Answer:
Step-by-step explanation:
This situation can be modeled by a binomial distribution of parameters:
We want to find the probability that at least 90 are in repair.
<u><em>We can approximate this problem to a normal distribution, where:</em></u>
Then we look for
Then we must find the normal standard statistic Z-score
Therefore:
Looking in the standard normal table we obtain:
∠ROT=160°
∠SOT=100°
Now ∠SOR= ∠ROT - ∠SOT
∠ SOR = 160°-100°
∠ SOR =60°
It is given that measure of angle ROQ to equals the measure of angle QOS equals the measure of angle POT.
∠SOQ + ∠QOR = 60°
But ∠SOQ = ∠QOR
2∠SOQ=60°
∠SOQ=60°÷2
∠SOQ =30°
Also ∠POT=∠SOQ=∠ROQ=30°
