Vinvika [58]

Answer:

You can distribute the cookies and candies in four ways.

Step-by-step explanation:

Since cookies and candies are indistinguishable, we can use a combination. In this case represents the number of possible ways to distribute (without repetition) the cookies and candies (p) among a given number of children (n):

$\begin{pmatrix}n\\ p\end{pmatrix}=\frac{n!}{p!(n-p)!}\\\begin{pmatrix}4\\ 3\end{pmatrix}=\frac{4!}{3!(4-3)!}=\frac{4!}{3!1!}=4$

What is z equal to ? Please help

MakcuM [25]

The sum of the interior angles of a triangle (half the rhombus in this case) is 180. Because of the properties of a rhombus, z and x will be equal to each other. Therefore, $124 + z + z = 180$ .
$124 + z + z = 180$
$124 + 2z = 180$
$2z = 56$
$z = 28$
Thus, z is equal to 28.
