Answer:

3. \frac{1}{12}

4. \frac{22}{3}

5. \frac{5}{42}

8. \frac{8}{63}

9. -\frac{7}{54}

10. -\frac{3}{16}

Step-by-step explanation:

3.

\frac{-6}{8} *\frac{1}{-9} =\frac{-6}{-72}

ahora simplifica, un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 6

\frac{1}{12}

4.

\frac{11}{3}*\frac{4}{2} =\frac{44}{6}

ahora simplifica, los dos nu$meros se pueden simplificar por 2

\frac{22}{3}

5.

\frac{5}{-3}*\frac{-2}{7}* \frac{1}{4} =\frac{-10}{-84}

ahora simplifica, un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 2

\frac{5}{42}

8.

\frac{20}{-5}*\frac{1}{-9}* \frac{-2}{-7} =\frac{-40}{-315}

ahora simplifica, un numero multiplicado por otro negativo se convierte en positivo. Un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 5

\frac{8}{63}

9.

\frac{2}{3}*\frac{-7}{-9}* \frac{-1}{4} =\frac{14}{-108}

ahora simplifica, un numero multiplicado por otro negativo se convierte en positivo. Un numero positivo dividido por un numero negativo se convierte en negativo. Los dos nu$meros se pueden simplificar por 2

-\frac{7}{54}

10.

\frac{9}{-12}*\frac{-4}{16} =\frac{-36}{-192}

ahora simplifica, un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 12

-\frac{3}{16}

Espero y te ayude esto! (:

If n is a positive integer, how many 5-tuples of integers from 1 through n can be formed in which the elements of the 5-tuple ar
sleet_krkn [62]

This question is incomplete, the complete question is;

If n is a positive integer, how many 5-tuples of integers from 1 through n can be formed in which the elements of the 5-tuple are written in increasing order but are not necessarily distinct.

In other words, how many 5-tuples of integers  ( h, i , j , m ), are there with  n ≥ h ≥ i ≥ j ≥ k ≥ m ≥ 1 ?

Answer:

the number of 5-tuples of integers from 1 through n that can be formed is [ n( n+1 ) ( n+2 ) ( n+3 ) ( n+4 ) ] / 120

Step-by-step explanation:

Given the data in the question;

Any quintuple ( h, i , j , m ), with n ≥ h ≥ i ≥ j ≥ k ≥ m ≥ 1

this can be represented as a string of ( n-1 ) vertical bars and 5 crosses.

So the positions of the crosses will indicate which 5 integers from 1 to n are indicated in the n-tuple'

Hence, the number of such quintuple is the same as the number of strings of ( n-1 ) vertical bars and 5 crosses such as;

\left[\begin{array}{ccccc}5&+&n&-&1\\&&5\\\end{array}\right] = \left[\begin{array}{ccc}n&+&4\\&5&\\\end{array}\right]

= [( n + 4 )! ] / [ 5!( n + 4 - 5 )! ]

= [( n + 4 )!] / [ 5!( n-1 )! ]

= [ n( n+1 ) ( n+2 ) ( n+3 ) ( n+4 ) ] / 120

Therefore, the number of 5-tuples of integers from 1 through n that can be formed is [ n( n+1 ) ( n+2 ) ( n+3 ) ( n+4 ) ] / 120
