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:
6) y = -7x +11
8) y = -1/3x -1
10) y = 5/4x -2
Step-by-step explanation:
It is convenient to start with a point-slope form of the equation.
y = m(x -h) +k . . . . . line with slope m through point (h, k)
__
6) m = -7, (h, k) = (2, -3)
y = -7(x -2) -3 = -7x +14 -3
y = -7x +11
__
8) m = -1/3, (h, k) = (-3, 0)
y = (-1/3)(x -(-3)) +0
y = -1/3x -1
__
10) m = 5/4, (h, k) = (4, 3)
y = 5/4(x -4) +3 = 5/4x -5 +3
y = 5/4x -2

Answer:
We all watched NASA's space shuttle videos where the announcer names the countdown "T-5 hours". That means that there are 5 hours till the liftoff. Why not input your own data and see how many hours left till your final countdown? Use this time calculator for making fast and effective hours from now calculator.
