Find the minimum sample size required to estimate the population proportion. Margin of error: 0.024; confidence level: 95%; p and q unknown?
Answer:
1667
Step-by-step explanation:
(Margin of Error)² = (z × 0.5)²/n
Where n = number of samples
Minimum number of samples formula = (z × 0.5)²/ (Margin of Error)²
From the above question:
Margin of Error = 0.024
z = z score of a 95% confidence interval = 1.96
Minimum number of samples
= (1.96 × 0.5)²/(0.024)²
= 0.9604/(0.024)²
= 1667.3611111
Approximately to the nearest whole number = 1667
Therefore, the minimum number of samples is 1667

Answer:
<KNM = 131
Step-by-step explanation:
<KNM + <MNJ= 180 so,
8x - 5 + 4x - 19 = 180-----> collect like terms----> 12x - 24 =180-----> add 24 on each side----> cancels out on the left-----> 12x = 204-----> divide by 12 on each side-----> x = 17------> plug in-----> < KNM = 8(17)-5 ---> <KNM = 131

Which number is a counterexample to the following statement? All numbers that are divisible by 2 are divisible by 4.
A. 0
B. 12
C. 28
D. 42
Using divisibility concepts, a counterexample to the statement is given by option the number 42, option D.
-------------
If the remainder of the division of A by B is 0, it is said that A is divisible by B.-------------
In option A, 0 is divisible by both 2(0/2 = 0) and 4(0/4 = 0), so it is not a counterexample.In option B, 12 is divisible by both 2(12/2 = 6) and 4(12/4 = 3), so it is not a counterexample.In option C, 28 is divisible both by 2(28/2 = 14) and 4(14/2 = 7), so it is not a counterexample.In option D, 42 divided by 4 is 10 with a remainder of 2, thus 42 is not divisible by 4, being a counterexample to the statement.A similar problem is given at https://brainly.com/question/24354438

1) 18x - 6x + 2x = 14x
Combine like terms by subtracting 6 from 18 and adding 2
2) 4b - 7 - 15b + 3 = - 11b - 4
Combine like terms add 4b and - 15b ; add -7 and 3
3) 15(6-g) = 90 - 15g

Can somebody explain to me how to solve this problem? I'm confused
Step-by-step explanation:
g(x) = f(2x), so g(x) is f(x) compressed by a factor of 2.
So if the domain of f(x) is [1, 5], then the domain of g(x) is [1/2, 5/2].
Una lancha que viaja a 10 m/s pasa por debajo de un puente 3 segundos después que ha pasado un bote que viaja a 7 m/s, ¿después de cuántos metros la lancha alcanzará al bote?
Answer:
La lancha y el bote se encontrarán a 70 metros de distancia del puente.
Step-by-step explanation:
Sea el punto debajo del puente el punto de referencia y que ambas lanchas se desplazan a velocidad a continuación, las ecuaciones cinemáticas para cada embarcación son presentadas a continuación:
Bote a 7 metros por segundo
[tex]x_{A} = x_{o}+v_{A}\cdot t[/tex] (Ec. 1)
Lancha a 10 metros por segundo
[tex]x_{B} = x_{o}+v_{B}\cdot (t-3\,s)[/tex] (Ec. 2)
Donde:
[tex]x_{o}[/tex] - Posición debajo del puente, medido en metros.
[tex]x_{A}[/tex], [tex]x_{B}[/tex] - Posición final de cada embarcación, medido en metros.
[tex]v_{A}[/tex], [tex]v_{B}[/tex] - Velocidad de cada embarcación, medida en metros por segundo.
[tex]t[/tex] - Tiempo, medido en segundos.
Para determinar la posición en la que ambas embarcaciones se encuentran, se debe determinar el instante en que ocurre a partir de la siguiente condición: [tex]x_{A} = x_{B}[/tex]
Igualando (Ec. 1) y (Ec. 2) se tiene que:
[tex]v_{A}\cdot t = v_{B}\cdot (t-3\,s)[/tex]
Ahora despejamos el tiempo:
[tex]3\cdot v_{B} = (v_{B}-v_{A})\cdot t[/tex]
[tex]t = \frac{3\cdot v_{B}}{v_{B}-v_{A}}[/tex]
Si sabemos que [tex]v_{B} = 10\,\frac{m}{s}[/tex] y [tex]v_{A} = 7\,\frac{m}{s}[/tex], entonces:
[tex]t = \frac{3\cdot \left(10\,\frac{m}{s} \right)}{10\,\frac{m}{s}-7\,\frac{m}{s}}[/tex]
[tex]t = 10\,s[/tex]
Ahora, la posición de encuentro es: ([tex]x_{o} = 0\,m[/tex], [tex]v_{A} = 7\,\frac{m}{s}[/tex] y [tex]t = 10\,s[/tex])
[tex]x_{A} = 0\,m + \left(7\,\frac{m}{s} \right)\cdot (10\,s)[/tex]
[tex]x_{A} = 70\,m[/tex]
La lancha y el bote se encontrarán a 70 metros de distancia del puente.

What is 2 times 300=? Just kidding i know the answer but any body wanna just talk?
Answer:
Sure! XD
Step-by-step explanation:
which is the right one????
B) 13
Step-by-step explanation:
Set up the question by doing 2x + 10 + 4x + 1 = 29 since both of these sections equal KN or 29. Simplify it to 6x + 11 = 29. Subtract 11 from both sides so 6x = 18. Divided both sides by 6 so x =3. CN’s equation is 4x + 1. Plug 3 in for x to be 4(3) + 1 which is 13. Hope this helped!
Answer:
13
Step-by-step explanation:
If 29 is KN, that would mean that both expressions, since they make up KN, add up to 29.
So, you end up combining like terms and getting this:
6x+11=29
Subtract 11 from both sides
6x=18
Divide both sides by 6
x=3
and now to find out CN, simply plug 3 in for x:
4(3)+1
12+1
CN=13
If 3(y + 12) = 24, find the value of 18y.
Write the definition as a biconditional statement: Two angles are vertical angles when their sides form two pairs of opposite rays.
Answer:
Two angles are said to be vertical angles if and only if their sides form two pairs of opposite rays.
Step-by-step explanation:
A biconditional statement is one that must fulfill the two conditions of the statement for it to be true. The two required conditions in the statement are always connected by if and only if.
The required statement is: Two angles are said to be vertical angles if and only if their sides form two pairs of opposite rays
Vertical angles are equal and opposite. Therefore for the biconditional statement to be true, the angles should be vertical and their sides must form two pairs of opposite rays.
