Answer:
3/4 or 6/8
Step-by-step explanation:
the thumbtack goes to 12/16 on the ruler which can be simplified to 3/4 or 6/8.
Answer:
its either A/B
Step-by-step explanation:
Answer:
the answer shoudl be OB 4
Step-by-step explanation:
(y+7)/(-9+7) = (x+10)/(-5+10)
(y+7)/(-2) = (x+10)/5
5(y+7)=-2(x+10)
5y+35= -2x-20
the equation :
5y=-2x-20-35
devided by 5
=> y = -2/5 x - 11
or y = -0.4x - 11
Answers in bold:
- Regression equation: y = 1.2x - 21.3
- Final Answer: 33
=======================================================
Explanation:
I'm not sure how your calculator works, but I'm assuming you can copy/paste the given numbers into the calculator somehow to have it determine the regression equation.
The tool I used is GeoGebra and the regression equation it produced was
y = 1.2x - 21.3
Each decimal value is approximate and rounded to the nearest tenth.
---------------------------
Once we determine the regression line, plug the homework grade x = 45 to find the associated test grade (y). This is a predicted test grade.
y = 1.2x - 21.3
y = 1.2*45 - 21.3
y = 32.7
y = 33
If a student got a 45 on a homework, then we predict their test grade should be around 33.
