Hannah has a jar filled with 150 coins made up of quarters and nickels. the total value of the coins is $28.30. let x represent the number of quarters in the jar. which equation can be used to find the number of quarters?

Write the equation in logarithmic form m^x=n

The function below is written in vertex form or intercept form. rewrite them in standard form and show your work. y = 5(x+3)^2-4

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) ).
