There are 60 minutes in an hour and percent means per one hundred so:
p/100=18/60
p=1800/60
p=30%
Answer:
Part A
The given numbers are 14.25 and 0.86
By multiplying the two numbers, we have;
14.25 × 0.86 = 12.255
By adding the two numbers, we have;
14.25 + 0.86 = 15.11
Therefore, addition gives the greatest solution because one of the number is a fraction less than one
Part B
By dividing the two numbers (Dividing the larger number, 14.25 by the smaller number 0.86), we have 14.25/0.86 ≈ 16.57
Therefore, dividing the larger number by the smaller fraction gives a solution larger than the solution found in part A because the larger number multiplied by (1 - the inverse smaller fraction number) is larger than the value of the smaller (fraction) number
Step-by-step explanation:
Answer:
And using the cumulative distribution function we got:
The probability that preparation is within 2 minutes of the mean time is 0.134
Step-by-step explanation:
For this case we define the following random variable X= (minutes) for a lab assistant to prepare the equipment for a certain experiment , and the distribution for X is given by:
The cumulative distribution function is given by:
The expected value is given by:
And we want to find the following probability:
And we can find this probability on this way:
And using the cumulative distribution function we got:
The probability that preparation is within 2 minutes of the mean time is 0.134
