Answer:
Solution of an Equation in Two Variables - Generally, a two-variable system solution is an ordered pair that makes BOTH equations valid.
Graph of an Equation in Two Variables - In the Ax + By = C form, linear equations with two variables will appear, and the resulting graph is always a straight line.
Linear Equation - Any equation that can be written in shape is a linear equation. Ax+b=0, 0.0 Where the real numbers are a and b, and x is a vector.
Linear Function - Those whose graph is a straight line are linear functions. The following form has a linear function. F(x) = y = a + bx.
I can't add a drawing right now, but I help these help!!
The answer is going to be 3,495
Answer:
a) sample of size n from the population has an equal chance of being selected.
b) Every member of the population has an equal chance of being included in the sample.
Step-by-step explanation:
Simple random sampling:
- It is a type of probabilistic sampling.
- It is an unbiased representation of population.
- The probability of selection is equal for every observation.
- A sample is taken in such a way that each member has an equal probability of being selected.
- A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.
- Thus,the correct interpretation is given by,
a) sample of size n from the population has an equal chance of being selected.
b) Every member of the population has an equal chance of being included in the sample.
- c) The simplest method of selection is used to create a representative sample.
The statement is false.
There is no pattern or technique used for selection. The selection is purely random.
- d) Each subset of the population has an equal chance of being included in the sample.
The statement is false.
Each object of the population has an equal chance of being included in the sample. and not each subset.
- e) Every sample of size n from the population has a proportionally weighted chance of being selected.
The given statement is false.

Step-by-step explanation:
Answer:
(a) The price for a revenue of $18,750 is $239.2.
(b) They sold 710 colonial houses and 2130 ranch houses
Step-by-step explanation:
(a) If the weekly revenue is defined as
then the price must be calculated as:
The roots of this function are
The first root is negative, so it is not a real solution. So the second root is the answer.
The price for a revenue of $18,750 is $239.2.
(b) Last year they sold three times as many ranch models (Hr) as they did colonial models (Hc):
The total amount of houses sold (colonial + ranch) is 2840
