H is the altitude of a right triangle, so h²=AD*DC=(20-4)*4=64
h=√64=8
D is the correct answer.
There is 2 red fives in a deck ( Hearts and Diamonds) and 2 red fours, for a total of 4 possible cards.
This would give a probability of 4/52, which reduces to a 1/13 probability.
Range means highest value minus lowest value in a data collection
highest value = 18
lowest value = 2
Range = 18-2 = 16
Answer:
1. Formula: b * h ÷ 2
12 * 3 = 36 ÷ 2 = 18 in^2
2. Formula: b * h ÷ 2
5 * 8 = 40 ÷ 2 = 20 ft^2
I could only help on two. Hope it helps though! =)
