If P(A) = 0.5, P(B) = 0.4, and P(A or B) = 0.8, find P(A and B).
Answer:
P(A and B)=0.2
Step-by-step explanation:
P(A or B) represents mutually exclusive events, which mean they cannot occur at the same time. For example, you can't turn your head left and right at the same time. Their probabilities would be added as a result.
P(A and B) represents events that do occur at the same time, so the probabilities are multiplied. P(A and B)=P(A)*P(B)=0.5*0.4=0.2 or 20%

The given expression will have no solution.
What is linear equation?A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.
Given an expression, 9x - 18 = 3(3x - 6)
In the given expression, both LHS and RHS are equal, therefore it will have no solution.
Hence, The given expression will have no solution.

From what I understand it wants us to solve "9x-4>95" so that's what I'll do.
add 4 to each side
9x>99
divide each side by 9
x>11 is the solution to 9x-4>95
For 4x+10>54
subtract 10 from each side

Answer:
Slope: 6
Y-intercept: 4
Equation: y=6x+4
Step-by-step explanation:
For slope you do change in y over change in x so its 10-4/1-0 in this case which gets you 6/1 or 6 for your slope
It crosses the y-axis at (0,4) so your y-intercept is 4
The base equation is y=mx+b m is slope b is y-intercept so you plug in your values and get y=6x+4

Answer:
x = 18
Step-by-step explanation:
2x + 3(4) - 1 = 47
Begin by combining your like terms
2x + 12 - 1 = 47
2x + 11 = 47
Isolate your variable (x) by using inverse operations
2x = 36
x = 18

los miembros de un club social se pueden agrupar en sin que ninguno quede suelto, por parejas, por trios y por grupos de 7. ¿ cuantos miembros tiene el club, sabiendo que son mas de 80 pero menos de 90?
Answer:
El club tiene 84 miembros.
Step-by-step explanation:
El mínimo común múltiplo (mcm) es el número positivo más pequeño que es múltiplo de dos o más números. Es decir, el mínimo común múltiplo de dos números a y b es el número más pequeño que es múltiplo de a y múltiplo de b. Recordar que los múltiplos son el resultado de multiplicar un número por todos y cada uno de los números naturales.
Para calcular el mcm se descompone los números para escribirlos como un producto de números primos. Para descomponer un número se divide el número sucesivamente entre números primos hasta llegar a 1. La descomposición es el producto de las potencias de los números primos, siendo sus exponentes el número de veces que se ha dividido por dicho primo.
El mínimo común múltiplo se obtiene escogiendo todos los factores (comunes y no comunes), elevados a la máxima potencia. Es decir eliges todos los factores, pero los que se repitan serán elevados a la máxima potencia.
En este caso, los miembros de un club social se pueden agrupar, sin que ninguno quede suelto, por parejas, por tríos y por grupos de 7. Para calcular la cantidad de miembros que tiene el club, entonces debes calcular el mcm entre los números 2,3 y 7
No podemos descomponer los números como producto de primos porque ya son números primos., por lo que el mínimo común múltiplo es el producto de comunes y no comunes al mayor exponente:
mcm (2,3,7)= 2*3*7= 42
Pero sabes que los miembros son más de 80 pero menos de 90, por lo que calculas un múltiplo del mcm obtenido.
Múltiplo de 42= 2*42= 84
El club tiene 84 miembros.

Which of the following graphs below is the graph of a function?
(1)
(3)
(2)
(4)
The graph that represents a function is graph (1)
How to determine the graph?The attached graphs represent the given parameters
From the attached figure, we can see that there are four graphs
Each of the four graphs represented different functions
As a general rule,
A graph that represents a function must pass the vertical line test
The vertical line test is such that:
If a line is drawn from the x-axis, it must touch the curve not more than one times
The graph that passes this test is graph (1)
This is so because it is a quadratic graph
Hence, the function graph is (1)
