Answer:No. A strong correlation does not imply causation.
Step-by-step explanation:
Cause and effect relationship is not explained by correlations. A cause and effect relationship can only be established by carrying out carefully controlled experiments.
Hence, a strong correlation between the the intake of soda and accidents does not necessarily imply that soda intake causes accident.
A lurking variable in this study may be the speed of the drivers. A lurking variable is not controlled but significantly impacts results obtained from the study.
Since the speed of the drivers is not strictly controlled, it may just be a lurking variable.
Answer:
10/√2
To rationalize multiply the numerator and denominator by the surd in the denominator
10/√2×√2/√2
=10√2/2
Answer:
o,5,10
Step-by-step explanation:
Here is how to solve it:
1) isolate x for x+y=2:
x=2-y
2)now plug this value in 3x^2-y^2=1
3(2-y)^2-y^2=1
simplify to get 2y^2-12y+11=0
and you get:
3)plug these(y1,y2) values in x+y=2
and you get:<span>

Answer:
Step-by-step explanation:
The first step you want to do is get one variable by itself. We are going to start by isolating y by itself.
-3x + 9y = -27
9y = 3x - 27
y = 1/3x - 3
By isolating y by itself, you now have a function written in slope-intercept form. To graph this function, you can draw a point at (0,-3), then use rise/run to go up 1 unit and over 3 units to the next point (3,-2). You can then draw a line based on this information.
