Answer:
22%
Step-by-step explanation:
theres 2 green marbles and 9 marbles in total
2/9=0.2222222
1 + 5 = 6
3 + 3 = 6
3 + 47 = 50
7 + 43 = 50
13 + 37 = 50
19 + 31 = 50
keeping in mind that 4 months is not even a year, since there are 12 months in a year, 4 months is then 4/12 years.
let's assume is simple interest.

Answer:
2=y
4=x
Step-by-step explanation:
x=2y
y=2y-2
add 2 to both sides
2+y=2y
subtract y from both sides
2=1y
2=y
Answer:
Timed test.
Step-by-step explanation:
An operational definition gives exactly what the independent variable means and its mode of measurement. The Independent variable is the variable in a research or experimental study which causes a change in the the measured variable. Hence, the independent variable is the predictor variable. In the study above, the independent variable is the timed test which is used to observe changes in the heart rate of the test taker (test anxiety). The change innheartrate of the test taker is the dependent variable.
