Answer:45
Step-by-step explanation:
9 and 15 both go into 45, and 45 is the LCM of those numbers.
Answer:
a) 19/20
b) 1/20
Step-by-step explanation:
a) calculate the fraction of the attendants time will be spent servicing cars
l / L > 0 = Ц / [ Ц - λ ] = 20 --- ( 1 )
Ц (service ) = 15 hour
∴ λ ( arrival rate ) = 14.25
P = λ / Ц = 14.25 / 15 = 0.95 = 19/20
<u>b) Fraction of potential customers lost </u>
Ls = P / ( 1 - P )
where ; P = 19/20
Ls ( fraction of potential customers lost ) = 19/20 / ( 1 - 19/20 ) = 19
hence proportion of customers lost = 1 - 19/20 = 0.05 = 1/20

Answer:
Last option
−1 • f(x)
Step-by-step explanation:
The function 
passes through point (-1, 2) because:
and also goes through the point (0, 1)
Because:
Then, if the transformed function passes through the point (0, -1) and passes through the point (-1, -2) then this means that the graph of reflected on the axis x. This means that if the point 
belongs to f(x), then the point 
belongs to the transformed function
The transformation that reflects the graph of a function on the x-axis is.
Where c is a negative number. In this case 
Then the transformation is:
and the transformed function is:
