Answer:

The experiment is identifying whether a student gets less than a 75% on the entrance exam.

The trial is one exam being taken.

An outcome is a student scoring 80%.

Step-by-step explanation:

An experiment occurs when an intervention is made by a researcher and its effect are studied, thus the experiment here is identifying whether a student gets less than a 75% on the entrance exam.

The trial is the one exam being taken.

While an outcome is the aftermath of the experiment which includes a student scoring 80%.

Let U = {q, r, s, t, u, v, w, x, y, z} A = {q, s, u, w, y} B = {q, s, y, z} C = {v, w, x, y, z}. List the elements in the set: A
gtnhenbr [62]

Answer:

A \cup C=\left \{  \text{q, s, u, v, w, x, y, z} \right \}

Step-by-step explanation:

Given: \text{U}=\left \{\text{q, r, s, t, u, v, w, x, y, z} \right \}, \text{A}=\left \{\text{q, s, u, w, y} \right \}, \text{B}=\left \{\text{q, s, y, z} \right \},

\text{C}=\left \{\text{v, w, x, y, z} \right \}.

To find: The elements in the set A \cup C.

Solution:

We have,

\text{U}=\left \{\text{q, r, s, t, u, v, w, x, y, z} \right \}

\text{A}=\left \{\text{q, s, u, w, y} \right \}

\text{B}=\left \{\text{q, s, y, z} \right \}

\text{C}=\left \{\text{v, w, x, y, z} \right \}

Now, A \cup C will contain all the elements in the set A and all the elements in set C.

So, A \cup C=\left \{  \text{q, s, u, v, w, x, y, z} \right \}.

Hence, A \cup C=\left \{  \text{q, s, u, v, w, x, y, z} \right \}.

Given: F(x) = 5x - 6 and G(x) = x - 4
fomenos

Answer:

Correct choice is \dfrac{x+26}{5}

Step-by-step explanation:

1. If F(x)=5x-6, then you can find the inverse F^{-1}(x):

y=5x-6,\\ \\5x=y+6,\\ \\x=\dfrac{y+6}{5},\\ \\F^{-1}(x)=\dfrac{x+6}{5}.

2. If G(x)=x-4, then

y=x-4,\\ \\x=y+4,\\ \\G^{-1}(x)=x+4.

3. Hence,

G^{-1}(F^{-1}(x))=G^{-1}\left(\dfrac{x+6}{5}\right)=\dfrac{x+6}{5}+4=\dfrac{x+26}{5}.
