VARVARA [1.3K]

Answer:

$13,450

Step-by-step explanation:

The fixed costs of production, are the costs incurred that are independent from the production volume, that is, regardless of how many spinners the company produces, those costs will remain the same. If 'x' is the number of spinners produced, interpreting the cost function, we can see that it costs $1.28 to produce each spinner and that there is a cost that does not rely on production of $13,450. Therefore, the fixed cost of production is $13,450.

A drunk person is walking on the road. With probability 0.6 he takes a step forward and with probability 0.4 he takes a step bac
Molodets [167]

If a person after 10 steps is at his starting position, then this person takes 5 steps forward and 5 steps backward.

This is a binomial distribution with

  • probability to take step forward p=0.6;
  • probability to take step backward q=0.4;
  • n=10.

Then

Pr(\text{5 steps forward and 5 steps backward})=C_{10}^5p^5q^5=\\ \\=\dfrac{10!}{5!(10-5)!}\cdot (0.6)^5\cdot (0.4)^5=\dfrac{10!}{5!\cdot 5!}\cdot (0.6\cdot 0.4)^5=\\ \\=\dfrac{5!\cdot 6\cdot 7\cdot 8\cdot 9\cdot 10}{5!\cdot 2\cdot 3\cdot 4\cdot 5}\cdot (0.24)^5=7\cdot2\cdot 9\cdot 2\cdot (0.24)^5=252\cdot (0.24)^5=0.2006581248.

Answer: 252\cdot (0.24)^5=0.2006581248.
