After x days, the boy will have read 10x. If this is less than 192, we have ...

10x < 192

x < 192/10

x < 19.2

Graph the following piecewise function.

atroni [7]

Answer:

The graph of this piece-wise function is attached below.

Step-by-step explanation:

Given the function

${\displaystyle f(x)={\begin{cases}x^{2} +2&{\text{if }}-5\leq x$

A piece-wise function is a function which has multiple pieces.
Each of the pieces have their own restrictions.

The domain of a function is the set of input, or x, values for which the function is defined.
The range is the set of all values taken by the function

As the piece

$f(x)=x^{2} +2$ has the domain [-5, 3) and graph of this piece is attached below.

and

$f(x)=x-4$ has the domain [3, 7) and graph of this piece is attached below.

So, the domain of the piece-wise function can be composed as [-5, 3) U [3, 7) and range has the interval $\:\left[-1,\:27\right]$ .

i.e.

Domain: [-5, 3) U [3, 7)

Range: $\:\left[-1,\:27\right]$

The graph of this piece-wise function is attached below.

Keywords: piece-wise function, domain, range

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.
