Case 1: Probabilities cannot add up to a number greater (or less) than 1. This would mean there is greater than a 100% chance of something happening which just doesn't make sense. 0.4 + 0.4 + 0.3 = 1,1
Case 2: You cannot have a negative probability. That is claiming that there is a -10% chance of an event happening, there is at the very least a 0%. Despite them "adding" up to 1, the negative probability makes no sense.
Hope I helped!
Answer:
9 months
Step-by-step explanation:
Given
Fabulous fitness charges a one-time fee of $90 and an additional $25 per month
let the number of months be x
and the total charges be y
y= 25x+90---------1
Wonder weights charges a one-time fee of only $ 27 dollars but charge an additional $32 each month
let the number of months be x
and the total charges be y
y= 32x+27------------2
Required
The value of x, that is the number of months
Step two:
Equating both equations we have
25x+90=32x+27
collect like terms
25x-32x=27-90
-7x=-63
7x=63
divide both sides by 7
x= 63/7
x= 9 months
Since the 3 of them are like terms, we have to ADD all 3 of them.
4x+2x+7x= 13x
The length of model is ......15 inch
if the scale factor is 1/20
it means 1/20=15/h
h=12*15=300
Answer:
La razón geométrica de mujeres a varones es de 3 mujeres por cada 4 hombres.
Step-by-step explanation:
El enunciado es incorrecto, su forma correcta es: <em>En una escuela hay 196 estudiantes, de los cuales 84 son mujeres. La razón geométrica de mujeres a varones que estudian en dicha escuela es:</em>
Es sabido que la especie humana solo tiene dos formas en un sentido biológico: hombre y mujer. Si 84 de los 196 estudiantes son mujeres, entonces 112 son hombres. En consecuencia, la razón geométrica de mujeres a varones es de 3 mujeres por cada 4 hombres.
