A bag contains 4 blue coins and 8 red coins. A coin is removed at random and replaced by three of the other color.

1 answer:

6 0

the answer is 11/14 because you remove one blue coin and add three red coins and in total in the bag there are 14 coins. you then create a fraction by putting the 11 red coins over the 14 total coins to get the probability of what you will get

The answer is 11/14

Finger [1]

Answer:

x= 9

Step-by-step explanation:

Move the terms -> -1=14x = -12x + 16

Find out the sum -> 2x=17+1

Divide both by the equation by two -> 2x=18 x=9

Using the recursion equation, it is found that the value of the 2nd iterate is:

$x_2 = 3.16228$

<h3>What is the recursive equation?</h3>

The value of the nth iteration is given by:

$x_n = \frac{x_{n-1} + \frac{10}{x_{n-1}}}{2}$

The initial estimate is:

$x_0 = 3.1$

Hence, the 1st iterate is given by:

$x_1 = \frac{x_0 + \frac{10}{x_0}}{2} = \frac{3.1 + \frac{10}{3.1}}{2} = 3.1629$

The 2nd iterate is:

$x_2 = \frac{x_1 + \frac{10}{x_1}}{2} = \frac{3.1629 + \frac{10}{3.1629}}{2} = 3.16228$

Thus, the fourth option is correct.
