3x+17=2x-6
-2x -2x * subtract 2x from both sides* *3x-2x is 1x*
1x+17=-6 *now subtract 17 from both sides*
-17 -17
1x=-23
1x. 1x
x=23
Answer:

Step-by-step explanation:

First, we need to make the demoninators the same so we times 4 by 5 and whatever we do to the bottom, we do to the top, and 5 by 4.



demoninator now doesn't change unless you're multiplying or dividing.

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.
Prism A 4x1x2=8
prism B 8x2x4=64
8/64 is the ratio, simplified would be 1/8
