\bf A=\cfrac{1}{2}20h\implies A=\cfrac{20h}{2}\implies A=10h

now, the range for that equation is all real numbers, is a linear equation and therefore will pass the "vertical line test" and thus be a one-to-one function, and therefore will have an inverse function.

for a function that has an inverse function, the range of the original function is exactly the same as the domain for its inverse.  Therefore, if the range of that function is all real numbers, then the domain of its inverse is just that.

what's the inverse, well, let's do the switcharoo.

\bf A=10h\qquad inverse\implies \boxed{h}=10\boxed{A}\impliedby A^{-1}(h)

we are not solving for "h", because, well, is already solved for "h".

Answer:

  (b)  (-3, -1)

Step-by-step explanation:

Differences between adjacent f(x) values are ...

  -31, -13, -1, +5, +5, -1, -13

The function is increasing on intervals where the differences are positive: between (-3, -11) and (-1, -1). That is ...

  f(x) is increasing on (-3, -1)

The probability that a randomly selected elementary or secondary school teacher from a city is a female is , holds a second job
julsineya [31]

Answer:

The probability that an elementary or secondary school teacher selected at random from this city is a female or holds a second job is 0.90.

Step-by-step explanation:

Denote the events as follows:

<em>X</em> = an elementary or secondary school teacher from a city is a female

<em>Y</em> = an elementary or secondary school teacher holds a second job

The information provided is:

P (X) = 0.66

P (Y) = 0.46

P (X ∩ Y) = 0.22

The addition rule of probability is:

P(A\cup B)=P(A)+P(B)-P(A\cap B)

Use this formula to compute the probability that an elementary or secondary school teacher selected at random from this city is a female or holds a second job as follows:

P(X\cup Y)=P(X)+P(Y)-P(X\cap Y)\\=0.46+0.66-0.22\\=0.90

Thus, the probability that an elementary or secondary school teacher selected at random from this city is a female or holds a second job is 0.90.
