SHOW YOUR WORK AS MUCH AS POSSIBLE 60 POINTS A checking account is setup with an initial balance of $3,600 and $400 is removed from the count each month for rent no other transactions occur on the account

a. create an expression representing the amount in her account

b. write an equation whose solution is the number of months M it takes for the account balance to reach $2,000

c. what does each part of your equation represent

Which pair of numbers is relatively prime? a. 105 and 128 b. 130 and 273 c. 205 and 350 d. 273 and 333

Which angle is the smallest? also give me an explanation so i can complete it to other questions as well, : )

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) ).
