Sqrt P = 2
Square both sides;-
(sqrt P)^2 = 2^2
P = 4 Answer
Angle sum is the sum of all angles (exterior and interior) while interior angle sum is sum of all interior angles.
For example a square has an interior angle sum of 90° + 90° + 90° + 90° = 360° since all his interior angles measure 90° and there are only 4 of them.
It's total sum of angles is much bigger (interior + exterior angle sum)
The exterior angle sum of an square is 4 × (360 - 90°) = 1080° and you must add the interior angle sum which is 360° so we have 1080° + 360° = 1440° and that is the total angle sum.
As you can see the interior and total sum of angles are different in size and therefore are a different things.
Hope this helps.

Answer:
a. $ 1.11
b. $ 0.08
Step-by-step explanation:
a. The volume of the ball is the volume considering all it (1.2 in diameter) less the volume considering the 0.4 in thick.
V = (4/3)πrb³ - (4/3)πrt³
Where rb is the radius of the ball (0.6 in) and rt is the thick (0.4 in)
V = (4/3)π(0.6)³ - (4/3)π(0.4)³
V = 0.637 in³
For 50 balls, the volume is 50*0.637 = 31.85 in³
So, the cost to produce 1 case is:
$0.035/in³ * 31.85 in³ = $ 1.11
b. The profit is the difference between sales and cost, so for one ball:
P = 0.10 - 0.035*0.637
P = $ 0.08
Higher standard deviation shows a greater spread of the data.
2005 - sd=3.5
2006 - sd=2.8
2007 - sd=1.0
2008 - sd=4.0
The correct statement is the last statement which says the game scores of season 2005 have a greater spread than the game scores of season 2006
