Answer:

Step-by-step explanation:
This sequence is geometric because while x is going up by 1, the y sequence has a common ratio.
That is, term/previous equals same number per consecutive y terms.
So 1/2=2/4=4/8 is the common ratio.
The first term is when x=1. We can find this y by figuring out what we can multiply to our common ratio, 1/2, to get the next term,8.
Since 8(2)=16, then the first term is 16.
In general,

Or if preferred:

where
is first term and
is common ratio.

Z score for History:

z score for english:

z score for math:

z score for science:

Since the z score for Math is highest, therefore, in Math class Julie's score is highest.
