Answer:
Without the answers provided with the question, it would take the bus 3.85 (rounded to nearest hundredth) hours to get 30 km away from Orlando.
Step-by-step explanation:
It takes the bus approximately (when rounded to the nearest tenth) 4.3 hours to get to Orlando from Michigan hence the bus drives 70 km/h and the distance is 300 km.
You can find this by dividing 300 by 70, which equals 4.28571428571
Answer:
The width of the confidence interval decreases.
Step-by-step explanation:
In a normal distribution, if the confidence level is decreased while the sample size remains the same, the confidence interval for the population mean narrows. Since the certainty required is lower, the interval can be narrowed towards a central point, which is the calculated sample mean.
Therefore, the width of the confidence interval decreases.
The equation f(t) = -16t² + 176t is a quadratic equation, and so its maximum must be found at its vertex. In order to get this, you can use the formula
t = -b/2a.
Substituting, we have:
t = -176/2(-16) = 5.5 seconds.
But this is just only the time needed for the flare to reach its maximum height. To solve for the time the flare has been in the air, we multiply the maximum height by 2.
2 x 5.5 seconds = 11 seconds.
