Answer:
The value is
Step-by-step explanation:
Generally the number of employee to survey(sample size) is mathematically represented as
Here E is the margin of error which is given as E = 47
So substituting 1.645 for z and 155 for
=>
The kinetic energy is calculated through the equation,
KE = mc²
where KE is kinetic energy, m is mass, and c is the masses. Substituting the known values,
KE = (5 kg)(3 x 10^8)²
KE = 4.5 x 10^17 J
147/x=100/70 (147=100, 70 is from the percent)
(147/x)*x=(100/70)*x
147=1.4285714285714*x
147/1.4285714285714=x
x=102.9 is your answer
