not opens the door is

Generally the probability that he gains entrance with the third key he selects is

Generally the probability that the door opens with the third key

=> 
=>
