Answer:
No Real Solutions
Step-by-step explanation:
So we have:
First, determine the domain restrictions. The expression under the radical cannot be less than 0. Therefore:
Therefore, our final answers must be greater than or equal to 3:
Now, going back to the original equation, subtract x from both sides:
Now, square both sides:
Distribute:
Subtract 4x and add 12 to both sides:
This isn't factor-able. Let's use the quadratic formula. a is 1, b is -4 and c is 12:
Substitute:
Simplify the radical:
The number under the radical is negative. In other words, there are no real solutions.
Answer:
y=-1/2n+44
Step-by-step explanation:
The number of bean stalks, n, represents the x values
The yield, y, represents the y values
After reading the problem, we have two coordinates: (30,29) and (32, 28) Because this problem is asking for y=mn+b, we have to find the slope. How do we find the slope? We do so by using the slope formula y2-y1/x2-x1. Now let's input the coordinates into this formula.
1.) 28-29/32-30 = -1/2
Let's plug -1/2 into y=mn +b
2.) y=-1/2n+b
Now we have to find what b ( y intercept) equals. To find B, we plug a coordinate into x and y. Let's use (30,29)
3.) 29 = -1/2(30)+b
29 = -15 +b
44 = b
We have now found the linear relationship form for this problem: y=-1/2n +44

Answer:
Explanation:
Hola. Puesto que tu pregunta está en español, te responderé en el mismo lenguage.
Estas son las posibilidades dadas por la combinación moneda/dado
Número de combinaciones
Moneda: prenda
Cara: vestido 1 de 2: 1/2
Sello: falda 1 de 2: 1/2
Dado: color
Par: negro 3 de 6: 3/6
Impar: café 3 de 6: 3/6
En total son 2 × 6 resultados: 12 (incluye resultados repetidos, no son todos diferentes entre sí)
¿Cuántas combinaciones tienen vestido y color negro?
Es decir: moneda = cara y dado = par
Por tanto, la probabilidad de vestido negro es:
- 3 de 12 = 3/12 = 1/4 ← respuesta
Hay otras formas de resolverlo. Por ejemplo;
Como los resultados de lanzar la moneda y el dado son independientes:
- P(Vestido∩negro) = P(Vestido) × P(Negro)
- P(Vestido) = 1/2
- P(Negro) = 3/6 = 1/2
- P(Vestido) × P(Negro) = 1/2 × 1/2 = 1/4 ← mismo resultado
Answer:
A = 180 customers.
Step-by-step explanation:
Let the number of customers that made additional purchases be A.
Given the following data;
Percentage = 72% = 72/100 = 0.72
Total number of customers = 250
To find the number of customers that made additional purchases;
A = 0.72 * 250
A = 180 customers.
Therefore, 180 customers made additional purchases on Wednesday.
