Zack took out a 30-year mortgage for $70,000 at 9%. How much is his monthly mortgage payment? please explanation.. I assume $630

BartSMP [9]

Answer:

$563.24

Step-by-step explanation:

The monthly payment on a mortgage loan is found using the amortization formula:

A = P(r/12)/(1 -(1 +r/12)^(-12t))

where A is the monthly payment on a loan of P at interest rate r for t years.

Filling in the given values, we find the payment to be ...

A = $70,000×(0.09/12)/(1 -(1 +0.09/12)^(-12·30)) ≈ $563.236

The monthly payment is about $563.24.

A school wishes to accept 2000 students for their freshman class, and they expect 20,000 applications. In order to make their ad

vovangra [49]

Answer:

456

Step-by-step explanation:

Let X be the SATscore scored by the students

Given that X is normal (1000,200)

By converting into standard normal variate we can say that

$z=\frac{x-1000}{200}$ is N(0,1)

To find the top 10% we consider the 90th percentile for z score

Z 90th percentile = 1.28

$X= 200+1.28(200)\\= 200+256\\=456$

i.e. only students who scored 456 or above only should be considered.

Para armar un escritorio, Eduardo tendrá que usar 20 tarugos, los que debe cubrir completamente con una capa de pegamento. Él ca

Degger [83]

El área superficial total de los veinte tarugos es mayor que el área superficial cubierta por el pegamento.

<h3>Como determinar si la superficie cubierta por el pegamento es suficiente</h3>

En esta pregunta debemos calcular el área superficial total de los tarugos ( $A_{s}$ ), en milímetros cuadrados, y comparar el resultado con la cifra afirmada por Eduardo. El área superficial total es:

$A_{s} = 20\cdot \pi\cdot (5\,mm)^{2}\cdot (80\,mm)$

$A_{s} \approx 125663.706\,mm^{2 }$

En consecuencia, el área superficial total de los veinte tarugos es mayor que el área superficial cubierta por el pegamento. Francisca tiene la razón. $\blacksquare$

<h3>Observación</h3>

El enunciado omite las dimensiones <em>geométricas</em> de cada tarugo (5 milímetros de radio y 80 milímetros de longitud).
