Answer:
The total change that will likely occur in 2 years is 
mg/L
Step-by-step explanation:
Given : The first year, they found the chloride concentration changed by 
mg/L .
It is estimated that the chloride concentration will change 
mg/L the next year.
To find : What is the total change that will likely occur in 2 years?
Solution :
The chloride concentration changed by 
mg/L in first year.
The chloride concentration will change 
mg/L the next year.
The total change that will likely occur in 2 years is
In a mixed fraction - mg/L
Add all the units together 8+11+6+8=45
then divide by the the number of units there are which is 5 so 45÷5 =9

Answer:
0.24315
Step-by-step explanation:
Using the z score formula to solve this question
z = (x - μ) / σ,
Such that:
x = raw score
μ = population mean
σ = population standard deviation.
From the question:
x = 3000
μ = 3550
σ = 870
z = (3000 - 3550) / 870
z = -550/870
z = -0.6962
Using the z score table as well as probability calculator(as requested in the question to find the z score)
The probability of having less than 3000 is obtained as:
P(x<3000) = 0.24315
