Answer:
2
Step-by-step explanation:
The outlier here is greatly above all of the others, the mean is the sum of all of the numbers/the amount of numbers. So, if we exclude the outlier, the sum of all of the numbers would decrease
The answer is b this is because you add the angles
160.
Work out the innermost parentheses first:
{[9 x (7.3+10.7)} - 5} + [3 x (7.8 - 6.8)}
= {[9 x 18} - 5} + [3 x 1}
= {162 - 5} + 3
= 160.
