Black_prince [1.1K]

Answer:

\frac{4}{21}

Step-by-step explanation:

Another way of phrasing this question is this; if only two bills are selected without replacement, what is the probability that at one of the two bills will be a $10 bill:

P(One $10 bill) = P(picking a $10 bill first then another type) + (picking another

                            type then a $10 bill)

                        = \frac{5}{15}*\frac{10}{14}+\frac{10}{15} *\frac{5}{14} = \frac{4}{21}

Solve y – 7 > 3 + 2y A) y -10 D) y > -10
Anika [276]

Answer:

D. -y > 10

Step-by-step explanation:

First, move the variable (+ 2y) to the left-hand side and change its sign.

y - 2y - 7 > 3

Then, move the constant (+ 7) to the right-hand side and change its sign.

y - 2y > 3 + 7

Then, collect the like terms (y - 2y)

-y > 3 + 7

Finally, add the numbers (3 + 7). That will get you your final answer.

-y > 10
