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.
Answer:
AT=6, RC=5
Step-by-step explanation:
Perpendicular bisector intersect at T that is the circumcenter.
since RT is a bisector or AC and AR=5 then RC=5
Circumcenter is equidistant from the vercices of the triangle so
AT≅BT≅CT
but CT is given to be CT=6 so AT=6
Answer:
The answer is B lol
Step-by-step explanation:
I know this is late and you probably got the answer but just in case its C. 5. :P
When dividing by zero you can’t divide anything With it and it can’t equals zero because that would be wrong it would have to be undefined
