This is a true statement. Here's how we know. The factors of that general formula are (ax - b)(ax - b). If that is in fact the general formula of the quadratic shown, then our a would be 2 and our b would be 3, since 2 times 2 is 4 which is the leading coefficient, and 3 times 3 is 9 which is the constant. Those factors, filled in accordingly, would be (2x - 3)(2x - 3). If we FOIL those out we should get back the quadratic in question. FOILing gives us
which of course simplifies to

➷ (12/20) = 0.6
(8/20) = 0.4
The experimental probability of the coin landing heads up is 0.6.
B) The theoretical would be considering it a fair coin.
1/2 = 0.5
The theoretical probability would be 0.5

Answer:
7
Step-by-step explanation:
because 1 = 400
2800 divided by 400 = 7
6 to the power of 2 is 6 multiplied by six which is 36
then 13 + 39 is 52 - 2 = 50- 10 = 40 - 36= the answer 4
