Answer:
Step-by-step explanation:
The area of the circumference of a circle is:
We know that r is 8, so we can plug that into the formula.
However, there's a problem. We only want 3pi/4 of the circumference, not the entire circle's circumference. Therefore, we have to divide by part/whole. In this case, the part is 3pi/4, and the whole is 2pi (the entire circle is 2pi radians).
Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The population proportion is
The mean of the sampling distribution is
The sample size is n = 600
Generally the standard deviation is mathematically represented as
=>
=>
Generally the probability that the proportion of airborne viruses in a sample of 600 viruses would differ from the population proportion by greater than 3% is mathematically represented as
=>
Now add p to both side of the inequality
=>
=>
Now converting the probabilities to their respective standardized score
=>
=>
=>
From the z-table
and
So
=>
