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.
