Answer:
14.14
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(10 - 20)² + (25 - 15)²
√(-10)² + (10)²
√(100) + (100)
√200
= 14.14
Step-by-step explanation:
Did you mean:
= (a - b)(a + b)
= a.a + b.a - b.a - b.b
= a² + ba - ba - b²
= a² - b²

Answer:
998 heads are likely to appear
Step-by-step explanation:
When a fair coin is tossed, the probability to flip a head is 50% and to flip a tail is also 50%, so if the coin is tossed 1996 times, 0.5*1996 = 998 heads and 998 tails are likely to appear, despite the fact the coin lands heads up 4 times before, because every toss is independent of the other ones.
