Answer:
Option B is right
Step-by-step explanation:
Given that in the graduating class of a certain college, 48 percent of the students are male and 52 percent are female. In this class 40 percent of the male and 20 percent of the female students are 25 years old or older.
Males Females
48% 52%
25 or more
age 40% 20%
One student in the class is randomly selected,
to find the probability that he or she will be less than 25 years old
= Prob (male and less than 25 years old)+Prob (female and less than 25 years old)
(since mutually exclusive and exhaustive)
= 
After rounding off to 1 one decimal
we get 0.7

Step-by-step explanation:
but just put seven and hope for the best
To find the slope of a linear equation, we rearrange the equation into the format y = mx + b
5x - 12y = 24 // Equation given
5x - 12y + 12y = 24 + 12y // Add 12y on both sides
5x = 24 + 12y // Simplify
5x - 24 = 24 + 12y - 24 // Subtract 24 from both sides
5x - 24 = 12y // Simplify
12y = 5x - 24 // Switch sides to make y the subject
12y ÷ 12 = (5x - 24) ÷ 12 // Divide by 12 on both sides
y = 5/12 x - 2 // Simplify
Once we write the equation in this format, we match it against the general equation y = mx + b
we can conclude that m = 5/12
Therefore the slope is 5/12
