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>
Answer:
How far does Clare travel in one hour?
A: 36
How far does Clare travel in three hours?
A: 108
How far does Clare travel in 3.5 hours?
A: 126
Step-by-step explanation:
Find the Unit Value
72/2 = 36
Clare travels 36 miles per hour
Therefore, you must multiply the hours by the Unit travel time for the answers.
1 X 36 = 36
3 X 36 = 108
3.5 X 36 = 126
Answer:
The first box in the girl row is 18, the second one in the boy row is 8, and the bottom one is also 18.
Step-by-step explanation:
To get 81 to 9, you have to divide by 9, which means you have to do the same to 72. You get the ration 9 to 8, 9 being girls and 8 being guys. Then to get from 8 guys to 16, you have to multiply by 2, which means you do the same to 9 and get the answer of 18 girls. Hope this helps :)
Answer:
y+20 = 9(x+2)
Step-by-step explanation:
The slope that passes through the points is
m = (y2-y1)/(x2-x1)
= (79- -20)/ (9--2)
= (79+20)/(9+2)
= 99/11
= 9
We can use point slope form to write an equation. It says to use the first point.
y-y1 = m(x-x1)
y--20 = 9(x--2)
y+20 = 9(x+2)
9.35 times 10 to the second power
