You do 168+21=189 then you work out what 189 is as % so your answer =18900%
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
I know that the missing angle is 44* but when finding x, a leg and you must find the other side to find ur answer
Step-by-step explanation:
so let's first double the values
12 +12+ 2x-3+2x-3, combine values, we get 4x + 18
lets flip 18 to other side 4x =-18 , we get x =4.5
The mean of the discrete probability distribution is of 1.28.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
Then, considering the given distribution, the mean is given by:
E(X) = 0(0.13) + 1(0.61) + 2(0.15) + 3(0.07) + 4(0.04) = 1.28.
