Answer:
Step-by-step explanation:
Prime numbers are numbers that are divisible by itself and '1'. This means prime numbers are numbers with just two factors while composite numbers are numbers that are divisible by more than two numbers, that is they have more than 2 factors.
Example of prime numbers are 5,7,11 etc. We see that these numbers are only divisible by themselves and by '1' while examples of composite numbers are 10, 15, 20, etc. We clearly see that these numbers have more than 2factors.
Answer:
-8 1/2 ft / min
Step-by-step explanation:
X = second diver rate
1 1/2 X = -12 3/4
3/2 X = - 51/4
X = - 51/4 * 2/3 = - 102/12 = -8 1/2 ft / min
115 is the outlier, and it results in the mean being lower than it would have been.
You're going to want to take the total, which is $353.00 and subtract the initial cost, which is $84.00, the number now should be $269. Using that total divide it by $68.00, there you should find your answer of about 4 hours. The precise answer is 3.99588235. But you would round that to 4 hours.
