Answer:

Step-by-step explanation:

Probabilities greater than 1/5

1 ) choosing 1 red marble = 3 / 10 which is greater than 1 / 5 .

2 ) choosing 1 white marble, replacing it, and choosing another white marble

choosing 1 white marble = 5/ 10 = 1 / 2

choosing white marble next time = 1 / 2

choosing 1 white marble, replacing it, and choosing another white marble

1 / 2 x 1/2 = 1/4 which is more than 1/5

3 ) choosing 1 white marble 5 / 10

= 1 /2 which is more than 1 / 5 .

What is the value of x?

Juli2301 [7.4K]

Answer:

x = 3 sqrt 2

Step-by-step explanation:

We know that this is a 45, 45m 90 special right triangle. In this special right triangle the side lengths are x, x and the hypotenuse is x sqrt 2 (we can prove this using pythagoreans theorem). 6 is the hypotenuse, meaning that it is equal to x sqrt 2:

6 = x sqrt 2

x = 6/sqrt 2

Rationalize the denominator:

x = (6 sqrt 2)/2

x = 3 sqrt 2

How do you calculate the volume of a cone when given the height and diameter describe the steps used to solve

SpyIntel [72]

The photo is an example.
Divide the diameter by 2 to get the radius.
Then times 1/3 time Pi times the radius squared times the height.
The formula is V=1/3(Pi)(radius squared)(height)

Answer:

Answer for the question:

To compute a19 mod N, the modular exponential algorithms that we studied would do 8 modular multiplications (5 squarings and 3 multiplications by a). What is the minimum number of modular multiplications needed to compute a19 mod N if you are free to use any sequence of modular multiplications.)
