Mr. Parry needs two students to help him with a science demonstration for his class of 18 girls and 12 boys. He randomly chooses one studentto come to the front of the roomand remain there. He then chooses a second student from those still seated. What is the probability that both students chosen are girls?

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
