If she does not ride the ferry she won't pay
This shows that the paying depends on riding.
Thus riding is independent variable and cost is dependent....

Answer:
c. Weights of babies are normally distributed
Step-by-step explanation:
The research has been conducted to identify the weight of new born babies in comparison to the weight of their mother. The samples are collected from young mothers who are at age of 16 to 18. The babies average weight turned out to be 7.3 pounds. It is assumed that the weight of babies is normally distributed.
17 points after 0, 11 points after 0, and 2 points after 0
$24 in 6 hours.
6 hours = $24
1 hour would be: $24/6 = $4
8 hours would then be: $4 * 8 = $32.
So he would make $32 in 8 hours.
Hope this explains it.
