Answer: option d.
Step-by-step explanation:
You have the following formul given in the problem:
You know that:
The number of customers serviced in an hour by the technical support representative is 6 costumbers, therefore:
As the problem asked for the probability that a costumber will be on hold less than 30 minutes, we know that:
Substitute the values above into the formula.
Then, you obtain:
or 95%
Divide each cost over the number of bottles
For the 6-pack, we have
3.79 dollars divided by 6 = 3.79/6 = 0.6317 which rounds to 0.63
So we pay $0.63 per bottle or 63 cents per bottle
-------------------------------------
For the 9-pack, we have
4.50 dollars divided by 9 = 4.50/9 = 0.50
meaning we pay $0.50 per bottle or 50 cents per bottle
-------------------------------------
For the 12-pack, we have
6.89 dollars divided by 12 = 6.89/12 = 0.57416 which rounds to 0.57
So we pay $0.57 per bottle or 57 cents per bottle
-------------------------------------
In summary we have
The 6-pack costing 63 cents per bottle
The 9-pack costing 50 cents per bottle
The 12-pack costing 57 cents per bottle
The lowest per bottle cost is 50 cents per bottle, which is for the 9-pack
The 9-pack is the best deal of the three deals.
Answer:
I'm getting
y=-7x+8
The 7 is negative for me..You should maybe try yourself too and see what you get I might have made a mistake
Step-by-step explanation:
I'm guessing you live somewhere in the U.S. so I'll use the equation you use there
Equation:
first pick two points
I'll pick (0,8) and (1,1)
this means that the slope is -7
So far the equation will look like this
to get b pick one point, I'll pick (0,8) and replace y and x
when you solve this you'll get b
So the equation will look this
Answer with explanation:
--------------------------------------------------------Dividing both sides by 8 x
This Integration is of the form ⇒y'+p y=q,which is Linear differential equation.
Integrating Factor
Multiplying both sides by Integrating Factor
When , x=1, gives , y=9.
Evaluate the value of C and substitute in the equation 1.
Answer:
$5277.88
Step-by-step explanation:
We want to find what the measure of the outside of the garden is
We can use circumference, because it is the distance around the edge of a circle
The circumference formula is:
c= 2r
Substitute 70 in for r(radius)
c= 2*70
c= 140
c=439.822971503 meters
Now to find the cost
Multiply the cost of fencing per meter by the circumference
439.822971503*12=5277.87565803
The fencing will cost about $5277.88
