Answer:
178
1900 = 5(x+202)
Step-by-step explanation:
Sasha= 5 times Bess and Jeremy
1900 = 5 (202 + X)
/5 /5
380 = 202 + x
-202 -202
178 = x
Answer:
The dependent variable is the final grade in the course and is the vriable of interest on this case.
H0: ![\beta_1 = 0](https://tex.z-dn.net/?f=%5Cbeta_1%20%3D%200)
H1: ![\beta_1 \neq 0](https://tex.z-dn.net/?f=%5Cbeta_1%20%5Cneq%200)
And if we reject the null hypothesis we can conclude that we have a significant relationship between the two variables analyzed.
Step-by-step explanation:
On this case w ehave the following linear model:
![Y= 21.839 +0.724 X](https://tex.z-dn.net/?f=Y%3D%2021.839%20%2B0.724%20X)
Where Y represent the final grade in the course and X the student's homework average. For this linear model the slope is given by
and the intercept is ![\beta_0 = 21.839](https://tex.z-dn.net/?f=%5Cbeta_0%20%3D%2021.839)
Which is the dependent variable, and why?
The dependent variable is the final grade in the course and is the vriable of interest on this case.
Based on the material taught in this course, which of the following is the most appropriate alternative hypothesis to use for resolving this question?
Since we conduct a regression the hypothesis of interest are:
H0: ![\beta_1 = 0](https://tex.z-dn.net/?f=%5Cbeta_1%20%3D%200)
H1: ![\beta_1 \neq 0](https://tex.z-dn.net/?f=%5Cbeta_1%20%5Cneq%200)
And if we reject the null hypothesis we can conclude that we have a significant relationship between the two variables analyzed.
Answer:
-2x = -60
Isolate x and simplify.
2x = 60
x = 30
Straight vertical line through x=30.
I’m so confused?? what’s the question?
Temperature after 20 minutes is found by multiplying-2.5 by 20 since it goes down by 2.5 degrees for one minute. -2.5 * 20 = -50. Adding this to 180.3 will give the temperature 130.3 degrees.
