Answer:
2291.3
Step-by-step explanation:
The given regression equation is
y=9.82 x + 671
Where y= Hiker's elevation in feet and x= number of minutes.
Here, number of minutes is an independent variable while Hiker's elevation in feet is the dependent variable. The slope coefficient 9.82 depicts that due to unit increase in number of minutes the Hiker's elevation in feet increases by 9.82 feet.
We have to estimate the hiker's elevation after 165 minutes using the above regression equation. We simply put x=165 to estimate the hiker's elevation.
y= 9.82(165) + 671
y= 1620.3+671
y= 2291.3
So, the estimated hiker's elevation after 165 minutes is 2291.3 feet.
If a line segment is partitioned having ending points (1,4),(7,1) in the ratio of 3:1 then the coordinates will be (25/4,7/4)
Given Ending points (1,4), (7,1) and the ratio 3:1 in which the line segment is divided.
If we are given the ratio m:n and the ending points of the line segment then the coordinates of the point dividing the segment will be (mx2+nx1/m+n,my2+ny1/m+n)
Putting the values of m=3 n=1 x1=1 y1=4 x2=7 and y2=1 we get
Coordinates (x,y)=(3*7+1*1/3+1,3*1+1*4/3+1)
=(21+1/4,3+4/4)
=(22/4,7/4)
Hence the point which is dividing the line segment having ending points (1,4) and (7,1) in the ratio 3:4 is (22/4,7/4).

Answer:
(- 4, 9 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 24 → (1)
3x + 2y = 6 → (2)
Subtract (2) from (1) term by term to eliminate x
3x - 3x + (4y - 2y) = 24 - 6
2y = 18 ( divide both sides by 2 )
y = 9
Substitute y = 9 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(9) = 24
3x + 36 = 24 ( subtract 36 from both sides )
3x = - 12 ( divide both sides by 3 )
x = - 4
solution is (- 4, 9 )
