Answer: 25.30
Step-by-step explanation:
Given : Sample size of both samples : n= 5
A pooled variance : ![S_p=40](https://tex.z-dn.net/?f=S_p%3D40)
The formula to find the standard error for the sample mean difference is given by :-
![S.E.=S_p\sqrt{\dfrac{1}{n_1}+\dfrac{1}{n_2}}\\\\\Rightarrow\ S.E.=(40)\sqrt{\dfrac{1}{5}+\dfrac{1}{5}}\\\\\Rightarrow\ S.E.=(40)\sqrt{\dfrac{2}{5}}=25.2982212813\approx25.30](https://tex.z-dn.net/?f=S.E.%3DS_p%5Csqrt%7B%5Cdfrac%7B1%7D%7Bn_1%7D%2B%5Cdfrac%7B1%7D%7Bn_2%7D%7D%5C%5C%5C%5C%5CRightarrow%5C%20S.E.%3D%2840%29%5Csqrt%7B%5Cdfrac%7B1%7D%7B5%7D%2B%5Cdfrac%7B1%7D%7B5%7D%7D%5C%5C%5C%5C%5CRightarrow%5C%20S.E.%3D%2840%29%5Csqrt%7B%5Cdfrac%7B2%7D%7B5%7D%7D%3D25.2982212813%5Capprox25.30)
Therefore, the estimated standard error for the sample mean difference is 25.30

Answer: 2x-4+x-3+2x-6=3x-11+3x-11+x-3+x-3
x=5
Step-by-step explanation:
Division by zero is not allowed in math because a that fraction is -5 parts out of 0 total parts
if you tried to divide by zero and tried to check by multiplying it out so for example
5/10=2
5=10 times 1/2
5/0=0
5=0 times (it is imposible because anything times 0 is 0)
so the answer is C
