Inside the square root shouldn't be negative, so x must be negative in order to form positive number inside the root.
if x = 0, y = 0
if y = -1, y = -1
if y = -4, y = -2
if y = -9, y = -3
the points lie on the graph (0,0), (-1,-1), (-4,-2), (-9,-3)
When dealing with a pool of data, the field of study is called statistics. This refers to the study of sample data and how they correlate it with the overall trend of the population. By doing this, they use terms that can best represent the sample data. These three are the most common:
1. Mean - this is the arithmetic average of the data
Mean = (<span>8+41+25+9+22+36+24+13+25+28)/10 = 23.1
2. Mode - this is the most frequent data point that can occur. In this case, the mode is 25 because it occurred twice.
3. Median - this is the middle of the sample data arranging it from least to greatest. In this case: 8, 9, 13, 22, 24, 25, 25, 28, 36, 41. The middle number is 25. Thus, the median is 25.</span>
The distance covered by the hare and the tortoise in t seconds are 8t and 5t respectively. (Simple Speed-Distance-Time relation)
The tortoise gets a 510m headstart so at t=0 is 1490m.
The functions representing the distance of both of them from the finish line is,
F(x)=2000-8t,. for hare
G(x)=1490-5t,. for tortoise
The answer is $46.25. Here is how I found it out: I did 18.50 divided by 2 to get the cost of one can then I simply did the cost of one can (which was $9.25) times 5 to get the cost of 5 cans. And I got 46.25 so $46.25 is your answer. Hope this helped you answer the question and know how to find the answer of this kind of question in the future!
