9°
Step-by-step explanation:
-6 + 15 = 9
I think the question is supposed to be 3.6/y = 1.2/2
STEP 1: Divide 1.2 by 2 to get 0.6
3.6/y = 0.6
STEP 2: Multiply each term by y and simplify
3.6 = 0.6y
STEP 3: Since y is on the right side of the equation, switch the sides so it is on the left side of the equation
0.6y = 3.6
STEP 4: Divide each term by 0.6 and simplify
y = 6
SO, THE ANSWER IS...
y = 6
Answer:
The mean absolute deviation of the data set is 6
Step-by-step explanation:
To find the mean absolute deviation of the data, start by finding the mean of the data set.
- Find the sum of the data values, and divide the sum by the number of data values.
- Find the absolute value of the difference between each data value and the mean: |data value – mean|.
- Find the sum of the absolute values of the differences.
- Divide the sum of the absolute values of the differences by the number of data values
∵ The data are 68 , 59 , 65 , 77 , 56
- Find their sum
∴ The sum of the data = 68 + 59 + 65 + 77 + 56 = 325
∵ The number of data in the set is 5
- Find the mean by dividing the sum of the data by 5
∴ The mean = 325 ÷ 5 = 65
- Find the absolute difference between the each data and the mean
∵ I68 - 65I = 3
∵ I59 - 65I = 6
∵ I65 - 65I = 0
∵ I77 - 65I = 12
∵ I56 - 65I = 9
- Find the sum of the absolute differences
∵ The sum of the absolute differences = 3 + 6 + 0 + 12 + 9
∴ The sum of the absolute differences = 30
Divide the sum of the absolute differences by 5 to find the mean absolute deviation
∴ The mean absolute deviation = 30 ÷ 5 = 6
The mean absolute deviation of the data set is 6
A function is a special relation whose every input corresponds with a single output. To be a function, each input is allowed to pair with only one output element.
For a parabola equation like above, there is no restriction in the domain. For every x value there is a unique y value.
Conclusion:
The equation is BOTH <u>a function and a relation</u>!
