12.4% of 153,000 : some college, no degree
0.124(153,000) = 18,972
84.1% of 153,000 : bachelor's degree or higher
0.841(153,000) = 128,673
128,673 - 18,972 = 109,701 <==
The conditional and its converse are true, and the biconditional is
An angle is a right angle if and only if its measure is 90.
The area of a parallelogram is the base times the height.
Area and base is given so we can use that to solve for the height:
72 = 6* h
h = 72/6
h = 12
The height is 12 units.
For
(x-h)^2=4p(y-k)
vertex=(h,k)
p=vertical distance from vertex to directix
when p is negative, the directix is above the vertex
when p is positive, the directix is below the vertex
(x-2)^2=1/4(y+3)
(x-2)^2=4(1/16)(y+3)
p=1/16
it's positive so we know directix is below vertex
vertex is (2,-3)
go 1/16 down
-3-1/16=-48/16-1/16=-49/16
directix is y=-49/16 aka y=-3.0625
