The question is too small but make a bigger photo and I’ll answer it
Answer:
x = -3; y = 2
Step-by-step explanation:
5x + 2y + 19 = 0
3x + 4y + 17 = 0
-10x - 4y - 38 = 0
3x + 4y + 17 = 0
-7x - 21 = 0
x = -3
5(-3) + 2y = -19
2y = -4
y = -2
Answer: x = -3; y = 2
Infinite series can either be convergent or divergent. It is convergent if the series has a limit and would approach a certain real number. It is divergent if it has no limits.
The given above is a series that is comprised of whole numbers and can go as large as the positive infinity. Because of this, the answer to this item is Divergent.
Since there is a 70% chance of making $12,000 so have that:
.70 × 12000 = 8400
Also, we have a 10% chance of breaking even, so we also have that:
.10 × 0 = 0
Finally, we have a 20% chance of losing $7400 so we also have that:
.20 × 7400 = 1480
Thus, putting it all together we have:
.70(12000) + .10(0) + .20(7400) = 8400 + 0 + 1480 = 9880
Therefore, the expected value is:
$9880
Answer:
The answer to your question is 12 moles of water.
Step-by-step explanation:
Reaction
2 O₂ + CH₄ ⇒ CO₂ + 2 H₂O
If Oxygen is in excess, then the limiting reactant is methane and we calculate the moles of water produced considering the moles of methane.
1 mol of methane -------------- 2 moles of water
6 moles of methane --------- x
x = (6 x 2) / 1
x = 12 moles of water
