A professora Luísa observou que o numero de meninas de turma dividido pelo numero de meninos dessa turma e 0,48. Qual e o menor
saw5 [17]

Respuesta:

37 estudiantes

Explicación paso a paso:

El número de niños dividido por el número de niñas = 0,48

Dejar :

x = número de niños; y = número de niñas

Tenemos ;

x / y = 0,48

Conversión a decimal;

0.48 es equivalente a 48/100

Reduciendo a la forma más simple:

48/100 = 12/25

Comparando:

x / y = 12/25

x = 12; y = 25

El menor número posible de estudiantes:

x + y = 12 + 25 = 37 estudiantes

(08.02)a pair of equations is shown below. 3x − y = 9 y = −2x + 11 if the two equations are graphed, at what point do the lines
mixas84 [53]
3x - y = 9
y = -2x + 11

3x - (-2x + 11) = 9
3x + 2x - 11 = 9
3x + 2x = 9 + 11
5x = 20
x = 20/5
x = 4

y = -2x + 11
y = -2(4) + 11
y = -8 + 11
y = 3

solution (where the lines intersect) is (4,3)

Which of the following demonstrates how the 20 is calculated using the<br> combination pattern?
ZanzabumX [31]

Answer:

D

Step-by-step explanation:

The diagram shows Pascal's triangle. Pascal's triangle is a triangular array of the binomial coefficients.

The entry in the n^{th} row (start counting rows from 0) and k^{th} column (start counting columns from 0) of Pascal's triangle is denoted by

C^n_k=\left(\begin{array}{c}n\\ k\end{array}\right)

Coefficient 20 stands in 6th row, then n = 6 and in 3rd column, so k = 3.

Hence,

20=C^6_3=\left(\begin{array}{c}6\\ 3\end{array}\right)=\dfrac{6!}{3!(6-3)!}
