1. x=−y+8−z
2.x=−7−4y−5z (everything over 4)
3.x=2−z
1.y=-x+8-z
1.z=-x+4-y
2.y=7+4x-5x (everything over 4)
2.z=7+4x-4y (everything over 5)
3.z=2-x
Answer:
-15 meters
Step-by-step explanation:
The tunnel of fear starts at 0 meters, goes up to 50 meters, then drops 65 meters. This expressed as an equation is:
(0+50)-65=x
50-65=x
-15=x
Answer:

Step-by-step explanation:
Data given
n=20 represent the sampel size
represent the sample mean for the independent variable (IQ score of the husband)
represent the sample mean for the dependent variable.
r =0.925 represent the correlation coefficient
Solution to the problem
The general expression for a linear model is given by:

Where
is the intercept and
the slope
For this case we have a linear model given by the following expression:

Where -3.34 is the intercept and 1.07 the slope. In order to find the best predicted value when X = 91 we just need to replace into the equation the value of 91 and we got this:

On this case is the best predicted value because
we have an unbiased estimator.
Well it would make sense that Jenny had 6 marshmallows and Julie did not put any in, Hope this helped a little
