Step-by-step explanation:
x = amount of shares for $6.25
y = account of shares for $6.50
x + y = 500
x×6.25 + y×6.5 = 3218.75
x = 500 - y
(500 - y)×6.25 + y×6.5 = 3218.75
3125 - y×6.25 + y×6.5 = 3218.75
0.25×y = 93.75
y = 375
x = 500 - 375 = 125
so, he bought
375 shares of $6.50
125 shares of $6.25

Answer:
Symmetric
Step-by-step explanation:
In the stem and leaf plot above which represents the current sale prices of houses in dollars, we can observe the shape of the distribution seem like that of a bell shape. Most of the data values are concentrated towards the center compared to the concentration at both extremes.
This implies that most of the current sales price is centered close to the median price of roughly 49/50 dollars.
Therefore, the distribution of housing price can be described as roughly symmetric.
