Step-by-step explanation:
for the demoninator to get to 4 to 12 u times by 3 (4,8,12) so you times the numerator by 3, 3 times 3= 9
so its 9/12
for 6 to get to 12, you times by 2, (6,12) so times the numerator by 2, 1 times 2 is 2
9/12-6/12= 3/12
Answer:
9:7
<h3>Step by step Explanation:</h3>
i think this is the right answer
Since the average height is 60 inches and its deviation is 2 inches, one deviation to the right (or higher) is 62 inches (60 + 2). Two deviations is 64 inches, three deviations is 66 inches, and four deviations is 68 inches.
Since the average weight is 100 pounds and its deviation is 5 inches, we repeat the process from finding heights to get to 115 pounds. That takes three deviations.
The MORE deviations away, the more unusual it is. So the height (4 deviations) is more unusual than the weight (3 deviations).
Answer:In order to specify a line completely, all you need is
Step-by-step explanation:
co-ordinates of any one of the points it passes through (say, (x1,y1) ), and
its inclination (slope = m).
Its equation, by virtue of the definition of the slope then becomes,
y−y1x−x1=m
Whence, for our case,
y−2x+6=−12
which simplifies to
x+2y+2=0
