30/5 = 6
your answer is 6
hope this helps
The period is 2.
Normally the period of sin(x) is 2pi, but the pi inside the sin(pix) is a horizontal compression by a factor of 1/pi. So 2pi·1/pi = 2
The "1/2" and "+3" do not impact the period. Those just impact the amplitude (vertical aspect) of the graph.
Answer:
95%
Step-by-step explanation:
The z-scores associated with the limits are ...
z = (x -μ)/σ
z = ({80, 108} -94)/7 = {-14, 14}/7 = {-2, 2}
That is, we're interested in flight times that lie within 2 standard deviations of the mean. The empirical rule tells us that 95% of the distribution lies within 2 standard deviations of the mean.
The area equals 82.5
The perimeter equals 38.6
