Six samples of each of four types of cereal grain grown in a certain region were analyzed to determine thiamin content, resulting in the following data (µg/g): Note: If you want to use R this data has been set up so you may copy it directly into R. Wheat=c( 5.3, 4.6, 5.9, 6.2, 6.8, 5.8) Barley=c( 6.5, 8.0, 6.2, 7.5, 6.0, 5.6) Maize=c( 5.9, 4.6, 6.4, 4.9, 6.1, 5.3) Oats = c( 8.3, 6.0, 7.7, 7.0, 5.6, 7.2)

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
