If it doubles each year, it means that the next year the number will be 2 times its size.
So if in 2005, the number of users is 2 million, then in 2006 the number of users will be 2 times the number in 2005.
Knowing this, we then know that the year 2004 will be half the users of 2005. Then the year 2003 will be half the users of 2004 and so forth.
So you solve for each year as such:
2005: 2
2006: 2 x 2 = 4
2007: 4 x 2 = 8
2008: 8 x 2 = 16
2009: 16 x 2 = 32
2004: 2 / 2 = 1
2003: 1 / 2 = 0.5
2002: 0.5 / 2 = 0.25
2001: 0.25 / 2 = 0.125
Answer:
Advantages:
- It is easier for people to choose an option rather than to write an essay. The questionnaire reflects what the person is thinking and what the person's point of view is, which as a result makes it easier to analyze and conclude results
- A wide range of questions can be asked within one questionnaire, which makes it an effective way to conduct a survey/test
Disadvantages:
- A person has to read carefully in order to answer each question and sometimes there is lack of concentration by the person filling in the questionnaire
- It is slightly difficult to write an effective questionnaire, that would able to test a vast knowledge/ conduct a survey so that an effective analysis can be done

When repeated:
it has
5 ways for each
different five digit members can be formed from the digits:5*5*5*5*5=<u>3125</u>
When not repeated:
it has
5 ways for 1st
4 ways for 2nd
3 ways for 3rd
2 ways for 4th
1 ways for 5th
different five digit members can be formed from the digits:5*4*3*2*1=<u>120</u>
Answer:
x= -9
Step-by-step explanation:
Answer:
5:3
Step-by-step explanation:
to simplify this equation we have to find something that both numbers can be divided by
both numbers can be divided by 7
so when we divide the numbers we get
5b = 3c
so basically the ratio is 5:3
