**Answer:**

4,2

**Step-by-step explanation:**

your correct answer should be: z = (x - mean) / SD = (79 - 70) / 3 = 3

P (Z > 3)? = 1 - F (z) = 1 - F (3) = 0.00135 i hope this is helpful! :D

There are 5005 **different groups**

<h3>How to determine the number of groups?</h3>

The given parameters are:

Players, n = 15

Selected, r = 6

The **number of groups** is then calculated as:

This gives

Apply the **combination formula**

Evaluate the expression

Group = 5005

Hence, there are 5005 **different groups**

We have been given a graph. We are asked to find the values of x,y and z.

We will use parallel line's angles to solve our given problem.

We know that corresponding angles of parallel lines are equal.

We can see that angle and 67 are corresponding angles, so we can set an equation as:

**Therefore, the value of x is 32.**

We know that interior angles on same side of transversal are supplementary.

We can see that and 67 are interior angles, so we can set an equation as:

**Therefore, the value of y is ****.**

We can set an equation for angle z as:

Upon substituting value of z, we will get:

**Therefore, the value of z is 13.5.**
