Aflare was launched up from the ground with an initial velocity of 176 feet per second (ft/s). the height of the flare t seconds after launch is modeled by the function f(t)=−16t2+176t. how long was the flare in the air before it hit the ground?

If p(a) = 0.70 and p(b) = 0.20, then a and b are independent events if

The functions f(x) and g(x) are shown in the graph f(x)=x^2 what is g(x) ?

Two groups of students were asked how many hours they spent reading each day. the table below shows the numbers for each group: group a 1 2 1 1 3 3 2 2 3 group b 3 2 3 2 2 2 1 1 2 based on the table, which of the following is true? the interquartile range for group a students is 0.5 less than the interquartile range for group b students. the interquartile range for group a students is equal to the interquartile range for group b students. the interquartile range for group a employees is 0.5 more than to the interquartile range for group b students. the interquartile range for group a employees is 1 more than the interquartile range for group b students.
