Answer:

If Steve drives for 812 hours at 72 miles per hour, he drives 58,464 miles in total.(Side Note: if you mean 8 1/2 hours then it's 612 miles

Step-by-step explanation:

To find distance dealing with time and speed, we can use the formula d=rt.

D= Distance

R= Speed

T= Time

Now we plug in our values! D=72 × 812 and we get D= 58,464 miles or if you meant 8 1/2 hours, then it's 612 miles

Hope this helps! :)

What is the volume of the cone with radius 3 ft and height 5 ft? Express the answer in terms of π.
I am Lyosha [343]

Answer:

V = 15 pi ft^3

Step-by-step explanation:

The volume of a cone is given by the formula

V=1/3 pi r^2 h

We know the radius and the height

V = 1/3 pi *(3)^2*5

V = 1/3 *pi*9*5

V = 15 * pi

Leave in terms of pi

V = 15 pi ft^3

52% of 1000 registered voters intend to vote for Steven Collins for mayor. Based on a 95% confidence interval, can we assume tha
Naya [18.7K]

Using the z-distribution, it is found that the correct option regarding the question in the problem is given by:

B. No, since the confidence interval includes values less than 50%, his opponent may get more votes.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which:

  • \pi is the sample proportion.
  • z is the critical value.
  • n is the sample size.

In this problem, we have a 95% confidence level, hence\alpha = 0.95, z is the value of Z that has a p-value of \frac{1+0.95}{2} = 0.975, so the critical value is z = 1.96.

In this problem, the parameters are given as follows:

\pi = 0.52, n = 1000

Hence, the bounds are given by:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.52 - 1.96\sqrt{\frac{0.52(0.48)}{1000}} = 0.489

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.52 + 1.96\sqrt{\frac{0.52(0.48)}{1000}} = 0.551

The lower bound is below 0.5, hence option B is correct.
