If you subtract Betty's time for the swim, 27.948 seconds, from Nancy's time, 28.004 seconds, you will find that Betty was faster than Nancy by 0.056 seconds. She would be considered the winner of the 50-meter freestyle swim.
Answer:
Step-by-step explanation:
Given that a cheese can be classified as either raw dash milk or pasteurized. Suppose that 91% of cheeses are classified as pasteurized.
Each cheese is independent of the other and there are only two outcomes.
Hence X = no of cheeses pasteurized is binomial (2,0.91)
a) P(x=2 ) when n=2 is
b) n=6.
P(x=6) =
c) P(atleast one raw dash milk) = 1-P(all pasteurised)
=0.8281
Since probability is 0.83 it is not unusual.
The problem should be 7.5=3k. So that means that you have to divide both sides by 3. Once you do that you should get 2.5 as your answer.
Since it is already an equation you will multiply A and C (2 and -15) and get -30. You will then find which two numbers multiply to get -30 and add to get -1.
