Your equation is:
x² + y² = 15
Answer:
The required probability is 0.048
Step-by-step explanation:
Consider the provided information.
Out of 52 card we need to select only 2.
Therefore the sample space is: 
One card is Ace. The number of Ace are 4 and we need to select one of them.
This can be written as: 
The second card can be Ten or a Jack or a Queen or a King.
There are 4 Ten, 4 jack, 4 Queen, and 4 king in a deck and we need to select only 1 out of them.
So we can say that we need to select 1 card out of 16.
This can be written as: 
Thus, the probability that one of the cards is an ace and the other one is either a ten, a jack, a queen or a king is:

Hence, the required probability is 0.048
Answer: Either A or B
Step-by-step explanation:
Both A and B are the same answers, but the main answer should be
c+d=17, 4c+2d =54
C represents the number of cows and D represents the number ducks. The two and fours in front of the variables represents the number of legs the repesctive animal has.
c+d would mean how many animals are in the barn. Feel free to clarify the two same answers
(ab + 174)/3 <115
multiply by 3 on each side
ab + 174 < 345
subtract 174 from each side
ab < 171
248+ ab >366
subtract 248 from each side
ab> 118
Answer 118< ab < 171
