The first task in such exercises is to order the data in ascending order.
201,218, 242, 257, 265, 275, 301.
The algorithm to find the first quartile of a distribution of discrete observations is: If the number of observations is odd;
Exclude the median. Then, the first quartile is the median of the lower half of the observations.
If the number of observations is even, take the median of the lower half of observations immediately.
Here, we have 7 observations. The median is 257 and the observations below it are 201,218,242. The median of this is 218. Thus, 218 is the first quartile. (Similarly, 275 is the 3rd quartile).
Answer:
80
Step-by-step explanation:
<u>let the number be x:</u>
1)
then x * 15% = 48
x = 48 / 15%
x = 320
2)
then x * 40% = 128
x = 128 / 40%
x = 320
<em>So confirmed that the number is 320.</em>
- the number is 320, so 25% of it,
320 * 25% = 80
So, 25% of that 320 is 80. and that's out final answer
Answer:
About 10 feet
Step-by-step explanation:
Please see the attached image.
tan(58)=x/6
x=tan(58)*6≈10
Answer:
The graph I expect to have a negative correlation is the third graph.
Step-by-step explanation:
Positive correlation is when the the x-values increase with a corresponding increase in y-values.
Negative correlation is when the x-values increases with a corresponding decrease in y-values.
No correlation is when only x or y variable changes.
From the graphs given the only one that has a negative correlation is the third graph.
The answer is 55 yd.
You can find this by dividing the area, 4400 yd^2, by the length, 80 yd, which gets you 55 yd.
