Any fraction that would simplify down to -3/7
Remember, what you do to the denominator, you must do to the numerator.
For example:
-6/14 is an answer choice, for: (-6/14)/(2/2) = (-3/7)
Hope this helps
Answer:
3/8
Step-by-step explanation:
1/8 + 1/4 = 1/8 + 2/8 = 3/8
Note that 1/4 = 1/4 * 2/2 = 1*2 / 4*2 = 2/8
Answer:
Step-by-step explanation:
Given
Transformation: 180 degrees clockwise around the origin
Required
Determine the new coordinates Z'
<em>When a point (x,y) is rotated 180 degrees clockwise around the origin, the new point is: (-x,-y)</em>
<em></em>
So:
Then:
Answer: The length of each side is 7 yards.
Step-by-step explanation: To solve the perimeter, you add each of the sides. A square has 4 sides of equal length. Divide 28 yards by 4 yards. Therefore, the answer is 7 yards per side.
Using it's concept, it is found that the mean absolute deviation of 2.8 means that the heights differ from the mean by an average of 2.8 inches.
<h3>What is the mean absolute deviation of a data-set?</h3>
- The mean of a data-set is given by the sum of all observations divided by the number of observations.
- The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.
- The mean absolute deviation represents the average by which the values differ from the mean.
In this problem, the mean is given by:
M = (65 + 58 + 64 + 61 + 67)/5 = 63.
Hence the mean absolute deviation is given by:
MAD = (|65-63| + |58-63| + |64-63| + |61-63| + |67-63|)/5 = 14/5 = 2.8.
The mean absolute deviation of 2.8 means that the heights differ from the mean by an average of 2.8 inches.
