Q. The following data points represent the number of chicken nuggets on each family member's plate.1,3,0,6,?If the mean of the data set is 3 chicken nuggets, find the missing number of chicken nuggets.nuggets
Understand the problem: Understand the problem. We are given a set of numbers representing the number of chicken nuggets on each family member's plate: 1,3,0,6,?. We are also told that the mean of this data set is 3 chicken nuggets. We need to find the missing number that will make the mean of the data set equal to 3.
Calculate the sum: Calculate the sum of the given numbers. We add the known numbers of chicken nuggets together: 1+3+0+6=10.
Use the formula: Use the formula for the mean. The mean is the sum of all numbers divided by the count of numbers. We know the mean is 3, and there are 5 numbers in the data set (including the missing number). Let's denote the missing number as m. The formula for the mean is (sum of all numbers) / (count of numbers) = mean, which translates to (10+m)/5=3.
Solve for the missing number: Solve for the missing number m. We multiply both sides of the equation by 5 to isolate m on one side: 5×((10+m)/5)=5×3, which simplifies to 10+m=15.
Subtract to find value: Subtract 10 from both sides to find the value of m: 10+m−10=15−10, which simplifies to m=5.
