P(5 on one throw) = 1/8
expected number of 5's in 400 throws = 1/8 * 400 = 50

remove first set of parentheses:
apply "-" sign to second parentheses (distributive prop):
the - of a - becomes a + :
combine like terms:
Factor out the variables that are alike:
{(1)a^4 + (-6)a^2 + 0a + (-8)}}}
0a is just 0, makea the "a" term go away:
can try to factor as squares, but it doesn't work out:
8 = (-4) x (+2) product factors cannot add to make 6. </span>
The distance between two points A(x₁,y₁) and B(x₂,y₂) will be:
dist (A,B)=√[(x₁-x₂)²+(y₁-y₂)²]
In this case:
V(-2,5)
M(0,-4)
dist (V, M)=√[(-2-0)²+(5+4)²]=√(4+36)=√40
Answer: the distance between this points would be √40 u
u=units of distance.
Answer:
The answer would be 0.99/1 pound
