3/8 has to sing
8/8 is all
all=haveto+don'thaveto
all=8/8
haveto=3/8
subsitute
8/8=3/8+don'thaveto
subtract 3/8 from both sides
8/8-3/8=5/8
5/8=don'thavetosing

answer is 5/8

How many solutions does the equation 9x-3(x+8)=6x-24
Marina86 [1]
Simplifying
9x + -3(x + 8) = 6x + -24

Reorder the terms:
9x + -3(8 + x) = 6x + -24
9x + (8 * -3 + x * -3) = 6x + -24
9x + (-24 + -3x) = 6x + -24

Reorder the terms:
-24 + 9x + -3x = 6x + -24

Combine like terms: 9x + -3x = 6x
-24 + 6x = 6x + -24

Reorder the terms:
-24 + 6x = -24 + 6x

Add '24' to each side of the equation.
-24 + 24 + 6x = -24 + 24 + 6x

Combine like terms: -24 + 24 = 0
0 + 6x = -24 + 24 + 6x
6x = -24 + 24 + 6x

Combine like terms: -24 + 24 = 0
6x = 0 + 6x
6x = 6x

Add '-6x' to each side of the equation.
6x + -6x = 6x + -6x

Combine like terms: 6x + -6x = 0
0 = 6x + -6x

Combine like terms: 6x + -6x = 0
0 = 0

Solving
0 = 0

Un productor agricola tiene que envasar huevos en cajas de 12, de 6 o de 30. Si sabemos que tiene un numero parecido a 1000 huev
musickatia [10]

Answer:

El productor tiene que envasar 960 huevos.

Step-by-step explanation:

Es necesario determinar el mínimo común múltiplo de 6, 12 y 30. En primer lugar, se determina cada número como productos de números primos:

6 = 2\times 3

12 = 2^{2}\times 3

30 = 2\times 3\times 5

El mínimo común múltiplo es:

M.C.M. = 2^{2}\times 3\times 5

M.C.M. = 60

El número total de huevos próximo a 1000 unidades es un múltiplo del mínimo común múltiplo:

n = 60\times 16

n = 960

El productor tiene que envasar 960 huevos.

By using the chebyshev inequality, find a lower bound for the probability that the average of her measurements will differ from
Daniel [21]
To find the Chebyshev's inequality, P | Xn - E(X)| <= δ/4 >= 1 - (δ^2/25)/(δ^2/16) = 1 - (16/25) = 9/25 = 0.36
The answer in this question which is the probability that the average of the physicist's measurement is within δ/4 units of the actual specific gravity is at least 0.36%
