Answer:
A = 5 ft²
Step-by-step explanation:
the area (A) of a triangle is calculated as
A = bh ( b is the base and h the height ) , then
A = × 5 × 2 ← convert to improper fraction
= ×
=
=
= 5 ft²

Answer:
n=9
Step-by-step explanation:
21/35 has a gcf of 7. so reduce to 3/5
move 3/5 to the left side to get
n/15=-3/5=0
solve as a linear equation.
n/15=-3/5=0 is equivalent to .67*n-0.6=0
which is equal to n=-9
What does the central limit theorem tell us about the
distribution of those mean ages?
<span>A. </span>Because n>30, the sampling
dist of the mean ages can be approximated by a normal dist with a mean u and a
SD o/sqrt 54,
Whenever n<span>>30 the central limit theory applies.</span>
