Step-by-step explanation:
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
Let
x---------> size of the event space
y-------> size of the sample space

means that when you subsituted g(x) for x in g(x), you got 16x-15
a(ax+b)+b=16x-15
distribute
xa^2+ab+b=16x-15d
we look at the x terms
therefor
xa^2=16x
a^2=16
a=-4 or 4
we will find out
look a constant terms
ab+b=-15
undistribute b
b(a+1)=-15
if a is -4 then
b(-4+1)=-15
b(-3)=-15
b=5
if a=4 then
b(4+1)=-15
b(5)=-15
b=-3
so
g(x)=-4x+5 or
g(x)=4x-3
if a=-4, b=5
if a=4, b=-3

Answer: Lucy will have a total of $56.15 left after buying the E-Book.
Step-by-step explanation:
To find the answer, you will need to add together the total amount of money Lucy received from every one for her birthday.
After getting the total by using addition, you will need to use subtraction to get the answer for the total remaining money.
$20.00 + $15.00 + $32.00 = $67.00
$67.00 - $10.85 = $56.15
