Trabajando 10 horas por día, en 6 días se producen 3000 ruedas.

<h3>¿Cuántos dias tardarán en fabricar 3000 ruedas si trabajan 10 horas diarias?</h3>

Sabemos que trabajando 8 horas, en 5 dias producen 2000 ruedas.

El número total de horas que trabajan en esos 5 dias es:

(8 horas)*5 = 40 horas

Entonces se producen 2000 ruedas en 40 horas, es decir, la razon de trabajo es:

(2000 ruedas)/(40 horas) = 50 ruedas por hora.

Ahora, sí en la fabrica trabajan 10 horas al día, entonces van a producir:

10h*(50 ruedas por hora) = 500 ruedas por día.

El número x de días que deben trabajar para producir 3000 ruedas es:

x*(500 ruedas por dia) = 3000 ruedas

x = (3000 ruedas)/(500 ruedas por dia) = 6 dias.

Trabajando 10 horas por día, en 6 días se producen 3000 ruedas.

Sarah is doing research on the average age of first-year resident physicians. She wants her estimate to be accurate to within 1

WINSTONCH [101]

Answer: The number of first-year residents she must survey to be 95% confident= 263

Step-by-step explanation:

When population standard deviation ( $\sigma$ ) is known and margin of error(E) is given, then the minimum sample size (n) is given by :-

$n=(\dfrac{z^*\sigma}{E})^2$ , z* = Two-tailed critical value for the given confidence interval.

For 95% confidence level , z* = 1.96

As, $\sigma$ = 8.265, E = 1

So, $n= (\dfrac{1.96\times8.265}{1})^2 =(16.1994)^2\\\\= 262.42056036\approx263\ \ \ [\text{Rounded to the next integer}]$

Hence, the number of first-year residents she must survey to be 95% confident= 263

Answer:

B) 1 < x < 13

Step-by-step explanation:

use triangle inequality theorem which states that the sum of any two sides must be greater than the third side

let x = third side

6 + 7 > x; x < 13

6 + x > 7; x > 1

x + 7 > 6; x > -1

there will always be one inequality which produces a negative value which you can exclude from your answer because a length cannot be negative

Help me please thank you

ratelena [41]

Answer:

a) 98 degrees.

b) 8 degrees.

Step-by-step explanation:

supplementary angles: 2 angles that add up to 180 degrees.

a) to find the supplementary angle, all we have to do is:

180 - 82 = 98 degrees

Complementary angles: 2 angles that add up to 90 degrees.

b) to find the complementary angle, all we have to do is:

90 - 82 = 8 degrees

Hope that helped : )
