Answer:
(x, y) = (2, 5)
Step-by-step explanation:
Double the second equation and subtract the first:
2(7x +y) -(3x +2y) = 2(19) -(16)
11x = 22
x = 2
In the second equation, ...
7(2) +y = 19
y = 19 -14 = 5
The solution is (x, y) = (2, 5).
10 quarters....5 nickels......15 in total
probability of picking a nickel first is 5/15 which reduces to 1/3
without replacement
probability of picking a quarter next is 10/14 which reduces to 5/7
probability of both is : 1/3 * 5/7 = 5/21 <==
There are dependent events being that u didn't replace what u picked <==
<span>For Part A:
A marble can have only one color, so you cannot choose a marble that is both black and red. Therefore the events are mutually exclusive (cannot happen simultaneously)

I hope my answer has come to your help. God bless and have a nice day ahead!
