A chain has 47 links. 13 link from one end is rusted. From the other end 17 link is also rusted. How many links lie between thes
2 answers:
Answer:
17 links
Step-by-step explanation:
<em>1. </em>13 Links and 17 links are rusted. Since we need to find out the number of links that are not rusted, we need to add 13+17.
<em>a.</em><em> 13 + 17 = 30</em>
2. Now since we added the number of lines rusted, we now should subtract the ones rusted and the one not rusted to get the answer.
a. 47-30 = 17

<h3>What are permutation and combination?</h3>A permutation is an act of putting things or elements in the right sequence. Combinations are a method of picking things or pieces from a collection of objects or sets when the sequence of the objects is irrelevant.
You and your mom enter the drawing with three different prices the prizes are awarded at random is a total of 8 people entered the drawing.
Then the number of the ways in which you can win first prize and your mom went the second prize will be
Let x be the number of different ways.
Then we have
Thus, the number of ways in which you can win first prize and your mom went the second prize will be 8.

Part 1:
Given that a<span> store had 235 MP3 players in the month of January and that every month, 30% of the MP3 players were sold and 50 new MP3 players were stocked in the store.
</span>The number of MP3 players in the store after the previous months sale is given by 0.7f(n - 1) and <span>the number of MP3 players in the store after new MP3 were added is 0.7f(n - 1) + 50.
Therefore, the </span><span>recursive function that best represents the number of MP3 players in the store f(n) after n months is given by </span><span>f(n) = 0.7 x f(n − 1) + 50, f(0) = 235, n > 0
Part 2:
The average rate of change of a function from a to b is given by
