Step-by-step explanation:
(a) P = (0.3)(0.2) + (0.5)(0.6) + (0.2)(0.8)
P = 0.52
(b) (0.5)(0.6) = 0.3
P = 0.3 / 0.52
P = 0.58
B. 1/4 there's only one 2 and there's for numbers is it going to be 1/4
Respuesta:
Edad de Claudia = 5 años
Edad de María = 5 * 3 = 15 años
Explicación paso a paso:
Dejar :
Edad de Claudia = x
Edad de María = 3x
En 5 años :
3x + 5 = 2 (x + 5)
3x + 5 = 2x + 10
3x - 2x = 10-5
x = 5
Edad de Claudia = 5 años
Edad de María = 5 * 3 = 15 años
In a 30 60 90 triangle, the short side = one half the hypotenuse = 4.5
The middle side = short side * sq root of 3
So, the middle side = 4.5 * sq root of 3 (

Perimeter = 4.5 + 7.7942 + 9

The line equation in slope-intercept form is y=mx+b
You have one line with a y-intercept at 1 and a slope of -3 -> y=-3x+1
and another with a y-intercept at -1 and a slope of 
-> 
The area marked is below the first line and above the second one -> replace = with < and >:
y<-3x+1
Which is the system of linear inequalities shown in the graph
