Probability Trees - See linked image
A good visual method for this is a probability tree.
Each set of branches represents the probabilities of on coin being removed, the second set is out of 9 as the first coin is taken and not replaced.
Multiply along the lines to work out the probability of each of the combinations.
*Even though only 'Dime Dime' is needed, it is best to do all of them as this way you are able to get all marks in an exam; you can also add up all the final values as a check to see if you are right.
The answer is <span>B. 14(m − 8)
</span>
<span>m represent the weight of the boxes that Marco lifted.
</span><span>d represent the weight of the boxes that Drew lifted.
</span><span>The boxes that Drew lifted each weighed 8 lb less than the boxes Marco lifted:
d = m - 8
So the weight of one box that Drew lifted is (m - 8). Since he lifted boxes, the </span><span>total number of pounds Drew lifted is </span> 14(m - 8)
The length of each piece of board if one piece is 18 cm longer than the other piece is 33 cm and 51cm respectively
<h3>Length</h3>
- Total length of board = 94 cm
- Length of piece 1 = x
- Length of piece 2 = (x + 18) cm
Total = length 1 + length 2
94 = x + (x + 18)
94 = x + x + 18
84 = 2x + 18
- subtract 18 from both sides
84 - 18 = 2x
66 = 2x
x = 66/2
x = 33 cm
Therefore,
Length of piece 1 = x
= 33 cm
Length of piece 2 = (x + 18) cm
= (33 + 18)
= 51 cm
