Answer:
0.143
Step-by-step explanation:
From counting principle, we can say that:
There are 7! ways of the 7 people to arrive first. Any one of them can come first. But, what is the probability that Xerxes with arrive first?
We take that Xerxes is the first one to arrive, then from the 7 - 1 = 6 remaining people, they can arrive in 6! ways. So
Probability Xerxes arrives first = 6!/7! = 0.1429
Rounding to 3 decimal places, it will be:
<u>Probability Xerxes arrives first = 0.143</u>
Expression for percent of survey participants who chose fishing =
Explanation:
Total number of boys = 60
Number of boys who took part in survey = 18 + 29 =47
Number of boys who chose fishing = 29.
Percentage of an outcome = (Number of favorable outcome/ Total number of outcome) x 100
Percentage of boys who chose fishing = (29/47)x100
Expression for percent of survey participants who chose fishing =
Hope I helped! :)
well it would make sense to say that the longest fish is 12in longer than the shorter fish because if you take 21in (the longest fish) and subtract 9 (the shortest fish) you would get 12.
Hope that helped pls give brainlist
Answer:
Step-by-step explanation:
We are given the area of a rectangle is 1 inch square.
You can find the area of a rectangle if you know the dimensions. Let's pretend the dimensions are w and l.
So we given w*l=1.
Now the perimeter of a rectangle with dimensions l and w is 2w+2l.
We want to express P=2w+2l in terms of w only.
We are given that w*l=1 so l=1/w (just divided both sides of w*l=1 by w).
So let's plug it in for l (the 1/w thing).
So .
