What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The rugby squad from Bimini High School won the state title that year. A record of their wins and losses is shown, in which the relationship between wins and losses is sorted by the number of points scored. From observation, The best evidence is given when scoring 40 points or more in a game, the Bimini team won more games (18/20) than when scoring fewer than 40 points (11/20).

Thus, the best evidence is given when scoring 40 points or more in a game, the Bimini team won more games (18/20) than when scoring fewer than 40 points (11/20).

What is the permutation and combination?

Permutation and Combination form the principles of counting and they are applied in various situations.

A permutation is a count of the different arrangements which can be made from the given set of things. In permutation the details matter, as the order or sequence is important.

Here given that,

A blood bank needs 5 people to help with a blood drive. 18 people have volunteered.

So,

^nC_r=(n!)/(r(n-r)!)

Here n=18, r=5

Then

^(18)C_5=(18!)/(5(18-5)!)\n\n^(18)C_5=(18!)/(5(13)!)\n\n^(18)C_5=((18)(17)(16)(15)(14)(13))/(5(13))\n\n^(18)C_5=((18)(17)(16)(15)(14))/(5)\n\n^(18)C_5={(18)(17)(16)(3)(14)}\n\n^(18)C_5=205632

Hence, the different groups of 5 can be formed from the 18volunteers is

^(18)C_5=205632.

Step-by-step explanation:

How many nickles and dimes are $5.20 if there are six times more nickles than dimes?

Answers

In looking for the number of nickel and dimes we need to establish first equations:
n = $0.05
d = $0.1

0.05n + 0.1d = 5.20
0.05n = 6 (0.1d) ; n = 0.083d

Then we will solve it by substitution:
0.05(0.083d) + 0.1d = 5.20
0.42d + 0.1d = 5.20
0.52d = 5.20
d = 10

n = 0.083(10)
n = 0.83
