Answer:
![\bar X -2s = 27.12- (2*1.13) =24.86](https://tex.z-dn.net/?f=%20%5Cbar%20X%20-2s%20%3D%2027.12-%20%282%2A1.13%29%20%3D24.86)
![\bar X +2s = 27.12+(2*1.13) =29.38](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%2B2s%20%3D%2027.12%2B%282%2A1.13%29%20%3D29.38)
So if a value is less than 24.86 would be considered significantly low and a value higher than 29.38 would be considered as significantly high.
The value for the analysis is 29.8 and as we can see 29.8>29.38 so then we can consider 29.8 as a value significantly high.
Step-by-step explanation:
For this case we have the mean given
and the deviation ![s= 1.13](https://tex.z-dn.net/?f=%20s%3D%201.13)
The Range Rule of Thumb says "that the range is about four times the standard deviation"
So then we will ave approximately most of the value within 2 deviations from the mean, so we can find the limits considered normally like this:
![\bar X -2s = 27.12- (2*1.13) =24.86](https://tex.z-dn.net/?f=%20%5Cbar%20X%20-2s%20%3D%2027.12-%20%282%2A1.13%29%20%3D24.86)
![\bar X +2s = 27.12+(2*1.13) =29.38](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%2B2s%20%3D%2027.12%2B%282%2A1.13%29%20%3D29.38)
So if a value is less than 24.86 would be considered significantly low and a value higher than 29.38 would be considered as significantly high.
The value for the analysis is 29.8 and as we can see 29.8>29.38 so then we can consider 29.8 as a value significantly high.
Answer:
- B. The slope of the line is 2. This means that Jan runs 2 laps every minute.
Step-by-step explanation:
This is a proportional relationship as the line passes through the origin.
<u>Therefore you can use one point to determine the slope, (2, 4):</u>
The slope is 2. It is a 2 laps per minute.
Correct answer choice is B
The amount of miles he drives is represented by the variable m, and the amount of days is represented by d.
The equation would be:
$25d + $0.10m
