Answer:
The answer to your question is the letter D.
Step-by-step explanation:
Equation
(x + 5)/(x² + 7x + 10) = (x - 4)/ (x² - 2x - 8)
Process
1.- Factor both denominators
x² + 7x + 10 = (x + 5)(x + 2)
x² - 2x - 8 = (x - 4)(x + 2)
2.- Substitute
(x + 5) / (x + 5)(x + 2) = (x - 4)/(x - 4)(x - 2)
3.- Simplify
1/(x + 2) = 1/(x - 2)
4.- Solve for x (cross multiplication)
x - 2 = x + 2
x - x = 2 + 2
0 = 4
5.- Conclusion
The solution is all real numbers except -5, -2 and 4.
Answer:
9/40
Step-by-step explanation:
The probability of event A happening, then event B, is the probability of event A happening times the probability of event B happening given that event A already happened.
In this case, event A is the Captain missing the pirate ship and event B is the pirate hitting the Captain's ship.
The Captain fires first, so her ship can't be sunk before she fires her cannons.
So, the probability of the Captain missing the pirate ship is
3/5
If the Captain missed the pirate ship, the pirate has a normal chance to fire back.
So, the probability of the pirate hitting the Captain's ship given the Captain missing the pirate ship is
3/8
The probability that the Captain misses the pirate ship, but the pirate hits is then the probability of the Captain missing the pirate ship times the probability of the pirate hitting the Captain's ship given the Captain missing the pirate ship.
this is 3/5 X 3/8 = 9/40

Step-by-step explanation:
I think it means every data value should be equal to the "mean" to make the standard variation of this set to be zero. Or all data value of the set are equal.
