Step-by-step explanation:
Use formula to find the slope/gradient
(-5, -1) = (x1, y1)
(5, 11) = (x2, y2)
So,

Answer:
5571.99
Step-by-step explanation:
We need to use the Pythagorean theorem to solve the problem.
The theorem indicates that,
Once this is defined, we proceed to define the volume of a cone,
Substituting,
We need to find the maximum height, so we proceed to calculate h, by means of its derivative and equalizing 0,
then
<em>We select the positiv value.</em>
We have then,
We can now calculate the maximum volume,
Answer:
a
The 95% confidence bounds is
b
It was not necessary to make any assumption about the shape of the travel time distribution
Step-by-step explanation:
From the question we are told that
The sample size is n = 30
The sample mean is
The standard deviation is
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of is
Generally the margin of error is mathematically represented as
=>
=>
Generally 95% confidence bounds is mathematically represented as
=>
=>
This 95% confidence bounds show that there is 95% confidence that the true mean lies within this bound hence there is it was not necessary to make any assumption about the shape of the travel time distribution
