an nhl hockey season has 41 home games and 41 away games. show by contradiction that at least 6 of the home games must happen on the same day of the week.

Answers

Answer 1

By contradiction, we will prove that at least 6 of the home games in an NHL hockey season must happen on the same day of the week.

To show by contradiction that at least 6 of the home games must happen on the same day of the week, let's assume the opposite - that each home game happens on a different day of the week.


This means that there are 7 days of the week, and each home game happens on a different day. Therefore, after the first 7 home games, each day of the week has been used once.


For the next home game, there are 6 remaining days of the week to choose from. But since we assumed that each home game happens on a different day of the week, we cannot choose the day of the week that was already used for the first home game.



Thus, we have 6 remaining days to choose from for the second home game. For the third home game, we can't choose the day of the week that was used for the first or second home game, so we have 5 remaining days to choose from.



Continuing in this way, we see that for the 8th home game, we only have 2 remaining days of the week to choose from, and for the 9th home game, there is only 1 remaining day of the week that hasn't been used yet.



This means that by the 9th home game, we will have used up all 7 days of the week. But we still have 32 more home games to play! This is a contradiction, since we assumed that each home game happens on a different day of the week.


Therefore, our assumption must be false, and there must be at least 6 home games that happen on the same day of the week.

Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer.1 inch ≈ 1.578 × 10 -5 miles.

Answers

Answer: The number of inches in 1225 miles is [tex]7.763\times 10^7[/tex]

Step-by-step explanation:

Scientific notation is defined as the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

Example: 3000 is written as [tex]3.0\times 10^3[/tex]

Given : [tex]1.578\times 10^{-5}[/tex] miles = 1 inch

Thus 1 mile = [tex]\frac{1}{1.578\times 10^{-5}}=0.634\times 10^5[/tex] inches

1225 miles = [tex]\frac{0.634\times 10^5}{1}\times 1225=776.3\times 10^{5}=7.763\times 10^7[/tex] inches

Answers

Mary should make sure to choose a bank that is FDIC insured. Furthermore, if she has more than maximum deposit insurance amount to deposit, she should spread her deposits out among several separate banks. These should be totally different banks, not simply different branches of the same bank. The FDIC will insure up to the maximum deposit insurance amount at each bank, even if the bank fails.

Answers

Given:

The decimal number is 15.265.

To find:

The decimals in the form of [tex]\dfrac{p}{q}[/tex] and p,q are co-primes.

Solution:

Let the decimal number be [tex]x=15.265[/tex].

It can be rewritten as

[tex]x=15.265\times \dfrac{1000}{1000}[/tex]

[tex]x=\dfrac{15265}{1000}[/tex]

[tex]x=\dfrac{5\times 3053}{5\times 200}[/tex]

Cancel out the common factors.

[tex]x=\dfrac{3053}{200}[/tex]

Here, p=3053 and q=200 and the HCF of (p,q) is 1. So, p and q are co-primes.

Therefore, the requited fraction form is [tex]\dfrac{3053}{200}[/tex].

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).

460, 451,442

Find the 37th term.

Answers

Answer:

136

Step-by-step explanation:

This is an arithmetic sequence

The formula is an = a1 + f × (n-1)

n= the number we are trying to find = 37

a= the number in any given space on the sequence

a1= 460

f= the common difference between the numbers

f= -9 because you subtract 9 from each to get the number

a37= 460-9(37-1)

a37= 460-9(36)

a37= 460- 324

a37= 136

Given :

[tex] \\ [/tex]

The first three terms of a sequence are 460, 451, 442

[tex] \\ [/tex]

To Find :

[tex] \\ [/tex]

37th term of sequence = ?

[tex] \\ [/tex]

Solution :

[tex] \\ [/tex]

Clearly these three terms are making an arithmetic sequence, with :

First term, a = 460 Common difference, d = 451 - 460 = - 9

[tex] \\ [/tex]

Now, we have to find 37th term of sequence = [tex] \tt a_{37}[/tex]

[tex] \\ [/tex]

Now, we know that :

[tex] \large \underline{\boxed{\bf{a_{n} = a + (n-1)d}}}[/tex]

[tex] \\ [/tex]

[tex] \tt : \implies a_{37} = a + (37-1)d[/tex]

[tex] \tt : \implies a_{37} = a + 36d[/tex]

[tex] \\ [/tex]

Now, by substituting values of a and d :

[tex] \tt : \implies a_{37} = 460 + 36 \times (-9)[/tex]

[tex] \tt : \implies a_{37} = 460 - 324[/tex]

[tex] \tt : \implies a_{37} = 136[/tex]

[tex] \\ [/tex]

Hence, value of 37th term of given sequence is 136.
