Respuesta:

20/31

Explicación paso a paso:

Para obtener respuestas a la Pregunta, contamos el punto ya que representa el número de estudiantes:

El número total de estudiantes se puede obtener contando todos los puntos en el diagrama de venn = 31

Número de estudiantes que juegan fútbol solos = número de puntos en la parte F del diagrama de Venn = 4

Número de estudiantes que juegan béisbol solos = número de puntos en la parte B del diagrama de Venn = 2

Número de estudiantes que juegan fútbol y béisbol = 5

La probabilidad de que un estudiante elegido al azar no juegue fútbol o béisbol:

El número de puntos que quedan fuera de los círculos se refiere al número de estudiantes que no participan en ninguno de los dos deportes = 20

P (sin béisbol o fútbol) = 20/31

What is a million times all the numbers in the world

Well, there isn’t really an end for numbers...

However; The biggest number referred to regularly is a googolplex (10googol), which works out as 1010^100. That isn’t the end to numbers but it is a huge one. We will replace that with ‘all the numbers in the world’.

106 is the exponent equivalent to 1 million

So your question would be:
106 x 1010^100 =

However I don’t believe there is a calculator that large.

Please help me find the slope of the line !!

LenaWriter [7]

The slope of the line is 3/2. That would be letter B. You take two points from the graph and subtract them from each other to find the slope. Hope this helps!

Micah went to the mall with $50 to spend. After spending $8.75 on lunch, he

Delicious77 [7]

Answer:

Step-by-step explanation:

Since he spends 8.75 on lunch, we subtract that from the total, 50 dollars. When we subtract that, we get 41.25 left. The variable is not clear for the sweatshirt cost and how much money you can spend on it, so I will call it x. Since 41.25 is the total amount you can spend on a sweatshirt, anything exactly that amount or less is okay. So, our answer is x is less than or equal to 41.25. (Less than or equal to is the < with a slash underneath)
