Step-by-step explanation:
you flip it from the line, match the letters (Z woube be C, X would be A, etc.) and then writw the new coordinates
We have the slope m = (6-3)/(4-1) = 3/3 = 1;
Then, y - 3 = 1·( x - 1);
finally, y = x + 2.
There are 16 smaller triangles within the main large one. .25=1/4, so your fraction is 1/4. 1/4 of 16 is 4, because 4+4+4+4=16. So colour in 4 triangles. Hope this helps!

Answer:
![E(x)=1](https://tex.z-dn.net/?f=E%28x%29%3D1)
Step-by-step explanation:
From the question we are told that:
Sample mean 1 ![\=x_1=$9](https://tex.z-dn.net/?f=%5C%3Dx_1%3D%249)
Sample mean 1 ![\=x_2=$8](https://tex.z-dn.net/?f=%5C%3Dx_2%3D%248)
Sample standard deviation 1 ![\sigma_1 = $2](https://tex.z-dn.net/?f=%5Csigma_1%20%3D%20%242)
Sample standard deviation 1 ![\sigma_2 = $1](https://tex.z-dn.net/?f=%5Csigma_2%20%3D%20%241)
Generally the equation for Point estimate is mathematically given by
![E(x)=\=x_1-\=x_2](https://tex.z-dn.net/?f=E%28x%29%3D%5C%3Dx_1-%5C%3Dx_2)
![E(x)=9-8](https://tex.z-dn.net/?f=E%28x%29%3D9-8)
![E(x)=1](https://tex.z-dn.net/?f=E%28x%29%3D1)
