Hope This Helps You ❤️A 2003 survey showed that 14 out of 250 Americans surveyed had suffered some kind of identity theft in the past 12 months. What is the lower confidence limit of the 95% confidence i terval for the population proportion of Americans who were victims of identity theft
Answer:
The lower confidence limit of the 95% confidence interval for the population proportion of Americans who were victims of identity theft is 0.0275.
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 z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
A 2003 survey showed that 14 out of 250 Americans surveyed had suffered some kind of identity theft in the past 12 months.
This means that [tex]n = 250, \pi = \frac{14}{250} = 0.056[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.056 - 1.96\sqrt{\frac{0.056*0.944}{250}} = 0.0275[/tex]
The lower confidence limit of the 95% confidence interval for the population proportion of Americans who were victims of identity theft is 0.0275.

What does each number equal (degrees)?
Answer:
I'm not sure what this will do but I hope it could help!
Each angle was found using the principles of circles.
How do relate the angle at the circumference and angle at the centre made by the same arc?The angle of the circumference is half of the angle at the centre of the circle by an arc.
AB = 78°
∠5 = 39°
Angles intercepted by the same arc are equal.
∠4 = 39°
FE= 105°
∠16 =105°
ED = 27°
∠17 =27°
CD = 42°
∠10 =21°
∠3 =21°
The angle of the semi-circle is 90°.
∠2 =90°
∠8=∠9 = (180-48)/2
∠8= 66°
∠9= 66°
∠7=90°-∠8 = 90°-66°
∠7=24°
∠17 = 180°-∠15-∠16
∠17 = 180°-48°-105°
∠17 =27°
∠6=∠15/2 = 48/2
∠6=24°
∠21 = 180°-∠7-∠16
∠21 = 180°-24°-105°
∠21 =51°
∠19 =51°
∠18 = 180°-∠17-∠6
∠18 = 180°-27°-24°
∠18 = 129°
∠20 = 129°
BC = 60°
∠1 = 60/2
∠1 =30°
∠11=180°-∠1-∠2
∠11=180°-30°-90°
∠11=60°
∠13=60°
∠12=180-∠11
∠12=180°-60°
∠12=120°
∠14=120°
∠15=48°
Hence, Each angle was found using the principles of circles.

What is Area?Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -
V = ∫∫F(x, y) dx dy
Given is to find the area of the given composite figure.
It is given to find the area of the given composite figure. We can write the area of the figure as -
Area = Area of square + Area of trapezoid + Area of rectangle
Area = {side x side} + {1/2(a + b) x h} + {L x B}
Area = {10 x 10} + {1/2(14 + 8) x 4} + {20 x 6}
Area = 100 + 44 + 120
Area = 264 square centimeter
So, it can be concluded that the area of the figure is 264 square centimeter.
Therefore, we can write the the area of the figure is 264 square centimeter.

PLEASE HELP) Use a table of values to graph the function ƒ(x) = –3|x|. Select the correct graph below.
Answer:
B
Step-by-step explanation:
To find the answer you can just input a number for x and then you should come up with a y-value.
The graph mentioned in option B is correct.
We have the the following function -
f(x) = -3 |x|
We have to select the correct graph from the given ones.
State the property Modulus.For a function f(x) = x, which is real in nature -
f(x) = |x| = [tex]\left \{ {{-x\;\;\;for\;x < 0} \atop {x\;\;\;for\;x > 0}} \right.[/tex]
We will use this modulus property to solve the graph. We can further expand the function y = -3|x| as -
f(x) = -3|x| = [tex]\left \{ {{-3(-x)\;\;\;for\;x < 0} \atop {-3x\;\;\;for\;x > 0}} \right.[/tex]
For every negative value of x -
y = f(x) = 3x = negative value in a multiple of 3.
For every positive value of x -
y = f(x) = - 3x = negative value in a multiple of 3.
Hence, the graph mentioned in option B is correct.

All sides of quadrilateral ABCD are tangent to circle P.
What is the perimeter of the quadrilateral below?
Answer:
44.4 units
Step-by-step explanation:
Recall: 2 tangents drawn from an external point from a circle are congruent
Perimeter of the quadrilateral = AB + BC + CD + AD
AB = 3.1 + 8 = 11.1
BC = 3.1 + 8 = 11.1
CD = 11.1 (given)
AD = 8 + 3.1 = 11.1
Perimeter = 11.1 + 11.1 + 11.1 + 11.1
= 44.4 units

What is Binomial distribution?Statistics frequently employs the binomial distribution as a discrete distribution. When compared to a binomial distribution, the normal distribution is continuous.
The chance for 'x' success of an investigation in 'n' trials is represented by the binomial distribution.
As per the given data in the question,
Total number of students in the class = 10
So, the ways the teacher can ask 3 students to complete the task will be,
= ¹⁰C₃ = 10!/[3! (10 - 3)!]
= (10 × 9 × 8 × 7!)/[3! × 7!]

14 divided by 2 = 7
7 is now your base since we split it apart into two right triangles.
24^2 + 7^2 = 625
625: 25^2 = 225 perfect!
25 is now your height:
25 x 14 = 350, 350 divided by 2 (x 1/2) = 175(area of triangle)
175(area of triangle) x 20(width) = 2100, around 3500 m^3
