Answer:
7
Step-by-step explanation:
15+-8=7
To solve this problem, we have to set up an equation. Let the variable x represent the number of books that Dimitrius had before last week.
x - 5 - 3 + 8 = 12
To begin simplifying this equation, lets combine terms on the left side of the equation.
x - 8 + 8 = 12
The -8 and +8 cancel each other out, leaving us with:
x=12
Therefore, Dimitrius had 12 books before last week.
Hope this helps! :)
The expected value that this broker assign to this stock's end-of-the-year price is $58.50.
Using this formula
Expected value=Stock worth at $50+ Stock worth at $60+ Stock worth at $70
Where:
Stock worth at $50=40% chance
Stock worth at $60=35% chance
Stock worth at $70=25% chance
Let plug in the formula
Expected value=(40%×$50)+($35%×$60)+($25%×$70)
Expected value=$20+$21+$17.5
Expected value=$58.50
Inconclusion the expected value that this broker assign to this stock's end-of-the-year price is $58.50.
