Answer:
13.5 mg
Step-by-step explanation:
Here given Cobalt isotope has half life of 5.3 years.
Initial amount is 50 mg.
Given time(10 years) is roughly equals to two half life.
So, after 5.3 year 25 mg of isotope will left further in next half life only around 12.5 mg remains.
Among options 13.5 mg is the best possible
Answer:
The probability that more than half of the sample would vote for him is P=0.7549.
Step-by-step explanation:
With a sample size of n=300, we can approximate this to the normal distribution.
The parameters will be
We have to calculate the probability that half or more of the sample vote for him. This is P(x>150).
To calculate this probability, first we calculate the z-value:
Then
The probability that more than half of the sample would vote for him is P=0.7549.
