Answer:
C. More than one independent variable
Step-by-step explanation:
The difference between linear regression model and multiple regression model is that the linear regression has just one independent variable which is use to determine the dependent variable. While the multiple regression model has at least two or more independent variable which is use to determine the dependent variable.
every similar line means that they have the same value
x=8
y=10
go look for a way to find the last side in the small rectangle that has x and y
Answer:
The estimation for the proportion of tenth graders reading at or below the eighth grade level is given by:
And the 90% confidence interval would be given (0.131;0.169).
Step-by-step explanation:
We have the following info given:
represent the sampel size slected
number of students who read above the eighth grade level
The estimation for the proportion of tenth graders reading at or below the eighth grade level is given by:
The confidence interval for the proportion would be given by this formula
For the 90% confidence interval the significance is 
and 
, with that value we can find the quantile required for the interval in the normal standard distribution and we got.
And replacing into the confidence interval formula we got:
And the 90% confidence interval would be given (0.131;0.169).
Answer:
There would be $2,120
Step-by-step explanation:
First figure out what 3% of 2000 is which is 60. Multiply the 60 by 2 to get 120 then add 120 to 2000
Answer:
x=2, y=1. (2, 1).
Step-by-step explanation:
y=3x-5
6x+3y=15
-----------------
6x+3(3x-5)=15
6x+9x-15=15
15x-15=15
15x=15+15
15x=30
x=30/15
x=2
y=3(2)-5=6-5=1
