Ana e Vitória saíram, respectivamente, dos pontos A e B, no mesmo instante, e marcaram de encontrar-se no shopping, localizado no ponto E, conforme mostra a figura a seguir. Ana gastou 16 minutos para chegar ao ponto C e 24 minutos para chegar ao shopping. Já Vitória chegou ao ponto D, após 20 minutos. Considerando que r // s e que as duas mantiveram a mesma velocidade durante todo o percurso, por quantos minutos Ana esperará Vitória chegar?

Negative 5 1/12 + negative 4 1/4 + 6 3/4

Iam at home. /: i am playing video games. translate the following statement into symbolic form.

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
