Answer:
<em>De las opciones presentadas, la correcta es la D.</em>
Step-by-step explanation:
<u>Suma de fracciones</u>
Dado que un vaso contiene 3/5 de su capacidad con leche, aún tiene libre una fracción que puede ser llenada.
Si se echa 1/7 más de leche, vamos a encontrar si la suma de las dos cantidades supera al 100% o también al número 1 que es la representación del vaso completo.
Sumemos:
Como el numerador es menor que el denominador, la fracción es menor que 1 y aún cabe más leche en el vaso. Calculando el valor aproximado:
Lo cual representa un 74% aproximadamente.
De las opciones presentadas, la correcta es la D.
No. A multiple of ten and a multiple of ten will always have at least 2 zeros.

Answer:
The answer to your question is letter C
Step-by-step explanation:
With zeros 1, 2 and -5
Process
1.- Equal the zeros to x
x₁ = 1 x₂ = 2 x₃ = - 5
x₁ - 1 = 0 x₂ - 2 = 0 x₃ + 5 = 0
2.- Write the roots as a product
(x - 1)(x - 2)(x + 5)= 0
3.- Multiply the zeros
(x - 1)(x - 2) = x² - 2x - x + 2
Simplify = x² - 3x + 2
(x + 5)(x² - 3x + 2) = x³ - 3x² + 2x + 5x² - 15x + 10
Simplify like terms and result
= x³ + 2x² - 13x + 10
Answer:One can do a two-proportion test and find that the z-value for different is 1.28 (or -1.28, depending how one sets up the test).
The p-value for that is 0.20, so by most tests this is not statistically significant.
Said another way, if there had been no change in the interval, the probability of having a repeat sample at least this different would be 0.20.
The parameter one is attempting to determine is the true proportion of adults in the US who say they like pizza.
For those who think it is 50%, it is essentially 100% likely that it is not 50% but much higher, around 75-77%.
