The number of boating accidents a policyholder experiences this year is modeled by a Poisson randor with variance 0.10. An insurer reimburses only the first accident. Let Y be the number of unreimbu accidents the policyholder experiences this year. Determine the probability function of Y and find Var(Y)

Step-by-step explanation:

Surface area = lateral area + 2(area of base)

Lateral area = perimeter of base * height.

Because it is a isosceles right triangle, both sides are equal.

= 72

2 = 72. Divide both sides by 2

= 36.  Square both sides.

x = 6.

So the perimeter of the base = 6 + 6 + = 20.485281374239

Lateral area = 20.485281374239 * 7 = 143.397

Area of base is (1/2)base * height.

(1/2)(6)(6) = 18

Using the surface area formula

surface area = 143.397 + 2(18) = 179.4
