Step-by-step explanation:
Sampling
This is a common statistics practice, when we want to study something from a population, we find a sample of this population.
For example:
I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents wheter they are Buffalo Bills fans, and expand this to the entire population of New York State residents.
The population of interest are all residents of New York State.
A simple random sample of 500 students was selected from all the students enrolled in statistics classes.
This means that the population of interest for this student is the students whom are enrolled in statistics classes.

Step-by-step explanation:
Answer:
I would say that they are different because if x - a has a value to the equation then that means a - x will not have the same value because it may be rearranged to a different equation but that doesn't mean that they will have the same value. that explain why x - a and a - x are not the same
W=-3m+205
m=number of months
205= weight at first to start the diet
w=weight
a)
m=0
so;
w=-3(0)+205=205
Answer: Chris weight at the start of the diet 205 pounds
b)
W=-3m+205
The weight lost each month is the number beside "m", in this case is -3 pounds
Answer: Chris lose 3 pounds per month
c)
w=205-45=160
so
160=-3m+205
-3m+205=160
-3m=160-205
-3m=-45
m=-45/-3=15
Answer: 15 months.
Answer:
x = 4
y = -2
Step-by-step explanation:
x + 10y = -16
-x -4y = 4 <-- ( multiplied x+4y=-4 with -1 so the x's cancel)
6y = -12
y = -2
put -2 back in the equation to get x
x + 10y = -16
x -20 = -16
x = 4
