The volume of the sphere with a diameter of 12 ft is calculated as: 288π feet cubed.

<h3>What is the Volume of a Sphere?</h3>

The volume of a given sphere with a radius (r) is given as: V = 4/3πr³.

Given the following:

Diameter of the sphere = 12 ft
Radius = 1/2(12) = 6 ft.

Volume of the sphere = 4/3π(6³)

Volume of the sphere = 288π feet cubed

What is the value of (3x^2+1-1-x)(2) ?

Dafna1 [17]

Answer:

6x^2 -2x

Step-by-step explanation:

As written, the constant terms in the first factor cancel each other. The distributive property is used to perform the multiplication:

(3x^2 +1 -1 -x)(2) = (3x^2 -x)(2) = (3x^2)(2) -x(2)

= 6x^2 -2x

makkiz [27]

Answer:

$175

Step-by-step explanation:

let the original price be x

if 1/5 is off the price then the sells is at 4/5

4/5 of x = 140

thus,

4/5* x=140

4x = 140*5

x=700/4

x=$175

Say a hacker has a list of n distinct password candidates, only one of which will successfully log her into a secure system. a.

alexdok [17]

Answer:

The probability is $\frac{1}{n}$

Step-by-step explanation:

If she has n distinct password candidates and only one of which will successfully log her into a secure system, the probability that her first first successful login will be on her k-th try is:

If k=1

$P = \frac{1}{n}$

Because, in her first try she has n possibles options and just one give her a successful login.

If k=2

$P=\frac{n-1}{n} *\frac{1}{n-1} =\frac{1}{n}$

Because, in her first try she has n possibles options and n-1 that are not correct, then, she has n-1 possibles options and 1 of that give her a successful login.

If k=3

$P=\frac{n-1}{n} *\frac{n-2}{n-1} *\frac{1}{n-2} = \frac{1}{n}$

Because, in her first try she has n possibles options and n-1 that are not correct, then, she has n-1 possibles options and n-2 that are not correct and after that, she has n-2 possibles options and 1 give her a successful login.

Finally, no matter what is the value of k, the probability that her first successful login will be (exactly) on her k-th try is 1/n
