Step-by-step explanation:
you would start by replacing the "x" with the 9
subtract the 15 and 9
then that would equal 6 which in this case it would be equal to
I'm pretty sure (sorry if it is wrong)
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.
To do this you have to divide 135 miles by 5 hours. You will get the answer of 27 miles per hour.
If I read correctly, 2456 pennies needs to be divided simply by 3 then rounded to the nearest hundredth. So you would do 2456/3 3 goes into 24 how many times? Then 3 goes into 5 how many times, then continue the pattern. Once you've gotten a decimal to the thousandth, round the number to the hundredth and there you go
Lne equals 1 because they cancel each other out. e is the base of ln.
For example: log has a base of 10, log10 = 1
