Answer: Maximum height = 105 feet
And, It takes 9/4 seconds to reach that point.
Step-by-step explanation:
Here the given function that shows the height of the pumpkin,
--------(1)
Where t is the time in second.
Differentiating equation (1) with respect to t,
We get,
Again differentiating above equation with respect to t,
We get,
For maximum or minimum,
At t = 9/4 , h''(t) = Negative value,
Therefore, At t = 9/4 seconds, h(t) is maximum,
And, the maximum value is,
Therefore, the maximum height of the pumpkin is 105 feet at 9/4 seconds
Answer:
The width is
Step-by-step explanation:
From the question we are told that
The population standard deviation is
The sample size is
The sample mean is
Given that the confidence level is 99% then the level of significance is mathematically represented as
=>
=>
Next we obtain the critical value of from the normal distribution table, the value is
Generally margin of error is mathematically represented as
substituting values
The width of the 99% confidence interval is mathematically evaluated as
substituting values
