Choose an integer from 1 to 2400 , what is the probabilty that the integer can not be divided by 6 and 8?

Answers

Answer:

P=633/800

Step-by-step explanation:

The total number of integers from 1 to 2400  is 2400.

As understand we are looking for the numbers which can  be divided at least by one of the numbers 6 or 8. Lets call all integers which can be divided by 6 or by 8 " black" integers and others " white" integers.

For example 6 can be  divided by 6, however can not be divided by 8.  However it is divided by 6 so we have to  6 belongs to " black" untegers.

The number of integers which can be divided by 6 is

2400:6=400 (1st sheet of black integers)

The number of integers which can be divided by 8 is 2400:8=300 (2nd shhet of black numbers).

So total amount of " black" integers= 400+300=700.  However some of these integers can be divided both as by 6 as by 8.

These integers heve been included as to sheet 1 as to sheet 2. ANother words these integers have been included twice.  SO we have to find the

total number of such integers and deduct them from 700.

These are the integers as follows:

3*4*2=24

3*4*3=36

3*4*4=48

3*4*5=60

3*4*6=72 ...

So these is any integer from 1 to 2400 which can be divided by 12 but own 12.

The number of such integers is:

2400:12-1=200-1=199

So the number of black integers is 700-199=501

That means that the number of white integers is 2400-501 = 1899

The required probability is P=1899/2400=633/800

After writing a $800 check to pay a bill, a student had a balance of $350 in his account. How muchdid he have in the account before he wrote the check?
a) Let X = his balance before writing the check. Write the equation you would use to solve this
problem.

Answers

The equation to solve the problem is X  - $800 = $350. And the amount in his account before he wrote the check is $1150.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that after writing an $800 check to pay a bill, a student had a balance of $350in his account.

We need to find out how much did he have in the account before he wrote the check.

The amount of the check = $800

The amount the student has in balance = $350

The amount the student had before he wrote the check.

Let X be the amount the student had before the check.

Now,

X  - $800 = $350

X - 800 = 350 is our equation to find the amount the student has before the check.

The value of X can be written as,

We have,

X  - $800 = $350

Add $800 on both sides

X = $350 + $800

X = $1150

Hence, the equation to solve the problem is X  - $800 = $350. And the amount in his account before he wrote the check is $1150
