Denotemos la cantidad de dinero que tiene Ana como. Según el problema, Betty tiene tres veces más que Ana, por lo que podemos denotar la cantidad de Betty como 3a. Carmen tiene tres veces más que Betty, por lo que la cantidad de Carmen es 3 * 3a = 9a. La cantidad total de dinero entre Ana, Betty y Carmen está dada por s/ 62. Entonces, podemos plantear la siguiente ecuación: a + 3a + 9a = 62 Resolver esta ecuación nos da el valor de a: 13a = 62 a = 62/13 = 4,77 Entonces Ana tiene s/ 4.77. Como Carmen tiene nueve veces más que Ana, Carmen tiene: 9a = 9 * 4,77 = 42,93 Entonces Carmen tiene s/ 42,93.

With the aim of identifying the presence of the feline leukemia virus (FeLV), blood samples were collected from cats sent to a private veterinary clinic in the city of Belo Horizonte. Among the animals treated, it was possible to observe that age followed a Normal distribution with a mean of 4.44 years and a standard deviation of 1.09 years. Considering this information, determine the value of the third quartile of the ages of the animals treated at this veterinary clinic. ATTENTION: Provide the answer to exactly FOUR decimal places
A box of numbered pens has 12 red, 12 blue, 12 green and 12 yellow pens. The pens for each colour are numbered from 1 to 12. There is a unique number on each pen, so no pen is exactly the same as any other pen in the box. When reaching into the box to randomly draw five pens without replacement, what is the proportion of getting exactly four pens of the same colour (Note: the numbers matter but the order does not)?
