To solve this we use the z statistic. The formula for z
score is:
z = (x – u) / s
where x is the sample value = less than 16, u is the
sample mean = 16.1, s is standard dev = 0.1
z = (16 – 16.1) / 0.1
z = - 1
From the standard distribution tables at z = - 1,
P (z = -1) = 0.1587
<span>So about 15.87% is underweight.</span>
A coefficient goes before a variable and is a constant. When the coefficients are equal but opposite it means you have an even function.
<span>angles A and C are vertical angles

Radius = diameter / 2
radius = 80 / 2 = 40 m
