Answer:

(-7)^2*∛(1728) + 14 = 49*12 + 14 = 588 + 14 = 602

Step-by-step explanation:

Primero definamos las operaciones usadas:

El cuadrado de un número N, se escribe como N^2

La raíz cubica de un número M, se escribe como ∛(M)

El producto entre dos números, A y B, se escribe como A*B

Ahora queremos plantear la operación:

"El producto entre el cuadrado de -7 y la raíz cubica de 1728, todo eso sumado 14."

Lo podemos separar en partes:

"El producto entre el cuadrado de -7 y la raíz cubica de 1728,..."

esto se escribe como:

(-7)^2*∛(1728)

Ahora, la operacion completa es:

El producto entre el cuadrado de -7 y la raíz cubica de 1728, todo eso sumado 14.

Esto se escribe como:

(-7)^2*∛(1728) + 14

Ahora debemos resolver esta operación.

sabemos que:

(-7)^2 = 49

∛(1728) = 12

Reemplazando esos dos en nuestra operación, obtenemos:

(-7)^2*∛(1728) + 14 = 49*12 + 14 = 588 + 14 = 602

Answer:

a. (29526.192 , 32155.808)

b. (29673.9301 , 32008.0699)

Step-by-step explanation:

on calculation, we find that sample mean = 30843 and sample standard deviation = 3018.504, and n=20

Sample Mean = 30841

SD = 3000

Sample Size (n) = 20

Standard Error (SE) = SD/root(n) = 670.8204

alpha (a) = 1 - 0.95 = 0.05

z critical value for 95% confidence interval:

z(a/2) = z(0.025) = 1.96

Margin of Error (ME) = z(a/2) x SE = 1314.808

95% confidence interval is given by:

Sample Mean +/- (Margin of Error) = 30841 +/- 1314.808

= (29526.192 , 32155.808)

2)when std dev of population is not known, we use sample's, but we have to use t instead of z

Sample Mean = 30841

SD = 3018.504

Sample Size (n) = 20

Standard Error (SE) = SD/root(n) = 674.958

alpha (a) = 1-0.9 = 0.1

we use t-distribution as population standard deviation is unknown

t(a/2, n-1 ) = 1.7291

Margin of Error (ME) = t(a/2,n-1)x SE = 1167.0699

90% confidence interval is given by:

Sample Mean +/- (Margin of Error)

30841 +/- 1167.0699 = (29673.9301 , 32008.0699)
