Answer:

35/522 ≈ 0.067

Step-by-step explanation:

There are initially 29 names in the hat, 15 of which are girls' names.  So the probability is 15/29.

There are now 28 names in the hat, 14 of which are boys' names.  So the probability is 14/28.

There are now 27 names in the hat, and 14 girls' names.  So the probability is 14/27.

Finally, there are 26 names in the hat, and 13 boys' names.  So the probability is 13/26.

The total probability is:

P = (15/29) (14/28) (14/27) (13/26)

P = 35/522

P ≈ 0.067

AleksAgata [21]
The problem says that the expression (3x + 5)(5x − 1) <span>represents the area of the floor of the building in square meters. Therefore,  to solve this problem you have to follow the proccedure shown below.

 1. First, to simplify the expression (3x + 5)(5x − 1) you must apply the distributive property. Then, you obtain:

 15x</span>²-3x+25x-5

 2. Then, you have:

 15x²+22x-5

 3. As you can see, the correct answer is the last option:  15x²+22x-5
