Anastasy [175]

Answer:

<h3>The average weekly change in value of Jade's stock in dollars is -1.3225</h3>

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.

<h3>To find the average weekly change in value of her stock in dollars :</h3>

The average weekly change in value of Jade's stock is given by $Average=\frac{sum of the weekly changes in value of her stock in dollars}{total number of weeks}$

$Average=\frac{23.65+(-22.20)+(-12.75)+5.98}{4}$

$=\frac{23.65-22.20-12.75+5.98}{4}$

$=\frac{29.63-34.92}{4}$

$=\frac{-5.29}{4}$

$=-1.3225$

Therefore Average=-1.3225

<h3>Therefore the average weekly change in value of Jade's stock in dollars is -1.3225</h3>
