100% = 70
1% = .7 (divide by 100)
12% = 8.4 (Multiply 1% by 12)
70 - 8.4 = 61.6 (New Price)

lakkis [162]

The Poisson distribution defines the probability of k discrete and independent events occurring in a given time interval.
If λ = the average number of event occurring within the given interval, then
$P(k \, events) = e^{-\lambda } ( \frac{\lambda ^{k}}{k!} )$

For the given problem,
λ = 6.5, average number of tickets per day.
k = 6, the required number of tickets per day
The Poisson distribution is
$P(k \, tickets/day)=e^{-6.5} ( \frac{6.5 ^{k}}{k!} )$
The distribution is graphed as shown below.

Answer:
The mean is λ = 6.5 tickets per day, and it represents the expected number of tickets written per day.
The required value of k = 6 is less than the expected value, therefore the department's revenue target is met on an average basis.

Answer:

The attached graph shows my answer.

Step-by-step explanation:

The graph has to start at the top because the number of carrots has to decrease and the graph slants down to the right because the time has to increase. Then the situation says that he eats one carrot at a time until half are eaten. The graph shows the line going down until approximately half. Then he doesn't eat any more, so the line is horizontal until the end of the graph to show no change.

Given the function f(c)=4|x-5|+3, for what values of x is f(x)=15?

Tju [1.3M]

All you have to do is plug in 15 to f(x) to get

15=4|x-5|+3 then solve for x
12=4|x-5|
3=|x-5|

3=x-5
-3=x-5

x=8, -2

Hope this helped :)
