Answer:
Independent Variable- size of aquariums
Dependent variable - number of surviving fish
Controls: nil
Step-by-step explanation:
In every experiment, the independent variable is manipulated and its effect on the dependent variable is observed as certain factors are kept constant.
In this study, the independent variable is the size of the aquariums. As this factor is manipulated, the number of surviving fish (dependent variable) changed accordingly. There was no mention of a control group in the experiment.
However, temperature, amount of food and type of food were held constant for all the experimental groups.
Answer:
To find probability, divide the number of times an event happens by the number of trials.
Find the value in Australian dollars for each exchange rate.
<span>1st exchange rate: </span>
<span>14000/6.21= $2254.43 </span>
<span>2nd exchange rate: </span>
<span>14000/6.37= $2197.80 </span>
<span>Find the difference between the two: </span>
<span>$2254.43 - $2197.80 = $56.63 </span>
Since the first value is greater than your second one Aggie lost money and your answer is <span>It decreases by $56.63.</span>
Answer:
I believe the correct answer is A
Step-by-step explanation:
Why did both of their names have to start with the same letter
x=jay hours
y=jamie huours
x=10+3y

so
43=10+3y
minus 10
33=3y
divide 3
11=y
