Answer:
58.6% of the variation in length (in cm) of new born boys and their weight (in kg) is explained by the line of best fit.
Step-by-step explanation:
Given the following :
R² value = 58.6% comparing the length (cm) of new born boys to their weight (kg)
The R² value is called the Coefficient of determination. It is obtained by taking the square of the correlation Coefficient (R). The value gives the proportion of Variation between the independent and dependent variables which is explained by regression line. In the scenario above, the R² value means that 58.6% of the variation in length in centimeter of new born boys and their weight (in kg) is explained by the line of best fit. While (100% - 58.6% = 41.4%) is due to other factors.
Answer:
8 yd
Step-by-step explanation:
The opposite side is 14 and the lower portion plus the missing value would equal 14:
14 = 6 + ?
So subtract 6 from 14 to get the missing length, 8.
All the points if they lay on top of eachother
if they arent on top of eachother, they can intersect at 2 points
Answer:
<em>The slope of the line is -1</em>
Step-by-step explanation:
<u>Slope of a Line</u>
Suppose we know a given line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated as follows:
From the table in the image, we select the points (1,4) (3,2). The slope is:
Now select two other points like (5,0) (7,-2)
Following the same procedure with any other pair of points, we'll get the very same result:
The slope of the line is -1
Answer:
z=4/3
z=-1/3
Step-by-step explanation:
|6z-3|=5
1. 6z-3=5 6z=8 z=4/3
2. 6z-3=-5 6z=-2 z=-1/3
