Kat is interested in getting chickens so she can have fresh eggs. Before she buys her chickens, she wants to find the mean number of eggs each one will lay. She begins by randomly selecting 40 chickens from a large poultry farm and counts how many eggs each one lays within one month. She finds the mean to be 24.8 eggs with a standard deviation of 6.9 eggs. The resulting interval is (22.96, 26.64). Which of the following correctly interprets the 90% confidence interval for the true mean number of eggs chickens from this poultry farm lay within one month?
90% of all chickens at this farm lay between 22.96 and 26.64 eggs.
In repeated sampling, 90% of the time the true mean number of eggs chickens at this farm lay is 24.8.
Kat can be 90% confident that the constructed interval (22.96, 26.64) captures the true mean number of eggs chickens from this farm lay.
In repeated sampling, 90% of the time the true mean number of eggs laid by chickens from this farm will be captured within the interval (22.96, 26.64).
Answer:
C. Kat can be 90% confident that the constructed interval (22.96, 26.64) captures the true mean number of eggs chickens from this farm lay.

Calcula y comprueba las ecuaciones: plisss lo necesito alguien me puede ayudar a) 2X = 6 b) 10 + Z = 20 c) P + 9 = 11 d) 3X + 8 = + 29 e) 2U + 8 = 10
Answer:
a) x=3
b) z=10
c) P= 2
d) X=7
e) U=1
Step-by-step explanation:
Resolver una ecuación consiste en hallar los valores de la variable que hacen cierta la igualdad.
a) 2x= 6
El coeficiente es el número junto a la variable. En este caso, el coeficiente es 2. Para eliminar este número en la expresión 2x, debido a que la variable x esta multiplicada por 2, deberás dividir ambos lados de la ecuación entre 2, debido a que la operación opuesta de la multiplicación es la división.
(2x)÷2=6÷2
x= 3
Comprobar la solución de una ecuación se hace al remplazar la variable en una ecuación con el valor de la solución. La solución debería satisfacer la ecuación cuando se ingresa en esta.
En este caso:
2*3= 6
6=6
b) 10 + z= 20
En este caso se debe sumar o restar la constante que se encuentra acompañando a la variable en ambos lados de la ecuación de manera de aislar el término de la variable. En este caso:
10 - 10 + z= 20 -10
z= 10
Comprobación:
10 + z=20
10 + 10=20
20=20
c) P + 9= 11
P +9 - 9= 11 -9
P=2
Comprobación:
2 + 9= 11
11=11
d) 3X + 8 = 29
En este caso, se suma o resta la constante en ambos lados de la ecuación y luego se elimina el coeficiente de la variable mediante la división o multiplicación. Esto es:
3X + 8 - 8= 29 - 8
3X= 21
3X ÷3= 21÷3
X=7
Comprobación:
3*7 + 8=29
21+8=29
29=29
e) 2U + 8= 10
2U + 8 - 8= 10 -8
2U= 2
2U ÷2= 2÷2
U=1
Comprobación:
2*1 + 8= 10
2 + 8= 10
10=10

Consider the two points (1, 6) and (4, 48).
a. Is there a line that goes through these two points? How do you know? If there is one, what is the equation of the line going through these
Answer:
Yes there is a line
y=14x-8
Step-by-step explanation:
use slope formula and incorporate the slope into the coordinates
Answer:
[tex]y = 14x - 8[/tex]
Step-by-step explanation:
. Using euclid postulate,
" any two points can be on a line".
So yes a line can be formed
Use the linear equation in ppont-slope form
[tex]y = mx + b[/tex]
where m is slope, b is the y intercept.
We can find the slope of the points first.
[tex]48 - 6 = 42[/tex]
[tex]4 - 1 = 3[/tex]
[tex] \frac{42}{3} = 14[/tex]
Our slope is 14.
We can plug in any two coordinates to find b.
[tex]14(1) - b = 6[/tex]
[tex] - b = - 8[/tex]
So our equation is
[tex]y = 14x - 8[/tex]

Find the volume of the composite figure below.
Answer:
Volume of composit figure= 4834.14 cm^3
Step-by-step explanation:
here's your solution
=> Radius of hemisphere = 9 cm
==> volume of hemisphere = 2/3πr^3
==> volume of hemisphere = 2/3*22/7* 9^3
==> volume = 1526.04 cm^3
=> Radius of cylinder = 9 cm
=> Height of cylinder = 13 cm
==> volume of cylinder = πr^2h
==> volume of cylinder = 22/7*9^2*13
==> volume of cylinder = 3,308.1 cm^3
Volume of composit figure = 1526.04 + 3308.1
= 4834.14 cm^3

Answer:
y = 4x - 31
Step-by-step explanation:
Parallel slope (m) = 4

y - y1 = m(x - x1)
y + 11 = 4(x - 5)
y + 11 = 4x - 20
y = 4x - 31

Answer:
(a) 6.01 (b) 57.33
Step-by-step explanation:
(a) DF² = 10² + 12² - 2 · 10 · 12 · cos(30°)
=> DF² = 244 - 240 · cos(30°)
=> DF² = 36.154
=> DF = √36.154
=> DF ≈ 6.01
(b) [tex]\frac{12.8}{sin(63)} = \frac{12.4}{sin (B)}[/tex]
=> sin (B) = sin (63) × 12.4 ÷ 12.8
=> B = sin^-1 (sin (63) × 12.4 ÷ 12.8)
=> B = 59.67355245
180 - 63 - 59.67355245 ≈ 57.33

The world famous gambler from Philadelphia, Senor Rick, proposes the following game of chance. You roll a fair die. If you roll a 1, then Senor Rick pays you $25. If you roll a 2, Senor Rick pays you $5. If you roll a 3, you win nothing. If you roll a 4 or 5, you must pay Senor Rick $10, and if you roll a 6, you must pay Senor Rick $15. Is Senor Rick loco for proposing such a game? Explain.
Answer:
You lose $0.833 while Rick gains $0.833, and so Rick is not Loco
Step-by-step explanation:
There are six numbers on a dice. Thus, probability of rolling exactly one number = 1/6
Probability of rolling two is 2/6.
Rolling a 1 pays $25, and probability = 1/6
Rolling a 2 pays $5,and probability = 1/6
Rolling a 3 pays $0, and probability = 1/6
Rolling a 4 or 5 pays -$10, and probability = 2/6
Rolling a 6 pays -$15, and probability = 1/6
Thus,lets calculate the expected value;
EV = (25 × 1/6) + (5 × 1/6) + (0 × 1/6) + (-10 × 2/6) + (-15 × 1/6)
EV = - $0.833
This means you lose $0.833 while Rick gains $0.833, and so Rick is not Loco.
If my initial angle is 30 degrees, what is the negative coterminal angle?
Answer:
Step-by-step explanation:
Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side. For example 30° , −330° and 390° are all coterminal.
Answer:
-330°Step-by-step explanation:
Coterminal angles have a difference of 360° or multiples of 360°.
Negative coterminal angle with 30° is:
30° - 360° = -330°
