a diameter of 120 feet. To the nearest foot, what is the minimum length of fencing he needs to buy? If the fence costs $2.10 per foot, what will be the total cost?

Answers

Answer 1

Step-by-step explanation:

they have 122.1 of total of cost

Answer 2

Answer:

It is assumed the full circular fencing is needed.

Circumference of the circle = the length of fencing:

C = πd = 3.14*120 feet = 376.8 feet ≈ 377 feet

Total cost:

377*$2.10 = $791.70

Use the sample data and confidence level given below to complete parts​ (a) through​ (d). A drug is used to help prevent blood clots in certain patients. In clinical​ trials, among 4547 patients treated with the​ drug, 114 developed the adverse reaction of nausea. Construct a 99​% confidence interval for the proportion of adverse reactions. ​a) Find the best point estimate of the population proportion p.

Answers

Answer:

The best point estimate of the population proportion p is 0.0251.

The 99​% confidence interval for the proportion of adverse reactions is (0.0191, 0.0311).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

In clinical​ trials, among 4547 patients treated with the​ drug, 114 developed the adverse reaction of nausea.

This means that [tex]n = 4547, \pi = \frac{114}{4547} = 0.0251[/tex]

The best point estimate of the population proportion p is 0.0251.

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.0251 - 2.575\sqrt{\frac{0.0251*0.9749}{4547}} = 0.0191[/tex]

The upper limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.0251 + 2.575\sqrt{\frac{0.0251*0.9749}{4547}} = 0.0311[/tex]

The 99​% confidence interval for the proportion of adverse reactions is (0.0191, 0.0311).

What is the slope represented in the table ?

Answers

Answer:

slope:2

Step-by-step explanation:

Slope is rise/run, or change in y/change in x.

With that being said, we only need two points to solve this.

Let's take the points (0,7) and (1,9)

The formula for finding the slope from two points is m=(y2-y1)/(x2-x1).

M is the slope.

y2 would be the y-value of the second point,9. y1 would be the y-value of the first point, 7.

x2 would be the x-value of the second point, 1. x1 would be the x-value of the first point, 0.

Plugging those values in to the formula, we get m=(9-7)/(1-0)

Simplifying, we get m=2/1, which is m=2.

All we need to do is get the ? by itself in both equations.

-4 - ? = - 7

-? = -3

? = 3

? - ( -3) = 5

? + 3 = 5

? = 5 - 3

Step-by-step explanation:

Do the inverse operation of what is shown to get the answer.

First ?:

-4 - ? = -7

-7 + 4 = -?

-3 = -?

3 = ?

Second ?:

? + 3 = 5 (Two negatives in a row make a positive.)

Answer:

6x + 20 + 4x + 80 - 2x=180

6x + 4x - 2x= 180 - 80 - 20

8x = 80

x = 10

The value of x in the triangle is 10, the value of each angle are; 80, 40 , 60 respectively

How can the value of x be gotten?

The total angle can be added as

note that the total angle in the triangle is 180

[tex]6x + 4x - 2x= 180 - 80 - 20[/tex]
