X^2 = 4x + 12
x^2 - 4x - 12 = 0, use the quadratic equation
Solve for x over the real numbers:
(x - 6) (x + 2) = 0
Split into two equations:
x - 6 = 0 or x + 2 = 0
Add 6 to both sides:
x = 6 or x + 2 = 0
Subtract 2 from both sides:
Answer: x = 6 (or x = -2 only positive solution)
Step-by-step explanation:
y = 106° { being opposite angles of parallelogram }
12x - 9 = 10x + 7 ( being opposite sides of parallelogram)
12x - 10x = 7 + 9
2x = 16
x = 8
Hope it will help however the image wasn't clear i figured out by guessing .
Answer:
i) 25.25%
ii) 2.28%
Step-by-step explanation:
In this case we can use a normal distribution calculator. Setting the mean as 210000 and the standard deviation as 15000, we find that the area below 200000 is 0.2525. So the probability that the condominium will sell at $200.000 is 25.25%.
The area above 240000 is 0.0228, so the probability that the condominium will sell at $240.000 is 2.28%
