Answer:
5
Step-by-step explanation:
Given :
Observed values = 5, 10, 15
Expected freqencies = 10
χ² = Σ(observed - Expected)² / Expected
χ² = (5-10)²/10 + (10-10)²/10 + (15-10)²/10
χ² = 25/10 + 0/10 + 25/10
χ² = 2.5 + 0 + 2.5
χ² = 5
Answer:
Volume of cylindrical tank is 2122.64 cubed feet.
Step-by-step explanation:
It is given that:
Radius of cylindrical tank = 6.5 feet
Height of tank = 16 feet
Volume of tank = πr²h
Putting the values in the formula
Volume = 3.24 * (6.5)² * 16
Volume = 3.14 * 42.45 * 16
Volume = 2122.64 cubed feet.
Therefore,
Volume of cylindrical tank is 2122.64 cubed feet.
You can write it in expanded form as 100+40+9+.06

Let the interior angle be x.
x/(180-x) = 13/2
2x= 2340-13x
15x=2340
x=156
exterior angle= 180-156=24
Number of sides=360/24=15
