Sam has a phone card that charges $1 to connect and $0.50 per minute. He also uses a cell phone that charges $3 to connect and $0.25 per minute. In how many minutes will calls made using the phone card and the cell phone cost the same?
Answers
1 + .50 = 1.50
1.50 2.00 2.50 3.00 3.50 4.00 4.50 5.00
3.25 3.50 3.75 4.0 4.25 4.50 4.75 5.0
Sam has a phone card that charges $1 to connect. If it is 50 cents a minute he would be able to call for 2mintues on this phone. His or her cell phone CHARGES $3 and it is 25cents per mintue. which would be.. 12mintues

El costo de los rodamientos de soporte 950 es de $ 5,800
Step-by-step explanation:
Esperamos una gráfica lineal de costo contra el número de rodamiento de respaldo.
Un punto en este diagrama tendrá una representación como (número de demoras, costo)
Ahora, a partir de la pregunta, podemos identificar dos puntos; (300,3200) y (700,4800)
Generalmente, la ecuación de una línea recta tiene la forma
y = mx + c
donde m es la pendiente y c es la intersección en y
Lo que esto significa en esta línea es que tenemos dos cosas para calcular, que es la pendiente de la línea y la intersección de la línea. Usando los dos puntos podemos calcular estos.
matemáticamente, la pendiente se puede calcular como;
tenemos m = (4800-3200) / (700-300) = 1600/400 = 4
Como conocemos la pendiente, el modelo lineal ahora se convierte en
y = 4x + c
Para obtener el valor de la intersección con el eje y, podemos usar cualquiera de los dos puntos. Digamos que queremos usar el primer punto (300,3200)
3200 = 4 (300) + c
3200 = 1,200 + c
c = 3200-1200
c = 2000
Así la ecuación se convierte
y = 4x + 2000
Ahora usemos los parámetros definidos en la pregunta, tenemos;
C = 4x + 2000
donde C es el costo yx es el número de rodamientos de soporte
Ahora queremos calcular el costo de 950 rodamientos
Simplemente usamos la ecuación que hemos modelado donde en este punto, x = 950
C = 4 (950) + 2000
C = $ 5,800

1. -8, 4, 8
2. -20, 20, -40
3. 50, -50, 25
Answers
Answer:
-8, -40, -50
Step-by-step explanation:
if f(x)=2x+5, g(x)=x², h(x)= -2x
h(g(f(x))) = h(g(2x+5)) = h((2x+5)²) = h(4x²+20x+25) = -2(4x²+20x+25)
= -8x²-40x-50

Probability of being male: 550/1000 = 0.55
Probability of earning over $50,000: 870/1000 = 0.87
0.55 x 0.87 = 0.4785
Probability of being male and earning over $50,000: 485/550 = 0.8818
C) No, P(being male | the person earns over $50,000) ≠ P(being male)
Based on the date given "being male" and "earning over $50,000" are NOT mutually exclusive events. That is "No, P(being male | the person earns over $50,000) ≠ P(being male)" (Option C)
What are mutually exclusive (or independent) events?
Two events are independent or mutually exclusive if they are distinct from one another and cannot alter the reaction of one another.
Calculation
- Probability of being male: 550/1000 = 0.55
- Probability of earning over $50,000: 870/1000 = 0.87
=0.55 x 0.87
= 0.4785
Thus, probability of being male and earning over $50,000
= 485/550
= 0.8818
Hence, we can state that P(being male | the person earns over $50,000) ≠ P(being male)
