Given expression:
To simplify the expression as a fraction in simplest form, let us multiply both terms by 10. Then, both terms must also be divided by 10.
![\implies \dfrac{[10(0.8) - 10(0.6)]}{10}](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac%7B%5B10%280.8%29%20-%2010%280.6%29%5D%7D%7B10%7D)
![\implies \dfrac{[8 - 6]}{10}](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac%7B%5B8%20-%206%5D%7D%7B10%7D)
![\implies \dfrac{[2]}{10} = \dfrac{2}{10}](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac%7B%5B2%5D%7D%7B10%7D%20%3D%20%5Cdfrac%7B2%7D%7B10%7D)
When 2/10 is simplified in lowest terms, we get;

Therefore, 0.8 - 0.6 in fraction form is 1/5.
Answer:
The null hypothesis is 
Step-by-step explanation:
According to the Centers for Disease Control and Prevention, the proportion of U.S. adults age 25 or older who smoke is .22
This means that at the null hypothesis, it is tested if the proportion is in fact 0.22, that is:

A researcher suspects that the rate is lower among U.S. adults 25 or older who have a bachelor's degree or higher education level.
At the alternative hypothesis, it is tested if the proportion is lower than 0.22, that is:

Answer:about 250
Step-by-step explanation:
It’s because I go to base ball games all the time and I asked before
Well, sometimes it is needed in word form. If someone asks you how much money you need in debt, you might say 1 tenth 4 hundredths. That is why you might need to read 0.203 as 2 tenths 3 thousandths.
