Answer:
Y=0.2
X=0.9
Step-by-step explanation:
-6x+5y=1
+6x -> 5y=1 -> y=0.2
6x+4y=-10
+6x -> 12x+4y=-10
12x+4*0.2=-10
12x+0.8=-10
-0.8
12x=-10.8
x=0.9
Answer:
48
Step-by-step explanation:
65 + 70 + 73 + 49 +61 + 38 + 41 + 16 + 19 = 432
432 ÷ 9 = 48
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.

The frequency of Marla selecting an orange ball is 30%.
I did this by dividing 12 by 40, which gave me 0.3, which is 30%.
If I'm wrong do correct me.
