Total number of campers = 20
Total number of teams = 5
⇒ Number of campers in each team = Total number of campers ÷ Total number of teams
⇒ Number of campers in each team = 20 ÷ 5
⇒ Number of campers in each team = 4
Number of recorders in each team = 1
⇒ Number of searchers in each team = Number of campers in each team - Number of recorders in each team
⇒ Number of searchers in each team = 4 - 1
⇒ Number of searchers in each team = 3
Hence, there will be 3 searchers in each team
It is 240 because 8 bags of hot dog buns plus 30 packages of hot dog buns would equal 240.
<span>In order to find the standard deviation, we first have to calculate the mean (average) of the numbers. To get this we add all the numbers together and then divide by 12 since there are 12 numbers. The mean = 782. Next, we take each number and subtract the mean, taking the result and squaring it. For this we get: 6724, 2209, 10404, 11664, 729, 1764, 12544, 9, 529, 71824, 1444, 1024. Now we sum all of these up and take the average by dividing the sum by 12. Doing this we get 120868/12=10072. The last step is the take the square root of that number to get the standard deviation. The final result is 100.</span>
