To find the median, order the numbers in the data set from least to greatest (or greatest to least, either one works) and then find the number in the middle. If there are 2 numbers in the middle, find their mean.
Step 2: Find the median (middle number). The median is the number in the center. Count in from each side equally to find the middle number. 76, 78, 82, 84, 88, 90, 92, 94, 98, <span>100 </span>78, 82, 84, 88, 90, 92, 94, 98 82, 84, 88, 90, 92, 94 84, 88, 90, 92 88, 90 88 and 90 are the middle numbers. Since there are 2 numbers in the middle, we must find their mean.
Step 3: Find the mean of the 2 middle numbers. Mean is also known as average. To find this, add up the numbers and then divide by the amount of numbers there are. In this case, that means adding 88 and 90 then dividing their sum by 2. This can be represented by the equation (88 + 90) ÷ 2. 88 + 90 = 178 178 ÷ 2 = 89 89 is the final answer, it is the median.
The spinner is divided into four equal sections: 2, 4, 7, 9. This represents 4 possibilities
If the spinner is spun twice, the sample space is:
For product less than 30, the number of outcomes is shown below:
The number of outcomes that have a product less than 30 = 10
The sample space that shows possibilities of an odd number combination:
The number of outcomes that contains at least one odd number = 12
The number of outcomes that have a product less than 30 and contain at least one odd number is shown below. These outcomes are outcomes circled in both cases shown above,
The outcomes circled represents the number of outcomes that has a product less than 30 and contains at least one odd number
