<span>-3 + 4y = 12
4y = 12+3
4y = 13
y = 13/4
So y-intercept is </span>13/4
Answer:
this is a right angled triangle
so by the Pythagoras theorem
h2 = √ p2+. b2
h2 = √2 square + 6 square
h2 = 4+ 36
h2 = 40
h = √40
h = 20
Sounds like you're asked to find
such that
In other words, find
that satisfies
We can factorize this as
In order that
describes a probability distribution, require that
for all
, which means we can ignore the possibility of
.
Let
.
Multiply both sides by
.
We want to find
that removes the quartic and quadratic terms from the equation, i.e.
so the cubic above transforms to
Substitute
and we get
