Answer:
x=2
Step-by-step explanation:
Convert the Y to 3x since we know that y=3x.
You would get x+3x=8.
Add the x and 3x to get 4x
Then, you would get 4x=8.
Divide by 4 on both sides to get x=2.

Answer: The standard deviation was calculated incorrectly.
Step-by-step explanation:
- The standard deviation measures the dispersion of the data values from the mean value.
It cannot be negative , because it is the square root of the variance .
We add all squared deviations from the data points away from the mean and (then divide it by the number of data values) to evaluate variance.
Since , any squared number cannot give a negative result.
⇒ Standard deviation cannot be negative.
⇒The standard deviation was calculated incorrectly.
Rest other things (given in options) can not be interpreted on the basis of given information.
