On the planet Jupiter, a ball this thrown upward at a velocity at 10m/s. It's height, h(t) meters after t seconds is given by the equation h(t)=-12.5(t-0.4)^2+4.
a) what is the maximum height the ball reaches?
b) what was the height of the ball when it was released from the throwers hand?
c) how many seconds after the ball was hit and did it land on the surface of Jupiter to the nearest second?

An electronics manufacturer wants to know if customers would be interested in a detachable keyboard for their tables and if so, what the most important features would be. the manufacturer partners with an electronics store to include copies of the survey with every purchase at that store for one week. which of the following best explains why this random sample is unlikely to be a good representative sample of tablet owners' preferences for a detachable keyboard? a) one week is likely not enough time to get a large enough sample. b) most people won't bother to send in the survey, which is likely to skew the results c) there is no way to verify whether the responders to the survey actually own a tablet d) the survey is biased because it was conducted through an electronics store, not the general population

If g(x) = x+1/ x-2 and h (x) =4 - x , what is the value of ( g*h) (-3)?

{0,1,2,3,4,5,6,20,21,22,23,24,25} the distribution is considered to be: skewed the right, skewed the left, not skewed?
