Answer:
Volume = (250π√3)/3 unit³
Step-by-step explanation:
The shape is a solid sphere
Where rho = ρ
ρ ≤ 5
Where Phi = φ
φ = π/6 (lower limit)
φ = 5π/6 (upper limit)
Note 1π rad = 180°
We would apply triple integrals and spherical coordinates to solve for the volume of a solid sphere.
See attachment for details
From calculations,
The volume of the portion of solid sphere = Volume = (250π√3)/3 unit³
Answer:
Step-by-step explanation:
Here X the no of children suffering from hookworm treated and recovered is binomial because
a) Each child is independent of the other
b) There are only two outcomes
c) The probability for any child to recover is constant as 90% = 0.9
X is Bin (20,0.9)
a) Prob that all 20 will be cured
=P(X=20)=
b) Prob all but 1 will be cured=
c) Prob exactly 18 will be cured
d) Prob exactly 90% will be cured.
