First equation:
12 + (38 - 18)2 = 12 + 20 × 2 = 52
Second equation:
(12)2 - 6(2 - 23) = 24 - 6(-21) = 24 + 126 = 150
Hope this helps.
9+13+9+10+10+9+10+10+11+9=100

Answer: 97.5
Step-by-step explanation:
Mean is calculated as total sum of values in a data set ÷ number of values in a data set
Given the data set below, add the values in the data set then divide by number of values in the data set (6)
Mean = 98 + 99 + 100+ 90 +98 +100/6
=585/6
=97.5
