Answer:

Simplified form of the expression will be x + \frac{21}{2}

Step-by-step explanation:

The expression is \frac{3(3x+6)}{4}-\frac{(5x-24)}{4}

Now we have to simplify this expression

\frac{3(3x+6)}{4}-\frac{(5x-24)}{4} = \frac{(9x+18)}{4}-\frac{(5x-24)}{4}

= \frac{9x+18-5x+24}{4}

= \frac{4x+42}{4}

= x + \frac{42}{4}

= x + \frac{21}{2}

Therefore, simplified form of the expression will be x + \frac{21}{2}

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.

What is the fraction 2-5 2 on top and 5 on bottom ) equivalent to?
Andrei [34K]

To get to simplest form find the greatest common factor, or the gcf, of both numbers. To do that find all of the factors and find the one with the highest value both numbers share. So 30 would have factors of 1, 2, 3, 5, 6, 10, 15, and 30, and 42 would have the factors of 1, 2, 3, 6, 7, 14, 21, and 42. Both numbers share the factors of 1, 2, 3, and 6 so the gcf is 6. Now divide both numbers by six to get your answer.
