Answer: Second option.
Step-by-step explanation:
The slope of a line can be calculated with this formula:
Then, you need to choose two points of the line shown in the graph and substitute them into the formula for calculate the slope:
Let's pick the points (-4,4) and (4,-2).
Substituting:
![m=\frac{-2-4}{4-(-4)}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-2-4%7D%7B4-%28-4%29%7D)
Simplifiying, you get that the slope of the line in the graph is:
![m=\frac{-2-4}{4-(-4)}\\\\m=\frac{-6}{4+4}\\\\m=\frac{-6}{8}\\\\m=-\frac{3}{4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-2-4%7D%7B4-%28-4%29%7D%5C%5C%5C%5Cm%3D%5Cfrac%7B-6%7D%7B4%2B4%7D%5C%5C%5C%5Cm%3D%5Cfrac%7B-6%7D%7B8%7D%5C%5C%5C%5Cm%3D-%5Cfrac%7B3%7D%7B4%7D)
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:
i got 1200 not sure ifs right tho
Step-by-step explanation:
C = 2<span>πr
C = 2 * 3.14 * 5.1
C = 32.028
You can round that to A. 32.03, because if the decimal after 2 is greater than it, then you round it to the number which is higher than it, which is 3. </span>
