I need help so I can finish my algebra hw
1 answer:
None of those are correct. the answer would be 
.
you can draw a picture of the garden space, where x is the width of the space, 3x is the length. to account for the 3 inch border you need to subtract 3 from both ends, so the width of his garden is then x-6, and the length is 3x-6.
multiplying these together, which is the formula for area, gets you.

<h3>Answer: 39</h3>
========================================================
Explanation:
You can use the nCr formula shown below
where n = 39 and r = 1. However, you could also use the identity
which basically says there are n ways to pick 1 item if you are given a choice of n items. In this specific case, we have 39 items total, and there are 39 ways to pick one item.
Probabilities are used to determine the chances of an event
- The probability of choosing a black counter is 0.6
- The probability that both counters are white is 0.16
The probability is given as:
Apply probability formula
Express as squares
Take the square root of both sides
Hence, the probability of choosing a black counter is 0.6
<h3>(b) Probability of selecting two white counters</h3>In (a), we have:
Using the complement rule, we have:
So, we have:
Evaluate
The probability that both counters are white is then calculated as:
So, we have:
Hence, the probability that both counters are white is 0.16
