Answer:
The datapoint 9.0 ppm is outlier at the 90% confidence level.
Explanation:
The old data has following values
mean=10.5 mm
standard deviation 0.2 mm
Now the mean of new values is calculated as following
![mean=\frac{10+10.4+10.2+10.8+10.1+10.5+10.1}{7}\\mean=10.3 ppm](https://tex.z-dn.net/?f=mean%3D%5Cfrac%7B10%2B10.4%2B10.2%2B10.8%2B10.1%2B10.5%2B10.1%7D%7B7%7D%5C%5Cmean%3D10.3%20ppm)
So the value as 9.0 ppm can be considered easily as outlier in this regard.

good because piggy loves peppa pig :3
Explanation:
In the process of peppering the question with those forty (40 !) un-necessary quotation marks, you neglected to actually show us the illustration. So we have no information to describe the adjacent positions, and we're not able to come up with any answer to the question.
I cant really say but i believe it is called extinction
The deceleration of the rocket sled if it comes to rest in 1.1 s from a speed of 1000 km/h is
.
The acceleration in opposite direction is known as the deceleration. Basically the deceleration is negative value of the acceleration since the negative sign depicts its opposite in direction.
The given data:
time, t = 1.1 s
initial speed, u = 1000 km/h = ![\frac{2500}{9}\ m/s](https://tex.z-dn.net/?f=%5Cfrac%7B2500%7D%7B9%7D%5C%20m%2Fs)
final speed, v = 0 m/s
So we will be using the equation of motion, that is,
v = u + at
![\therefore 0=\frac{2500}{9} + a(1.1)](https://tex.z-dn.net/?f=%5Ctherefore%200%3D%5Cfrac%7B2500%7D%7B9%7D%20%2B%20a%281.1%29)
![\Rightarrow a=-\frac{2500}{9(1.1)}](https://tex.z-dn.net/?f=%5CRightarrow%20a%3D-%5Cfrac%7B2500%7D%7B9%281.1%29%7D)
![\therefore a = - 252.52 \ m/s^2](https://tex.z-dn.net/?f=%5Ctherefore%20a%20%3D%20-%20252.52%20%5C%20m%2Fs%5E2)
Hence , the deceleration of the rocket is
.
