Answer:
C. The given value is a statistic for the yearyear because the data collected represent a samplesample.
Explanation:
A parameter is a numerical measurement of a population while a statistic is a numerical measurement of a sample. Statistics use assumptions to represent relations among variables and parameters should meet requirements and present more objective data. In this case, the voltage value found is the mean of a 34 days sample and, therefore, the given value is a statistic of the daily voltage for the year.
Answer:
144 ft
Explanation:
h(t) = -16t² + 64t + 80
The maximum height is at the vertex. We can find the vertex of a parabola using -b / (2a):
t = -64 / (2×-16)
t = 2
The vertex is at 2 seconds. The height of the stone at this time is:
h(2) = -16(2)² + 64(2) + 80
h(2) = 144
The maximum height is 144 feet.
