It's the first one because the other three go pasted -6 which would make the problem not true.
theoretical probability is a coin will land on heads 50% of the time
50% of 100 = 50
since it only landed on heads 38 times, this was less than the theoretical probability of 50

The first two
Step-by-step explanation:
Do the parenthesis of the first and you will get the original equation.
Multiple the second with 4 and you will get the original equation too.
Answer:


Step-by-step explanation:
A) If AB is a diameter, Then ACB is a 90 degrees angle because In a semi-circle (AB is a diameter which divides the circle into 2 equal parts), the angle opposite to the diameter is of 90 degrees.
So, <ACB = 90 degrees
Then <a = 180-90-28
=> <a = 62 degrees
B) The opposite interior angles of a quadrilateral inscribed in a circle add up to 180 degrees.
So,
=> <a + <b = 180
=> <b = 180-62
=> <b = 118 degrees
