En un colegio, la probabilidad de que un alumno seleccionado al azar hable inglés es de 0,20; mientras que la probabilidad de que un alumno juegue fútbol es de 0,80. ¿Cuál es la probabilidad que hable inglés y juegue fútbol?

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

differentiate (x^14(x^-2)^4with respect to the variable

the parentheses don't balance in your input.

differentiate 0 with respect to

the final answer is

0

hope this
