I got 30, I’m not sure if it’s correct or not.
Answer:
<h2>69.5</h2>
Step-by-step explanation:
Given the confidence interval of the heights of american heights given as (65.3,73.7);
Lower confidence interval L = 65.3 and Upper confidence interval U = 73.7
Sample mean will be the average of both confidence interval . This is expressed mathematically as 
Hence, the sample mean is 69.5
1: 144 because
4 * 15 = 60 ft total height = 720 in total height
5: 720 = 1: 144
Remark
The diameter of the circle is AC. The hypotenuse of the right triangle is also AC. This assumes that A,B and C all lie on the circumference of the circle.
Answers
One
The center of the circle is on the diameter of the circle. In fact, the center bisects the diameter. So the center lies on AC and if the center is labeled O then AO = BO.
<em><u>Answer 1: </u></em> AC
Two
The answer is the single word diameter.
The answer is: [C]: " 1200 m³ " .
