Answer:
Step-by-step explanation:
It has been established that the count of drivers traveling between a specific origin and destination in a certain time frame follows a Poisson distribution with a mean μ = 20 (as indicated in the article "Dynamic Ride Sharing: Theory and Practice"†).
a) 
b) 
c) 
d) 2 standard deviations = 2(20) = 40
Thus, this means the range for 2 standard deviations is
20-40, 20+40
which equates to (0,60)
Respuesta:
126 pies
Explicación paso a paso:
Dado que:
Ecuación de la línea que representa el sendero de naturaleza:
y = 13x - 4
Distancia del gazebo respecto al sendero de naturaleza:
Cada unidad en el plano de coordenadas = 10 pies
Por lo tanto,
y = 13(10) - 4
y = 130 - 4
y = 126 pies
Begin by determining the increase in price for the iPads: $50 multiplied by 10 equals $500. Thus, the iPad's price was raised by $500. Next, subtract this total from the original iPad price: $5,000 minus $500 results in $4,500. This indicates that the actual cost for 10 iPads, unadjusted by the increase, stands at $4,500. To find the individual iPad cost, divide that total by 10, leading to $4,500 divided by 10, which gives $450. Therefore, the manufacturing cost of each iPad is $450.
This may be a bit awkward to explain in writing, so please bear with me:)
You are given the equations. Begin by focusing on ad = 11.6. Treating variables normally, this reads as a times d = 11.6.
From that, d = 11.6/a by dividing both sides by a.
With d expressed, substitute (11.6/a) into cd = 6.7. Then isolate c by multiplying both sides by a/11.6, yielding c = (6.7a)/11.6.
Now that c is known, insert (6.7a)/11.6 for c in bc = 8.3. The algebra becomes a bit messy, but solving for b gives approximately 14.3705 / a. Since you need ab, multiply both sides by a, and rounding to one decimal place produces ab = 14.4
