Answer:
0.1
Step-by-step explanation:
Solving using empirical rule formula
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
Hence, the lower bound 95% =
μ - 2σ
Mean = 0.2
Standard deviation of 0.05
= μ - 2σ
= 0.2 - 2(0.05)
= 0.2 - 0.1
= 0.1
The lower bound is 0.1
2 units i believe but not entirely sure

Answer:
342,1875
Step-by-step explanation:
Dado
Precio de compra del artículo = 219
Precio de venta cuando el descuento dado es 25% = 219 + 0,25 * 219 = 273,75
Para otorgar un descuento del 25%, este producto debe estar marcado a un precio un 25% más alto que los precios de venta = 273,75 + 0,25 * 273,75 = 342,1875
<span>hi, </span>
<span>you can determine it by seeing if y/x = a constant value, in other words if y = (a constant value) x </span>
<span>then you say that y varies directly with x, and you can see that : call the constant k </span>
<span>then y/x is supposed to be k in all values </span>
<span>6/3 = 2 </span>
<span>24/12 =2 </span>
<span>96/48 = 2 </span>
<span>384/192 = 2 </span>
<span>it worked the ratio between x and y is constant so y varies directly with x ( y = 2x) and that constant k =2 </span>
<span>p.s. you can also say that x varies directly with y but in that case it becomes x/y =constant and that constant say c is 1/2 (x = (1/2)y)) </span>
<span>hope u understand.
