Solve the equation.
Nutka1998 [239]

Answer:

C

Step-by-step explanation:

In this technique, if we have to factorise an expression like ax2+bx+c, we need to think of 2 numbers such that:

N1⋅N2=a⋅c=1⋅−12=−12

AND

N1+N2=b=−1

After trying out a few numbers we get N1=3 and N2=−4

3⋅−4=−12, and 3+(−4)=−1

x2−x−12=x2−4x+3x−12

x(x−4)+3(x−4)=0

(x+3)(x−4)=0

Now we equate the factors to zero.

x+3=0,x=−3

x−4=0,x=4

Statistics should not be used as a blind man does a lamp-post instead of illumination.
noname [10]

Answer:

Not quite sure what you are aiming for in this question; however, I guess that is true? A blind man wouldn´t simply rely on a lamp-post to get around.  I guess what is being said is that statistics should be used when it is useful? There are plenty of ways people can analyze that statement.
