Since they are multiples if 12
The possibilities are
12, 12, 156
12,24,144
12,36,132
12,48,120
12,60,108
12,72,96
12,84,84
24,24,132
24,36,120
24,48,108
24,60,96
24,72,84
36,36,108
36,48,96
36,60,84
36,72,72
48,48,84
48,60,72
60,60,60
Hence the probability is 1/19 or 0.0526
Answer:D
Step-by-stepA explanation: if you simply the fraction by 4/15. The answer is 0.26
The solution is equal to both numbers.
<em>≈ 63.30 ft²</em>
- Step-by-step explanation:
<em>Heron formula</em>
<em>A = √p(p - a)(p - b)(p - c)</em>
<em>a = 9 ; b = 15 ; c = 20</em>
<em>p = (a + b + c)/2 = (9 + 15 + 20)/2 = 44/2 = 22</em>
<em>A = √22(22-9)(22-15)(22-20)</em>
<em>= √22×13×7×2</em>
<em>= √4004</em>
<em>≈ 63,27</em>
<em>≈ 63.30 ft²</em>
You have to add all the numbers then divide by how many there are, the mean is 3.4
