Answer:
0.0101 < p < 0.1499
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].
Out of 100 adult residents sampled, 8 had kids. Based on this, construct a 99%.
This means that [tex]n = 100, \pi = \frac{8}{100} = 0.08[/tex]
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}} = 0.08 - 2.575\sqrt{\frac{0.08*0.92}{100}} = 0.0101[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.08 + 2.575\sqrt{\frac{0.08*0.92}{100}} = 0.1499[/tex]
Express your answer in tri-inequality form.
0.0101 < p < 0.1499
The Marching Band ordered 14 pizzas for a party. Each pizza had 6 slices. Juan ate 7 of the slices. How many slices were left for the rest of the band?
Answer:
77 slices
Step-by-step explanation:
Given
[tex]Pizza=14[/tex]
[tex]Slice = 6[/tex] per pizza
[tex]Juan = 7\ slices[/tex]
Required
Determine the slices left
First, calculate the slices in 14 pizzas.
[tex]Total = 14 * 6[/tex]
[tex]Total = 84[/tex]
Subtract the amount eaten by Juan, to get the remaining.
[tex]Remaining = Total - Juan[/tex]
[tex]Remaining = 84 - 7[/tex]
[tex]Remaining = 77[/tex]

Answer:
The area is 266
Step-by-step explanation:
If the length is 19 and the width is 5 less then the width is 14. To calculate the area you need to multiply the area by the length. So the answer is 266

the area of the base is 34 cm2 the height is 7cm what is the volume
Answer:
[tex]238cm^3[/tex]
Step-by-step explanation:
The equation for volume is length x width x height
The equation for area is length x width
Since the area of the base is known, we can substitute that into the volume equation
base x height
34 x 7 = 238 cm^3
Use elimination to solve the following system of
equations: 17x - 2y = 25
17x + 3y = 5
Step-by-step explanation:
[tex]17x - 2y = 25[/tex]
[tex]17x + 3y = 5[/tex]
Both equations have a [tex]17x[/tex] term in them, so if we subtract the second equation from the first, it will eliminate those terms, allowing us to solve for the remaining [tex]y[/tex] terms:
[tex](17x - 2y) - (17x + 3y) = 25 - 5[/tex]
[tex](17x - 17x) + (-2y - 3y) = 20[/tex]
[tex]-5y = 20[/tex]
[tex]y = -4[/tex]
Finally, we can plug this value for [tex]y[/tex] into either of the two original equations to solve for [tex]x[/tex]:
[tex]17x - 2(-4) = 25[/tex]
[tex]17x + 8 = 25[/tex]
[tex]17x = 17[/tex]
[tex]x = 1[/tex]
This means the solution to the system of equations is [tex](1, -4)[/tex].

For a car moving at a constant speed, the distance traveled varies directly with the time spent driving. If such a car travels 390 miles in 6 hours, how many
miles does it travel in 5 hours?
Answer:
325 miles
Step-by-step explanation:
Given that,
A car travels 390 miles in 6 hours.
We need to find the distance travelled in 5 hours.
6 hours = 390 miles
1 hour = 65 miles
In 5 hours,
5 hours = (65×5) miles
= 325 miles
So, it will travel 325 miles in 5 hours.

Answer:
7 feet
Step-by-step explanation:
Answer:
A. 4ft
Step-by-step explanation:
It would be four feet because since the opening is 3ft and the length is 5ft, it would be 4ft because the length is going to be close to the height which would also be the same with the opening. The opening is always a little shorter than the top of the tent meaning this would be 4ft.

Suppose a test has six multiple-choice questions with four options and eight true/false questions. If a person responds to all questions, in how many ways can the 14 questions be answered?
Answer:
1,360
Step-by-step explanation:
Ok, so for the first 6 questions, if each one can be answered 4 different times, that would mean that it would be 6 to the 4th power (or 6 x 6 x 6 x 6)
That would be 1296.
Then, we have the other 8 questions, that can be answered 2 different ways. That would be represented as 8 to the second power (or 8 x 8)
That would be 64.
Now, we have to add the two numbers together to get the total. 1296+64 = 1,360
That's how you get the answer! I hope this is correct!

Express the function graphed on the axes below as a piecewise function.
1. Complete the empty cells in the table below with the correct values. sin theta= sqrt 2/2
Using trigonometric function concepts, it is found that:
The angle is of 45 degrees, or [tex]\frac{\pi}{4}[/tex] radians.[tex]\cos{\theta} = \frac{\sqrt{2}}{2}[/tex][tex]\csc{\theta} = \sqrt{2}[/tex][tex]\sec{\theta} = \sqrt{2}[/tex][tex]\cot{\theta} = 1[/tex]From the sine, we have that:
[tex]\sin{\theta} = \frac{\sqrt{2}}{2}[/tex]
Then:
[tex]\sin^{-1}{\sin{\theta}} = \sin^{-1}{\frac{\sqrt{2}}{2}}[/tex]
[tex]\theta = \frac{\pi}{4}[/tex]
Since pi radians is 180º, this angle is of 180/4 = 45 degrees.
From the tangent:
[tex]\tan{\theta} = \frac{\sin{\theta}}{\cos{\theta}}[/tex]
[tex]1 = \frac{\frac{\sqrt{2}}{2}}{\cos{\theta}}[/tex]
[tex]\cos{\theta} = \frac{\sqrt{2}}{2}[/tex]
[tex]\cot{\theta} = \frac{1}{\tan{\theta}}[/tex]
[tex]\cot{\theta} = 1[/tex]
For the cosecant and secant:
[tex]\csc{\theta} = \frac{1}{\sin{\theta}} = \frac{1}{\frac{\sqrt{2}}{2}} = \frac{2}{\sqrt{2}} \times \frac{\sqrt{2}}{\sqrt{2}} = \sqrt{2}[/tex]
[tex]\sec{\theta} = \frac{1}{\cos{\theta}} = \frac{1}{\frac{\sqrt{2}}{2}} = \frac{2}{\sqrt{2}} \times \frac{\sqrt{2}}{\sqrt{2}} = \sqrt{2}[/tex]
[tex]\csc{\theta} = \sqrt{2}[/tex]
[tex]\sec{\theta} = \sqrt{2}[/tex]

3.96
Step-by-step explanation:
Aminah increased the price of the book to [tex]8\cdot1.2=9.6[/tex]. James increased the price of the book to [tex]9.6\cdot1.15=11.04[/tex]. So James needs to give [tex]15-11.04=3.96[/tex] to Khalid.

Answer:
A. 7
Step-by-step explanation:
No.of unique roots are possible in a seventh-degree polynomial is 7
State fundamental theorem of AlgebraA polynomial of degree n can have at most n real roots. The Degree of Polynomial with one variable is largest power of that variable.For example, 3x^2+4x+2 = 0 have two roots since the equation degree 2.A real number p is a zero of a polynomial f(x),f(p) = 0.
Since seventh degree polynomial has degree 7, number of roots in a seventh-degree polynomial is 7.
Therefore, the number of unique roots are possible in a seventh-degree polynomial is 7.

Answer:
P(A or B) = 0.75
Step-by-step explanation:
For Venn probabilities, we have that:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
In which [tex]P(A \cup B)[/tex] is P(A or B).
We have that:
[tex]P(A) = 0.62, P(B) = 0.25, P(A \cap B) = 0.12[/tex]
So
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.62 + 0.25 - 0.12 = 0.75[/tex]
P(A or B) = 0.75
