Answer:
-9.661
Step-by-step explanation:
In the given equation, a and b are negative. The values of a and b are given. If you insert the values into the given formula, the values become negative because of "-" in front of the a and b values.
-a + (-b) = -6.05 + (-3.611)
Because the second value is negative, the plus sign references to adding BOTH negative values together so it is just the same as saying:
-6.05 - 3.611
This gives you -9.661
Hope this helps!
Answer: the answer is the second option.
Step-by-step explanation:
You first have to distribute the negative to the second pair of parenthesis. So the new equation would be 2n-4-4n+3. Next you combine like terms. So your final answer is -2n-1.
The mean is 4.93333 (3 is repeating)
Explanation
So mean is just the sum of the numbers divided by the number of terms
So we would solve this by adding up all terms as shown here
10.6 + 4 + 4 + 6 + 4 + 1 = 29.6 = sum
Then we will divide the sum by the number of terms which is 6 in this case to get our mean as shown here
29.6 / 6 = 4.9333
The mean is 4.9333 (3 is repeating)
