Para este problema, utilizaremos la fórmula del valor presente de una anualidad ordinaria:

VP = \dfrac{R \times (1 - (1 + i)^{-n})}{i}

Donde:
- VP es el valor presente total de la anualidad
- R es la cantidad de cada retiro (en este caso $2,500)
- i es la tasa de interés por periodo (en este caso trimestral, es decir 8%/4 = 2% o 0.02)
- n es el número total de periodos en la anualidad (en este caso serán 12 periodos para los cuatro retiros trimestrales de 2022)

Sustituyendo los valores dados en la fórmula:

VP = \dfrac{2500 \times (1 - (1 + 0.02)^{-12})}{0.02}

Simplificando:

VP = \dfrac{2500 \times (1 - 0.8194)}{0.02}

VP = \dfrac{2500 \times 0.1806}{0.02}

VP = \dfrac{451.5}{0.02}

VP = \

Por lo tanto, se deberán invertir \ 22,575 hoy, marzo 1 de 2024 para poder realizar retiros trimestrales vencidos iguales por \ 2,500 cada uno durante 2022 y obtener un interés del 8% CT.

\textbf{Respuesta:} Se deberán invertir \$22,575 hoy.

QUESTION l. An investigation has been carried out in a region to know the perception of "citizen insecurity" of its inhabitants. 1,270 people in the region were interviewed, of which 27.1% responded that it was a "serious" problem. Knowing that this opinion was previously held by 25.3% of the population of that region, we want to know if said opinion has changed significantly for a confidence level of 97.2%. Taking this statement into account, the following is requested: a) Critical value of the contrast statistic. b) Solve the hypothesis test and indicate what conclusion we can reach. c) P-value of contrast.

User One of the applications of the derivative of a function is its use in Physics, where a function that at every instant t associates the number s(t), this function s is called the clockwise function of the movement. By deriving the time function we obtain the velocity function at time t, denoted by v(t). A body has a time function that determines its position in meters at time t as S(t)=t.³√t+2.t . Present the speed of this body at time t = 8 s.
