So the area is 2x3 cm with 68 paramecia.
Not sure if this is the best way to do it, but I’d do 68/2*3 (68 divided by (2 times 3))
So first 2*3 is 6cm.
Now you’re trying to find paramecia/cm2. You are trying to find a unit rate. That is a value over one.
Then because there are 68p and 6cm, to find the unit rate, you’d do 68/6.
Now you have your unit rate, which is 11.3 repeating, or 11 1/3 as a fraction.
That would be 11.3 (11 1/3) paramecia per cm2
also I’m not 100% sure if this is correct, just wanted to help, so no guarantees
Answer:
4
Explanation:
Because the mean time taken to turn from blue/black to orange/brown (in minutes) was the shortest, showing that the rate of reaction was the highest.
Answer:
C. -independent, dependent, intervening
Explanation:
Independent variable is defined as the variable that can be changed during the experiment, dependent variable is the variable which is being tested and whose value depends on independent variable and intervening variable impacts the relationship between a dependent variable and an independent.
So, in the given study, ice cream was an independent variable as it can be changed during study and Howard wants to study its impact, fighting was a dependent variable as it is being tested and the temperature was the intervening variable as it is a cause of independent variable and also impacts the relationship between a dependent variable and an independent.
Hence, the correct option is C. independent, dependent, intervening.
