Answer:
The probability of the percentage of thefts in a random sample of 400 would be greater than or equal to 3 is given by P (z> 1.09) = 0.1379
Step-by-step explanation:
The statistic
z= p^- p / √pq/n
is used to measure the difference between the sample and population proportions.
Here p^= 12/400= 0.03
p= 0.022 q= 1-0.022=0.978
and n=400
Putting the values
Z= 0.03-0.022/√0.022(1-0.022)/400
Z= 0.008/√0.022(0.978)/400
Z= 0.008/0.00733
z= 1.090
We have to find the probability of the percentage of thefts in a random sample of 400 would be greater than or equal to 3
or
Mathematically
P (z> 1.09)= 1- P (z≤1.09)
= 1- 0.8621 ( from the z area table)
= 0.1379
Which of the following shows two expressions that are NOT equivalent?
a
4(3x + 8) and 12x + 32
b
6(7x + 8) and 42x + 48
c
9(3x + 6) and 28x + 54
d
5(6x + 7) and 30x + 35
Answer:
C
Step-by-step explanation:
C because 9(3x+6) equals to 27x+54.
Therefore 27x+54 does not equal to 28x + 54

Jose desea que la puerta de su cuarto solo se pueda abrir hasta cierta posicion (ver figura). Si uno de los angulos de la abertura mide (x + 5)° y la otra (2x + 13)°. Cual seria la medida del angulo de la abertura menor?
Answer:
La medida del ángulo de la abertura menor es 29°.
Step-by-step explanation:
Podemos calcular la medida del angulo de la abertura menor hallando el valor de "x" en la siguiente ecuación:
[tex] (x + 5) + (2x + 13) = 90 [/tex] (1)
Dado que en la figura podemos observar que la suma de ambos ángulos de abertura resulta en un ángulo rectángulo.
Al resolver la ecuación (1) tenemos:
[tex] x + 2x = 90 - 13 - 5 [/tex]
[tex] 3x = 72 [/tex]
[tex] x = 24 [/tex]
Ahora, podemos encontrar los ángulos de abertura.
Angulo de abertura menor:
[tex] x + 5 = 24 + 5 = 29^{\circ} [/tex]
Angulo de abertura mayor:
[tex] 2x + 13 = 2*24 + 13 = 61^{\circ} [/tex]
Por lo tanto, la medida del ángulo de la abertura menor es 29°.

Find the volume of a 1 km3 body of water in m3, and select the correct units.
Answer:
1,000,000,000 [tex]m^3[/tex]
Step-by-step explanation:
1 kilometer is equal to 1000 meters, and 1 [tex]km^3[/tex] is 1 km * 1 km * 1 km
Therefore,
1000m * 1000m * 1000m = 1,000,000,000 [tex]m^3[/tex]

Answer:
a = [tex]4\sqrt{3}[/tex]
b= 4
Step-by-step explanation:
It's a 30-60-90 triangle based on the given picture. A right triangle too
Use sine, cosine, and tangent to solve for the side.
To find b, you can use sin(30) = b/8 because sin(angle) = opposite/hypotenuse.
OR you can use the rule for 30-60-90 triangle, which is x for short leg, 2x for hypotenuse, and [tex]x\sqrt{3}[/tex] for long leg
So either way, b = 4
To find a, you can use cos(30) = a/8 because cos(angle) = adjacent/hypotenuse.
OR you can use the same rule, 30-60-90 triangle to save time
a will end up = [tex]4\sqrt{3}[/tex]

Multiply 16 by 1/8 and you get 2
Answer:
128
Step-by-step explanation:
For every mile, there are 8 signs. (Sign for every 8th of a mile). There are 16 mikes so 8x16=128
8(39 + 11)
a (8 +39) * (8 + 11) = 893
b. (8 x 39) * (8 x 11) = 27456
C. (8 +39) + (8 + 11) = 66
d. (8 x 39) + (8 x 11) = 400
Answer:
option D is the correct answer
En un estacionamiento cobran $12.00 la hora y $3.00 por 1/4 de hora ¿Cuánto debo pagar si estacione mi coche a las 11.15am y los saque a las 3.00pm
Ayuda plis doy coronita.
Answer:
$45
Step-by-step explanation:
De 11.00am a 3.00pm hay 4 horas de diferencia.
Eso seria 12x4=$48
Pero necesitamos restarle 1/4 de hora, por lo que se estaciono a las 11.15am y no a las 11.00am
1/4 de hora o 15min= $3.00
48-3=45

John is watching a baseball game. So far, 6 out of 8 batters have gotten a hit. What is the
experimental probability that the next batter will get a hit?
Help again plz I need work shown
Answer:
E = J, and X = 11
Step-by-step explanation:
Okay. So we know that the total degree in a triangle is 180 degrees. We see that the two triangle are similar (E = J) so J = 80, S = 36, and P = 4x +20
We can make this into the equation 80 + 36 +4x +20 = 180
We then simplify 136 + 4x = 180
Isolate 4x 4x = 180 - 136
4x = 44
--- ----
4 4

x = 11
A bus makes a stop at 2:30, letting off 10 people and letting on 8. The bus makes another stop ten minutes later to let off 5 more people. How does the number of people on the bus after the second stop compare to the number of people on the bus before the 2:30 stop?
Answer:
7 less people
Step-by-step explanation:
You let 10 people off then you let 8 on meaning there are 2 less people. Then 5 more people get off meaning there are 7 less people
Answer:
7 less people

Answer:35 51 98
Step-by-step explanation:
Answer:
Hello! Thanks for posting the question again!
Anyways here are the answers...
d = 35 because its a vertical angle
e = 51 because its a vertical angle
Now to find f we have to add these up then subtract by 360 then ÷ by 2 so 51 + 51 + 35 + 35 = 172 360 - 172 = 188 188 ÷ 2 = 94 so f = 94
Solve for x.
3x < 12
Answer:
X can be anything below 4
Answer:
x should be 1,2, or 3
Step-by-step explanation:
because if you take 3x4 it would be 12 (the same) so that's wrong. so it would have to be lower than that
