Hi!
Let's start with the mean.
The mean is all the numbers added together, divided by how many numbers there are.
13+16+16+10+6+12+4+12+16=105
there are 9 numbers so..
105/9 = 11.7
The mean is 11.7
Find the median.
The median is the number in the middle of the data set when the numbers are in numerical order.
4, 6, 10, 12, 12, 13, 16, 16, 16
The median is 12.
Find the mode.
The mode is the number that is repeated the most.
4, 6, 10, 12, 12, 13, 16, 16, 16
The mode is 16
Find the range.
The range is the difference of the smallest number from the biggest number.
16 - 4 = 12
The range is 12
The answer is 11.7, 12, 16, 12
Hope this helps! :)
The answer would be 7 1/2 because you would add 1 1/2, 2 1/2,3 1/2 so there you go
When two triangles<span> are </span>congruent<span> they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there</span>
Answer:
1/6*1/2= 1/12
Answer is 1/12
Step-by-step explanation:
hope this helps (:
First, let's calculate the mean and the mean absolute deviation of the first bowler.
FIRST BOWLER: <span>8,5,5,6,8,7,4,7,6
Mean = (Sum of all data)/(Number of data points) = (8+5+5+6+8+7+4+7+6)/9
<em>Mean = 6.222</em>
Mean absolute deviation or MAD = [</span>∑(|Data Point - Mean|]/Number of Data Points
MAD = [|8 - 6.222| + |5 - 6.222| + |5 - 6.222| + |6 - 6.222| + |8 - 6.222| + |7 - 6.222| + |4 - 6.222| + |7 - 6.222| + |6 - 6.222|]/9
<em>MAD = 1.136</em>
SECOND BOWLER: <span>10,6,8,8,5,5,6,8,9
</span>Mean = (Sum of all data)/(Number of data points) = (<span>10+6+8+8+5+5+6+8+9</span>)/9
<em>Mean = 7.222</em>
Mean absolute deviation or MAD = [∑(|Data Point - Mean|]/Number of Data Points
MAD = [|10 - 7.222| + |6 - 7.222| + |8 - 7.222| + |8 - 7.222| + |5 - 7.222| + |5 - 7.222| + |6 - 7.222| + |8 - 7.222| + |9 - 7.222|]/9
<em>MAD = 1.531
</em>
The mean absolute deviation represents the average distance of each data to the mean. Thus, the lesser the value of the MAD is, the more consistent is the data to the mean. <em>B</em><em>etween the two, the first bowler is more consistent.</em>
