Answer:
195
Step-by-step explanation:
To find the 23rd term of this sequence, we can use the arithmetic sequence formula
where,
=
term
= first term
= term position
= common difference
![a_{23}=-25+(23-1)10](https://tex.z-dn.net/?f=a_%7B23%7D%3D-25%2B%2823-1%2910)
![a_{23} =195](https://tex.z-dn.net/?f=a_%7B23%7D%20%3D195)
Answer:
5p + 10 = 5(p+2)
8p + 1p = 9p
Step-by-step explanation:
your question was confusing and you didn't specify so the first one is factored and the second is simplified.. hope it helped, brainliest please?
Answer:
(E) The z-scores of the height measurements
Step-by-step explanation:
Mean is given by
![\bar {x}=\frac{1}{n}\left(\sum _{i=1}^{n}{x_{i}}\right)=\frac{x_{1}+x_{2}+\cdots +x_{n}}{n}](https://tex.z-dn.net/?f=%5Cbar%20%7Bx%7D%3D%5Cfrac%7B1%7D%7Bn%7D%5Cleft%28%5Csum%20_%7Bi%3D1%7D%5E%7Bn%7D%7Bx_%7Bi%7D%7D%5Cright%29%3D%5Cfrac%7Bx_%7B1%7D%2Bx_%7B2%7D%2B%5Ccdots%20%2Bx_%7Bn%7D%7D%7Bn%7D)
Where,
n = Number of people
= The heights of people
When converting m to cm the mean would be
![\bar {x}=\frac{1}{n}\left(\sum _{i=1}^{n}{x_{i}}\right)\times 100](https://tex.z-dn.net/?f=%5Cbar%20%7Bx%7D%3D%5Cfrac%7B1%7D%7Bn%7D%5Cleft%28%5Csum%20_%7Bi%3D1%7D%5E%7Bn%7D%7Bx_%7Bi%7D%7D%5Cright%29%5Ctimes%20100)
So, the mean would change
The median gives us the middle data value when the data values are in ascending order.
So, the median would change
Standard deviation
![s=\sqrt{\frac{1}{N-1}\sum_{i=1}^{N}(x_i-\bar{x})^2}](https://tex.z-dn.net/?f=s%3D%5Csqrt%7B%5Cfrac%7B1%7D%7BN-1%7D%5Csum_%7Bi%3D1%7D%5E%7BN%7D%28x_i-%5Cbar%7Bx%7D%29%5E2%7D)
When converting to centimeters
![s=\sqrt{\frac{1}{N-1}\sum_{i=1}^{N}\left((x_i-\bar{x})\times 100\right)^2](https://tex.z-dn.net/?f=s%3D%5Csqrt%7B%5Cfrac%7B1%7D%7BN-1%7D%5Csum_%7Bi%3D1%7D%5E%7BN%7D%5Cleft%28%28x_i-%5Cbar%7Bx%7D%29%5Ctimes%20100%5Cright%29%5E2)
Hence, the standard deviation would change
When converting to centimeters the maximum height in meters would be the maximum height in centimeters also.
The z score is given by
![z=\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
where,
x = Data point
= Mean
= Standard deviation
When converting to centimeters
![z=\frac{(x-\mu)\times 100}{\sigma\times 100}\\\Rightarrow z=\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B%28x-%5Cmu%29%5Ctimes%20100%7D%7B%5Csigma%5Ctimes%20100%7D%5C%5C%5CRightarrow%20z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
Hence, the z score would remain the same
