The mean, because data distribution is skewed to the right. You answer is correct
Let us say the number was x.
Mike added to it two other numbers.
First number added is 12 less than the original number.
So first number is x-12.
Second number added is 12 more than the original number.
So second number is x+12.
Now we are given that the result of adding all three numbers is 15.
Converting the information given into equation, we have:
original number + first number + second number =15
Adding like terms,
dividing both sides by 3,
x=5
Answer: So the original number that Mike thought was 5.
With calculator
sqrt(102) = 10.0995
10 = 10
3pi = 9.424
sqrt(99) = 9.9498
1.1 × 10^1 = 11
9.099 = 9.099
order is
9.099, 3π, sqrt(99), 10, sqrt(102), 1.1 × 10^1
Answer:x = 6/5
Step-by-step explanation:
The given expression is
2/3+1/5x=5/6
The Lowest common multiple of 2, 5x and 6 is 30x. We would multiply the left hand side of the equation and the right hand side of the equation by 30x. It becomes
2/3 × 30x + 1/5x × 30x = 5/6 × 30x
= 20x + 6 = 25x
Subtracting 20x from the left hand side and and the right hand side of the equation, it becomes
20x - 20x + 6 = 25x - 20x
5x = 6
x = 6/5
