Both pairs of vertical angles<span> (four </span>angles<span> altogether) always sum to a full </span>angle<span>(360°). In the figure above, </span>an angle<span> from each pair of </span>vertical angles<span> are adjacent</span>angles<span> and are </span>supplementary<span> (add to 180°). For example, in the figure above, m∠JQL + m∠LQK = 180°.</span>
Divide total dollars by total pounds:
$35 /5 = $7 per pound
Answer: $7
Answer:
(t^2 -4) (t^2 +4)
(t-2)(t+2)(t^2+4)
Step-by-step explanation:
t^4 - 16
We can write this as the difference of squares
We know the dfference of squares is
(a^2 - b^2) = (a-b) (a+b)
( t^2 ^2 - 4^2) = (t^2 -4) (t^2 +4)
We can write t^2 -4 as the difference of squares
t^2 -4 = t^2 -2^2 = (t-2)(t+2)
Replacing this in
( t^2 ^2 - 4^2) = (t^2 -4) (t^2 +4) = (t-2)(t+2)(t^2+4)
Based on the emperical rule
the distribution will be as follows
btwn 80 n 85 on the test - 34%
btwn 80 n 95 on the test - 82%
below 85 on the test - 50%
<span>above an 80 on the test - 84%</span>
