Answer:
There will be sufficient evidence to conclude. A further explanation is provided below.
Step-by-step explanation:
The given values are:
[tex]\sigma=1.8[/tex]
[tex]\alpha=0.05[/tex]
[tex]n=10[/tex]
As we know,
[tex]\bar{x}=\frac{\Sigma x_i}{n}[/tex]
[tex]=\frac{71.5}{10}[/tex]
[tex]=7.15[/tex]
The standard deviation will be:
⇒ [tex]s=\sqrt{\frac{1}{n-1} \Sigma(x_i- \bar{x})^2 }[/tex]
On substituting the values, we get
⇒ [tex]=\sqrt{\frac{1}{10-1} [(6.5-7.15)^2+...(7.7-7.15)^2]}[/tex]
⇒ [tex]=\sqrt{\frac{1}{9} [(6.5-7.15)^2+...(7.7-7.15)^2]}[/tex]
⇒ [tex]=0.477[/tex]
According to the question,
Hypotheses:
[tex]H_o: \sigma=1.8[/tex]
[tex]H_a: \sigma<1.8[/tex]
The test statistic will be:
⇒ [tex]X^2=\frac{(n-1)s^2}{\sigma^2}[/tex]
⇒ [tex]=\frac{(10-1)\times 0.477^2}{1.8^2}[/tex]
⇒ [tex]=\frac{2.0477}{3.24}[/tex]
⇒ [tex]=0.632[/tex]
Thus the above is the correct response.

finding angle measures with trig. Find the missing angle measures. Round to the nearest whole number
Step-by-step explanation:
let angle be x
Step-by-step explanation:
relationship between perpendicular and hypotenuse is given by sin angle
sin x =p/h
sin x=13/26
x=sin-¹(13/26)=30°
2.relationship between perpendicular and base is given by tan angle
tan x =p/b
tan x =7/16
x=tan -¹(7/16)=23.63°
3.relationship between between perpendicular and base is given by tan angle
tan x =p/b
tanx=31/50
x=tan-¹(31/50)=31.8°
4.relationship between base and hypotenuse is given by cos angle
cos x =b/h
cos x=5/7
x=cos-1(5/7)=44.4°
5.relationship between perpendicular and hypotenuse is given by sin angle
sin x =p/h
sin x=4/14
x=sin-¹(4/14)=16.6
6..relationship between base and hypotenuse is given by cos angle
cos x=6/7
x=cos-¹(6/7)=31.0027
7.relationship between perpendicular and base is given by tan angle
.tanx=29/37
x=tan-¹(29/37)=38.09
8.relationship between perpendicular and hypotenuse is given by sin angle

Im not sure how to do this or what function to use SIN, COS, or TAN but if you could walk me through it that would be so so so amazing!!! Thanks so much have an amazing day!!!
Answer: 3.8
Step-by-step explanation:first, you need to figure out what side you’re looking for. Side AC is opposite of the angle you’re given. They also give you length of side AB which is 4. That is the hypotenuse (side directly across from right angle). So, you have the hypotenuse, and need the find the opposite side measure. Which option uses opposite and hypotenuse? That’s Sin. So, you would do: sin70 = ? / 4.
sin (of given angle)= opposite / hypotenuse.
Sin (70 degrees) = ? / 4
Then you solve for “?”
Type sin70 into your calculator, then multiply both sides by 4 to get “?” by itself. You should get 3.758770483, which rounds to 3.8
Miguel compró 253 Kilos de pescado para venderlo en su negocio, si decide vender cada kilo de pescado en Bs 1.900.000. Entonces, ¿Cuánto dinero recaudó en total por la venta del pescado?
Answer:
Miguel recaudó Bs 480.700.000 por la venta del pescado.
Step-by-step explanation:
Con la información proporcionada puedes calcular el dinero que recaudó en total por la venta del pescado multiplicando el precio de venta de cada kilo de pescado por el número de kilos que Miguel compró:
Número de kilos comprados=253
Precio de venta por kilo=1.900.000
Total vendido=253*1.900.000
Total vendido=480.700.000
De acuerdo a esto, la respuesta es que Miguel recaudó Bs 480.700.000 por la venta del pescado.

the surface area of a cube is 600 cm. what is its volume? 200 1000 600 800
Answer:
1000 cm^3
Step-by-step explanation:
First, Find the side length of the cube. The surface area is all the area on the surface of a 3-dimensional object. Since a square has 6 congruent faces the formula for surface area is 6s^2 where s is the side length. Since we know the surface area we can solve for the side length.
600=6s^2- DIvide by 6
100=s^2- Take the square root of both sides.
10=s
The volume of a cube is s^3.
10^3=V
1000=V

The difference between two numbers is 3. The sum of the same tow numbers is 13. What is the
product of the two numbers?
Answer: 40
Step-by-step explanation:
Let the two numbers be a and b.
Therefore,
a - b = 3 ....... i
a + b = 13 ....... ii
From equation I, a = 3 + b
Put a = 3+b into equation ii
a + b = 13
3 + b + b = 13
3 + 2b = 13
2b = 13 - 3
2b = 10
b = 10/2
b = 5
Since a = 3 + b
a = 3 + 5
a = 8
The product of the numbers will be:
= 8 × 5
= 40

Question: pentagon STUVW is similar to S' T' U' V' W'. angle U=56 degrees, angle U' = 3x-16, and Angle T'=x+46. ST=57, UV=63, S' T'=19 and U' V' =y+4
a. Find x
b. find angle T'
c. Find y
you have to do, a, b, and c
Answer:
Similarity doesn't changes angle measures
∠U = 56°, ∠U' = 3x - 16∠U = ∠U'a) 3x - 16 = 56 ⇒ 3x = 72 ⇒ x = 24°
b) ∠T = x + 46 = 24 + 46 = 70°
c) Scale factor:
k = S'T'/ST = 19/57 = 1/3Find y using known sides and scale factor:
U'V'/UV = 1/3(y + 4)/63 = 1/3y + 4 = 21y = 21 - 4y = 17What’s the answer to this question?

En la tienda de don chuy vender tres cajas de colores de 36 piezas en $258,en cambio en la papeleria de la ciudad encontramos 5 piesas delos colores en$440
Responder:
Tienda de la ciudad
Explicación paso a paso:
Para obtener el precio unitario por caja:
Importe pagado / número de cajas.
Para cajas de 3 colores:
$ 258/2 = $ 129
Para las cajas de color /:
$ 440/5 = $ 88
$ 88 <$ 129
Por lo tanto, las cajas de colores son más baratas en la tienda de la ciudad.
