<span>Yes, the two events are independent because P(NF|PB) = P(NF).
I'm not 100% sure though so wait til someone else answers :)</span>
The answer would be B because he is gonna babysit for 4 hours and will charge $40 plus $4. So for the 4 hours he will earn $16 plus 40.
Answer:Area of triangle is 18cm2
There is a dotted line to show us how to do,we know the dotted means we don’t actually work that part out.
1. The bottom added together = 11,now : (11x6) ÷ 2 = 33cm2.
2.The part where there is a dotted triangle: (6x5) ÷ 2 = 15cm2.
3. 33 - 15 = 18.
The correct answer is "<span>Step 2; 6x − 8 = 12 + 2x."

The step that the student first make an error is at the 2nd step. The correct step should be 6x − 8 = 12 + 2x.
Finishing the steps:
<span>Step 1: 2(3x − 4) = 8 + 2x + 4
</span>Step 2: <span>6x − 8 = 12 + 2x.
Step 3: 4x = 20
Step 4: x = 5</span>
