if a normal dice is rolled 900 times how many times is the number 4 expected
Answer:
125 times
Step-by-step explanation:
Here, we are required to determine how many times is the number 4 expected if a normal dice is rolled 900 times.
The number of times the number 4 is expected when a normal dice is rolled 900 times is; 900(1/6) = 150times.For a normal dice, there are six faces labelled numbers; 1, 2, 3, 4, 5, 6.
The probability of obtaining the number 4 each time the die is rolled is; 1/6
At the first roll of the normal dice, the probability of obtaining the number 4 is 1/6.At the first roll of the normal dice, the probability of obtaining the number 4 is 1/6.At the second roll of the normal dice, the probability of obtaining the number 4 is 1/6.At the first roll of the normal dice, the probability of obtaining the number 4 is 1/6.At the second roll of the normal dice, the probability of obtaining the number 4 is 1/6.At the third roll of the normal dice, the probability of obtaining the number 4 is 1/6.The probability of obtaining 4 in all 3 rolls is;
(1/6 + 1/6 + 1/6) = 3(1/6).
Ultimately, the number of times the number 4 is expected when a normal dice is rolled 900 times is; 900(1/6) = 150times.

Angel H and G are both are 51 degrees, and angle I is 78 degrees.
The two angles (H and G) are equal to each other, but before we know what the angles are, we must find x.
[tex]5x + 6 = 2x + 33[/tex]
[tex]3x = 27[/tex]
[tex]x = 9[/tex]
Plug in x for one equation:

Therefore,

From the sum of 3x-4y+5z,2x-7y and 9z-5y subtract -2xy-2y-2z
Answer:
5x - 14y + 16z + 2xy
Step-by-step explanation:
Given expressions:
3x - 4y + 5z
2x - 7y
9z - 5y
-2xy - 2y -2z
Solution:
Sum of 3x - 4y + 5z
2x - 7y
9z - 5y
= 3x - 4y + 5z + 2x - 7y + 9z - 5y
= 3x + 2x - 4y - 7y -5y + 5z + 9z
= 5x - 16y + 14z
Subtract -2xy - 2y -2z
= 5x - 16y + 14z - ( -2xy - 2y -2z )
= 5x - 16y + 14z + 2xy + 2y + 2z
= 5x - 16y + 2y + 14z + 2z + 2xy
= 5x - 14y + 16z + 2xy

Jesus tiene un terreno cuadrado y su hermano uno rectángulalar,El Largo Del Terreno De Su hermano mide 5 metros más que el lado que el terreno que Jesús.mientras que el ancho del terreno de Si hermano mide lo mismo que el ancho del terreno cuadrado. ¿Cual es el area total de los terrenos?
Answer:
El terreno de Jesus es cuadrado.
El terreno del hermano es rectangular.
Definimos las variables:
Lh = Largo del terreno del hermano.
Ah = Ancho del terreno del hermano
Lj = Largo del terreno de Jesus.
Sabemos que:
Lh = 5m + Lj
Ah = Lj.
Sabemos que el area de un quadrado de lado L es igual a L^2.
Entonces el area del terreno de Jesus es Lj^2.
El area de un rectangulo de largo L y ancho A es igual a A*L.
El area del terreno del hermano de Jesus es:
Lh*Ah = (5m + Lj)*Lj
= 5m*Lj + Lj^2.
