Answer:
Independent variable: type of shoe
Dependent Variable: running speed
TWO controlled variables: same running distance, same runner
Control Group: running with the regular Nike shoes
Experimental Group: running with the new Nikespeed shoes.
Explanation:
According to this question, Molly wants to test her new NikeSpeed running shoes that claim to make her run faster than her regular Nike shoes.
- Independent variable is the variable of an experiment that is subjected to change or manipulation by the experimenter. In this experiment, the independent variable is the SHOES that Molly wants to test.
- Dependent variable is the measured variable that responds to the change made to the independent variable. In this case, the dependent variable is the RUNNING SPEED.
- Control variable is the variable that must be kept unchanged throughout the experiment in order not to change the experiment outcome. The control variables include; SAME RUNNING DISTANCE, SAME RUNNER (MOLLY) etc.
- Control group is the group of an experiment that does not receive the experimental treatment. In this case, it is RUNNING WITH THE REGULAR NIKE SHOES.
- Experimental group is the group that receives the experimental treatment. In this case, it is RUNNING WITH THE NEW NIKE-SPEED SHOES.

Answer:
It's a little difficult to see the difference between the finch 1 and finch 2 population lines, but their trends should match those of the food. This answer is assuming the finch 1 population aligns with the seeds line and the finch two population lines up with the fruit line: The finch 1 population has a beak adapted to eating seeds and the finch 2 population has a beak better adapted to eating fruit
Explanation:
Since we are given data for both the food source and the finch population, the answer will most likely reflect that. Therefore eliminating choices A (disease) and C (feathers). Again, this answer is assuming the finch 1 population aligns with the seeds line and the finch two population lines up with the fruit line. The lines for the finch population will match with the availability of food, so less seeds mean less finch 1 and when the amount of seeds rise up you can see the population of finch 1 also rises.

Based on this information, what is the most likely relationship between common garter snakes and rough-skinned newts?
Explanation:
In evolutionary theory, the relationship between the rough-skinned newt and the common garter snake is considered an example of co-evolution. The mutations in the snake's genes that conferred resistance to the toxin have resulted in a selective pressure that favors newts which produce more potent levels of toxin.

start fraction, 1, divided by, 10, end fraction of its value each year.
Write a function that gives the car's value, V(t)V(t)V, left parenthesis, t, right parenthesis, ttt years after it is sold.
Answer: V(t)=5000(9/10)^t
Explanation:
If the car loses 1/10 of its value each year, that means 9/10 of the value remains each year.
So each year, the car's value is multiplied by a factor of 9/10 or 0.9
If we start with the initial value, $5000 and keep multiplying by 9/10 his function gives us the car's value t years from now:
