Answer:
Step-by-step explanation:
Given that Jade invested in the stock market.
The weekly change in value of her stock, in dollars, over 4 weeks was +23.65, -22.20, -12.75 and +5.98.
The average weekly change in value of Jade's stock is given by [tex]Average=\frac{sum of the weekly changes in value of her stock in dollars}{total number of weeks}[/tex]
[tex]Average=\frac{23.65+(-22.20)+(-12.75)+5.98}{4}[/tex]
[tex]=\frac{23.65-22.20-12.75+5.98}{4}[/tex]
[tex]=\frac{29.63-34.92}{4}[/tex]
[tex]=\frac{-5.29}{4}[/tex]
[tex]=-1.3225[/tex]
Therefore Average=-1.3225
