Answer:
(a) P(A1 ∪ A2) = 0.35
Step-by-step explanation:
(a) A1 ∪ A2 :
We start by defining the events.
A1 : '' awarded project 1''
A2 : ''awarded project 2''
A3: ''awarded project 3''
In set theory we write the union of events A and B as A∪B.
A∪B means that the event A occurs,event B occurs or either both events occurs at the same time.
The probability is given by the equation :
P(A∪B) = P(A) + P(B) - P(A∩B) (1)
Where the event (A∩B) is the event where A and B occur at the same time
and P(A∩B) is the probability of (A∩B)
Using the equation (1) :
P(A1 ∪ A2) = P(A1) + P(A2) - P(A1∩A2)
P(A1 ∪ A2) = 0.22 + 0.25 - 0.12
P(A1 ∪ A2) = 0.35

Answer:
d(t) = -100t
Step-by-step explanation:
The general expression for the linear model is:
Since the submarine already starts at sea level, b=0:
The constant "m" is the rate at which the submarine descends in feet per minute. Considering depth as a negative quantity, m=-100
The linear model that represents the depth of the submarine relative to sea level, in feet, after t minutes is d(t) = -100t.
