Answer:
-4/3 (Answer A)
Step-by-step explanation:
Here we go from the point (-3, 3) on the left to the point (0, -1) on the right. It is immediately apparent that x (the run) increases by 3 from -3 to 0 and that y (the rise) decreases by 4 from 3 to -1. Thus, the slope of this line (which is also the rate of change) is
m = rise / run = -4/3 (Answer A)

Step-by-step explanation:
The volume cannot be 15 cm³ because it is not a perfect cube.
V = x³
let x = 4 then x³ = 4³ = 64 ← a perfect cube
There is not an integer when cubed gives 15
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
