<h3>Answer is  3:2</h3>

Explanation

The probability of getting the correct answer is 2/5. This means there are 2 events of getting it right out of 5 events total. Since there are 2 events of getting it right, there are 5-2 = 3 events of getting it wrong.

The odds against getting the right answer is 3:2. We list the number of ways to get it wrong first, a colon, then the number of ways of getting it right.

If P = 2l + 2w, the formula to find w is .<br> If P is 30 units and l is 10 units, w is units.
Helen [10]

Answer:

<u>If P is 30 units and l is 10 units, w is 5 units</u>

Step-by-step explanation:

1. Let's check the information given to resolve the question:

P = 2l + 2w

If P is 30 units and l is 10 units, w is units

2. Replacing with the values:

P = 2l + 2w

30 = 2 (10) + 2w

30 = 20 + 2w

-2w = 20 -30 (Subtracting 2w and - 30 to both sides)

-2w = - 10

2w = 10 (Multiplying by - 1 at both sides)

<u>w = 5 (Dividing by 2 at both sides)</u>

<u>If P is 30 units and l is 10 units, w is 5 units</u>

<u>Note: Same answer than question 13938258</u>
