Nitella [24]

Answer:

False (I assume it's a true/false question)

Step-by-step explanation:

Standard deviation measures how spread out the data is.  If you add 8 to all the data values, the distribution of data moves to the right (on a graph) 8 units. The shifted data are no more and no less spread out than before.  The standard deviation does not change.

A ball is dropped from a height of 64 feet. Its height, in feet, can be modeled by the function h(t) = -167 + 64, where t is the
Oliga [24]

Answer:

Step-by-step explanation:

Known facts:

  • the ball dropped from a height of 64 feet
  • function h(t) = -16t^{2}  + 64

First question:

  • the ball hits the ground when h(t) = 0, thus we get the equation

                      -16t^{2} +64 = 0\\16t^{2} = 64\\t^{2} =4\\t = 2

     So the ball hits the ground in 2s

Second question

  • to find how long it takes the ball to fall 36 feet, we must set h(t) = 64 - 36 = 28

                      -16t^{2} +64 = 28\\16t^{2} = 36\\t = \frac{6}{4} =1.5s

      So the ball hits the ground in 1.5s

Hope that helps!
