The expected value of a distribution is considered as a mean, or average, for a probability distribution. It represents the center of the possible values of a variable. That doesn't necessarily mean it would be one of the possible values of x.
Answers:
4 goes in the first box
-2x+8 goes in the second box
===========================================================
Explanation:
This piecewise function has 3 separate components to it:
- The left-most piece is the line labeled with 2x+4. This is why it's listed first in the algebraic definition (i.e. your teacher already filled this part out for you). This piece applies only when -2 <= x < 0
- The center piece is y = 4. We leave the "y = " portion out and simply write 4 as the center piece. This says that the output is 4, but only when 0 <= x < 2. That will graph out a flat horizontal portion as the graph shows.
- Lastly, the right-most piece is the line y = -2x+8. Again, we leave off the y portion and just write -2x+8. This piece only applies when 2 <= x < 4
Side note: Something like 2 <= x is another way of saying

Step-by-step explanation:
e^ln x - ln xy is equal to (a) y (b) 1/y (c) x (d) 1/x (e) none of these Which of the following equations is equivalent to the equation y = 5^x? (a) y = ln(5x) (b) y = e^5 ln x (c) y = e^x ln 5 (d) y = x ln 5 (e) none of these When $400 is invested in an account that earns 7.5% annualinterest, compounded quarterly, the accumulated value after 5 years (to the nearest cent) is (a) $581.99 (b) $579.98 (c) $574.25 (d) $550.00 (e) none of these
6 2/5 is the answer, because 15 1/2 divided by 2 2/5 is 6 2/5
