The surface area is 47.1 sq in.

Step-by-step explanation:

Given,

The height (h) of the coin (cylinder shaped) = 5 inches

The radius (r) = 1.5 inches

To find the surface area of the coin.

We need to find the lateral surface area of the coin.

Formula

The surface area of the coin of radius r and height h is 2πrh.

Now,

Putting the value of h and r and π=3.14 we get,

Area = 2×3.14×1.5×5 sq inches

= 47.1 sq in

Hence, the surface area is 47.1 sq in.

An insurance company models the number of warranty claims in a week on a particular product that has a Poisson distribution with

lapo4ka [179]

Answer:

4 monetary units

Step-by-step explanation:

In a Poisson distribution, the expected value of the distribution is the same as the mean:

$E(X)=\mu=4\ claims$

The expected number of warranty claims is 4.

Since each claim results in a payment of 1, the expected value paid by the insurer is:

$E(V)=E(X)*V(X)\\E(V)=4*1 = 4$

The expected total payment on warranty claims is 4 monetary units.
