Asap will give brainliest +60 points

two airplanes leave the airport. plane a departs at a 42° angle from the runway, and plane b departs at a 44° from the runway. which plane was farther away from the airport when it was 7 miles from the ground? round the solutions to the nearest hundredth.

plane a because it was 9.428 miles away
plane a because it was 10.46 miles away
plane b because it was 10.08 miles away
plane b because it was 9.73 miles away

Can someone me with my math problems i have a bunch. i will give brainliest and lots of pleeeaaasssee

|z| > (1/2) {-1/2, 1/2} {z|(-1/2) < z < (1/2)} {z|z < (-1/2) ∪ z > (1/2)}

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) ).
