Answer:

The required probability is 0.462.

Step-by-step explanation:

Probability to play the song = 6/7

Probability not to play the song = 1 - 6/7 = 1/7

Required probability  

= Probability to play 5 days x probability not to play 1 one + Probability to play 6 days

=\left (\frac{6}{7}  \right ) ^5\times \frac{1}{7} + \left (\frac{6}{7}  \right ) ^6\\\\= \frac{6^5 +6^6}{7^6}\\\\=0.462

Answer:

2, 6, 28, 358.01

Step-by-step explanation:

We have to find the fractions of whole numbers.

Number 1:

\frac{1}{5} of 10 = \frac{1}{5} \times (2 \times 5) = 2 (Answer)

Number 2:

\frac{2}{3} of 9 = \frac{2}{3} \times (3 \times 3) = 2 \times 3 = 6 (Answer)

Number 3:

\frac{7}{8} of 32 = \frac{7}{8} \times (4 \times 8) = 7 \times 4 = 28 (Answer)

Number 4:

3 \times 10^{2} + 5 \times 10^{1} + 8 \times 10^{0} + 1 \times \frac{1}{10^{2} }

= 3 \times 100 + 5 \times 10 + 8 \times 1 + \frac{1}{100} {Since a^{0} = 1}

= 300 + 50 + 8 + 0.01

= 358.01 (Answer)

7. The difference of Grandma Annie's age and twice Carl's is 22. Gran

<h2>Systems of Equations Word Problems</h2>

To solve these questions, we can translate key words into operations:

  • <em>Difference</em> = subtract
  • <em>Twice</em> = double
  • <em>Less than</em> = subtract

<h2>Solving the Question</h2>

We're given:

  • Difference of Annie's age and twice Carl's age is 22
  • Annie's age is 13 less than 3 times Carl's age

There are two variables given two us: Annie's age and Carl's age.

  • Let Annie's age be equal to <em>x.</em>
  • Let Carl's age be equal to <em>y</em>.

Translate the given information into two equations:

  • Difference of Annie's age and twice Carl's age is 22
    ⇒ x-2y=22
  • Annie's age is 13 less than 3 times Carl's age
    ⇒ x=3y-13

Now, we can substitute the fist equation into the second one to solve for <em>y</em>:

(3y-13)-2y=22\\3y-13-2y=22\\y-13=22\\y=35

Now, substitute <em>y</em> back into the second equation to solve for <em>x</em>:

x=3y-13\\x=3(35)-13\\x=105-13\\x=92

<h2>Answer</h2>

Therefore, Grandma Annie is 92 years old.

I attended a funeral once in Pickens county in my State.... They buried him in the midst of a marble quarry: they cut through so
UNO [17]

Answer:

C

Step-by-step explanation:

Now we have improved on that. We have got the biggest marble-cutting establishment on earth within a hundred yards of that grave. We have got a half-dozen woolen mills right around it, and iron mines, and iron furnaces, and iron factories. We are coming to meet you. We are going to take a noble revenge, as my friend, Mr. Carnegie, said last night, by invading every inch of your territory with iron, as you invaded ours twenty-nine years ago.
