5/4x+3 = x-1/4
5/4x-x = -1/4-3
1/4x = -13/4
x = -13/4.4

Donna wants to make trail mix made up of almonds, walnuts, raisins. she wants to mix one part almonds, two part walnuts, and thr

kicyunya [14]

Almons:walnuts:rasins=1:2:3

x=pounds of walnuts
y=pounds of almonds
z=pounds or rasins
2x=y
3x=z
subsitute

12x+9y+5z=15
12x+9(2x)+5(3x)=15
12x+18x+15x=15
45x=15
divide by 45
x=1/3
so
1/3 pound of walnuts
2x=y
2(1/3)=y=2/3
2/3 pounds of almonds
3x=z
3(1/3)=z
1=z
1 pound of rasins

1/3 pound walnuts
2/3 pound almonds
1 pound rasins

P(A)= .50 P(B)=.80 P(A and B)=.20 what is P(B/A)

Reil [10]

Answer:

Final answer is $P(B|A)=0.40$ .

Step-by-step explanation:

Given that P(A)= .50, P(B)=.80 , and P(A and B)=.20.

Now we need to find about what is the value of P(B/A).

So apply the formula of compound probability :

P(A and B) = P(A)*P(B/A)

Plug the given values into above formula

0.20 = 0.50*P(B/A)

0.50*P(B/A) = 0.20

$P(B|A)=\frac{0.20}{0.50}$

$P(B|A)=0.40$

Hence final answer is $P(B|A)=0.40$ .

5-1/2-3

5-1 ( 4)

2-3 (-1)

y=-4/1x+b

5=-4/1(2)+b

5=-8+b

b=-13

y=-4/1x-13

The midpoint of AB = ([?], [])<br> M = (x¹+x², ¹2²)<br> PLS HELP I WILL MARK BRAINLIEST

OlgaM077 [116]

Answer:

$\sf M=\left(-\dfrac{1}{2},0\right)$

Step-by-step explanation:

Let (x₁, y₁) = Point A = (-2, 1)

Let (x₂, y₂) = Point B = (1, -1)

$\sf Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)$

$\implies \sf Midpoint=\left(\dfrac{-2+1}{2},\dfrac{1+(-1)}{2}\right)$

$\implies \sf Midpoint=\left(-\dfrac{1}{2},0\right)$
