A) For both sets A and B, calculating the mean, range, and quartiles are a good way of measuring the center and spread. Using standard deviation may not be the best because we do not know whether the distributions are normal or not.
b) For set A, the lowest value is 63, while the highest is 86. An estimate for the mean, based on the average of these, is 74.5. Most of the 70+ values are below 74.5, so we may guess that the mean will be above the median.
For set B, the lowest is 63, while the maximum is 95. The estimated mean would be 79. But since there are more values on the 80+ and 90+ side, the median is likely to be higher than 79.
c) For set A, the mean is 74.79, while the median is 73, therefore the mean is above the median, and the prediction in part b is correct.
The answer is 25.
This is because to calculate the area of a 2 dimensional shape, you must multiply the length and the width. When the shape is a square (or a cube, if you're calculating something for a 3 dimensional shape), all side lengths will be equal. The formula for area is: Area = Length x Width, therefore you would multiply 5 with 5 to get 25, your final answer.
Expand
5x - 5 + 3 = 7x + 7
Simplify 5x - 5 + 3 to 5x - 2
5x - 2 = 7x + 7
Subtract 5x from both sides
-2 = 7x + 7 - 5x
Simplify 7x + 7 - 5x to 2x + 7
-2 = 2x + 7
Subtract 7 from both sides
-2 - 7 = 2x
Simplify -2 - 7 to -9
-9 = 2x
Divide both sides by 2
-9/2 = x
Switch sides
<u>x = -9/2</u>
