Let's solve your equation step-by-step.
6+2s−8s=18
Step 1: Simplify both sides of the equation.
6+2s−8s=18
6+2s+−8s=18
(2s+−8s)+(6)=18(Combine Like Terms)
−6s+6=18
−6s+6=18
Step 2: Subtract 6 from both sides.
−6s+6−6=18−6
−6s=12
Step 3: Divide both sides by -6.
−6s/−6
=12/−6
s=−2
Answer:
s=−2
Answer:
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
Where and
And for this case we select a sample size of n= 81. Since the distribution for X is normal then we know that the distribution for the sample mean is given by:
And the standard error of the mean would be:
4.1.5
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Answer:
Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept. plz mark brainliest
