Answer:
Step-by-step explanation:
<u>The equation for the speed is:</u>
From the equation we see for the same t the speed is greater if d is greater.
We can show that if add a vertical line to a graph and compare the d- values of the intersection of the vertical line with the graphs of the cars.
It obvious the graph of the Car B will have a greater d- value.
It means that Car B has a greater speed so it is faster that Car A.
How you do this is using the formula speed = distance/time. So this is 100/5 which is 20 meters a second. Using the conversion factor (can google "20 meters per second is how many mile") 20 meters a second = 44.7 miles per hour.
In conclusion, the answer you're looking for is D. 44.7 miles per hour.
Answer:
b. To increase the accuracy of the research and prevent skewness in the idea.
Step-by-step explanation:
Random assignment ensures that any difference between groups recorded at the end of an experiment can be attributed to the experimental procedures. It refers to how you arrange the participants into required groups (different treatment and control groups). In the case of non-random assignment, the two major problems are generalisation of results and bias, which could lead to skewness in the idea of the experiment.
One of the importance of random assignment in this given experiment is to increase the accuracy of the research and prevent skewness in the idea.
Lol that’s why not I just got to tell
