Answer:
The standard error of the sulfate in a collection of 10 water samples is of 0.506 mg/L.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard error .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Standard deviation of 1.60 mg/L.
This means that
Collection of 10 samples:
This means that
The standard error of the sulfate in a collection of 10 water samples is of 0.506 mg/L.
I am not positive but I think it is 2.617. I hope that helps
The system of inequalities with no solution is x > 3 x < 1
<h3>How to determine the system with no solutions? </h3>
The systems of inequalities are given as:
x < 3 x < 1
x > 3 x > 1
x < 3 x > 1
x > 3 x < 1
As a general rule, it is impossible for a variable to be greater than a higher number and less than a smaller number.
This means that if x is greater than 3, then it must be greater than 1
Hence, the system of inequalities with no solution is x > 3 x < 1

Answer:
5.5
Step-by-step explanation:
Miranda mixes 34.5 fluid ounces of blue paint
40.5 fluid ounces of red paint.
2 fluid ounces of black paint to produce a purple paint
She pours this purple paint into 14 jars
Therefore the amount of paint in each jar can be calculated as follows
= 34.5 + 40.5 + 2
= 77/14
= 5.5 fluid ounces
Hence there are 5.5 fluid ounces of purple paint in each jar
