I sort the data from the lowest 17.7, 18.3, 19.2, 21.1, 21.7, 23.2, 23.4, 23.7, 25.8, 26.2, 27.3, 27.4, 29.4, 29.8, 31.6, 33.5, 37.7, 38.9, 44.9
Then I classify the data to the appropriate class 1) Class 15.0-20.9 There are 3 data, those are 17.7, 18.3, and 19.2 2) Class 21.0 - 26.9 There are 7 data, those are 21.1, 21.7, 23.2, 23.4, 23.7, 25.8, 26.2 3) Class 27.0 - 32.9 There are 5 data, those are 27.3, 27.4, 29.4, 29.8, 31.6 4) Class 33.0 - 38.9 There are 3 data, those are 33.5, 37.7, 38.9 5) Class 39.0 - 44.9 There is 1 data, that is 44.9
SUMMARY BMI Class and frequency 15.0 - 20.9 ⇒ frequency 3 21.0 - 26.9 ⇒ frequency 7 27.0 - 32.9 ⇒ frequency 5 33.0 - 38.9 ⇒ frequency 3 39.0 - 44.9 ⇒ frequency 1
<span>a.
The radius of earth is about 6400 kilometers. Find the circumference of
a great circle.
Circumference = 2π(radius) = 2π(6400 km) = 40.212,39 km
b. Write an equation for the circumference of any
latitude circle with angle theta
As stated, </span><span><span>the
length of any parallel of latitude (this is the circumference of corresponding circle) is equal to the circumference of a
great circle of Earth times the cosine of the latitude angle</span>:
