Answer:
Outdoors
Explanation:
Construction workers perform outdoors.
Answer:
F(x) = 0 ; x < 0
0.064 ; 0 ≤ x < 1
0.352 ; 1 ≤ x < 2
0.784 ; 2 ≤ x < 3
1 ; x ≥ 3
Explanation:
Each wafer is classified as pass or fail.
The wafers are independent.
Then, we can modelate X : ''Number of wafers that pass the test'' as a Binomial random variable.
X ~ Bi(n,p)
Where n = 3 and p = 0.6 is the success probability
The probatility function is given by :

Where
is the combinatorial number

Let's calculate f(x) :




For the cumulative distribution function that we are looking for :



The cumulative distribution function for X is :
F(x) = 0 ; x < 0
0.064 ; 0 ≤ x < 1
0.352 ; 1 ≤ x < 2
0.784 ; 2 ≤ x < 3
1 ; x ≥ 3
The all purpose one will work or you could use type C I believe.
Answer:
b. diagnoses and corrects errors in an operational system
Explanation:
Corrective maintenance is one that is performed with the purpose of repairing faults or defects that occur in equipment and machinery. As such, it is the most basic way of providing maintenance, as it simply involves repairing what has broken down. In this sense, corrective maintenance is a process that basically consists of locating and correcting faults or damages that are preventing the machine from performing its function in a normal way.
