Here you go take a look at the picture it explain what to do and the answer.
Answer:
mBC = 96°
mB = 55°
mC = 77°
mAB = 154°
Step-by-step explanation:
The angle mB inscribes the arc mAC, so we have:
The sum of internal angles of a triangle is 180°, so in the triangle ABC we have:
Using again the property of inscribed angles, we have:
Confidence interval decreases, error decreases
Option: a
<u>Explanation:</u>
Increasing of sample size will decrease the width of the confidence intervals because it also decreases the standard error of the interval. So whenever the 'sample size' is increases then the 'confidence interval' decreases as well as the 'error' decreases.
Confidence interval gives us the unknown average population or percentage of the population. This gives us just how much the average rate is varying. Confidence interval gives the location as well as the precision of a measure. The smaller sample sizes gives more wider intervals.
Answer:
×= <u>51</u>
7
Step-by-step explanation:
Divide both sides of the equation by –0.182
