I. xy + 2y=3 Not linear equation because is grade 2 equation (xy).
II. x-2y = y Are linear equations in two unknowns (x and y).
III. 3x + 2y = 5 Are linear equations in two unknowns (x and y).

Answer: We are 95% confident that the mean income for all residents of this city is between $26700 and $35400.
Step-by-step explanation:
We know that a 95% confidence interval given an interval of values that we can be 95% sure , that it contains the true mean of the population, not 95% of data lies in it.
Given : A researcher is estimating the mean income of residents in a large city. The income variable is usually skewed to the right. She collects a random sample of 25 people.
The resulting 95% confidence interval is ($26700, $35400).
Then, valid conclusion will be : We are 95% confident that the mean income for all residents of this city is between $26700 and $35400.
Solution:
we have been asked to find a function for the given sitatution
The given situation is
A movie store sells DVDs for $11 each. what is the cost C of n DVDs.
Cost of 1 DVD is $11, then the cost of 2 DVDS will be 2x11=$22.
Cost of 1 DVD is $11, then the cost of 3 DVDS will be 3x11=$33.
......................................................................................................................
.......................................................................................................................
Cost of 1 DVD is $11, then the cost of n DVDS will be nx11=$11n.
Since the price is increasing exactly by $11 for each additional DVDS so the Graph will be discrete.
Hence the correct option is C=11n, Discrete.
