2/5 or 40 percent

Step-by-step explanation:

All we need to solve this problem are the total number of boys and the total number of girls. Since we already know how many boys there are (6) , let's start by finding the girls, which is marked as b. Looking at the chart, we can tell that

8 + a = b

but we don't know what a is yet. How about we find that out first? If we look vertically, we can see that

a + 4 = 5

so

a = 1.

Now, we can find b.

b = 9

To find the probability of selecting a boy, we have to divide the number of boys by the total number of people.

boys/total = 6 / 15

Simplifying, we get the answer

2/5.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
