Alice was sitting on a dock looking at a lake. She picked up a stone and threw it in the air and out toward the lake. It seemed like it was in the air for a long time. The equation that can be used to model the height of the stone (in feet) as it relates to the time in the air (in seconds) is given by h(t)=5+50t-16t^2. In order to solve for how long the stone was in the air, Alice will need to use the quadratic equation. How long was the stone in the air? Round to the nearest hundredth if not an exact answer.

Analyze the data sets below. data set a 25,25,25,26,26,26,27,28,28,29,30,31,31,32,33,33,34,35,35,35 data set b 25,25,25,26,26,26,26,27,27,27,27,28,28,29,29,30,31,31,32,34 which of the following statement are true? select all that apply. a. data set a is relatively symmetric and data set b is skewed left. b.the means of the data sets are within 3 units from eachother. c.the data sets have the same standard deviation. d.the mean of data set a is 27.95 and the mean of data set b is 30. e. the data set b has a higher standard deviation than data set a. f. the mean and median of data set a are close in value.

This is different from the first one can someone me
