Answer:
x=34
y=17
Step-by-step explanation:
Let Paula's score be= x
Let Maria's score be=y
<u>Given</u><u>:</u>
x=2y
x+y=51
<u>Substitution</u><u>:</u>
2y+y=51
<u>Formula</u><u>:</u>
2y+y=51
3y=51
y=17
x=2y
x=2(17)
x=34
<u>Proof</u><u>:</u>
x+y=51
34+17=51
51=51
Hope this helps ;) ❤❤❤
Use the conditional probability formula, P(a|b) = P(a and b)/P(b)
If 14 out of 20 is correct, then that is : 14/20 = 0.70 = 70%

Answer:
On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?
That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)
