Answer:

pienso que el ejercicio no debería de regularse por nada si no por tu condición física ama lo que miras en el espejo diariamente pero promete a esa persona que se puede ver mejor. y cuando lo haces con amor a ti mismo y también a tu pareja por qué no te vas a sentir espectacular.

1. Write by hand, the formula for the counting rule of an experiment with k-steps with nk outcomes each. This is a process of ra
Verizon [17]

Answer:

         \large\boxed{\large\boxed{(n_k)^k}}

Explanation:

The formula for the counting rule of an experiment with k-steps with n_koutcomes each. This is a process of randomly selecting k numbers (or objects) with replacement (or repetition). Look for the formula in your notes, PowerPoint slides or textbook.

  • For the first step you have: n_k  posibble outcomes

  • For the second step you have:  n_k  posibble outcomes

  • For the third step you have:  n_k  posibble outcomes

  • For the k-step you have:  n_k  posibble outcomes

Thus,  a per the Fundamental Counting Principle or counting rule, the number of possible outcomes is:

           n_k\cdot n_k\cdot n_k\cdot ...\cdot n_k

That is n_k multiplied by itself k time, which is n_k raised to power k.

      (n_k)^k

Provide the missing reasons for the proof.
Marrrta [24]
1. given
2. corresponding parts theorem
- segments AB and DB are similar
and segments BC and BE are also similar. lastly the circle at angles C and E indicate that they are congruent
3. SSA similarly theorem
AB and BC are similar and BC and BE are similar and angle C and E are congruent. also the triangles are not congruent in length so that makes them similar.

i apologize if i am incorrect i like just learned this. have a great day and good luck on your studies
