Answer:
Step-by-step explanation:
Its c.
If you will substitute those numbers to the pair of equations, both will be true.
1=-3+4
1=3-2
First, find all the factors of the two numbers (separately):
<span>72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72
</span>48: <span>1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The numbers in bold are factors of both 72 and 48.
Find the greatest one (out of the numbers in bold). 24 is the GCF.</span>
Answer:605
Step-by-step explanation: you multiply 550 x .10 and that will get you 55. You add that to 550 and the answer is 605.
Answer:
2.35%
Step-by-step explanation:
First, calculate the difference between mean and the months in the problem:
first month :59 – 26 = 33
second motnh: 59 – 37 = 22
Since standard deviation is 11 months, for the first month is a difference of 3 standard deviation and for the second is 2 standard deviation.
the 68-95-99.7% rule establish that:
1 standard deviation means a 68% of total area under the normal distribution. On one side is half = 34%.
2 standard deviations means a 95% of total area under the normal distribution. On one side is half = 47.5%.
3 standard deviation means a 99.7% of total area under the normal distribution. On one side is half = 49.85%.
The difference between 3 and 2 standard deviation is
49.85 – 47.5 = 2.35%
The answer is 2.35% of cars that remain in service between 26 and 37 months
