Answer:
y=2 x=5
Step-by-step explanation:
3x-2y=11
2x-3y=4
you multiply both equations to cancel one variable out. in this case you multiply the first equation by 2 and the second by -3
6x-4y=22
+ -6x-9y=12
--------------------------
0x+5y=10
y=2
you plug that in either equation
3x-2(2)=11
3x-4=11
3x=15
x=5

my bad I realized mistake
Answer: although the question is incomplete, but from the details i got online, am able to give this answer.
A linear model is suitable. The regression relationship is thus ˆ
y= 0.511 + 0.159x where y = ridership and x = tourist numbers. Expected ridership if 10 million tourists visit is 2,101,000.The predicted ridership if there are no tourist at all is 511,000 though this prediction is out of sample and must be treated with caution as zero tourists is out of the data range used to form the model. The correlation coefficient is given by r=n∑XY-∑X∑Y/√[n∑X^2-(∑X)^2] [n∑Y^2-(∑Y)^2]
which equals 0.917 in this case. The R^2 = r^2 = 0.84.
Answer:
Option (2).
Step-by-step explanation:
Slope of a line passing through two points and is given by,
m =
From the graph attached,
Straight line given in the graph passes through two points (0, 0) and (2, 1).
Therefore, slope of the line given in the graph will be,
m =
=
Option (2). will be the answer.
