A survey conducted by the Harris polling organization discovered that 63% of all Americans are overweight. Suppose that the 30 adults in a particular office are
weighed.

a) Determine that this particular setting is a BINOMIAL SETTING.

b) Find the probability that exactly 18 members of the class are overweight.

c) Find the probability that no more than half of the class members were overweight.

d) Find the probability that more than 2/3 of the class members are overweight.

for a it would be 24 children.

step-by-step explanation:

the answer is b.6

step-by-step explanation:

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
