Y=Mx +b
B is 0 because that’s where the graph intercepts the y axis.
M is found by picking any two points and finding the rise and run because m is equal rise/run
Points of choice: (-2,4) and (2,-4)
=2−1/2−1 = -8/4
m is equal -2
Y= -2X
Look at the picture below to differentiate between positive and negative slopes.
Answer:
Step-by-step explanation:
The given equation :
Using logarithmic property :
The given equation will be equivalent to
Subtract 7 from both sides , we get
Divide both sides by 3 , we get
Hence, the solution is
Substitute x = 2 into y = - 6x + 9
Answer : x = 2, y = - 3
Hope this helps. - M
The mean absolute deviation (MAD), refers to the mean of the data's absolute deviations around the data's mean.
The MAD implies that Evelyn scores are more spread out than Robin scores.
The given parameters:
- <em>Robin scores = 99, 108, 102, 107 119</em>
- <em>Mean of Robin score, = 107</em>
- <em>Mean absolute deviation = 5.2</em>
- <em>Evelyn scores = 125, 137, 138, 145</em>
- <em>Mean of Evelyn score = 5.6</em>
The mean absolute deviation (MAD), refers to the mean of the data's absolute deviations around the data's mean. It implies the absolute distance from the mean of the data set.
The absolute distance of Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.
Thus, we can conclude that Evelyn scores are more spread out than Robin scores.
