A factor of 30 is chosen at random. What is the probability, as a decimal, that it is a 2-digit number?
The positive whole-number factors of 30 are:
1, 2, 3, 5, 6, 10, 15 and 30.
So, there are 8 of them. Of these, 3 have two digits. Writing each factor on a slip of paper, then putting the slips into a hat, and finally choosing one without looking, get that
P(factor of 30 chosen is a 2-digit number) = number of two-digit factors ÷ number of factors
=38=3×.125=.375
Hey ! there
Answer:
- Simplest fraction form of 85% is <u>1</u><u>7</u><u>/</u><u>2</u><u>0</u><u> </u><u>.</u>
Step-by-step explanation:
Question says that we have to write the <u>simplest</u><u> </u><u>form </u><u>of </u><u>8</u><u>5</u><u>%</u><u> </u><u>as </u><u>it's </u><u>fraction</u><u> </u><u>.</u>
<u>Solution </u><u>:</u><u> </u><u>-</u>
![\quad \longrightarrow \qquad \:85\%](https://tex.z-dn.net/?f=%20%5Cquad%20%5Clongrightarrow%20%20%5Cqquad%20%5C%3A85%5C%25%20)
We know that ,
- Percent ( % ) = <u>1</u><u>/</u><u>100</u>
So ,
![\quad \longrightarrow \qquad \: 85 \times \dfrac{1}{100} \:](https://tex.z-dn.net/?f=%5Cquad%20%5Clongrightarrow%20%20%5Cqquad%20%5C%3A%2085%20%5Ctimes%20%5Cdfrac%7B1%7D%7B100%7D%20%5C%3A%20)
or ,
![\quad \longrightarrow \qquad \: \dfrac{85}{100}](https://tex.z-dn.net/?f=%5Cquad%20%5Clongrightarrow%20%20%5Cqquad%20%5C%3A%20%5Cdfrac%7B85%7D%7B100%7D)
Reducing the fraction by cancelling it by 5 :
![\quad \longrightarrow \qquad \: \dfrac{ \cancel{85}}{ \cancel{100}}](https://tex.z-dn.net/?f=%20%5Cquad%20%5Clongrightarrow%20%20%5Cqquad%20%5C%3A%20%5Cdfrac%7B%20%5Ccancel%7B85%7D%7D%7B%20%5Ccancel%7B100%7D%7D)
We get :
![\quad \longrightarrow \qquad \: \pink{\underline{\boxed{\frak{\dfrac{17}{20} }}}} \quad \bigstar](https://tex.z-dn.net/?f=%20%5Cquad%20%5Clongrightarrow%20%20%5Cqquad%20%5C%3A%20%20%20%20%20%20%5Cpink%7B%5Cunderline%7B%5Cboxed%7B%5Cfrak%7B%5Cdfrac%7B17%7D%7B20%7D%20%7D%7D%7D%7D%20%5Cquad%20%5Cbigstar)
Now , we can't reduce 17/20 .
- <u>Henceforth</u><u> </u><u>,</u><u> </u><u>1</u><u>7</u><u>/</u><u>2</u><u>0</u><u> </u><u>is </u><u>the </u><u>simplest</u><u> </u><u>form </u><u>of </u><u>8</u><u>5</u><u>%</u><u> </u><u>.</u>

Answer:
2
Step-by-step explanation:
4 2x2 is 4
2x3 is 6
sorry for the long type it says 20 character above
Maybe 50 divided by 25 is 2 so the answer is 2
hope i helped :D : D
Consider the number of the adult tickets is x
X+2x=276
3x=276
X=92
So the student tickets is =184
