Which equation would best solve the following problem?

maria releases a javelin 1.5 meters above the ground with an initial vertical velocity of 22 meters per second. how long will it take the javelin to hit the ground?

question 2 options:

–16t2 + 22t + 1.5 = 0

–4.9t2 + 1.5t + 22 = 0

–4.9t2 + 22t + 1.5 = 0

–4.9t2+ 22t = 1.5

What is the order of magnitude for the number of liters in a large bottle of soda served at a party

F(x)=5/6x+3 which of the following is true

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
