Answer:
A. R2 = 0.6724, meaning 67.24% of the total variation in test scores can be explained by the least‑squares regression line.
Step-by-step explanation:
John is predicting test scores of students on the basis of their home work averages and he get the following regression equation
y=0.2 x +82.
Here, dependent variable y is the test scores and independent variable x is home averages because test scores are predicted on the basis of home work averages.
The coefficient of determination R² indicates the explained variability of dependent variable due to its linear relationship with independent variable.
We are given that correlation coefficient r= 0.82.
coefficient of determination R²=0.82²=0.6724 or 67.24%.
Thus, we can say that 67.24% of total variability in test scores is explained by its linear relationship with homework averages.
Also, we can say that, R2 = 0.6724, meaning 67.24% of the total variation in test scores can be explained by the least‑squares regression line.
Answer:
it would be about 5984 times around the earth
Step-by-step explanation:
first of all 149,000,000 miles is active lifetime
Using those measurements, the equatorial circumference of Earth is about 24,901 miles
so therefore if you divide 149,000,000 by 24,901 you would get the answer of 5983.69543392 so if you round all the numbers to the nearest whole number you would get 5984
hope tis helps out with your question
The perimeter would be ≈ 36.797836892947.
Rounded would be about 37, or 36.8.
Hope this helps!!!!
Solving for P:
≈36.79784
Hope this helps!!
