Answer:
Fraction = 13/20
Decimal = 0.65
Percent = 65%
Step-by-step explanation:
<em><u>Given:</u></em>
13 out of 20 emails in mail inbox are junk emails
<em><u>Solve for:</u></em>
The experimental probability that next email is junk
<em><u>Solution:</u></em>
Step 1: Define the formula for calculating the probability
P = number of elements/total number of elements
Step 2: Perform the calculation
The number of elements (junk emails) = 13
The total number of elements (all emails) = 20
=> P(obtain odd number in experiment) in fraction form = 13/20
=> P(obtain odd number in experiment) in decimal from = 0.65
=> P(obtain odd number in experiment) in percent form = 0.65 x 100 = 65%

The scientific notation is 5.09 x 10^5
Eliminate parenthesis: Y+5+3y-9
Subtract the numbers: Y-4+3y
Combine like terms: y-4+3y
4y-4
Common factor: (y+5)+(3y-9)=4(y-1)
Solution: 4(y-1)
