Answer:
72 ft²
Step-by-step explanation:
base=9
height=8
9*8=72
Area of parallelogram= base*height
Answer:
12.3 grams
Step-by-step explanation:
When a constant value is added to each data element in a distribution, the maen changes by that constant but the standard deviation stays the same. This is because the standard deviation is a measure of how distant the data are from the mean. When a constant value is added to each of them, the mean also gets the increment. Hence, the distance from the mean is maintained.
However, if the data were multiplied by a constant factor, then the standard deviation will be multiplied by the same factor as well as the mean.
Therefore, the standard deviation from the question remains the same as before, 12.3 grams.

Step-by-step explanation:</h2>
From the given graph, we can know two points:
Using the slope intercept form of the equation of a line, we get:
Where the slope is 
and the y-intercept is 
From mathematics, we know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept. So, from the options, the second equation is:
And the slope intercept form of this equation is:
So the slope is and the y-intercept is 
, the systems formed by these two equations has no solution.
