Answer:
64% or 16/25
Explanation:
To calculate probability, we first find the fraction for the number of books that are fiction.
![80= \frac{4}{5}](https://tex.z-dn.net/?f=80%3D%20%5Cfrac%7B4%7D%7B5%7D)
To find out what the probability of choosing a fiction book twice, we multiply 4/5 with 4/5 to get our probability if we selected a book twice.
The probability of choosing two fiction books is a 16/25, or 64% chance.
Answer:To find the equation of a parallel line, we first need to find the slope of 3y + 7 = 2x.
We need to find it because, if two lines are parallel, then that means they have the same slope.
The best way to do this is solve for y
Due to the rule that in y = mx + b, m = the slope, we find that the slope is 2/3.
Now we use that slope in the same formula to find b of the line we're trying to find the equation for, and then we'll have our answer. We find b by plugging in (2, 6) for x and y
So our line is: y=2/3x+14/3
