You get a 15% raise at you job and now make $13.50 per hour. What was you previous
Anna71 [15]

Answer:

Original wage was $11.74/hr

Step-by-step explanation:

Let your beginning hourly rate be r.  

Then 1.00r was your previous rate of pay.

Also, 0.15r was your pay increase.

Thus, 1.15r = $13.50.  Solve this for r:

r = $13.50 / 1.15 = $11.74/hr

Check:  Does $11.74 plus the raise 0.15($11.74) come to $13.50/hr?

                         $11.74/hr     +               $1.76/hr         =   $13.50.     YES

Suppose we know that the birth weight of babies is Normally distributed with a mean 3500g and a standard deviation of 500g. What
Temka [501]

Answer:

0.21186

Step-by-step explanation:

We solve the above question using the z score formula.

z = (x-μ)/σ, where

x is the raw score = 3100g

μ is the population mean = 3500g

σ is the population standard deviation = 500g

z = 3100 - 3500/500

z = -0.8

Probability value from Z-Table:

P(x<3100) = 0.21186

The probability that a baby is born that weighs less than 3100g is 0.21186

Invertimos un capital de 250000 a una tasa de interés anual del 6% durante un cierto tiempo, ha generado unos intereses de 10000
Gnoma [55]

Answer:

Step-by-step explanation:

interés compuesto una vez al año

(250000 + 10000) = 250000(1 + 0.06)ⁿ

1.04 = (1.06)ⁿ

ln(1.04) = n(ln1.06)

n = ln1.04 / ln1.06

n = 0.673098 yr ≈ 246 días

interés compuesto continuo

(250000 + 10000) = 250000e^0.06t

1.04 = e^0.06t

ln1.04 = 0.06t

t = ln1.04/0.06

t = 0.65367 yr  ≈ 239 días
