Answer:
39.30 
Step-by-step explanation:
The area of the top surface of the wedge is the same as the area of a sector.
Area of a sector = (θ/
)

where: θ is the central angle, and r is the radius.
Given that: central angle =
, radius = 10 centimetre.
Area of the top surface = Area of a sector = (θ/
)

= 39.30 
The area of the top surface of the wedge is 39.30

Answer:
a. 0.4
b. Not independent.
Step-by-step explanation:
a. We use the probability table attached below for our calculations.
-the probability that an agreement is reached on both sides is obtained from the table:

b. To determine whether the two events are independent, we compare the probabilities
and
where i denotes insurance and s denotes salaries:

Two events are considered to be independent, if and only if:

Hence, the events are not independent.
