Answer:
x ≥ 9/2
Step-by-step explanation:
5x - 2 ≥ 3x + 7
2x ≥ 9
x ≥ 9/2
Answer:
The equation for regression line and predicting a husband's height for married couples in their early 20s
Equation: Y'=33.67+0.54*X'
Step-by-step explanation:
r=0.5
x'=64.5
Sx=2.5
y'=68.5
Sy=2.7
General regression line equation is:
Y'=a+b*X'
so the slope of the regression line is the linear correlation coefficient multiplied by the standard deviation for y' divided by the standard deviation for x'

The intercept with axis y is the mean of the decreased by the product of the slope and the mean of x

The equation regression line then is:
Y'=33.67+0.54*X'
9 because if you subtract 11 from 19 you het 9
Answer:
4/-2
Step-by-step explanation:
Start at a point where the line intersects a firm coordinate like y=2 then use rise/run rise is vertical and run is horizontal count from the intersection up to where the line intersects another firm point in this case y=6 then count the run which lands on x=-2 y=6 which gives you the slope of 4/-2
Answer:
12,040,000
Step-by-step explanation:
You would first do 8.6 million times 0.10 and then you would multiply that times 4 bc of 4 years that passed and finally add to 8.6 million!
