Liz flips a coin 50 times. The coin lands heads up 20 times and tails up 30 times. Complete each statement The theoretical probability of the coin landing heads up is %. (Type an integer or a decimal) A​

Explanation:

Assuming we have a fair coin, there's a theoretical 50% chance of getting heads. This is because 1/2 = 0.50 = 50%

This is in contrast to the empirical probability Liz gets which is 20/50 = 0.40 = 40%. The empirical probability is often different from the theoretical probability; however, the two should be fairly close. The empirical probability should also get closer to the theoretical one as you do more trials. For more info, check out the law of large numbers.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
