Answer:
5/16=s/32
Step-by-step explanation:
What we know:
- a school team has 80 swimmers
The ratio of 7th grade swimmers to every swimmer in their school (counting all the grades) is 5:16. Write a proportion of this for a value of s.
a ratio can also be expressed in a fraction by simply putting it from x:y to x/y
so, the ratio 5:16 can also be expressed as 5/16.
note: let sgs represent seventh grade swimmers.
also, let x represent the value of the equivalent amount of swimmers (in the denominator that serves as a value for the proportion of 5/16.
we need to find:
5 sgs/16 swimmers = s amount of sgs/x
5/16=s/x
equivalent fractions could literally be anything, just multiply that ratio by a value equal to one; ex 4/4, or 16/16, or 2/2.
the simplest proportion is to multiply 5/16 by 2/2.
5/16*(2/2)=s/x
10/32=s/x
so s=10 and x=32 but we only need to know x cuz your problem doesn't have a box to answer the s=10.
so... 5/16=s/32.

If P(A) = 0.5, P(B) = 0.4, and P(A or B) = 0.8, find P(A and B).
Answers
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%
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?
Answers
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.

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)
