Answer:
1 2 3
Step-by-step explanation:
We have been given a diagram. We are asked find the measure of arc EAB.
First of all, we will find the measure of arcs ED and CB using our given information.
We know that measure of an inscribed angle is half the measure of intercepted arc.
We can see that angle EBC is inscribed angle of arc EDC, so measure of arc EDC will be twice the measure of angle EBC.



Similarly, we will find the measure of arc DCB.











Therefore, the measure of arc EAB is 148 degrees and option C is the correct choice.
Answer:
Depends on the type of rope but I would say feet
Step-by-step explanation:
Answer:
81.86%
Step-by-step explanation:
We have been given that final exam scores are normally distributed with a mean of 74 and a standard deviation of 6.
First of all we will find z-score using z-score formula.
Now let us find z-score for 86.
Now we will find P(-1<Z) which is probability that a random score would be greater than 68. We will find P(2>Z) which is probability that a random score would be less than 86.
Using normal distribution table we will get,

We will use formula
to find the probability to find that a normal variable lies between two values.
Upon substituting our given values in above formula we will get,


Upon converting 0.81859 to percentage we will get

Therefore, 81.86% of final exam score will be between 68 and 86.
Answer:
Option B 1.5 min
Step-by-step explanation:
we know that
1 mi=1,609.36 m
1 h=60 min
so

using proportion
