Hi I'm back with more Solving Problems Involving Proportional Relationships because we usually do word problems; Anyways here are the questions I crave for answers so I'll be really appreciated if you answer them since they're due tomorrow!

1) There are 3 wild cards for every 54 cards in a game. If Jeanette has 72 game cards, predict how many wild cards there are in the deck.

2) In a person's body, 6 in every 24 bones are in the feet. If there are 206 bones in the body, predict how many bones are in the feet.

3) The ratio of blue balls to red balls is 6:5. There are 132 balls in all. How many blue balls are there?

Hey am have account in but wished to create an account here you guys will me with my make new friends of uk !

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
