Hello,
(-5x-3)(-5x+
3) = (-5x)² - 3²
Answer:
4 times
Step-by-step explanation:
Sample space :
6 sided cube = (1, 2, 3, 4, 5, 6)
Coin = (H, T)
Probability = required outcome / Total possible outcomes
Probability of head (H) = P(H) = 1 /2 = 0.5
Probability of 3 = P(3) = 1 /6 = 0.166666
Probability of heads and 3 on a single try = p(H) * p(3) = 0.5 * 0.166666 = 0.083333
Hence, expected number of times this is likely to occur in 48 tries :
0.083333 * 48 = 4
7.158 * 10^9 rounds to 7 * 10^9
7 * 10^9 = 7,000,000,000
D
uses the the formula y=mx+b and m is the slope. b is the y intercept.
