Answer:

Step-by-step explanation:
first you take 60°/360°= 1/6 then you take 1/6 and multiple it by
and that equals
finally take
times the radius (6) and that should equal 
PLATO USERS #platolivesmatters
Answer:
Option d
Step-by-step explanation:
We need 2 fundamental data to solve this problem.
1.- Average number of clients attended in 1 hour.
2.- Time in which it is expected that a client will be attended.
They tell us that the average number of clients served in an hour is m = 8
They tell us to calculate the probability that the client will be seen in less than 15 minutes.
But the time t in the formula is given in hours.
Therefore we must write 15 minutes according to hours.
We know that
.
So:
.
Now we substitute in the formula
and
to find P.

Answer:
is equivalent to
and 
is equivalent to
and
.
The expressions which are equivalent to neither:
and 
Step-by-step explanation:
Given the expressions:
1) 
2) 
To find:
The expressions equivalent to the given expressions.
or the expressions which are not equivalent to any of the given expressions.
Solution:
First of all, let us solve the brackets from the given expressions.
can be written as
(because when we multiply a negative sign with negative, it becomes positive.)
Similarly
can be written as
(because when we multiply a positive sign with negative, it becomes negative.)
Therefore, the answer is:
is equivalent to
and 
is equivalent to
and
.
The expressions which are equivalent to neither:
and
