The height of a model rocket in feet, h(t), as a function of time t in seconds is shown in the graph. what is the practical range for the function h(t) ? all real numbers [0, 64] [0, 4] all positive integers

answer : [0,64]

The height of a model rocket in feet, ​h(t)​, as a function of time t in seconds is shown in the graph.

Range is the y value that is the height of the model rocket in feet.

From the graph we can see that the maximum height of the graph is 64

It means the maximum height is 64 feet. Height cannot be negative.

So the height of the function is from 0 to 64

Hence the range of the function h(t) is [0, 64]

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
