In a standard 52-card deck, half of the cards are red and half are black. The 52 cards are divided evenly into four suits; spades, hearts , diamonds, clubs. Each student has three face cards(jack, queen, king), and an ace. Each Sue also has nine cards numbered from 2 to 10.

Suppose a solitaire player has played 500 games. predict how many times a player turned over a red card as a first card.

The player can except to turn over a red card about times ?

please answer this ASAP

Astudent must have an average on five test that is greater than it equal to 80% but less than 90% to receive a final grade of b. devon's greades on the first four test were 78% 62% 91% and 80% what range if grades on the fifth test would give him a b in the course? ( assuming the highest grade is 100%)

Which expression is a perfect cube? a. x8 b. y24 c. m28 d. x64

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) ).
