At a DBE lecture of 100 students, there are 29 women and 23 men. Out of these students, 4 are teachers and 24 are either men or
den301095 [7]

Answer:

The number of women teachers attending the lecture is 1.

Step-by-step explanation:

Denote the variables as follows:

<em>M</em> = men

<em>W</em> = women

<em>T</em> = teacher

The data provided is:

n (M) = 23

n (W) = 29

n (T) = 4

n (M ∪ T) =  24

Compute the number of men teachers as follows:

n(M\cap T)=n(M)+n(T)-n(M\cup T)

               =23+4-24\\=3

Compute the number of women teachers as follows:

        n(T)=n(M\cap T)+n(W\cap T)

             4=3+n(W\cap T)

n(W\cap T)=1

Thus, the number of women teachers attending the lecture is 1.

Graph the function and identify all key characteristics f(x)=x^3-12x^2+45x-54
damaskus [11]

Answer:

We kindly ask you to see the explanation and the image attached below for further details.

Step-by-step explanation:

From Function Theory we know that third order polynomials are continuous functions with one relative minimum and one relative maximum and whose domain and range comprehends the set of all real numbers. Since the leading coefficient of the polynomial is positive, then two increasing intervals and only one increasing interval exist.

Now we proceed to graph the function and label each relevant information when possible.

Domain

Dom \{f(x)\} = \mathbb{R}

Range

Ran \{f(x)\} = \mathbb{R}

Zeros

x = 3 and x = 6
