Answer:
A
Step-by-step explanation:
Compare the images to 90°, which is right angle, and forms an L. A is just past 90°, B is past 270°, and C is less than 90°.
Answer:
A
Step-by-step explanation:
If we take each small section to be "1" unit, we can say the large sections (for "2" and "5") are "2" units each. So in total there will be 8 sections.
Since 5 is "2" sections, we can say:
P(5) = 2/8 = 1/4
And 6 is "1" section, so we can say:
P(6) = 1/8
Definitely, Probability of landing a 6 is HALF that of probability of landing a 5. Also we can see this is the picture.
So, from the answer choices, A is right.
Answer:
Regression Line is given by,
y = 22.909 + 0.209 x
The course grade of a student in the course who spent an average of 103 minutes in the course each week is: 22.909 + 0.209 × 103 = 44.436
Step-by-step explanation:
The equation of Regression equation is of the form of:
y = a + bx
where, a is intercept and b is slope
The formula for a and b is given by,
![a=\frac{\sum Y \sum X^2-\sum X \sum XY}{n\sum X^2-(\sum X)^2}\\ and, b = \frac{n\sum XY -\sum X \sum Y}{n\sum X^2-(\sum X)^2}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B%5Csum%20Y%20%5Csum%20X%5E2-%5Csum%20X%20%5Csum%20XY%7D%7Bn%5Csum%20X%5E2-%28%5Csum%20X%29%5E2%7D%5C%5C%20and%2C%20b%20%3D%20%5Cfrac%7Bn%5Csum%20XY%20-%5Csum%20X%20%5Csum%20Y%7D%7Bn%5Csum%20X%5E2-%28%5Csum%20X%29%5E2%7D)
Here, ∑X = 1149.8, ∑Y = 377.2, ∑XY = 93115.95, ∑X² = 320246.72
Thus, a = 22.909
and b = 0.209
Thus, Regression Line is given by,
y = 22.909 + 0.209 x
Thus, The course grade of a student in the course who spent an average of 103 minutes in the course each week is: 22.909 + 0.209 × 103 = 44.436
Now plotting these line:
