A mini-golf course is determining the par score for each of its holes. The dot plot shows the number of strokes required to plac e a ball in the ninth hole for a sample of 31 players. Which measure of center is best to use to determine the expected number of strokes required for the ninth hole
1 answer:
The mean is the unit of center that may be used to predict how many strokes will be needed to complete the ninth hole.
The data is almost symmetrical , making the mean the best option.
What is symmetrical data?
Asymmetric communications refers to any system where, when averaged over time, the data speed or amount is different in one direction from the other.Asymmetry is defined as the lack of precise similarity between two pieces. A fiddler crab's body is asymmetrical , as evidenced by the fact that one of its claws is larger than the other. Absence of a standard unit of measurement between two things or amounts; incomprehensibility. So the more about symmetrical visit.

Answer:
x= -4 & y=-12
Step-by-step explanation:
multiply y=3x by 2
giving you 2y=6x
subtracting 2y=x+20 from 2y =6x
=> 5x=-20
dividing through by 5
=> x=-4
put x=-4 into y=3x
=> y=3(-4)
<em>y</em><em>=</em><em>-12</em>
Step-by-step explanation:
5 x − 7 = 8 5x-7=8 5x−7=8. Add 7 to both sides. Simplify 8 + 7 8+7 8+7 to 1 5 15 15.
