<span>10% of the 25% of people that prefer to swim on weekends are female.
Multiply 10% and 25% to get 0.025
</span><span> 55% of the 75% are females who prefer to swim on the weekdays.
Multiply them together getting 0.4125
</span>
<span>Divide 0.25 by 0.10= 0.40</span>
Lava I think try that hope it helps :)
Noble Gas Cores have following electronic configuration
He = 1s²
Ne = [He] 2s², 2p⁶
Ar = [Ne] 3s², 3p⁶
Kr = [Ar] 4s², 4p⁶
Xe = [Kr] 5s², 5p⁶
Now solving for question elements,
Germanium = Ge = [Ar] 3d¹⁰, 4s², 4p²
Nickle = Ni = [Ar] 3d¹⁰, 4s²
Tunsten = W = [Xe] 4f¹⁴, 5d⁴, 6s²
Titanium = Ti = [Ar] 3d², 4s²
Iron = Fe = [Ar] 3d⁶, 4s²
Zinc = Zn = [Ar] 3d¹⁰, 4s²
