1 answer:

8 0

$\dfrac{1}{4} \div \dfrac{2}{4}$

------------------------------------------------------------------------
Change the divide fraction to multiplication fraction :
------------------------------------------------------------------------

$\dfrac{1}{4} \times \dfrac{4}{2}$

------------------------------------------------------------------------
Combine into single fraction :
------------------------------------------------------------------------

$\dfrac{4}{8}$

------------------------------------------------------------------------
Reduce to simplest form :
------------------------------------------------------------------------

$\dfrac{4 \div 4}{8 \div 4} = \dfrac{1}{2}$

How many positive integers between 1000 and 9999 inclusive

bekas [8.4K]

Answer:

Step-by-step explanation:

first number is 1000-1+9=1008

9)1000(1

-------

-----

----

last number is 9999

9| 9999

---------

1111 |0

--------

9999=1008+(n-1)9

9999-1008=(n-1)9

n-1=8991/9=999

n=999+1=1000

first digit=1000

last digit=9999-1=9998

2 |9999

---------

|4999|1

9998=1000+(n-1)2

(n-1)2=9998-1000=8998

n-1=4499

n=4499=1=5000

c.not sure

total numbers=9000

9999=1000+(n-1)1

9999-1000=n-1

n=8999+1=9000

numbers divisible by 3=3000

first number=1002

last number=9999

9999=1002+(n-1)3

(n-1)3=9999-1002=8997

n-1=2999

n=2999+1=3000

numbers not divisible by 3=9000-3000=6000

numbers divisible by 5=1800

first number=1000

last number=9995

9995=1000+(n-1)5

(n-1)5=9995-1000=8995

n-1=1799

n=1799+1=1800

numbers divisible by 7=1286

A linear congruence generator is an algorithm that returns a sequence of pseudorandom numbers computed using discontinuous piecewise linear equations. This method is one of the oldest and best-known pseudorandom number generator algorithms.

The linear congruential generator (LCG) is a pseudorandom number generator (PRNG ) is a class of algorithms. Random number generation plays an important role in many applications, from cryptography to Monte Carlo methods.
