First we need to multiply to make the fractions have equal denominators so we can add/subtract.
math: 1/3 x 4/4=4/12
science: 1/4 x 3/3=3/12
Now we can find the time she spent on history (I assume this is what you are looking for)
Total time-math time<span>-science time=history time</span>
12/12-4/12-3/12
=5/12
Amy spent 5/12 of her time working on history.
Answer:

Step-by-step explanation:
-8x+2=-7x+10
-x+2=10
-x=8
x=-8
The average winning per bet is the mean or the expected value of winning a bet.
The statistical term that represents $0.94 is (c) the expected value
From the question, we understand that the gambler has an average winning of $0.94, when he places a bet of $1
This means that:
The average winning on a bet of $1 is $0.94
Average, in statistics means the mean or expected value
Hence, the statistical term for $0.94 is (c) the expected value
