Answer:
5.47% of the total variation between the two variables can be explained by the regression line.
Step-by-step explanation:
Given :
R value = 0.234
The R value is the correlation Coefficient ; which gives the type and level of correlation between two variables.
However, to Obtian the percentage variation which can be explained by by the regression line, we have to obtain the Coefficient of determination, R².
R² value is Obtained by taking the squared of the correlation Coefficient
Hence,
R² = 0.234² = 0.054756
R² = 0.05476 * 100% = 5.4756%
Hence, R² = 5.48%
This is interpreted as ; 5.47% of the total variation between the two variables can be explained by the regression line.
Answer:
45 in, 30 in and 25 in
Step-by-step explanation:
Add the parts of the ratio : 9 + 6 + 5 = 20 parts
Divide the perimeter by 20 to find one part of the ratio.
= 5 ← 1 part of the ratio
9 parts = 9 × 5 = 45
6 parts = 6 × 5 = 30
5 parts = 5 × 5 = 25
45 inches, 30 inches and 25 inches are the measures of each side
Answer:
The distance is 
or 
.
Step-by-step explanation:
Slope of parallel: 2
Slope of perpendicular: -1/2
Pick a point for y =2x + 7. For example (0,7)
Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).
Distance formula 
Insert (0,7) and (4,5)
= 
1.2625 i dunno if this is correct though on my calculations
Step-by-step explanation:
If it looks like this: < with a line under it then it's called a less than or equal to sign.
If it looks like this: > with a line under it then it's a greater than or equal to sign
