Answer 1

The average weekly change in value of Jade's stock in dollars is -1.3225

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.

To find the average weekly change in value of her stock in dollars :

The average weekly change in value of Jade's stock is given by
`Average=(sum of the weekly changes in value of her stock in dollars)/(total number of weeks)`

`Average=(23.65+(-22.20)+(-12.75)+5.98)/(4)`

`=(23.65-22.20-12.75+5.98)/(4)`

`=(29.63-34.92)/(4)`

`=(-5.29)/(4)`

`=-1.3225`

Therefore Average=-1.3225

Therefore the average weekly change in value of Jade's stock in dollars is -1.3225
