Since the bases are the same you can subtract the exponents. All you have to do is 5-2, which is 3 therefore the answer is x^3.

(Photo above! How would I find the area of this?

boyakko [2]

It is basically a square attached by a small rectangle. So figure out the area of the square and add it to the area of the rectangle and don't forget to label your answer. Hope this helped :)

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

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%

The area of the base (six triangles with a base 15m and a height 7.5√3m):

$A_B=6\cdot\dfrac{1}{2}\cdot15\cdot7.5\sqrt3\approx585\ m^2$

The area of side walls (six triangles with a base 15m and a height 12m)

$A_W=6\cdot\dfrac{1}{2}\cdot15\cdot12=540\ m^2$

The surface area:

$A_B+A_W=585+540=1,125\ m^2$
