Answer:
The whole picture is an <em><u>supplementary</u></em> angle, which adds up to 180°
But angles 1 and 2 are <em>adjacent</em> angles. They dont overlap each other and share the same vertex or point of the same angle.
Your answer is <em>C. Adjacent angles</em>

Answer:
Step-by-step explanation:
This is a two tailed test for comparison of two variances at 2% significance level
![n_1 = 8: n_2 =6\\s_1 =10: s_2 = 7](https://tex.z-dn.net/?f=n_1%20%3D%208%3A%20%20n_2%20%3D6%5C%5Cs_1%20%3D10%3A%20s_2%20%3D%207)
deg of freedom = 7
F statistic = ![\frac{s_1^2}{s_2^2} =\frac{100}{49} \\=2.041](https://tex.z-dn.net/?f=%5Cfrac%7Bs_1%5E2%7D%7Bs_2%5E2%7D%20%3D%5Cfrac%7B100%7D%7B49%7D%20%5C%5C%3D2.041)
p value = 0.4496
1. State the decision rule for 0.02 significance level. (Round your answer to 1 decimal place.) Reject H0 if F >10.4555
2.F=2.041
3. _Accept_________H0. There is __no significant____ in the variations of the two populations
the system has no solution.
Option C is correct.
Step-by-step explanation:
We need to solve the system of equations by substitution
![x - y = 6\,\,\,eq(1)\\x = y + 2\,\,\,eq(2)](https://tex.z-dn.net/?f=x%20-%20y%20%3D%206%5C%2C%5C%2C%5C%2Ceq%281%29%5C%5Cx%20%3D%20y%20%2B%202%5C%2C%5C%2C%5C%2Ceq%282%29)
Putting value of x from eq(2) into eq(1)
![(y+2)-y=6\\y+2-y=6\\0+2=6\\0=6-2\\0\neq4](https://tex.z-dn.net/?f=%28y%2B2%29-y%3D6%5C%5Cy%2B2-y%3D6%5C%5C0%2B2%3D6%5C%5C0%3D6-2%5C%5C0%5Cneq4)
As as 0≠4is not true, we cannot find the value of y so the system has no solution.
Option C is correct.
