Answer: 98
Why? The angle is alternate exterior angle making it even to the angle labeled 98
Answer:
2.4
Step-by-step explanation:
We have to find the mean first
Now we have to find deviations.
Note that the deviations are calculated by subtracting the mean from the value. The distance is always positive so the deviations will be positive
Value Deviation
2 2-4.5 = |-2.5| = 2.5
4 4-4.5 = |-0.5| = 0.5
7 7-4.5 = 2.5
2 2-4.5 = |-2.5| = 2.5
3 3-4.5 = |-1.5| = 1.5
7 7-4.5 = 2.5
9 9-4.5 = 4.5
3 3-4.5 = |-1.5| = 1.5
1 1-4.5 = |-3.5| = 3.5
7 7-4.5 = 2.5
The last step is to find the mean of deviations.
The mean absolute deviation of given data set is 2.4 ..
Answer:
Given :
A man buys a few number of books at RS 72 each and a few number of pens at RS 25 each .
To Find :
If he buys 11 articles and pays RS 510 altogether,find the number of each article bought by him .
Solution:
Total no. of article = 11
Let x be the no. of books bought for RS 72 each
So, No. of pens bought for RS 25 each = 11-x
Cost of x books = 72x
Cost (11-x) pens = 25(11-x)
He buys 11 articles and pays RS 510 altogether
So,72x+25(11-x)=510
72x+275-25x=510
47x=510-275
x=5
So,No. of pens bought for RS 25 each = 11-x=11-5=6
Hence 6 pens and 5 books were bought by him.
