Tan(52°) = opposite/adjacent = x/35 ⇒
x = 35 * tan(52°) = 35 * 1.2799 ≈ 44.80
ANSWER
My answer is in the photo above
EXPLANATION
For all the equations I have used the cross multiplication method although you can also use the LCM method
Expected value E(x) = 0.9994(150000 - 181) = 0.9994 x 149819 = $149,729.11
Answer: Look for the inner answer inside u!
Step-by-step explanation:
Try to get the u’s on one side so for this to happen, you would subtract the four from both sides.
u - 4u = 7 - 4
combine like terms
-3u = 3
divide by -3
u = -1
