Answer:
When we know all 3 sides, we use Heron's Formula
area = sqrt [s *(s-a) * (s-b) * (s-c)]
where "s" is the semi-perimeter which in this case equals
s = (6 + 8 + 12) / 2 = 13
area = sqrt [13 * 5 * 7 * 1]
area = sqrt 455
area = 21.3307290077
area = 21.33 square feet (rounded)
Step-by-step explanation:
Answer:
So trapezoid is 1/2(a+b) × h
So 1/2(16)(6)× (12)

If , then events A and B are independent, otherwise they are dependent.
Find the probabilities:
1.
2.
3. .
Now, since , you can state that events are independent and correct choice is A.
Answer:
C. Equally likely
Step-by-step explanation:
1/2=0.5=50% probability
