A certain flight arrives on time 89 percent of the time. Suppose 133 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that
(a) exactly 125 flights are on time.
(b) at least 125 flights are on time.
(c) fewer than 117 flights are on time.
(d) between 117 and 123, inclusive are on time.

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.
