Answer:
2.45
Step-by-step explanation:
0.7 times 3.5 = 2.45
A research paper recommends using Poisson process to model the number of failures in commercial water pipes The paper also gives estimates the failure rate in units of failures per 100 miles of pipe per day; for four different types of pipe and for many different years_ For example, for cast iron pipe in 2005, the authors' estimate is the failure rate is 0.0864 failures per 100 miles per day: Suppose a town had 2500 miles of cast iron pipe underground in 2005 What is the probability of at least two failures
Answer:
B is the only solution
Step-by-step explanation:
These inequalities are shown in the attached picture. Which can be obtained drawing y > -2 (an horizontal line at y=-2, the region is above). and y<= 4-x, a line with a negative slope of -1 and intercept point of 4.
Any ordered pair, located inside the interception between these two regions is a solution of the system.
A. is Outside, below the horizontal line
B. is not clear by graph, hence, lets evaluate it in both inequalities
3>-2 (satisfies)
1+3<=4 (satisfies)
Hence B is a solution.
C. Is outside, we can evaluate it just to make sure:
5>-2 (satisfies)
1+5<= 4 (not true)
Hence C is not a solution.
D. is outside
