Answer:
16/25 = 0.64
Step-by-step explanation:
18 rolls are ones, so 32 rolls are not ones.
The experimental probability is 32/50 = 16/25 = 0.64.
No, I just took the test,
The answer would be
C. P(solid)22
Cobalt has an atomic number (Z) of 27, which means the nuclei of all its isotopes have 27 protons. Cobalt 60 has an atomic mass of 60, so it has 60-27 = 33 neutrons.
The mass of 27 isolated protons plus the mass of 33 isolated neutrons would be:
27*(1.007825 u) + 33*(1.008665 u) = 60.497220 u
The actual mass of the nucleus of 60-Co is 59.933820 u.
Mass defect: 60.497220 u - 59.933820 u = 0.563400 u
The mass defect is equal to the binding energy of a nucleus.
using the fact that 1 u = 931.5 MeV/c^2
(0.563400 u)*(931.5 MeV/u) = 524.807 MeV
Answer:
the answer would be n+5
Step-by-step explanation:
5n is the same as saying 5 multiplied by n
n +5 would equal the same number
for example if n=2 then 5+2=7
and if we used n+5 it would be 2+5=7
and if you plugin n=2 for all the equations the only correct one is N+5
Answer: 56
Explanation: 28 pounds = 448 ounces
448/8=56
