$ 11,137
Explicación paso a paso:
Como no se nos dice qué encontrar, también podemos encontrar el beneficio obtenido por la venta de 351 unidades de radio.
Dado
Función de costo C (x) = 43x + 1850
Función de ingresos R (x) = 80x
Obtener la función de ganancias
P (x) = R (x) - C (x)
P (x) = 80x - (43x + 1850)
P (x) = 80x - 43x - 1850
P (x) = 37x - 1850
Si se fabrican 351 radios, la ganancia obtenida se calculará como se muestra a continuación:
P (351) = 37 (351) - 1850
P (351) = 12,987-1850
P (351) = 11,137
<em>Por lo tanto, la ganancia obtenida de las ventas de 351 radios es de $ 11,137</em>

Multiply all terms by the same value to eliminate fraction denominators
Answer:
84
Step-by-step explanation:
The tens digit can be 8, 6, 4, or 2 since the ones digit can only be a whole number, so that means it can only be 4, 3, 2, or 1.
If we try all possible combinations (84, 63, 42, 21) and subtract 36 from them, you will find the answer is 84. (84 - 36 = 48)
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. The area of the rectangle is:
Where 
is the width and 
is the length.
2. Based on the data given, solve for the width and then substitute the values of the length and the values of the area. Therefore, you have:
The answer is the second option:
Answer:
The probability that a randomly selected programmer major received a salary less than 38000 is 0,3085
Step-by-step explanation:
We will assume that the salaries are Normally distributed. Lets call X the salary of a random major programmer in dollars. We want the pprobability of X being less than 38000. For it, we will standarize X. Lets call W the standarization, given by the formula
Lets denote 
the cumulative distribution function of the standard normal variable W. The values of are well known and they can be found in the attached file. Now, lets calcualte the probability of X being less than 38000 using
Since the density function of a standard normal random variable is symmetric, then 
The probability that a randomly selected programmer major received a salary less than 38000 is 0,3085.
