8 0

Answer:

11(x - 2)

Step-by-step explanation:

Step 1:

Pulling out like terms:

2.1     Pull out like factors :

  2x - 4  =   2 • (x - 2)

Equation at the end of step 2:

 10 • (x - 2) +  (x - 2)

Step 2:

Pulling out like terms

3.1      Pull out     x-2

After pulling out, we are left with :

     (x-2) • ( 10  *  1 - (-1) ))

If P(A)=.55, P(B)=.32 And P(AuB)=.70,
son4ous [18]

Answer:

A. 0.5313

B. 0.15

Step-by-step explanation:

Given:

P(A)=0.55\\ \\P(B)=0.32\\ \\P(A\cup B)=0.70

First , use formula

P(A\cup B)=P(A)+P(B)-P(A\cap B)

to find P(A\cap B):

0.70=0.55+0.32-P(A\cap B)\\ \\P(A\cap B)=0.55+0.32-0.70=0.87-0.70=0.17

A. Use formula

P(A|B)=\dfrac{P(A\cap B)}{P(B)}\\ \\P(A|B)=\dfrac{0.17}{0.32}=\dfrac{17}{32}=0.53125\approx 0.5313

B. Use formula

P(A'|B)=P(B)-P(A\cap B)=0.32-0.17=0.15

Serjik [45]

Answer:

xA = 10 km

xB = 7.071km

Step-by-step explanation:

A/Q

p=5km

For point A

∅ = 30°

sin ∅ = p/h

sin 30° = 5/h

1/2 = 5/h

h = 5×2

h=10km

For point B

sin ∅ = p/h

sin 45° = 5/x

1/√2 = 5/x

x = 5 × √2

x = 7.071 km

.: Points A and B are 10 km and 7.071 km away from the airplane.
