Heights of young adult women in the United States are approximately Normal with a mean of 64 inches and standard deviation 2.7 inches. What proportion of all young adult women in the United States are taller than 6 feet

The proportion of all young adult women in the United States are taller than 6 feet(72 inches ) is  

Step-by-step explanation:

From the question we are told that

   The mean is  

    The standard deviation is  

Generally  6 feet  is equivalent to 6 * 12 = 72 inches

Generally the proportion of all young adult women in the United States are taller than 6 feet(72 inches ) is mathematically represented as

From the z-table

  The area under the normal  curve to the right corresponding to 2.963  is  

=>  

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

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
