Answer:
Range = 13
Mean = 8.4
Variance= 21.24
Standard deviation= 4.61
Step-by-step explanation:
2, 10, 15, 3, 13, 9, 14, 7, 2, 9
For the range
Let the set of data be arranged inn ascending order
Range= higehest value- lowest value
Range = 15-2
Range= 13
For the mean
Mean = (2+2+3+7+9+9+10+13+14+15)/10
Mean = 84/10
Mean = 8.4
For variance
Variance=((2-8.4)²+(2-8.4)²+(3-8.4)²+(7-8.4)²+(9-8.4)²+(9-8.4)²+(10-8.4)²+(13-8.4)²+(14-8.4)²+(15-8.4)²)/10
Variance= (40.96+40.96+29.16+1.96+0.36+0.36+2.56+21.16+31.36+43.56)/10
Variance= 212.4/10
Variance= 21.24
Standard deviation= √variance
Standard deviation= √21.24
Standard deviation= 4.609
Approximately = 4.61

Answer:
y'=1/x
Step-by-step explanation:
![d/dx[ ln(u) ]=\frac{1}{u} *du\\y'=\frac{1}{cx} *c\\y'=\frac{1}{x}](https://tex.z-dn.net/?f=d%2Fdx%5B%20ln%28u%29%20%5D%3D%5Cfrac%7B1%7D%7Bu%7D%20%2Adu%5C%5Cy%27%3D%5Cfrac%7B1%7D%7Bcx%7D%20%2Ac%5C%5Cy%27%3D%5Cfrac%7B1%7D%7Bx%7D)
