Given:
Pool swimming Ocean swimming Total
Age 30 and younger 228 54 282
Over 30 years old 142 185 327
total 370 239 609
Frequencies:
Pool swimming Ocean swimming Total
Age 30 and younger 228/609 = 0.37 54/609 = 0.09 282/609 = 0.46
Over 30 years old 142/609 = 0.23 185/609 = 0.30 327/609 = 0.54
<span>total 370/609 = 0.61 239/609 = 0.39 609/609 = 1.00</span>
<span>The relative frequency (rounded to the nearest hundredth) of a person over 30 years old who prefers to swim in the ocean is 0.30</span>
The formula for this is I = PRT
I = Interest
P = Principal (starting amount) = $50,000
R = Rate (percentage) = 8% = .08
T = Time in years = days/years = 111/365
I = 50000(.08)(111/365)
I = $1216.438
I = $1216.44 (rounded)

Answer:
The volume of the hemisphere
V = 121.33086 cubic centimeter
Step-by-step explanation:
<u>Step(i)</u>:-
Given that the total surface area of a hemisphere = 45π cm²
<em> The total surface area of a hemisphere = 3π r²</em>
Equating
3π r² = 45π

r = 
The radius of the sphere 'r' = 3.87
<u><em>Step(ii):-</em></u>
<em>The volume of the hemisphere</em>


we know that π = 3.14

V = 121.33086 cubic centimeter
