What is the next step in the proof? choose the most logical approach.
a.
statement: 26* 214
reason: for parallel lines cut by a transversal, corresponding angles are congruent.
o b.
statement: 26 = 27
reason: vertical angles theorem
o
c.
statement: 26 and 25 are supplementary.
reason: linear pair theorem
d.
statement: m26 + m28 = 180°
reason: angle addition

Me. i can't figure out this question. give an explanation too. .

Select all the correct locations on the table. consider the following expression. 76.493 select "equivalent" or "not equivalent" to indicate whether the expression above is equivalent or not equivalent to the values or expressions in the last column equivalent not equivalent 343 equivalent not equivalent 49 78.498 78.498 75.493 equivalent not equivalent 75.7 equivalent not equivalent

Consider the linear model for a two-stage nested design with b nested in a as given below. yijk=\small \mu + \small \taui + \small \betaj(i) + \small \varepsilon(ij)k , for i=1,; j= ; k=1, assumption: \small \varepsilon(ij)k ~ iid n (0, \small \sigma2) ; \small \taui ~ iid n(0, \small \sigmat2 ); \tiny \sum_{j=1}^{b} \small \betaj(i) =0; \small \varepsilon(ij)k and \small \taui are independent. using only the given information, derive the least square estimator of \small \betaj(i) using the appropriate constraints (sum to zero constraints) and derive e(msb(a) ).
