The sampling distribution is based on the assumption that the ________ hypothesis is ________. Group of answer choices research; true null; false null; true research; confounded
Answer:
True , null
Step-by-step explanation:
Mostly the true hypothesis is the null hypothesis .
We test the true hypothesis , the null hypothesis against the claim provided which is named as alternate hypothesis.
When the false hypothesis is the null hypothesis , type II error is made.
Confounded in statistics means when the alternative explanations cannot be eliminated.But we have the alternate hypothesis in hypothesis testing.
So option 1 is correct

¿Cuáles son los procedimientos a ambos lados de la igualdad que se deben realizar para calcular el valor de la incógnita x en la siguiente ecuación? 2x+5=7
Answer:
Los procedimientos que se deben realizar para calcular la incógnita x en la ecuación 2x+5=7 son:
El 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual.El 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual.Step-by-step explanation:
Siguiendo los procedimiento descritos en la respuesta, para calcular el valor de la incógnita:
2x + 5 = 7Seguimos el primer paso: el 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual:
2x = 7 - 5Seguimos el segundo paso: el 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual:
[tex]x=\frac{7-5}{2}[/tex]Como puedes ver, así se despejaría la incógnita x y solo faltaría operar los datos en la ecuación para obtener la respuesta:
[tex]x=\frac{2}{2}[/tex][tex]x=1[/tex]El resultado que nos daría la incógnita x sería 1. Podemos probar el resultado en la ecuación original para comprobar el resultado que obtuvimos:
2x + 5 = 72 *(1) + 5 = 72 + 5 = 77 = 7Así, identificamos que los procesos realizados fueron correctos.

side angle side
just look at the angle with the red line in the corner and for the side look at the two marks in the same spot you know its right because you only need to flip it for them to look the same
Answer:
C) KL = EF
Step-by-step explanation:
Since this is a SAS problem which is short for Side Angle Side, then that means that if 2 sides and 1 angle of a triangle are congruent to 2 sides and 1 angle of another triangle, then the 2 triangles are congruent.
In the problem given, it already shows us that sides DE and JK are congruent to each other.
As well as angles K and E.
So now all we need are 2 other sides to be congruent, which would be KL and EF.
Considere as seguintes afirmações: I. O inverso de 0,2 é 5. II. O triplo de \frac{2}{5} é \frac{6}{15}. III. A metade de 0,5 é \frac{1}{4}. É(são) verdadeira(s) a(s) afirmação(ões): Apenas a I; I e III; Apenas a III; I, II e III;
Answer:
I e III
Step-by-step explanation:
Recebemos declarações na questão acima para considerar.
Declaração I. O inverso de 0,2 é 5.
Matematicamente, isso é escrito como:
1 / 0,2
0,2 = 2/10
Portanto: 1 ÷ 2/10 = 1 × 10/2
= 5
Afirmação 1 é verdadeira
Declaração II.
O triplo de 2/5 é 6/15.
Triplo de 2/5 = 2/5 + 2/5 + 2/5
= 2 + 2 + 2/5
= 6/5
= 1 1/5
Declaração II é falsa
III. A metade de 0,5 é 1/5
1/2 de 0,5
= 1/2 × 0,5 = 0,25
Convertendo em fração
= 0,25 = 25/100
= 1/4
Declaração III está correta
Portanto, as afirmações verdadeiras são I e III

given sin(theta)= 12/13 in quadrant 1 determine sec(theta) PLS HELP ASAP
Answer:
Step-by-step explanation:
in quadrant 1 cos and sec are positive.
cos(θ)=√(1-sin²θ)=√(1-(12/13)²)=√((169-144)/13²)=5/13
secθ=13/5
simplify cos(2x)/ cos(x)-sin(x)
The value of the trigonometric expression cos(2x)/ [cos(x)-sin(x)] will be cos(x) + sin(x) thus option (C) is correct.
What is a trigonometric function?The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.
The trigonometric functions found in the four quadrants, as well as their graphs, domains, and differentiation and integration, will all be understood.
As per the given,
cos(2x)/ [cos(x)-sin(x)]
Since, cosx = cos²x - sin²x
cos(2x)/ [cos(x)-sin(x)] = (cos²x - sin²x)/[cos(x)-sin(x)]
Since, A² - B² = (A + B)(A - B)
(cos²x - sin²x)/[cos(x)-sin(x)] = [cos(x)+sin(x))(cos(x)-sin(x)]/[(cos(x)-sin(x))]
⇒cos(x) + sin(x)
Hence "Trigonometric expression cos(2x)/[cos(x)-sin(x)] value will be sin(x) + cos(x)".

if f(x)=3x+5 and g(x)=x^2+1, what is the value of (g o f)(x)?
Answer:
9x²+30x+26
Step-by-step explanation:
f(x) =3x+5
g(x) =x²+1
(gof)(x) = g(f(x)) = g( 3x+5) = (3x+5)² +1 = 9x²+30x+25+1 = 9x²+30x+26

How do I find the Q1 and Q3?
0,0,1,2,2,3,4,4,4,4,5,6,6,7,7
Answer:
Q1 = 2
Q3 = 6
Step-by-step explanation:
Mathematically, we have
Q1 = (n + 1)/4 th term
where n is the number of terms
By the count, we have n as 15
Q1 = (15 + 1)/4
Q1 = 4th term
Looking at the arrangement, the 4th term is 2
For Q3
Q3 = 3(n + 1)/4 th term
n = 15
Q3 = 3 * 4 = 12th term
The 12th term is 6
So that is the 3rd quartile

Football is selling boxes of candy as a fundraiser.Ms. South ordered three small boxes and two large box fora total of $36. Chris ordered four small boxes and one large boxes for a total of $30. What is the price of each type of box?
Answer: The price of each small box is $4.8 and the price of each large box is $10.8.
Step-by-step explanation:
Let x = Price of each small box, y= price of each large box.
As per given,
3x+2y= 36 ...(i)
4x+y= 30 ...(ii)
Multiplying 2 to (ii), we get
8x+2y =60...(iii)
Subtract (i) from (iii), we get
5x= 24
x= 4.8
From (ii)
4(4.8)+y= 30
19.2+y=30
y= 10.8
Hence, the price of each small box is $4.8 and the price of each large box is $10.8.
