The answer to this question is D.
The mean is 73.44<span>
</span>You could've found this by adding up all the values in the data set, then dividing by how many numbers were in the data set!
66+81+60+72+79+83+60+92+68 = 661
661 ÷ 9 = 73.44
Answer:
a = 0
Step-by-step explanation:
=> 3(a+4)-5(a-2) = 22
Opening Brackets
=> 3a+12-5a+10 = 22
=> 3a-5a+12+10 = 22
=> -2a+22 = 22
Subtracting 22 to both sides
=> -2a = 0
Dividing both sides by -2
We get,
=> a = 0
