Answer: B. 1/2(y - 116) = 64

Step-by-step explanation:

Since, we know that,

The angle formed by two tangent = $\frac{1}{2}(\text{Difference of intercepted Arcs} )$

= $\frac{\text{major arc - minor arc}}{2}$

Here, Major arc = y°

Minor arc = 116°

And, Angle made by two tangents YX and YZ,

$m\angle XYZ = \frac{\text{y - 116}}{2}$

$64 = \frac{\text{y - 116}}{2}$ ( because, $m\angle XYZ = 64^{\circ}$ )

⇒ $\frac{\text{y - 116}}{2} = 64$

Which is the required equation to find y, the measure of XWZ.

Thus, Option B is correct.

Answer:

B. 1/2(y - 116) = 64

Step-by-step explanation:

<y = 1/2 (zwyx - zx)

64 = 1/2 (y-116)

The sutton police department must write, on average, 6 tickets a day to keep department revenues at budgeted levels. suppose the

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.
