En un pequeño taller de reparación de zapatos, se ha cronometrado el tiempo que se tarda el señor González en poner las tapas a las suelas, y los tiempos de Reloj se muestran en la siguiente tabla (donde la actividad normal es 100). Calcule el tiempo normal representativo (TNr) para la actividad. Utiliza la formula siguiente:T N r igual sumatorio desde J igual 1 hasta N de fracción numerador T R i espacio multiplicación en cruz espacio F A i entre denominador N fin fracciónTNr: Tiempo normal representativo.

Seleccione una:8.7636.1837.673

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !

step-by-step explanation:

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
