Answer:
743.25m^2
Step-by-step explanation:
Area of triangle = 1/2bh
= 1/2 x 30 x 26
= 390
Area of semi circle = 1/2 πr^2
= 1/ 2 x 3.14 x 15 x15
=353.25m^2
= 390 + 353.25
= 743.25m^2
Its 144. you just subtract the 121 from 265.
Answer:
B) is correct; on average, each bag of candy has a weight that is 2.6 oz different than the mean weight of 5 oz.
To find the mean absolute deviation, we first find the mean. Find the sum of the data points and divide by the number of data points (without the outlier, 21, in it):
(10+3+7+3+4+6+10+1+2+4)/10 = 50/10 = 5
Now we find the difference between each data point and the mean, take its absolute value, and find their sum:
|10-5|+|3-5|+|7-5|+|3-5|+|4-5|+|6-5|+|10-5|+|1-5|+|2-5|+|4-5| =
5+2+2+2+1+1+5+4+3+1 = 26
We now divide this by the number of data points:
26/10 = 2.6
This is a measure of how much each bag of candy varies from the mean.
