We are given that:
2x + 3 = 5x - 3

We will solve the given to get the value of x as follows:
2x + 3 = 5x - 3
3 + 3 = 5x - 2x
6 = 3x
x = 6/3
x = 2

Now, we will check te given set to see if 2 belongs to the set or not. We will find that 2 is an element in the given set.

Therefore, the correct choice is:
A) {2}

hope this helps :)

Question 7 A number cube with faces labeled from 1 to 6 will be rolled once. The number rolled will be recorded as the outcome.
QveST [7]

Answer:

1) S=\{1,2,3,4,5,6\}

2) O=\{1,3,5\}

Step-by-step explanation:

Given : A number cube with faces labeled from 1 to 6 will be rolled once. The number rolled will be recorded as the outcome.

To find : Give the sample space describing all possible outcomes. Then give all of the outcomes for the event of rolling an odd number. If there is more than one element in the set, separate them with commas ?

Solution :

A number cube with faces labeled from 1 to 6 will be rolled once.

The sample space describing all possible outcomes is given by

S=\{1,2,3,4,5,6\}

All of the outcomes for the event of rolling an odd number is given by

O=\{1,3,5\}

A bag contains n blue and m red marbles. You randomly pick a marble from the bag, write down its color, and then put the marble
Oksana_A [137]

Answer:

(mn+n²)/(m+n)

Step-by-step explanation:

probability of blue marble= n/(n+m)

probability of red marble= m/(n+m)

probability that process stops = Probability of both blue + probability of both red=  n/(n+m) × n/(n+m) + m/(n+m)×m/(n+m)

                        = (n²+m²)/(n+m)²

P(1st marbel is blue)= P(blue and red) + P(blue and blue)

                                  = mn/(n+m) + n²/(n+m)

                                   = (mn+n²)/(m+n)

P(1st marble is blue | process stops)= ( (mn+n²)/(m+n)× (n²+m²)/(n+m)²)/ ((n²+m²)/(n+m)²)

= (mn+n²)/(m+n)
