Let us say that:
x = the number of T shirts bought = 4
y = the number of leather jackets bought = 1
a = the price of the T shirts
b = the price of the leather jackets
With the given variables, we can say that the total cost
is:
total cost = a x + b y
Since, b = 6 a, therefore:
total cost = a x + 6 a y
total cost = a (x + 6 y)
Since total cost is 209, therefore we can calculate for a
since x and y are also given:
209 = a (4 + 6 * 1)
209 = a (10)
a = $20.9
<span>Therefore each T shirt cost $20.9</span>
Using the probability concept, the correct statement is:
B. P(hibiscus|red) = P(hibiscus).
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
For item a, the probabilities are:
- P(yellow|rose) = 45/105 = 0.4286.
- P(yellow) = 135/315 = 0.4286.
Same probabilities, hence the statement that they are different is false.
For item b, the probabilities are:
- P(hibiscus|red) = 80/120 = 2/3.
- P(hibiscus) = 210/315 = 2/3.
Equal, hence this is the correct statement.

It would be 3 since the equation has y but no x
Factor out the 12 from the expression
12(z+3)
So prime factorization is as it seems, finding the prime factors for a number. With this number, break it down as such:
<u>Looking at our factors, the prime factorization of 6400 is
