Answer:
Campsites be chosen in 680 ways.
Step-by-step explanation:
Given:
Number of campsites= 17
Number of campsites that are to be occupied=3
To Find:
Number of ways can the campsites be chosen=?
Solution:
Combination:
In mathematics, a combination is a way of selecting items from a collection where the order of selection does not matter. Suppose we have a set of three numbers P, Q and R. Then in how many ways we can select two numbers from each set, is defined by combination.
nCr = n(n - 1)(n - 2) ... (n - r + 1)/r! = n! / r!(n - r)!
No of ways in which campsites can be chosen=

Answer: 
<u>Step-by-step explanation:</u>
There are 130 students.
There are 58 boys --> 72 girls
A) 49 chose football: 27 are girls --> 22 are boys
B) 72 girls: 24 chose running, 27 chose football --> 21 girls chose tennis
C) 27 students chose tennis: 21 are girls --> 6 are boys.
D) 58 boys: 22 chose football, 6 chose tennis --> 30 boys chose running.
Total running = 30 boys + 24 girls = 54
Total students = 130
Answer: Inductive Reasoning.
Had to complete the question first.
Maria is writing a list of numbers. She asked Susanne what the next number would be . After looking at the list: 7,14,21,28,35,42,_Susanne states,”the next number will be 49” inductive or deductive.
Step-by-step explanation:
inductive reasoning: This is known as a process of using observations and examples to reach a conclusion or decision.
When ever a pattern or trend is used to predict the next possible outcome, you are using inductive reasoning. Just like from Maria list Susanne was able to predict that the next number would be 49 because the sequence increases with an interval of 7. ( 7, 14, 21, 28, 35, 42, 49).
