Hello! remember you have to write complete questions in order to get good and exact answers. Here I'll explain this in a general way assuming the following table:
As you can see, x increases in steps of 1 units. So let's check the difference in y:
So we have a constant difference and we can conclude the table represents a line. Since the line passes through then y is directly proportional to x, so we can write:
Then:
Finally, the equation of the line is:
7-4x=2-9x the answer is x=1
Answer:
15
Step-by-step explanation:
Answer:
Population size:10
Mean (μ): 16
Mean Absolute Deviation (MAD): 7.2
Step-by-step explanation:
Mean absolute deviation (MAD) Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. ... Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.
Answer:
Leg1 = 9 and leg2 = 12
Step-by-step explanation:
<u>Points to remember</u>
<u>Pythagorean theorem</u>
Hypotenuse² = Base² + Height²
<u>To find the length of each leg</u>
It is given that, hypotenuse = 15 feet
Let base = x the height = x +3
By using Pythagorean theorem we can write,
Hypotenuse² = Base² + Height²
15² = x² + (x + 3)²
225 = x² + x² + 6x + 9
2x² + 6x + 216 = 0
x² + 3x + 108 = 0
By solving we get x = 9 and x -12
Therefore one leg = 9 and other leg = 9 + 3 = 12
