Kryger [21]

Answer:

<h2>√126</h2>

Option D is the right option.

solution,

\frac{ac}{bc}  =  \frac{bc}{dc}  \\ or \:  \frac{18}{ m}  =  \frac{m}{7}  \\ or \: m \times \: m = 18 \times 7(cross \: multiplication) \\ or \:  {m}^{2}  = 126 \\ m =  \sqrt{126}

Hope this helps..

Good luck on your assignment.

An insurance company has 10,000 automobile policyholders. The expected yearly claim per policyholder is $240, with a standard de
elena55 [62]

Answer:

almost 0%

Step-by-step explanation:

Given that for an insurance company with 10000 automobile policy holders, the expected yearly claim per policyholder is $240 with a standard deaviation of 800

using normal approximation, the probability that the total yearly claim exceeds $2.7 million is calculated as follows:

Sea sumatoria de x = SUMX, tenemos que:

P (SUMX \geq 2700000) = P(\frac{SUMX - 240*10000}{800 *\sqrt{10000} } \geq \frac{2700000 - 240*10000}{800 *\sqrt{10000} })

= P (z\geq \frac{2700000 - 240*10000}{800 *\sqrt{10000}})

= P (z => 3.75)

= 1 - P ( z < 3.75)

P = 1 - 0.999912

P = 0.000088

Which means that the probability is almost 0%
