Answer:

The amount of string needed is 25.1 inch.

Step-by-step explanation:

The amount of string needed to go around is equal to the circumference of that area. As the bottom of cone is to go around by string, the circumference will provide us with the right amount.

           radius (r) = 4 inch.

                      π = 3.14

circumference of circle (C) = 2πr

                                          = 2 *π *r

                                          = 2 *3.14 *4

                                          = 25.1 inch.

Hence 25.1 inch string will go around the cone easily.

Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following p
strojnjashka [21]

Answer:

P(X = 3) = 0.14680064

Step-by-step explanation:

Formula=============================

p\left( X=k\right)  =C^{k}_{n}p^{k}(1-p)^{n-k}\ \ ;\ k\in \left\{ 0,\ldots ,n\right\}

……………………………………………………………………..

Given :

n = 8

p = 0.2

1 - p = 1 - 0.2 = 0.8

k = 3

Then

p\left( X=3\right)  =C^{3}_{8}(0.2)^{3}(0.8)^{5}

               =0.14680064
