A national opinion poll found that 52% of all American adults agree that parents should be given vouchers
that are good for education at any public or private school of their choice. How large of a sample would be
required to be within 3 percentage points with 95% confidence?
According to the information given, using the z-distribution, it is found that a sample of 1066 is needed.
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]\alpha[/tex], we have the following confidence interval of proportions, according to the z-distribution.
[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]\frac{1+\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In this problem, the estimate is of 52%, hence [tex]\pi = 0.52[/tex].
95% confidence level
So [tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].
The minimum sample size is n for which M = 0.03, hence:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 1.96\sqrt{\frac{0.52(0.48)}{n}}[/tex]
[tex]0.03\sqrt{n} = 1.96\sqrt{0.52(0.48)}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.52(0.48)}}{0.03}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.52(0.48)}}{0.03})^2[/tex]
[tex]n = 1065.4[/tex]
Rounding up, a sample of 1066 is needed.

For 6 I’ve already done it I just need assistance and see if I did it correctly
Answer:
Step-by-step explanation:
6)For question 6 you have the right idea but as the new image is bigger than the pre-image the scale factor would be 3/1
7)You have the right answer but the fraction can be simplified to 2
8)I think this question is asking for the angle in the triangle on the left that is the same as the one on the right so from left to right,
F=R G=S H=T
FG=RS GH=ST FH=RT
9)The scale facto for the longest edge here is 2 but the scale factor for the shortest edge is 18/8 which is equal to 9/4 so the are not congruent as they have two different scale factors. Answer) no
10) the triangles are similar as angle a=n and 55+35+90 = 180 so yes they are similar

Step-by-step explanation:
Answer:
Not sure
Step-by-step explanation:
a) let p,q and r be propositions. Simplify the following compound proposition: ((¬ r)∧p∧q)∨((¬ r)∧(¬ p)∧q).
b) Using two different methods determine whether the propositions (p⟶q)⟶q and p∨q are logically equivalent.
a) Starting with
(¬r ∧ p ∧ q) ∨ (¬r ∧ ¬p ∧ q)
distribute the disjunction (∨) :
((¬r ∧ p ∧ q) ∨ ¬r) ∧ ((¬r ∧ p ∧ q) ∨ ¬p) ∧ ((¬r ∧ p ∧ q) ∨ q)
and once more among the grouped statements:
(¬r ∧ p ∧ q) ∨ ¬r ≡ (¬r ∨ ¬r) ∧ (p ∨ ¬r) ∧ (q ∨ ¬r)
(¬r ∧ p ∧ q) ∨ ¬p ≡ (¬r ∨ ¬p) ∧ (p ∨ ¬p) ∧ (q ∨ ¬p)
(¬r ∧ p ∧ q) ∨ ¬p ≡ (¬r ∨ q) ∧ (p ∨ q) ∧ (q ∨ q)
So, the original statement is equivalent to
[(¬r ∨ ¬r) ∧ (p ∨ ¬r) ∧ (q ∨ ¬r)] ∧ [(¬r ∨ ¬p) ∧ (p ∨ ¬p) ∧ (q ∨ ¬p)] ∧ [(¬r ∨ q) ∧ (p ∨ q) ∧ (q ∨ q)]
which reduces to
[¬r ∧ (p ∨ ¬r) ∧ (q ∨ ¬r)] ∧ [(¬r ∨ ¬p) ∧ (q ∨ ¬p)] ∧ [(¬r ∨ q) ∧ (p ∨ q) ∧ q]
and further to
¬r ∧ (p ∨ ¬r) ∧ (¬r ∨ ¬p) ∧ (q ∨ ¬p) ∧ (p ∨ q) ∧ q
For any statements X and Y, we have the identity
• X ≡ (X ∨ Y) ∧ (X ∨ ¬Y)
so another step of simplification reduces the underlined expressions to
¬r ∧ ¬r ∧ q ∧ q
which leaves us with
¬r ∧ q
###
b) Recall the identity,
p ⇒ q ≡ ¬p ∨ q
Then
(p ⇒ q) ⇒ q ≡ (¬p ∨ q) ⇒ q ≡ ¬(¬p ∨ q) ∨ q
Distributing the negation gives
(p ⇒ q) ⇒ q ≡ (p ∧ ¬q) ∨ q
and distributing the disjunction gives
(p ⇒ q) ⇒ q ≡ (p ∨ q) ∧ (¬q ∨ q)
from which it follows that
(p ⇒ q) ⇒ q ≡ p ∨ q

In this problem, we will look into the geometric design of the three-petal motif seen in a medieval rose window shown in the picture.
The three major arcs seen in the construction image 1 are congruent. The direct distance between E and J (Chord length EJ) is 193 cm and the depth of each arc (length of LK shown in construction image 2) is 147 cm.
what is the total area?
The total area of the three-petal motif is [tex]93937cm^2[/tex]
The three petal motif has the structure shown in the accompanying image. the dark gray area is the equilateral triangle. The light gray areas are the major segments of each of the circles.
The area of the three-petal motif, then, is the sum of the area of the equilateral triangle and the three major segments (all of which have the same area)
From the second image
Area of equilateral triangle = [tex]16129cm^2[/tex]
Area of each major segment = [tex]25936cm^2[/tex]
Therefore,
Area of three-petal motif = [tex]16129cm^2+3(25936cm^2)=93937cm^2[/tex]

The value of x is found to be -4.
What is a function?A function y = f(x) is a one to one relation between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
Given function is as below,
f(x) = 4x + 11 (1)
And, f(x) = -1
Substitute the value of f(x) in equation (1) to obtain,
-1 = 4x + 11
