Answer:
y=(-4/3)x
Step-by-step explanation:
you put the points into this equation to find the slope
(y2-y1)/(x2-x1)
now lets label the points
(6,-8)
x1=6 and y1=-8
(3,-4)
x2=3 and y2=-4
Input into equation
(-4-(-8))/(3-6)=
(-4+8)/(3-6)
4/-3
Nine plus a unknown number equals unknown.
Answer:
<ABC
Step-by-step explanation:
When you use three points, two points must be on the rays of the anlge. The middle point must be the vertex.
Answer: <ABC
Answer:
a. For n=25, the mean and standard deviation of the prices of the mobile homes all possible sample mean prices are $63,800 and $1,580, respectively.
b. For n=50, the mean and standard deviation of the prices of the mobile homes all possible sample mean prices are $63,800 and $1,117, respectively.
Step-by-step explanation:
In this case, for each sample size, we have a sampling distribution (a distribution for the population of sample means), with the following parameters:

For n=25 we have:

The spread of the sampling distribution is always smaller than the population spread of the individuals. The spread is smaller as the sample size increase.
This has the implication that is expected to have more precision in the estimation of the population mean when we use bigger samples than smaller ones.
If n=50, we have:
