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.

Find lim x->2 for f(x)=
TiliK225 [7]

LHL in not equal to RHL , Therefore the limit does not exists , Option D is the answer.(none)

<h3>What is the limit of a function ?</h3>

The limit of a function at a certain point is the value that the function approaches as the argument of the function approaches the same point.

It is given that

lim x->2 for f(x)

\lim_{x \rightarrow 2^-}f(x) = \lim_{x\rightarrow 2^+}f(x)

f(x) = 2x+1 x ≤2

f(x)= x² , x >2

When both the function tends to 2

Left Hand Limit

f(x) = 2 *2 +1

f(x) = 5

Right Hand Limit

f(x) = x² ,

f(x) = 4

LHL in not equal to RHL , Therefore the limit does not exists.

Which ratio forms a proportion with 7/14
Evgesh-ka [11]

Answer: 3/6

Step-by-step explanation:

Anytime you want to figure out the ratio, you divide the denominator (bottom number) by the numerator (top number).

First divide 14 by 7 and you get 1/2 (or 0.5 if you used the calculator). Now do this for each of the others until one matches or has the same ratio.

a) 5/12 : 12 ÷ 5= 2.4 * Not a match

b) 2/5: 5 ÷ 2= 2.5 * Not a match

c) 4/9: 9 ÷ 4= 2.25 * Not a match

d) 3/6: 6 ÷ 3 = 0.5 This is a MATCH!!!
