Y=(x+1)(x-1) this is factored out
<span>Answer:
Multiple R is the correlation between y and y^
in a regression model. It is always non-negative, but has no nice interpretation as a proportion of variance, unlike its square. I can't think of too many uses for it and only know of one stat package that routinely reports it, SPSS.
Bivariate correlation only tells you about two variables at a time (though you can use partial correlation to remove other variables).</span>
Subtracting a value from the input x shifts the graph that number of units to the right.
The answer would be C.
I = 4500 × 0.05 × 3
<span>I = $ 675.00</span>
We have the expression:( x - 2 ) / ( x + 9 ) ( x - 5 )We have to find how many values of x must be excluded. The rule is : denominator must never equal zero. Anything divided by zero is undefined.x + 9 ≠ 0, x ≠ - 9x - 5 ≠ 0, x ≠ 5.Answer: Two values must be excluded, x = - 9 and x = 5.
