The answer is 200 :)))))))
Answer:
The measure of angle 4 is 48 degrees.
Step-by-step explanation:
When two angles <u>forming an X</u>
- shape share a common vertex and
- oppose each other
the angle has the same value.
We call this type of angles opposing angles or vertical angles.
<h2>Answer:
</h2>
The length of VW is 23°
<h2>Step-by-step explanation:
</h2><h3>Known :
</h3>
<h3>Asked :
</h3>
VW = ?
<h3>Solution :
</h3>
Since the UV line and UX line has the same length, so the VW line should have the same length as the WX line.
VW = WX
23 = 23
<h3>Conclusion :
</h3>
The length of VW is 23°
Differentiating both sides of
with respect to 
yields
At the point (3, 4) (so 
and 
), the tangent line has slope
Then the tangent line to (3, 4) has equation
This question is incomplete, the complete question is;
Suppose John is a high school statistics teacher who believes that watching many hours of TV leads to lower test scores. Immediately after giving the most recent test, he surveyed each of the 24 students in his class and asked them how many hours of TV they watched that week. He then matched each student's test grade with his or her survey response. After compiling the data, he used hours of TV watched to predict each student's test score. He found the least-squares regression line to be y" = -1.5x + 85.
He also calculated that the value of r, the correlation, was -0.61.
what is the correct value of the coefficient of determination R² and give a correct interpretation of its meaning
Answer:
Interpretation of coefficient of determination R² = 0.3721
R² = 0.3721, meaning 37.21% of the total variation in test scores can be explained by the least square regression line
Step-by-step explanation:
Given the data in the question;
the least square regression line is;
y" = -1.5x + 85
the correlation coefficient r = -0.61
Now, the coefficient of determination R² is square of correlation coefficient r
R² = -61²
R² = 0.3721
