<span>(x + 2)</span>·<span>2 = a
(1 + 2)</span>·2 = a
3·2 = a
a = 6
First, add all the numbers together, which is 68. Then divided 100 by 68, which gives you the number 1.47, and that's your answer.
The correct answer would be choice A: 1.
When 3 coins are flipped, there are 8 possible outcomes.
0 Tails = 1 ways
1 Tails = 3 ways
2 Tails = 3 ways
3 Tails = 1 ways
If you add up all the different tails, you could get 12 tails. Divide 12 by 8 and you have 1.5 which is the average number of tails you could expect to get by flipping 3 coins.
Your answer is D because his line needs to be slightly above +25 each time 50+25=75 so his line would be above 75
Average speed is the total distance traveled by an object at a certain period of time. To calculate for the average speed we divide the total distance covered by the total time. We do as follows:
Average speed = 560 meters / 25 seconds = 22.4 m/s
