Answer: x = 0.3
Step-by-step explanation:
12x-18=-15+6x
6x = 3
x = 1/2 or 0.5

<h2>
Answer: 20°</h2>
<h3>
Step-by-step explanation:</h3>
Supplementary angles sum up to 180 °
Complementary angles sum up to 90°.
The supplement of 110° = 180° - 110° = 70°
The complement of 70° = 90° - 70° = 20°
<u>Simplier version:</u>
The complement of the supplement of 110° = (90° - (180° - 110°))
= 20°
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.
